PREFACE

Lift-laparoscopy is a new concept of gasless laparoscopy with a reusable abdominal wall lifting system, which provides the surgeon with the necessary space and vision comparable to that of pneumoperitoneum laparoscopy. This concept avoids several typical intraoperative problems of pneumoperitoneum laparoscopy. By utilizing flexible and valveless trocars, conventional instruments, and standard surgical techniques and moreover avoiding disposables, lift-laparoscopy is a cost effective procedure with benefits for patients, surgeons, hospitals, and the health system. Lift laparoscopy, on the one hand, is a simple, effective, and economical introduction to operative laparoscopy and, on the other hand, extends the indications of minimal invasive surgery. Conventional instruments, which have been developed and modified over a very long period, allow the surgeon, in contrast to laparoscopic instruments, to use tactile sense and palpation. Complications during the blind Veress needle or trocar insertion such as vascular lesions or intestinal injury are virtually excluded by this technique. Problems and complications of the iatrogenic insufflation of carbon dioxide (pneumothorax, pneumomediastinum, pneumopericardium, air embolism, massive subcutaneous emphysema) are completely excluded. Physiologically, gasless laparoscopy is less invasive than pneuomoperitoneum insufflation and allows the performance of laparoscopic surgery in at-risk patients, e.g. those with heart insufficiency or lung obstruction, as well as in pregnancy. The ability to utilize operative laparoscopy under regional anesthesia has become a new challenge. Lift-laparoscopy continues to pursue the concept of laparoscopy as minimal invasive surgery; however, it offers simplification and cost-effectiveness and extends the range of application. This atlas represents a procedural guide, and not a textbook, as endoscopy is a visual topic. It offers the experienced laparoscopic and laparotomic surgeon an excellent guide to starting lift-laparoscopic procedures and, based on this description, to developing personal skills in a reasonable learning time.

WHAT MAKES GASLESS LAPAROSCOPY SUPERIOR TO PNEUMOPERITONEUM

In modern surgical practice, the surgical procedure known as keyhole surgery or minimally invasive surgery permits operations to be performed which formerly would have necessitated the use of large incisions and instruments. Keeping the surgical wound as small as possible was for a long time the aim of surgeons. Therefore, surgical techniques were continually being refined in order to gain access, with the minimum of adverse effects, to the site of disease. In gynecology, endoscopic investigations of the abdominal sex organs, such as the uterus, fallopian tubes, and ovaries, have a long history. Operations using the endoscope were a routine procedure in the diagnosis of various gynecologic conditions. In the 1970s laparoscopy was performed mainly for diagnosis or for tubal ligation. Thanks to the pioneer Professor Kurt Semm, from Kiel, more and more indications were established in Germany and worldwide. Today, laparoscopic procedures to treat benign manifestations in the ovaries and fallopian tubes (extrauterine pregnancy, ovarian cysts) as well as in the uterus (myomas) are standard procedures carried out as a routine measure in endoscopic centers. The advantages of endoscopic operations for malignant cases cannot yet be definitively elucidated, which is why such operations are being conducted on an experimental basis in very few hospitals.

ADVANTAGES OF ENDOSCOPY Large surgical wounds are avoided using endoscopy. Therefore, there is markedly less wound pain after surgery. The patient recovers and becomes mobile more quickly; hence, the hospital stay is considerably shortened and indeed procedures can even be carried out in many cases on an outpatient basis. The cosmetic result is considerably better since only small scars remain. Wound healing disorders are seen less often after endoscopic operations than after open abdominal surgery, and there are fewer problems due to adhesions and scars.

RISKS AND DISADVANTAGES OF ENDOSCOPIC OPERATIONS However, like all operations, endoscopic procedures also pose certain risks such as, for example, hemorrhage, organ injury, or infection. Moreover, it can come to light in the course of an endoscopic procedure that conventional surgery is warranted. Endoscopic procedures necessitate insufflation of the abdominal cavity with carbon dioxide in order to obtain a sufficient view of the surgical field and grant the surgeon enough space to work. This causes a considerable build-up of pressure in the abdominal cavity and reduces the body temperature due to the cold gas, which in turn causes pain that in some cases can persist for several days, radiating to the shoulder and neck regions; these manifestations can prolong and complicate the recovery period. Moreover, the gas is held responsible for further side effects whose implications have not yet been adequately clarified. For example, there are increasingly more reports in the literature about incidences relating to carbon dioxide, which is converted in the body to carbonic acid. Long operations using carbon dioxide may lead, above all in older and less healthy patients, to a decrease in the pumping action of the heart or to overloading the organism with carbonic acid, and this in turn can cause acidosis of all organ systems. Insufflated gas can in very rare cases lead to gas accumulation in the vascular systems of the lungs (gas embolism), heart (decrease in coronary blood supply), and the kidneys (poorer perfusion), or to the accumulation of carbon dioxide in the subcutaneous tissue of the skin (emphysema). While such side effects of carbon dioxide are extremely rare, they can prove fatal (kidney failure, heart attack, pulmonary embolism). Typical complications of an endoscopic procedure can occur while inserting the Veress needle – for gas insufflation – or the secondary trocars. This ‘insufflation needle’ is pierced ‘blindly’, i.e. without visual control, into the abdominal cavity. After the abdominal cavity has been filled with gas, the first trocar for the optic is inserted (also without visual control). Both can in rare cases cause injury to vessels or organs (for example the bladder, intestines, stomach, and others), and this in turn can trigger emergency situations (e.g. bleeding) warranting immediate action. An undetected bowel injury following coagulation often results some time later in acute ileus and massive infection. Endoscopic operations are clearly more difficult, and are therefore performed by only a few centers. By working with overly long, specially modified instruments, the surgeon loses tactile perception. The instruments are unfamiliar; they have the most diverse gripping systems and small graspers. All this detracts from precision during surgery. Only a very few surgeons develop the ability to operate in the abdominal cavity with only indirect visual contact, i.e. looking at the monitor. Therefore, the learning curve associated with endoscopic surgical techniques is very long. The complication rate for 2

endoscopic procedures is also higher than in open surgery, especially in the case of surgeons who are not yet optimally trained. This is also one of the reasons why, following the initial euphoria, stagnation can be noted in the spread of endoscopy. In order to avoid gas loss via the instruments, special trocars with valves were developed. The instruments themselves consist of multiple tubular and shaft systems which mimic the rotary and angled movements of the hand. To avoid gas loss while changing the instruments (for example between scissors and graspers), multi-functional instruments were developed. Industry has to make massive investments to manufacture these instruments, which is why the costs incurred for such instruments are much higher than in the case of conventional instruments. Endoscopic instruments are more laborious when it comes to maintenance and processing. Due to the myriad tubular systems, special washer-disinfectors must be purchased to clean these instruments and eliminate contaminants based on body secretions and blood, which could cause infection. For the past 75 years (since the introduction of laparoscopy with carbon dioxide) industry has been trying, in close cooperation with endoscopic surgeons, to overcome the problems emanating from endoscopic procedures using gas. In the meantime, a very important market segment has therefore developed which, by continually developing newer instruments and equipment, makes endoscopic procedures using gas safer but also more expensive. The costs are spiraling due to, among other things, the use of special thread and suture materials, the widespread use of disposables, such as titanium clip systems, and the use of suturing devices and angled instruments; all this calls into question the benefits of endoscopic procedures. Professor Axel Perneczky, a neurosurgeon from Mainz, made the following statement regarding endoscopic surgery: ‘Keyhole surgery can be likened to a situation where we try to sew on a button on the bed linen in the bedroom with a tweezers through the keyhole of the front door; moreover, the rooms are full of furniture, around which we have to maneuver the tweezers …’ This is a corresponding quotation by the present author on the development and introduction of gasless laparoscopy: ‘Keyhole surgery can also be likened to a situation where we use a ladder to try to come in through a closed window of a bedroom on the first floor, although the front door is wide open …’

ADVANTAGES OF GASLESS ENDOSCOPY Gasless laparoscopy continues to pursue the concept of a minimally invasive operating method, however offering the principle of simplification, cost-effectiveness, and a wide range of application. This technique is based on the principles of minimally invasive operating methods, combined with the conventional technique used in ‘open’ abdominal surgery. The gasless technique reduces all of the aforementioned disadvantages, risks, and

complications of gaseous endoscopic surgery to a minimum, but retains, however, all the advantages of laparoscopy such as small scars, better appearance, less pain, quicker recovery, shorter hospital stay, etc. The method thus offers progress (the combination of the latest techniques of endoscopic surgery) by taking a step back (proven and established, conventional abdominal surgery techniques).

Advantages for the Patient By dispensing with insufflation using carbon dioxide, there is considerably less pain after surgery. Essentially, the shoulder pain observed after endoscopic procedures is avoided or greatly reduced. The patient needs fewer painkillers compared to laparoscopy with gas. The recovery period is shorter, with the patient returning to normal activity faster than after laparoscopy with gas; for instance, the recovery period after a hysterectomy is only approximately 2 weeks. The operation is safer and more precise because one can dispense completely with the long and unfamiliar instruments. The risk of infection posed by inadequately cleaned endoscopic instruments and by different tubular and pumping systems is eliminated. The serious complications associated with ‘blind’ insertion of the Veress needle or trocars into the abdominal cavity are avoided, because in gasless laparoscopy the abdominal cavity is accessed under visual control. Complications relating to clips, suturing systems, or electrical coagulation, e.g. injuries to the ureter during an endoscopic hysterectomy, are avoided. The not yet foreseeable late complications caused by titanium clips remaining in the body, which must still be investigated, can be avoided. All aforementioned side effects, risks, and complications caused by carbon dioxide are circumvented, so that in addition to young and healthy patients, older or at-risk patients can also be operated on using the gasless method. This technique also makes it possible to perform endoscopic procedures under regional anesthesia, something that was not hitherto possible because of the massive pressure from the pneumoperitoneum in the abdominal cavity, which causes pain and organ compression (diaphragm, lung). Operations can also be conducted in pregnant women using gasless laparoscopy, as there is no pressure build-up, caused by gas, on the growing uterus (miscarriage, decreased perfusion of the placenta and of the baby). Gasless laparoscopy carried out in pregnancy avoids acidity of the blood of the fetus so that organ damage can be prevented, and, moreover, the operation can be performed without general anesthesia. Domenico D’Ugo, an anesthesiologist from Rome, stated in 1997 at the International Symposium on Gasless Laparoscopy in Gynecology: ‘The use of carbon dioxide is almost the only reason for exclusion of risk patients from laparoscopy, who in truth would be the only ones to benefit from the minimally invasive procedure …’ 4

Advantages for the Surgeon The dangerous complications which are typical of endoscopic surgery, resulting from ‘blind’ insertion of the Veress needle for gas insufflation or of the first trocar, are avoided. In addition to special instruments, the surgeon can also use traditional surgical instruments. Accordingly, sutures can be applied using the tried and tested needle and thread method instead of clip and suture apparatus or electrical coagulation, which are expensive or can cause complications and whose benefits have not yet been clarified. Inadequate suture techniques that often occur during endoscopic treatment also do not represent a problem for the gasless method, as conventional suture techniques with needle and thread are used without a problem. It is often seen that, when closing up the myometrium after the enucleation of an intramural myoma, endoscopic suture techniques can fail. As a result, the inadequate adaptation of the myometrium has been stated as a cause for possible rupture of the uterus during pregnancy and childbirth. Tried and tested surgical techniques which have proved themselves over decades can also be used, thus enhancing precision and safety and shortening the operating time. Unlike when using the long endoscopic instruments, the surgeon preserves tactile manual perception and can thus feel what he is cutting, holding, or compressing. With the magnification conferred by the endoscope, the operation evolves more precisely and more safely. Gasless laparoscopy also simplifies the removal of samples and tissue from the abdominal cavity, as these can be morcellated with a scalpel or scissors. As the organ or part of an organ is immediately removed, the loss of features associated with the organ, such as myomas, is counteracted. During a gas laparoscopic operation, the organ is in most cases removed at the end of the operation to prevent any gas loss through the extended opening during the removal procedure. Also, the learning curve associated with the gasless technique for the surgeon is markedly shorter, because he needs only to learn how to interact with the monitor, since the surgical technique remains the same as that practiced in open abdominal surgery, and is therefore easier.

Advantages for the Healthcare System Minimally invasive operations using laparoscopy with carbon dioxide are about seven times more expensive than laparotomy. Minimally invasive operations using gasless laparoscopy are more cost-effective as they dispense with systems that render laparoscopy with gas expensive. Instruments can be cleaned in the same way as hitherto; no special washerdisinfectors are required.

Conventional instruments last considerably longer: they do not break as often as those instruments used for the gas method, and need not be repaired or replaced so often. Neither is it necessary to continue using every novel instrument and technique that comes on the market so that the safety and maneuverability of gas laparoscopy can be improved. With the gasless method no disposables are used, such as titanium clips and special threads, which are enormously expensive. By combining the minimally invasive technique (short hospital stay and recovery period) with the cost-effectiveness of the gasless method, this method of surgery is overall markedly more favorable than laparoscopy with gas. This technique is simple and easy to learn, and hence more surgeons, who have so far not performed endoscopic surgery due to its inherent difficulties, can employ the technique, and therefore more patients will benefit from the minimally invasive surgical method. Especially in the developing countries of our world where, because of the lack of appropriate equipment and the high costs of devices and instruments, endoscopic surgical techniques were scarcely encountered or introduced, patients can be operated on with laparoscopy using the lifting technique.

CONCLUSION Gasless laparoscopy using the Abdo-Lift™ abdominal wall retractor system combines the advantages of minimal invasive surgery with the advantages of laparotomy, eliminating at the same time the disadvantages of both methods. The method thus fulfills the target criteria, as defined by Scheidel, for checking innovative treatment concepts. As patients experience less postoperative pain after the same operation, the therapy is more successful (cost-effective). Also, a therapy result which is at least equally as good is achieved at a lower cost (cost-utility) and the benefit of the therapy for the patient is increased, as both the costs and the complications are reduced (cost-benefit).

COMPLICATIONS AND PROBLEMS DUE TO CARBON DIOXIDE AND PNEUMOPERITONEUM: PATHOPHYSIOLOGIC EFFECTS OF CARBON DIOXIDE INSUFFLATION

PATHOPHYSIOLOGIC EFFECTS OF CARBON DIOXIDE INSUFFLATION Whilst instruments and devices have become more advanced, the principle of the CO2 pneumoperitoneum has not changed for decades, and it is precisely the carbon dioxide which limits the scope of this operative technique. The occurrence of possible side effects and complications is more significant in the cases of older and higher-risk patients and longer operations. Problems relating to CO2 laparoscopy such as hypothermia with increased postoperative pain, but also hemodynamic and metabolic effects such as CO2 absorption and CO2 intravasation coupled with an increase in pCO2, have been described by Chernlack et al. and Alexander and Brown.1,2 The CO2 is known to produce metabolic acidosis and hypercapnia as well as hypoxemia in the tissues, as described by Wolfe et al., Taura et al., Wittgen et al., and McLaughlin et al. in their cases of endoscopic cholecystectomy.3–6 The pneumoperitoneum itself leads to an increase of the intraabdominal pressure, which causes an elevation of the diaphragm and can result in hyperventilation. The pneumoperitoneum may lead to compression of the vena cava, causing the cardiac output and volume to be reduced and the central venous pressure to be increased, resulting in increased vascular resistance in the arterial circulation, as noted by Brown et al., ben-David et al., and Sharma et al.7–9 With the increased popularity and usage of operative laparoscopy, an increase in indications along with prolonged operating times and operations on older patients or high-risk patients occurred. Unfortunately, this was followed by more reports of acute organ failure8 or fatal complications caused by CO2 insufflation,9–11 as described by several anesthetic and intensive care departments.

If one, however, looks at experimental studies, these show that gasless laparoscopy offers clear advantages compared to pneumoperitoneum laparoscopy. A randomized study of renal excretion and the electrolyte metabolism during gasless interventions and gas laparoscopy carried out in pigs12 showed that a significant reduction of creatinine clearance and urinary excretion occurred during and after CO2 laparoscopy. Also, a significant increase in the serum aldosterone occurred, an indication of a disorder of the renin–angiotensin system due to underperfusion of the kidneys, causing a reduction of the sodium and potassium level in the urine. Apart from other physiologic advantages of gasless laparoscopy discussed in this study, the authors concluded that gasless laparoscopy clearly offered better results than gaseous laparoscopy with regard to renal hemostasis. To increase the safety of laparoscopic surgery, the authors even recommended monitoring the urine electrolytes and the urine volume during a gas laparoscopy process and, in particular, in the case of longer operations. Another experimental study by Woolley et al.,13 carried out in pigs, clearly showed that gasless laparoscopic surgery also achieved significantly better pulmonary and systemic hemodynamics compared to a CO2 pneumoperitoneum. During endoscopic surgery, lasting several hours, more than 100 liters of cold CO2 may circulate through the abdominal cavity, causing hypothermia; the body temperature can sink by 3°C during this process. A further problem of CO2 laparoscopy is possible contamination of the CO2 with viruses, bacteria, rust, metal dust, or Teflon™14 in the insufflation device or the hose system. This problem occurs, in particular, in countries in which it is not usual to produce medical CO2. Recent studies by Koninckx in Leuven15,16 showed in animal trials that, depending on the duration of the operation, CO2 stimulates the formation of adhesions. Finally, to complete the list, one should also mention the studies by various work groups carried out in animals to solve the problem of the spread of malignant cells, apparently caused by modulation (acidosis) of the peritoneum by the CO2 gas.17 This in turn led to statements such as that minimally invasive surgery is maximally invasive from a physiologic point of view, and that consequently patients subjected to endoscopy should be carefully selected to minimize such complications.8–11

OTHER COMPLICATIONS DURING PNEUMOPERITONEUM LAPAROSCOPY Apart from possible complications caused by the CO2 gas, problems with the pneumoperitoneum in laparoscopic surgery should also be mentioned. Complications arising from blind insertion, such as vascular lesions or intestinal injury, occur relatively seldom, but can, however, be serious. 8

COMPLICATIONS AND PROBLEMS DUE TO CO 2 AND PNEUMOPERITONEUM

Also, a pneumothorax, a pneumomediastinum, a pneumopericardium, an air embolism, or a massive subcutaneous emphysema could result.18,19 Absolute contraindications to laparoscopy using a pneumoperitoneum are cardiac insufficiency and lung obstruction, whilst relative counterindications are pregnancy, diaphragmatic hernia, and obesity. Every surgeon knows about the dangers of a collapsing pneumoperitoneum at the moment a hemorrhage occurs. In most cases, the suction irrigation system also fails, making it impossible to see the area, whilst the surgeon tries to pinpoint the hemorrhage using suction and irrigation. As a result of the escaping pneumoperitoneum, the space in the upper abdomen is lost (reservoir for intestinal loops), causing the intestines to move back from the upper abdomen into the pelvis, and the precisely located site of hemorrhage once again disappears from view. If the bleeding from the vessel covers the lens system, which, anyway, is constantly misted up (temperature difference between that of the irrigation solution and body temperature), the surgeon will experience hampered vision and this will lead to confusion. It is also nearly impossible to grasp the bleeding vessel with the tiny ends of a laparoscopic forceps or even ligate the vessel, so that conversion to open surgery can hardly be avoided. None of these problems is encountered in gasless laparoscopic surgery, and hence we must strongly consider that gasless laparoscopy is indeed much safer, more physiologic, and more effective than pneumoperitoneum laparoscopy.

PATIENT POSITIONING AND ANESTHESIA

PATIENT POSITIONING The patient is placed in a lithotomy position with the buttocks extended over the end of the table. The thighs should be flexed to allow good instrument manipulation. Attention should be given to proper positioning of the patient’s legs to avoid peroneal nerve injury during lengthy procedures. Shoulder braces must be used to make the steep Trendelenburg position possible during surgery. If shoulder braces are used they should be placed over the acromion to avoid possible brachial plexus injury. It is advisable that both arms should be tucked along the patient’s body to prevent brachial plexus injury and provide more space for the surgeon. If monopolar electrosurgery is to be used during the procedure, a ground electrode for the unipolar instruments must be properly placed over the patient’s thigh, and full surface contact of the electrode must be assured. It is recommended that the patient be covered with a sterile drape before any other procedure to ensure mounting the Abdo-Lift™ system in sterile conditions. The patient is draped with leggings and a laparoscopy sheet. On the right side of the operating table only one layer of covering material may be used. Straight bladder catheterization is performed for short laparoscopic procedures, or a Foley catheter is placed in the bladder if prolonged surgery is anticipated. The bladder has to be emptied to minimize any potential injury during ancillary trocar placement. After placement of a cervical tenaculum, a uterine manipulator is inserted into the cervix and uterine cavity to enable manipulation of the uterus during the procedure. A rectal probe can also be introduced for manipulation and better visualization of the rectum, and identification of the recto-vaginal septum during extensive laparoscopic resection. For gasless laparoscopy it is recommended that the bowel be prepared as for laparotomy, in the case that not only a diagnostic procedure but also operative surgery is to be performed. If extensive surgery is likely to be carried out, and bowel manipulation or injury anticipated, as in the case of extensive adhesions or endometriosis, it is advisable to administer a mechanical bowel preparation prior to surgery. The use of a nasogastric tube is not strictly mandatory, as no blind puncture to insert a trocar is to be performed.

ANESTHESIA If general anesthesia is chosen and the operating time is scheduled to be more than 90 minutes, the anesthetist should perform a TIVA (total intravenous anesthesia) without the use of N2O, as nitrous oxide begins to inflate the bowel after 90–120 minutes, with the consequence that the distended bowel is placed in the pouch of Douglas and might disturb parts of the operation. If there is no possibility to perform a TIVA, a bladder catheter can be inserted into the rectum during the procedure to evacuate air from the bowel. In cases of spinal, epidural, or combined spinal/epidural anesthesia it is recommended to leave the patient with both hands free, since psychological stress is high and the patient is unable to move any other part of the body. To help the patient relax a CD player or DVD player is very useful. To prevent intraoperative pain or nausea, especially in anxious patients, sedative drugs can be administered.

CREATION OF ABDOMINAL WALL ELEVATION

The technique is similar to the Hasson open procedure; however, the skin incision in the lower umbilical fold is only 12–15 mm. By the use of specially developed S-hooks the abdominal cavity can be reached without the difficulties encountered during the Hasson technique. All steps are performed under visual control, including the first incision. To a greater extent than in pneumoperitoneum laparoscopy, lift (gasless)laparoscopy becomes difficult when severe adhesions are present around the periumbilical area. If adhesions are found in the lower abdominal quadrant, the retractor can be inserted first in the direction of the upper abdominal cavity or in a direction where no adhesions are present. After inspecting the abdominal cavity with the endoscope, an area free from adhesions must be located where a trocar can be introduced enabling an initial adhesiolysis to be performed. Sometimes a low-pressure (8–10 mmHg) pneumoperitoneum is necessary to perform adhesiolysis, prior to insertion of the abdominal wall retractor. In some corpulent patients, it might be necessary to change the position of the retractor to the upper abdomen for visualization of the organs from the upper abdominal quadrant. A steep Trendelenburg position (up to 30°) allows the bowel to slide to the upper abdominal quadrant that serves as a ‘reservoir’ for the intestine. Routinely, two ancillary ports can be introduced in the suprapubic region. In contrast to gas laparoscopy, these ports might be placed very close to each other (both trocars are medial from the epigastric vessels!) and about 1 cm under the pubic hairline, since using conventional curved instruments makes it possible to reach all pelvic organs and structures. After a few weeks the pubic hair covers the incisions and the cosmetic results obtained by this technique are better than in pneumoperitoneum laparoscopy.

TERMINATION OF THE LIFT (GASLESS)-LAPAROSCOPIC PROCEDURE

When the procedure is completed, the entire abdominal cavity is checked for hemostasis. Then, the ancillary trocars should be withdrawn under visual control. To prevent hernia formation, the fascia of the umbilical and the ancillary ports should be closed. Closure of the ancillary ports should be performed under endoscopic visualization. Afterwards, the retractor can be removed from the abdominal cavity by turning it counter-clockwise. The abdominal cavity can then be elevated by one hand while the other hand is holding the endoscope. The trocar sheath is removed from the incision while the optic remains in the abdomen. Withdrawing the endoscope slowly out of the abdominal cavity ensures that no bowel or omentum is pinched in the incision. The fascia is sutured, and, after approximating subcutaneous tissue, the skin is adapted by sutures. The AbdoLift™ is then removed piece by piece from the operating table and prepared for cleaning and sterilization.

ENUCLEATION OF OVARIAN CYST WITHOUT RUPTURE USING ENDOBAG

In the case of enucleation of an ovarian cyst, it is very important to remove the cyst or the ovary without rupture and spillage of the cystic contents, especially in the case of suspicious findings. Conventional surgical methods, which are very easy to apply using lift (gasless)-laparoscopy, avoid spillage. Blunt dissection with a sponge and countertraction with a conventional forceps allow a surgical technique that makes it possible to avoid spillage in most ovarian tumors. Even if there is a microrupture, it is easy to continue surgery as one is able to grasp the rupture site with a long forceps longitudinally and continue the procedure of enucleation, or apply a ligature over the ruptured cyst capsule. In liftlaparoscopy the removal of tissue specimens is less problematic as there is no interaction with gas leakage, and the endobag can be grasped and opened with conventional curved instruments, allowing the bag to be held open around the instruments. Closure of the ovarian capsule is performed with conventional suture material and a curved needle and conventional needle driver.

MYOMECTOMY

Fibroids that are located intramurally are sometimes difficult to enucleate. After an incision is made through the myometrium with bipolar scissors, the enucleation of the myoma can be performed using bipolar forceps or bipolar scissors and a regular grasping forceps. In the case of bleeding, conventional plastic suction tubes from open surgery can be used to evacuate blood clots, and rinse out water and smoke. Additionally a forceps with a sponge can control the bleeding. After removing the fibroid, the myometrium must be sutured. In the case of intramural fibroids, adequate closure of the myometrium is necessary. In contrast to gas laparoscopy, conventional needle drivers can be used to manipulate suture material with a curved needle for adequate closure of the myometrial tissue. We perform closure of all layers with as few stitches as necessary to achieve an adequate and functional closure of the myometrial wound. With this technique, we avoid wound healing problems due to infections and necrosis that may occur with numerous stitches. Using this technique there is not much coagulation needed, which particularly causes necrosis and healing problems and, hypothetically, ruptures. More than 500 fibroid enucleations have been performed with the described technique and there have been no uterine ruptures during pregnancy or during delivery. Lift-laparoscopy extends organ-preserving operations for fibroid removal of any size according to the skill of the surgeon. Even myomatous uteri with a size of about 1.5 kg can be managed. For morcellation of such huge fibroids, an electrical morcellator should be used; however, small myomas can be morcellated without difficulty with a scalpel or scissors.

LAPAROSCOPIC HYSTERECTOMY

The most difficult problem in hysterectomy is how to divide vessels, especially the uterine artery. Many surgeons therefore perform a laparoscopic assisted vaginal hysterectomy (LAVH) to avoid the risk of hemorrhage from the uterine vessels. Gasless laparoscopy allows plenty of variation for the ligation of vessels. One can apply ligatures around the uterine vessel, and after applying a ligature contralaterally the uterine vessels can be divided. Coagulation using bipolar forceps or other energy sources is also possible in lift (gasless)-laparoscopy. An additional positive effect is that the open trocars allow the evacuation of smoke by simple exsufflation via the insufflation channel of the optic trocar, thus avoiding additionally fogging of the laparoscope. Using the bipolar scissors, coagulation and cutting can be securely performed in one step without carbonization and with less coagulation necrosis. With one-step coagulation and cutting, the laparoscopic procedure becomes very fast as there is no change of instruments. To open the vaginal cuff, one can use a scalpel or bipolar scissors. No special tools need to be inserted to avoid gas leakage after opening the vagina.

ADHESIOLYSIS

Adhesions are an inevitable consequence of surgery and their optimal management and prevention remain unanswered. The magnitude of this problem has been overlooked due to a lack of awareness of their clinical significance. Adhesions cause serious short-term and long-term complications related to bowel obstruction, infertility, and pelvic pain, worsening the quality of life of the patients. This further increases the burden on patients and doctors, and drains the economic resources of the healthcare system. Despite advances in the surgical technique (laparoscopy) and instrumentation (microsurgical instruments), the frequency of adhesion-related complications or disorders (ARD) still remains relatively unchanged. Clinical studies and research clearly reveal that the burden of adhesion-related problems (i.e. de-novo adhesion formation, recurrence, complications, and readmission and re-surgery rates) following laparoscopic gynecologic surgery is unfortunately similar to that found after open surgery. Adhesion surgery has to be based on two most important issues: ● ●

surgical tools and techniques adhesion prevention.

Avoiding carbon dioxide (CO2) insufflation is very important to avoid hypoxemia, dessication of the peritoneal tissue, and acidosis. Already after 5 minutes of ischemia there is a significant production of free radicals that have not enough oxygen to react with. Therefore, free radicals will initiate adhesion formation, starting with cytolysis of these cells and peroxidation of lipids in the cell membrane that lead to an increase in vascular permeability which causes, among other things, also an imbalance in fibrin deposition and fibrin dissolution, producing fibrinous adhesions. Using carbon dioxide gas induces adhesion formation by lowering the level of special molecules that are needed for the healing process, and so carbon dioxide is (for the surgeon) an invisible instrument that causes injury to the peritoneum with the result of adhesion formation. Thus, lift (gasless)-laparoscopy is the ideal tool for laparoscopic adhesiolysis. In addition to special and new bipolar instruments, lift-laparoscopy allows control of hemostasis, which is a condition sine qua non in adhesiolysis surgery to avoid adhesion reformation. Several adhesion-reducing agents (barriers) have been experimented with, but their widespread use is limited by efficacy, cost-effectiveness, safety, and

technical issues. In spite of extensive research involving enormous financial expenditure aimed at the prevention and treatment of adhesions, an ultimate solution has still not been forthcoming to conquer this challenging problem. Clearly, to enhance good and safe medical practice, optimal strategies for management and prevention are needed. SprayGel™ is a new product (Confluent Surgical, Waltham, MA) based on two liquids, which are polyethylene glycol (PEG) and hydrogel. When these two liquids are applied while mixing them in situ, they polymerize within seconds to form a visible, adherent, and conforming hydrogel barrier on the target tissues. The gel remains intact for the next 5–7 days before breakdown by hydrolysis, and eventual clearance through the kidneys. Our long-term utilization of SprayGel™ along with lift-laparoscopy in patients undergoing adhesiolysis in combination with second-look laparoscopy shows excellent results, with a high decrease of adhesion reformation in the second look as well as in long-term follow-up.

Figure 11.16 The distal end of the adhesions are excised under coagulation using bipolar scissors. This step has to be performed with extreme care as the bowel loops are very close to the scissors

ADHESIOLYSIS

Figure 11.17 Here the use of traction by the sponge holder can be well appreciated. The sponge keeps the tissues at a stretch so that the scissors can cut in the correct plane. Bipolar scissors free the adhesions from the anterior abdominal wall

Figure 11.18 The edge of the bowel loop is held with non-traumatic grasper forceps and a suction irrigation cannula is used for separation of the adhesions from the anterior abdominal wall

Figure 11.23 Adequate irrigation is always done with a suction irrigation device to keep the tissue surfaces moist and to look for any bleeding. Using the suction device, any collected blood, blood clots, or tissue debris is removed, as these can be a nidus for adhesion reformation. An intraperitoneal drain is placed and removed after 24 hours

Figure 11.24 Bleeding vessels, if any, are identified and coagulated, and also the bowel surfaces are inspected for any trauma

ADHESIOLYSIS

Figure 11.25 SprayGel ™ is used as an adhesion-prevention barrier agent. The SprayGel ™ apparatus is assembled and connected to the air pump. The SprayGel ™ applicator is inserted into the peritoneal cavity and its tip is inclined slightly for proper application of the SprayGel ™. SprayGel ™ is then sprayed (applied) over the separated raw surfaces to prevent adhesion formation with the help of a sprayer attached to the air pump

Figure 11.26

Figure 11.27 Now SprayGel ™ is applied on the bowel surfaces as well. It takes around 1 or 2 minutes for the gel to set over the tissue surfaces

Figure 11.28 Once the gel is set, intraperitoneal lavage is applied. The bowel is then finally inspected for hemostasis and trauma with the blunt tip of the suction irrigation device. One can see the SprayGel ™ ‘treated and untreated’ bowel loops

Figure 11.31 The serosa of the bowel is seen at second-look laparoscopy. Adequate vascularity and rugosity can also be noted

Figure 11.32 At second-look laparoscopy no scar or fibrotic tissue is noted on the bowel serosa at the site of adhesiolysis. One can note neovascularization in the new peritoneum that has built up under the surface of the SprayGel ™. At the bowel loops the peritoneal healing process is nearly finished
