Preface to the 2nd edition

The hysteroscopic diagnostics and therapy have become a main focus in the clinical and research activities at the Department of Obstetrics and Gynaecology at the University of Greifswald at the beginning of the 1990s, and hundreds of gynaecologists have been trained in hysteroscopy during the traditional Days of Hysteroscopy in Greifswald. As a consequence we decided to pass on this extensive experience and published a Hysteroscopic Guide for Gynaecologists together with Professor Straube in 1996. With this book the idea of Gynaecological Pocket Guides, which shall represent in a short, concise and pictorial way the main areas of our speciality, was born. After more than ten years hysteroscopy has further developed, which led to this 2nd edition containing the latest aspects of diagnostic hysteroscopy and its practical applications. The 2nd edition shall contribute to the further enhancement of diagnostic hysteroscopy in the practices and in hospitals. I would like to thank everyone who supported me in completing the book. I thank Ms. Timm for typing the manuscript, and Ms. Dr. Kowalski and Ms. Dobler from Walter de Gruyter publishing house for their excellent advice and for having responded to all my comments and requests. Cologne, February 2010

1. Introduction

In the last two decades hysteroscopy has been established as a method for the diagnostics and therapy of intrauterine diseases. The scope of indications has permanently increased so that today this method belongs to the standard practices in gynaecology. With the development of thin lenses hysteroscopy is not only feasible in hospitals but for many indications also in the gynaecological practice without anaesthesia. For that reason aspects of the diagnostic hysteroscopy for outpatient treatment are especially considered. For the diagnostics of sterility and bleeding disorders hysteroscopy constitutes only one form of treatment. Therefore in the case studies of this 2nd edition of the Hysteroscopic Guide this method is placed in line with anamnesis, sonography, histology and therapy. The present guide sets out to offer to the gynaecologist a companion for the practical use of hysteroscopy.

2. History

The first hysteroscopy was reported by PANTALEONI in the English journal The Medical Press in 1869. The Frankfurt physician BOZZINI, who in 1804 developed the so-called light conductor, already then talked of the possibility of hysteroscopy. In the next century there were many attempts to establish hysteroscopy as a method for gynaecological diagnostics. Its decisive impetus hysteroscopy owes to LINDEMANN, who succeeded in the 1970s in improving CO2-hysteroscopy as a method. With the possibility of therapeutic hysteroscopies and as a result of numerous technical improvements this method has now found its well-deserved application. Over the last decades the scope of applications of hysteroscopy, especially for the diagnostics of bleeding disorders, has increased by the use of fluid distending media. Thin lenses and sophisticated optical systems facilitate a high picture quality. The development of compact systems for the use in the practices (Telepack) is going to further enhance this method.

3. Indications for diagnostic hysteroscopy

1. bleeding disorders 2. diagnostics and staging of endometrial cancer 3. diagnostic assessment of sonographically suspect endometrial findings 4. sterility/infertility 5. control after intrauterine operations (intrauterine adhesiolyses, septum dissections, curettages following an abortion, curettages post partum or in childbed) 6. control after medical therapy of endometrial hyperplasias 7. lost IUD/IUS

4. Instrumentation and distending medium

1. Compulsory –– hysteroscope (30$ lenses), when indicated with continuous flow sheath –– distending medium –– light source –– (self-holding) specula 2. Optional –– video documentation –– grasping forceps –– probe/Hegar’s dilatators –– small curette for endometrial biopsy Attention: Diagnostic hysteroscopy can be best performed with 30$ lenses.

Instrumentation and distending medium

5

Small curette for target curettage or endometrial biopsy for outpatient diagnostic hysteroscopy. Self-holding specula (available in various sizes).

Attention: Extraction of histological material is possible with this curette without further cervix dilatation. Attention: Self-holding specula are especially recommended for outpatient hysteroscopy because a fixation of the cervix with grasping forceps may be dispensed with in most of the cases.

6


Diagnostic hysteroscope (2 mm-30$ -lenses), with a 2.8-mm-diagnostic sheath and a 3.6-mm-flow sheath with the possibility of continuous flow.

Attention: The continuous flow sheath is especially suited for fresh bleeding ex utero or coagula in utero for the clearing irrigation of the cavum uteri. Attention: A flushing effect may also be reached when the cervix is dilated further (Hegar 8), so that the outflow may be reached via the dilated cervical canal.


7

Bettocchi-hysteroscope with working sheath for semi-rigid instruments (biopsy forceps, grasping forceps, microscissors) and continuous flow sheath, lenses 2 mm, outer diameter: 4.2 mm.

Attention: The small-size instruments are only suited for the biopsy of focal lesions, cutting off of small polyps, IUD-extraction and cutting of intrauterine adhesions grade 1 and 2.

8


Semi-rigid instruments for the Bettocchi-hysteroscope 1. 2. 3. 4. 5. 6.

biopsy- and grasping forceps biopsy spoon forceps punch blunt scissors sharp scissors myoma-fixation instrument

Attention: For the insertion of the working sheath the non-anaesthetized patient may be given a local anaesthetic if necessary. Attention: The tissue gained from biopsy may often be very small, so that a small curette may be used.


9

Diagnostic standard hysteroscope, 4 mm-30$ -lenses and 5.1 mm outer diameter (without continuous flow sheath).

Attention: With patients suffering from cervical stenosis minihysteroscopy is primarily used.

10


Xenon light source with up to 300 W.

Attention: A high-performance light sources enhances diagnostic reliability.


11

HAMOU- microhysteroflator for CO2-hysteroscopy

Left: Digital CO2-pressure indication (mmHg) Right: Digital CO2-flow indication (ml/min).

Attention: The pressure in CO2-insufflators is limited to 200 mmHg. Attention: CO2-insufflators for laparoscopy (Laparomat) must not be used for hysteroscopy.

12


Pressure-cuff for diagnostic hysteroscopy with a fluid distending medium for 1-l-fluid (usually isotonic saline solution). Pressure on the cuff is in most of the cases adjusted to 150 mmHg (up to at most 200 mmHg).

Attention: With a more difficult passage through the cervical canal a short-term increase in pressure is recommended because it facilitates the opening of the cervical canal and the following passage.


13

Videocamera Image 1 (digital 3-chip-camera) with pendular head and Image 1 (standard head) with control gear.

Advantage: The pendular camera remains centred even when moved, which facilitates orientation.

14


Telepack-system with connected camera head (Telekam) and light cable.

Advantages of the Telepack-system: –– mobile use –– space-saving –– multi-functional (light source, screen, camera, documentation – all in one device) –– allows for video and photo documentation –– cost-effective (low costs)

Table 1: Comparison of CO2 -hysteroscopy and hysteroscopy with a fluid distending medium

1. picture 2. technical complexity 3. usage 4. risk of dissemination (infection, tumour cells) 5. diagnostics of bleeding disorders 6. diagnostics of sterility

CO2-hysteroscopy

hysteroscopy with fluid medium

very clear higher some experience necessary very low

clear low easy

limited (with current bleeding) very good

slightly higher very good good

Attention: Especially for the diagnostics of bleeding disorders hysteroscopy with a fluid distending medium should be preferred. Attention: One advantage of the hysteroscopy with a fluid distending medium is that a follow-up control of the cavity after mechanical removal of polyps or dilatation/curettage is possible.

16

Hysteroscopic finding

Hysteroscopic finding: Passage of the cervical canal with CO2-hysteroscopy. Further forward movement towards the gas bubbles.


17

Hysteroscopic finding: Passage of the cervical canal with hysteroscopy with a fluid medium. Clear view of the cervical canal with further forward movement of the hysteroscope towards the cavity.

18


Hysteroscopic finding after the setting up of the hysteroscope on the external os of the cervical canal.

Attention: Through the supply of the distending medium the cervical canal unfolds and the passage with the hysteroscope becomes possible.


19

Hysteroscopic finding (CO2 as distending medium): Regular cavity with atrophic endometrium.

Panoramic hysteroscopy: Fundus, posterior wall and tubal cornua clearly visible on both sides. Disadvantage: Gas bubbles obstruct the assessment of the posterior wall of the cavity.

20

Regular cavity with cervical stenosis

52-year-old patient 1. Clinical diagnosis 2. Anamnesis 3. Sonography

cervical stenosis cervical stenosis, cytological swab not possible endometrium thickness: 6 mm

4. Hysteroscopy

regular cavity after dilatation of the cervix

5. Therapy

dilatation of the cervix, dilatation/ curettage

6. Histology

atrophic endometrium, cervix without findings


21

Hysteroscopic finding: Regular cavity with normal endometrium. Hysteroscopy with a fluid distending medium makes assessment difficult by air bubbles on the anterior wall.

Attention: Air bubbles in the cavity can be avoided by paying attention to an empty input tube for the fluid distending medium during hysteroscopy.

5. Examination procedure and techniques

Examination procedure for the diagnostic hysteroscopy –– palpation/sonography –– vaginal disinfection –– adjustment of specula –– (grasping forceps) –– setting up of hysteroscope (Attention: There must be no air in the input tube!) –– monitored passage through the cervical canal –– panoramic hysteroscopy –– assessment of the fundus and the tubal ostia –– assessment of the cavity walls –– assessment of the cervical canal when removing the hysteroscope –– biopsy (eye-directed/target biopsy) or dilatation/curettage Attention: For hysteroscopy the tubal ostia are the major points of orientation (landmarks) in the uterine cavity. Technique Lesions of the endometrium are to be avoided. Therefore mind the following principle: Attention: The hysteroscope is always the first instrument in the cervical canal. Attention: Probing of the uterine cavity and dilatation of the cervical canal with Hegar’s dilators should, if possible, only be performed after a hysteroscopic inspection of the original cavity. Exception: cervical stenosis

Examination procedure and techniques

23

Problematic situations in diagnostic hysteroscopy 1. nullipara 2. craurosis fornicis 3. state after conisation solution: –– use of a thinner hysteroscope (2-mm-hysteroscope) –– local application of prostaglandins disadvantages of the local application of prostaglandins: –– side effects (gastrointestinal) –– bleedings may obstruct vision –– danger of via falsa because of softening-up of the whole cervix –– additional costs Attention: The local application of prostaglandins is only necessary in rare cases. With a cervical stenosis the use of minihysteroscopes is the prime choice.

24


Hysteroscopic finding: With further forward movement of the hysteroscope a cervical stenosis becomes visible. In this case passage is only possible after dilatation up to Hegar 5.

Attention: Cervical stenosis (mostly on the ostium cervicis internum) can be hysteroscopically exactly verified and thus be directly dilated.

Regular cavity (minihysteroscopy, cervical stenosis)

25

26



cervical stenosis, lower abdominal pain cervical stenosis, cytological swab not possible, occasional abdominal pain endometrium thickness: 3 mm (secretory congestion, mucous cervix)

4. Hysteroscopy

mucous cervix cervical stenosis regular cavity, ostia free

5. Therapy

dilatation of the cervix, dilatation/ curettage atrophic endometrium, cervix without findings

6. Histology

Optimal time for examination 1. in sterile and infertile patients – immediately post menstruationem 2. in perimenopausal patients – with bleeding disorders possibly post menstruationem 3. in postmenopausal patients – as soon as possible after the bleeding Local anaesthesia Indication 1. cervical stenosis 2. craurosis fornicis 3. nullipara 4. necessity of use of a 7-mm-hysteroscope with working sheath


27

Local anaesthesia Paracervical block

depot in the subvaginal epithelium for grasping forceps 5 ml of a local anaesthetic paracervically

Attention: Before injection always aspiration to avoid intravascular injection. Attention: Wait for the effect of local anaesthesia (3–5 minutes) before beginning with hysteroscopy or further manipulations. Attention: With the development of thin hysteroscopes local anaesthesia with outpatient hysteroscopies has become necessary only in rare cases. (Patients may suffer from more pain from the injection than from the passage of the cervical canal with the minihysteroscope.)

28


Permitted movements of the hysteroscope with a patient without anaesthesia 1. forward and backward movement 2. rotation with use of 30$ -angle lenses


29

Attention: With the help of these two movements 95 % of all uterine cavities can be completely assessed.

30


correct

forbidden

Attention: Avoid horizontal and vertical movements of the hysteroscope because that may be painful for the patient without anaesthesia.

Documentation of the findings

31

Description of a hysteroscopic finding: 1. cervix: width, state of the mucous membrane, pathology (e.g. cervical polyp) 2. corpus: size (length, width, symmetry) ( endometrium thickness (test with sheath of hysteroscope) endometrium sliding test ( vascularisation ( free-running vessels) ( local change (polyp, hyperplasia) ( myomas (submucous/intramural) – grade scale ( ostia open/obstructed (landmarks of hysteroscopy) Attention: Especially with pathological changes hysteroscopic findings should be precisely described. Attention: Myomas, uterine malformations and intrauterine adhesions should be classified according to the standard grades of ESGE.

32

Regulary cavity – documentation

6. Histology

Attention: The photo documentation should consist of at least three pictures (both ostia, panoramic view of the cavity). With pathological findings a systematic documentation and corresponding description of the findings are necessary.

6. Distinctive features of hysteroscopy in the gynaecologist’s practice

The performance of hysteroscopy without anaesthesia in a gynaecologist’s practice has to fulfil certain requirements with regard to: ( the patient ( the examiner ( the equipment The examination procedure is similar to the one described on page 22. Distinctive features 1. use of self-holding specula 2. no grasping with the forceps 3. use of as thin as possible hysteroscopes 4. mostly use of endometrium biopsy 5. patient can watch the findings on the monitor screen The outpatient hysteroscopy has many advantages: 1. For the patient ( no anaesthesia ( outpatient treatment (in the practice) ( direct information about medical findings 2. For the gynaecologist ( direct treatment of the patient ( additional offer ( relatively low costs

Attention: With sonographically verified intracavitary findings (polyp, myoma) minihysteroscopy should be used only after careful consideration to avoid double interventions.

7. Hysteroscopy in the diagnostics of sterility and infertility

Indications for diagnostic hysteroscopy in the diagnostics of sterility 1. 2. 3. 4.

primary sterility secondary sterility infertility (habitual abortions) post-abortion-hysteroscopy Diagnostic hysteroscopy in patients with desire of pregnancy about 8 to 12 weeks after abortion curettage for the early diagnostics of intrauterine causes of abortions and adhesions 5. control hysteroscopy after septum dissections or intrauterine adhesiolyses Attention: For the diagnostics of any sterility and infertility hysteroscopy is a standard method and therefore essential.

HSG versus hysteroscopy in the diagnostics of sterility Table 2: HSG versus hysteroscopy HSG–findings

hysteroscopy

( round defect of contrast medium

( polyp ( myoma ( air bubbles (hysteroscopically normal findings)

( median, clean defect of contrast medium

( uterus septus –– uterus bicornis

( blurred defect of contrast medium

( intrauterine adhesions

Attention: Intrauterine adhesions of smaller grades of extent cannot be safely detected by hysterosalpingography.

Attention: Hysterosalpingography lost its importance by the increasing use of endoscopic diagnostic methods (hysteroscopy, laparoscopy).

38


Hysterosalpingography with patient suffering from habitual abortions Diagnosis: uterus septus/bicornis – diagnostic assessment by hysteroscopy and laparoscopy. Final diagnosis: uterus subseptus.

Sonography versus hysteroscopy in the diagnostics of sterility ( Sonographically, intrauterine adhesions can be presumed only in a third of the cases. Sonographically diagnosed endometrial defects are a sign of more severe adhesions (ESGE grade extent III and IV) (see page 58). ( Slight uterus malformations (septum smaller than 2 cm) are often missed by sonography (in about 30 % of the cases). Attention: Sonography for the detection of uterus malformations should be performed immediately before menstruation (thicker endometrium). Then in most of the cases two endometrial areas can be visualized.

ESGE classification of intrauterine adhesions

Table 3: Intrauterine adhesions – classification of the European Society of Gynaecological Endoscopy (ESGE) grade I:

thin, filmy adhesions ( easily ruptured by sheath of the hysteroscope ( regular cornual areas

grade II:

singular firm adhesions ( in different areas of the cavity ( connect uterine walls, but both tubal ostia are visible ( cannot be ruptured by sheath of the hysteroscope

grade II A:

occluding adhesions only in the area of the internal cervical os, upper uterine cavity is regular

grade III:

multiple firm adhesions ( in several areas ( unilateral obliteration of the cornual area

grade III A:

extensive scarring of the uterine cavity with amenorrhea or pronounced hypomenorrhea

grade III B:

combination of III and III A

grade IV:

extensive firm adhesions with agglutination of the uterine walls – both tubal ostia are occluded

Attention: A classification according to the grade extent is primarily necessary because of its therapeutic and prognostic consequences.

hypermenorrhea, menorrhagia metrorrhagia recurrent additional bleedings postmenopausal bleedings bleeding disorders under oral contraception bleeding disorders under hormone replacement therapy bleeding disorders under Tamoxifen bleeding disorders with inserted IUD/IUS

Hysteroscopy with bleeding disorders

67

Hysteroscopic finding: With bleeding disorders the typical first hysteroscopic view which gets clearer after influx of the distending medium. If not, check or increase the influx of the distending medium.

Attention: With more serious bleeding a continuous flow hysteroscopic sheath should be used or the cervix should be further dilated. Potential sources of unclear view: 1. lack of flow 2. lack of pressure on the cuff 3. bend in the inflow sheath 4. closed flow-tap on hysteroscope 5. instruments are not correctly assembled 6. empty infusion 7. lenses are blurred by coagula 8. defective lenses or light source

68

Hysteroscopy with bleeding disorders

Sonography versus hysteroscopy in the diagnostics of bleeding disorders A differential diagnosis of polyps and myomas is sonographically not possible with certainty. A localization of the myoma (intramural or submucous) is not possible by sonography with precision. Hyperplastic endometrial structures diagnosed by sonography in postmenopausal women are hysteroscopically in 30 to 50 % of the cases corpus polyps. The clinical diagnosis and vaginal sonography provide the background to a hysteroscopic-histological diagnostic assessment.

By sliding the hysteroscopic sheath in the hyperplastic endometrium a difference in level between endometrium and myometrium can be shown. This allows for a better assessment of the extent of the hyperplasia. Attention: With high intrauterine pressure and evenly distributed endometrial hyperplasia the endometrium is often wrongly classified as atrophic or flat without the endometrium sliding test.

96

Corpus polyps

Corpus polyps 1. Corpus polyps constitute one the most frequent causes of bleedings (especially in the perimenopause). 2. With a dilatation/curettage without hysteroscopy polyps are often not or incompletely removed. 3. Hysteroscopy makes the diagnostics of polyps possible, and the complete removal can be checked during the intervention (control hysteroscopy). 4. With the complete removal of the polyps (by target curettage, grasping forceps or resection) most of the bleeding disorders are successfully treated. 5. The removed polyps must be carefully examined by histology.

106

Corpus carcinoma

Corpus carcinoma 1. The incidence of corpus carcinomas rises in line with the increasing age of the patients. 2. With estrogen-dependent carcinomas sonography (endometrium thickness >9 mm) is in most of the cases the method of diagnostics, whereas with de novo-carcinomas clinical signs (bleeding) constitute the only initial symptom. 3. Especially with corpus carcinomas hysteroscopy should be extended to the cervix, too, to correct a too high staging (extension to the cervix – stage 2) with the dilatation/curettage. 4. The potential transmission of tumour cells by hysteroscopy has been disproved by some studies, especially since in most of the cases a simultaneous operative therapy of the corpus carcinoma is performed.

Bleeding disorders under hormone replacement therapy

Bleeding disorders under hormone replacement therapy 1. Bleeding disorders under hormone replacement therapy must be adequately diagnosed but do not require more invasive diagnostics than bleeding disorders without HRT because the histological findings do not show any differences. 2. The invasive diagnostics of bleeding disorders under HRT reduces the subsequent compliance. 3. Minihysteroscopy without anaesthesia in the practice is especially suited for the diagnostics of bleeding disorders under HRT because the rate of compliance for HRT remains unaffected.

Endometrium and Tamoxifen

Endometrium and Tamoxifen 1. Endometrial hyperplasias under Tamoxifen develop dependent on the dosage and the duration of medication. 2. Bleeding disorders under Tamoxifen require an intensive diagnostic assessment. 3. Endometrial hyperplasias under Tamoxifen do not respond to a progestagen therapy (reason: stromal hyperplasia). 4. With asymptomatic patients undergoing Tamoxifen therapy an annual sonographic check-up of the endometrium is recommended. 5. When the endometrium shows a tendency to grow (endometrium thickness >12 mm) a diagnostic assessment is necessary. 6. Since by a simple dilatation/curettage endometrium for histological examination may often not be extracted, a segmental endometrial resection (by resectoscope) must be performed, if necessary.

10. Hysteroscopy and lost IUD/IUS

1. Lost IUD is one of the classic indications for a hysteroscopy. 2. At first the intrauterine evidence of the IUD/IUS should be provided by sonography. 3. The most frequent indication results from the tearing off of the IUD- thread when trying to extract the IUD. 4. The IUD can be extracted after the hysteroscopic evidence of the IUD and by using a small grasping forceps. Alternatively, a grasping forceps may be introduced through the working sheath and the IUD/IUS can then be extracted with the removal of the whole instrument.

Bleeding disorders with dislocated IUS (MIRENA)

139


3. Sonography

bleeding disorders with MIRENA in situ and large uterus (probe length ¼ 13.0 cm) for 6 months recurrent permanent bleedings with MIRENA in situ with adipose patient uterus clearly hyperplastic without insulated myomas uterus hyperplasia, MIRENA in the large cavity clearly dislocated

4. Hysteroscopy

MIRENA transversely located in the uterine cavity, endometrial hyperplasia

5. Therapy

extraction of MIRENA dilatation/curettage new insertion of MIRENA with hysteroscopic view (at urgent request of the patient, who refuses a further operative therapy; oral progestagens are contraindicated) simple hyperplasia

6. Histology

11. Special cases

Placental residuals 1. After some time placental residuals can become necrotic or calcify. 2. With placental disorders (placenta accreta or increta) the removal without exact localisation can be difficult. 3. In these cases hysteroscopic diagnostics and the targeted removal (if necessary, even operatively) is the treatment of choice. 4. With very large solid residuals several sessions may be necessary. Adhesions after IUS Intrauterine adhesions after IUS are extremely rare and can only be explained by local inflammation of the endometrium. Endometritis Bleeding disorders are only rarely caused by endometritis, which is in most of the cases an incidental finding.

Placental residuals after missed abortion

3. Sonography

sonographically suspect placental residuals and persistent hCG-levels missed abortion 13th week of pregnancy abortion curettage, after that sonographically suspected placental residuals 3 times hysteroscopy and dilatation/curettage with postoperatively persistent sonographic findings (performed externally), followed by 3 cycles of Methotrexate-therapy (because of increased hCG-levels) clearly visible, partially calcified placental residual of 2.0 ' 2.0 cm

4. Hysteroscopy

left tubal cornua and lateral wall partially calcified and necrotic placental residual

5. Therapy

operative hysteroscopy: resection of the placental residuals necrotic placental residuals, no malignancy

6. Histology

142

Placental residuals


3. Sonography

placental residuals with placenta accreta spontaneous delivery 3 months ago, followed by a persistent large solid intracavitary finding, recurrent bleedings, 3 times dilatations/curettages without success (performed externally) solid intracavitary vascularised finding, size: 70 ' 60 mm, occupying the entire cavity

4. Hysteroscopy

large, partially necrotic placental residuals occupying the entire cavity

5. Therapy

resection of the placenta by bipolar hysteroscopy in two sessions necrotic placental residuals (240 g)

6. Histology

Intrauterine adhesions grade 3 after MIRENA

143


3. Sonography

secondary amenorrhea after extraction of MIRENA 9 months ago for 5 years MIRENA as method of contraception, after extraction secondary amenorrhea, hormonal status: without pathological findings, no induction of bleedings possible in spite of estrogen substitution, suspicion of intrauterine adhesions no endometrium visible

4. Hysteroscopy

intrauterine adhesions grade 3, right lateral wall

5. Therapy

intrauterine adhesiolysis

144

Endometritis

Endometritis

1. Indication

postmenopausal bleeding

2. Hysteroscopy

entire cavity reddened, endometrium touch-sensitive and bleeds easily (see posterior wall)

3. Diagnosis

endometritis

Attention: If the entire cavity is reddened, there is a strong suspicion of endometritis.

12. Complications

1. 2. 3. 4. 5. 6.

endometritis/adnexitis 0.01 % dysregulation of circulation 3 to 5 % (without anaesthesia) via falsa (cervical canal) 2 % uterus perforation 0.1 % embolism (singular cases) dissemination of tumour cells

Attention: With all safety aspects considered the total rate of complications is lower than 1 per mill. Attention: A dissemination of tumour cells is excluded by CO2-hysteroscopy. Attention: A dissemination of tumour cells by hysteroscopy with a fluid distending medium is very unlikely.

Via falsa


recurrent hypermenorrhea and dysmenorrhea for 3 years increasing hyper- and dysmenorrhea, finished family planning suspicion of adenomyosis (hyperplastic myometrium) endometrium thickness: 8 mm (post menstruationem)

4. Hysteroscopy

Intrauterine adhesions grade 3 (perforation)


3. Sonography

secondary uterine amenorrhea spontaneous delivery 9 months ago with curettage post partum because of placental residuals (positive), after that secondary amenorrhea endometrium only partially visible, no hematometra

4. Hysteroscopy

cervical stenosis intrauterine adhesions grade 3 (right half of the cavity completely obstructed) slight perforation of the fundus

5. Therapy

dilatation of the cervix termination of the operation antibiotic prophylaxis ! hysteroscopic adhesiolysis 4 months after healing up of the perforation – without problems none
