[CAMIC Recommendations for Surgical Laparoscopy in Non-Obstetric Indications during Pregnancy]. / CAMIC-Empfehlungen zur chirurgischen Laparoskopie aus nicht geburtshilflicher Indikation während der Schwangerschaft.

In the operative surgical primary care, the laparoscopic surgical technique has firmly established itself in recent years. Meanwhile, in the normal population over 90 % of all cholecystectomies and over 80 % of all appendectomies are performed in a minimally invasive manner. The proven benefits of the laparoscopic surgical technique, compared with conventional open surgery, are a comparatively rapid early postoperative recovery with early resumption of the general physical and occupational activity. As these benefits are equally applicable for necessary interventions during pregnancy, in recent years laparoscopy has become the preferred treatment for non-obstetric indications in the gravid patient. Overall, it can be assumed that such interventions have to be performed in approximately 2 % of all pregnant patients. Numerous studies have proven here that the use of laparoscopic techniques, in particular for the expectant mother, is safe and not associated with an increased risk. On the other hand, the current pregnancy makes necessary an adapted approach to the solution of surgical problems to ensure the protection of the unborn child. On the basis of currently available data situation, recommendations are formulated which can be used as a decision-making support for a variety of clinical situations.

Gynaecological endoscopic evaluation of 4% icodextrin solution: a European, multicentre, double-blind, randomized study of the efficacy and safety in the reduction of de novo adhesions after laparoscopic gynaecological surgery.

BACKGROUND: Gynaecological laparoscopic surgery outcomes can be compromised by the formation of de novo adhesions. This randomized, double-blind study was designed to assess the efficacy and safety of 4% icodextrin solution (Adept(®)) in the reduction of de novo adhesion incidence compared to lactated Ringer's solution (LRS). METHODS: Patients undergoing laparoscopic surgery for removal of myomas or endometriotic cysts were treated with randomized solution as an intra-operative irrigant and 1l post-operative instillate. De novo adhesion incidence (number of sites with adhesions), severity and extent were independently scored at a second-look procedure and the efficacy of the two solutions compared. The effect of surgical covariates on adhesion formation was also investigated. Initial exploratory analysis of individual anatomical sites of clinical importance was progressed. RESULTS Of 498 patients randomized, 330 were evaluable (160 LRS--75% myomectomy/25% endometriotic cysts; 170 Adept--79% myomectomy/21% endometriotic cysts). At study completion, 76.2% LRS and 77.6% Adept had ≥ 1 de novo adhesion. The mean (SD) number of de novo adhesions was 2.58 (2.11) for Adept and 2.58 (2.38) for LRS. The treatment effect difference was not significant (P = 0.909). Assessment of surgical covariates identified significant influences on the mean number of de novo adhesions regardless of treatment, including surgery duration (P = 0.048), blood loss in myomectomy patients (P = 0.019), length of uterine incision in myomectomy patients (P < 0.001) and number of suture knots (P < 0.001). There were 15 adverse events considered treatment-related in the LRS patients (7.2%) and 18 in the Adept group (8.3%). Of 17 reported serious adverse events (9 LRS; 8 Adept) none were considered treatment-related. CONCLUSIONS: The study confirmed the safety of Adept in laparoscopic surgery. The proportion of patients with de novo adhesion formation was considerably higher than previous literature suggested. Overall there was no evidence of a clinical effect but various surgical covariates including surgery duration, blood loss, number and size of incisions, suturing and number of knots were found to influence de novo adhesion formation. The study provides direction for future research into adhesion reduction strategies in site specific surgery.

[Clinical 3-year follow-up of uterine fibroid embolization]. / Klinische 3-Jahres-Ergebnisse nach Uterusmyomembolisation.

PURPOSE: The purpose of this study was to evaluate the clinical long-term success of uterine artery embolization (UAE) in patients with symptomatic fibroids using spherical particles (Embosphere). MATERIALS AND METHODS: 34 consecutive patients treated with UAE were initially enrolled in the study which had the following study goals 1) 1-year follow-up MRI evaluation of the fibroid behavior and 2) clinical long-term success due to standardized assessment of the main fibroid-related symptoms (hypermenorrhoea, dysmenorrhoea and dysuria) of the patients' individual overall health status and their therapy satisfaction at 1-year, 2- year and 3-year intervals after UAE. RESULTS: Technical success was achieved in all procedures. Four patients had to be excluded from the long-term evaluation schedule: one because of a hysterectomy due to bleeding after 6 weeks, 3 patients were not available for the designated minimum follow-up interval. The preinterventional severe hypermenorrhoea (n = 27) with a score of 4.4 +/- 0.7 (5 = extreme menstrual bleeding) decreased after one year to 2.1 +/- 0.5 (p = 0.0001), after two years to 1.7 +/- 0.5 (p = 0.0042) and after three years to 1.3 +/- 0.6 (p = 0.0001). The preinterventional dysmenorrhoea (n = 15) with a score of 3.1 +/- 1.5 (3 = distinctly increased dysmenorrhoea) decreased after one year to 1.1 +/- 0.3 (p = 0.0001), after two years to 1.2 +/- 0.2 and after three years to 1.2 +/- 0.4 (p = 0.148). The pretreatment dysuria (n = 12) with a preinterventional score of 3.1 +/- 1.5 (3 = distinctly increased dysuria) decreased after one year to 1.1 +/- 0.3 (p = 0.0069) and remained after two years at 1.1 +/- 0.2 and after three years at 1.2 +/- 0.4 (p = 0.905). The initial overall health status was 54.7 +/- 20.1 (maximal value 100). After one year it rised to 90.5 +/- 15.4 (p = 0.0001), was 91.8 +/- 5.6 after two years and was 91.3 +/- 8.5 (p = 0.8578) after three years. The satisfaction with the therapy was 2.9 +/- 0.2 after one year, 2.6 +/- 0.3 after two years and 2.7 +/- 0.5 (3 = extremely satisfied) after three years. We observed 12 minor and 3 major complications (one hysterectomy, one fibroid expulsion associated with a short bleeding episode and one transient amenorrhoea for three months). All patients benefited clinically from the procedure and a clinical benefit was achieved in all cases. CONCLUSION: Under controlled study conditions, flow-guided UAE with spherical embolization particles achieves high clinical success for all relevant clinical symptoms without negative changes during follow-up after at least 3 years. Accordingly, patient therapy satisfaction remained extraordinarily high even 3 years after UAE.

Expectations for Endoscopic Training During Gynaecological Specialty Training - Results of a Germany-wide Survey.

Question: Endoscopy is an integral part of surgical gynaecology and is playing an increasingly important role in ensuring adequate gynaecological training in the context of specialty training in general. At present, little is known about the expectations and notions of young junior doctors with respect to endoscopic training. For this reason, junior doctors throughout Germany were surveyed on this topic and asked to share their opinions. Methods: Using an anonymized standardized survey, the following information was elicited: importance of endoscopic training, willingness to take courses, expectations for instructors and the hospital, ideas about the number of required operations, both as a surgical assistant and as a surgeon, as well as satisfaction with the current status of training. The questionnaires were sent via the Young Forum (Junges Forum) of the German Society of Gynaecology and Obstetrics (DGGG) and the newsletter of the Working Group for Gynaecological Endoscopy (AGE). Results: The evaluation of the study was based on 109 completed questionnaires. The resident junior doctors were 31 years old on average and were in their third to fourth year of their specialty training on average. The majority of the participants (87 %) considered the learning of endoscopic techniques to be very important and advocated regular participation in endoscopy training courses. Among the participants, 48 % were prepared to invest up to €1500 of their own funds to attend courses up to twice a year during the entire specialty training period. The expectations of the instructors and institutions focused on technical expertise, the willingness and time for teaching and on the number and range of surgical procedures, followed by being granted leave for the courses and having costs covered for the courses. Thirty-eight per cent stated that their expectations had been completely or mostly met and 62 % said they had been met in part or inadequately. Eighty-three per cent of the respondents reported that they would change specialty training institutions in order to achieve their own goals in the context of specialty training. Conclusions: This study presents data for the first time on the satisfaction of young junior doctors and their expectations for endoscopic specialty training. The residents exhibited a high level of interest in endoscopy and a high level of willingness to actively shape the specialty training, including course participation. However, there appears to be a great deal of room for improvement for endoscopic specialty training, independent of the current training institution, training year or sex of the junior doctors.

Indications and Route of Hysterectomy for Benign Diseases. Guideline of the DGGG, OEGGG and SGGG (S3 Level, AWMF Registry No. 015/070, April 2015)

Background: Official guideline "indications and methods of hysterectomy" to assign indications for the different methods published and coordinated by the German Society of Gynecology and Obstetrics (DGGG), the Austrian Society of Gynecology and Obstetrics (OEGGG) and the Swiss Society of Gynecology and Obstetrics (SGGG). Besides vaginal and abdominal hysterectomy, three additional techniques have been implemented due to the introduction of laparoscopy. Organ-sparing alternatives were also integrated. Methods: The guideline group consisted of 26 experts from Germany, Austria and Switzerland. Recommendations were developed using a structured consensus process and independent moderation. A systematic literature search and quality appraisal of benefits and harms of the therapeutic alternatives for symptomatic fibroids, dysfunctional bleeding and adenomyosis was done through MEDLINE up to 6/2014 focusing on systematic reviews and meta-analysis. Results: All types of hysterectomy led in studies to high rates of patient satisfaction. If possible, vaginal instead of abdominal hysterectomy should preferably be done. If a vaginal hysterectomy is not feasible, the possibility of a laparoscopic hysterectomy should be considered. An abdominal hysterectomy should only be done with a special indication. Organ-sparing interventions also led to high patient satisfaction rates, but contain the risk of symptom recurrence. Conclusion: As an aim, patients should be enabled to choose that therapeutic intervention for their benign disease of the uterus that convenes best to them and their personal life situation.

Surgical Methods for the Treatment of Uterine Fibroids - Risk of Uterine Sarcoma and Problems of Morcellation: Position Paper of the DGGG.

The appropriate surgical technique to treat patients with uterine fibroids is still a matter of debate as is the potential risk of incorrect treatment if histological examination detects a uterine sarcoma instead of uterine fibroids. The published epidemiology for uterine sarcoma is set against the incidence of accidental findings during surgery for uterine fibroids. International comments on this topic are discussed and are incorporated into the assessment by the German Society for Gynecology and Obstetrics (DGGG). The ICD-O-3 version of 2003 was used for the anatomical and topographical coding of uterine sarcomas, and the "Operations- und Prozedurenschlüssel" (OPS) 2014, the German standard for process codes and interventions, was used to determine surgical extirpation methods. Categorical qualifiers were defined to analyze the data provided by the Robert Koch Institute (RKI), the German Federal Bureau of Statistics (DESTATIS; Hospital and Causes of Death Statistics), the population-based Cancer Register of Bavaria. A systematic search was done of the MEDLINE database and the Cochrane collaboration, covering the period from 1966 until November 2014. The incidence of uterine sarcoma and uterine fibroids in uterine surgery was compared to the literature and with the different registries. The incidence of uterine sarcoma in 2010, standardized for age, was 1.53 for Bavaria, or 1.30 for every 100 000 women, respectively, averaged for the years 2002-2011, and 1.30 for every 100 000 women in Germany. The mean incidence collated from various surveys was 2.02 for every 100 000 women (0.35-7.02; standard deviation 2.01). The numbers of inpatient surgical procedures such as myoma enucleation, morcellation, hysterectomy or cervical stump removal to treat the indication "uterine myoma" have steadily declined in Germany across all age groups (an absolute decrease of 17 % in 2012 compared to 2007). There has been a shift in the preferred method of surgical access from an abdominal/vaginal approach to endoscopic or endoscopically assisted procedures to treat uterine fibroids, with the use of morcellation increasing by almost 11 000 coded procedures in 2012. Based on international statements (AAGL, ACOG, ESGE, FDA, SGO) on the risk of uterine sarcoma as an coincidental finding during uterine fibroid surgery and the associated risk of a deterioration of prognosis (in the case of morcellation procedures), this overview presents the opinion of the DGGG in the form of four Statements, five Recommendation and four Demands.

Intraluminal ultrasound imaging of the fallopian tube wall: results of standardized in vitro investigations of pig and human tubal specimens.

OBJECTIVE: To investigate to what extent anatomic structures of the tubal wall can be identified reproducibly and whether altered areas can be detected and delimited by intraluminal ultrasound. DESIGN: Standardized in vitro experiment with descriptive evaluation of findings, comparative analysis of apparative and morphologic data, and determination of interobserver variability (video documentation, blinded reviewer). SETTING: Department of Gynecology and Obstetrics, University of Heidelberg, Germany. SPECIMEN(S): Seventy-two human and pig fallopian tubes. INTERVENTION(S): Catheterization with a 2.9F or 3.2F ultrasound catheter and sonographic depiction of the fallopian tube, with either simultaneous manual and sonographic wall-thickness measurement or coagulation of the tubal wall. MAIN OUTCOME MEASURE(S): A correlation coefficient of r = 0.76 for manual and sonographic tubal wall measurements and K = 0.88 (with 95% confidence interval of 0.74-1.0) for interobserver variability in recognizing coagulated areas. RESULT(S): Tubal wall anatomy and artificially altered (coagulated) areas were displayed reproducibly with intraluminal ultrasound, thus giving a characteristic, recognizable pattern of the tubal wall. CONCLUSION(S): These in vitro experiments provide evidence that intraluminal ultrasound may expand the current diagnostic possibilities in cases of tubal pathology, providing nonsurgical access to the tubal wall.

[Uterine fibroid embolization with spheric micro-particles using flow guiding: safety, technical success and clinical results]. / Uterusmyomembolisation mit sphärischen Mikropartikeln unter Flusssteuerung: Sicherheit, technischer Erfolg und klinische Ergebnisse.

PURPOSE: To evaluate safety and mid term efficacy (> or = 1 year follow-up) of uterine fibroid embolization (UFE) using spherical particles (Embosphere) in a study applying criteria identical to those submitted to the FDA for initial material approval. MATERIALS AND METHODS: Twenty of the first 26 consecutive patients referred for potential UFE were enrolled in the study. Pre-interventional MRI was used to assess morphologic contraindication to UFE. The embolization procedures were performed from a unilateral femoral approach using 4F selective catheters in straight vessels, > 2 mm in diameter, and micro-catheters in smaller and tortuous arteries. The endpoint of the "flow guided" embolization was defined by reaching the angiographic "pruned tree" appearance and sluggish flow in the main stem of the uterine artery. Assessment of morphologic mid term success was done by MRI 10 days, 3 months, 6 months, 9 months and 1 year after UFE. The clinical mid term success was assessed by having questionnaires completed for menstrual bleeding, retention of clinical (symptomatic) benefit and quality of life. RESULTS: Technical success was 100 %, with 8 minor (2 post-interventional collapses, 2 hematomas, 4 relevant post-embolizations syndromes, 1 spontaneous expulsion of a submucous myoma) and 3 major complications (1 hysterectomy because of vaginal bleeding for 5 weeks, 1 transient amenorrhea and 1 spontaneous expulsion of myoma with transient bleeding requiring admission). In 17 of 19 patients, MRI showed total fibroid devascularization throughout the entire follow-up. The average shrinkage of the dominant fibroid was 71.3 % at one year. The menstrual bleeding record in the cohort group fell from an average of 501.6 before treatment to 76.2 points at one year. At the same time, the clinical symptoms significantly improved. The patient satisfaction with the applied therapy was > 95 % at 1 year. One patient with residual fibroid perfusion underwent a second procedure, which achieved complete devascularization and adequate clinical success at one year. The second patient with incomplete devascularization had a persistent clinical benefit. CONCLUSION: Under controlled study conditions, flow guided UFE with spherical particles achieves high overall success and patient satisfaction. MRI provides exact morphologic description of the fibroid for the initial evaluation and for post-procedural follow-up.

Identification and quantitation of cocaine and its metabolites, benzoylecgonine and ecgonine methyl ester, in hair of Bolivian coca chewers by gas chromatography/mass spectrometry.

Twenty hair samples obtained from Bolivian mine workers who chewed 3-8 g of coca leaves daily for several years were analyzed for cocaine and its main metabolites, benzoylecgonine (BZE) and ecgonine methyl ester (EME). A new method was developed for the detection and quantitation of cocaine and its metabolites, BZE and EME, from hair in a single procedure. The hair samples were washed, cut into 56 segments (2-cm length), pulverized, and incubated with phosphate buffer and the enzyme beta-glucuronidase-arylsulfatase. After solid phase extraction and derivatization with pentafluoropropionic anhydride/pentafluoropropanol, the drugs were identified and measured by gas chromatography/mass spectrometry (GC/MS) using deuterated cocaine, BZE, and EME as internal standards. The method is reproducible (cocaine, CV = 8%; BZE, CV = 14%) and the detection limit for cocaine and BZE was 0.1 ng/mg, for EME 1 ng/mg. In the different hair segments, cocaine was found to be present in concentrations between 1.4 to 50.6 ng/mg, benzoylecgonine from 0.4 to 17.6 ng/mg, and ecgonine methyl ester traces below the calibration curve of approximately 12.9 ng/mg. In 95% of the cases cocaine exceeded BZE and EME in concentration.

Laser palliation of locoregional recurrences of breast cancer.

The paper reports on the use of carbon dioxide and Nd:YAG lasers for palliation of locoregional breast cancer recurrences. On the basis of three case reports, pros and cons of laser assisted treatment of loco-regionally recurrent breast cancer are discussed. A carbon dioxide--Nd:YAG combination therapy is proposed as the method best suited. The preliminary results indicate that laser palliation of local relapse and soft tissue metastases might enlarge the therapeutic spectrum.

Laser surgery in gynecological oncology. Part I: Experimental results. Relapse and metastatic behaviour of the Lewis lung carcinoma subsequent to CO2 laser surgery of the primary tumor. An experimental model to compare the effectiveness of various CO2 laser application techniques.

The influence of various CO2 laser surgical techniques on tumor behaviour was examined in an experimental model on C56BL/6 mice (n = 106) with Lewis Lung carcinomas and compared with that of scalpel excised tumors. Comparisons were made between the healing procedure, the local recurrence rate, metastatic behaviour and the survival rate (n = 86) of mice after laser surgical excision of tumors, using the superpulsed and continuous wave techniques, with and without additional vaporisation of the wound, as well as after general vaporisation only.

[Microsurgical heterotopic ovary transplantation. A preclinical study]. / Mikrochirurgische heterotope Ovartransplantation. Eine präklinische Studie.

Free heterotopic autologous ovary transplantation might be a method to prevent iatrogenic radiocastration in case of Hodgkin's disease. Though first promising clinical case reports have been published, almost no experimental basic data are available. It was the aim of this study to develop a transplantation model in order to evaluate and improve operative technique and perioperative management preclinically. Whereas results in pilot transplantations on minipigs were impaired by the disposition to wound infections on the implantation site, transplantation on Beagle dogs proved to be a suitable model. Eleven transplantations have been performed (five in minipigs, six in Beagle dogs). The success rate of intact preserved transplants was 45% with an observation time of three months for the minipigs and 9 +/- 3.7 months for the dogs.

[Is co-administration of ethanol to the distension medium in surgical hysteroscopy a screening method to prevent fluid overload? A prospective randomized comparative study of ablative versus non-ablative hysteroscopy and various ethanol concentrations]. / Ist eine Ethanol-Beimengung im Distensionsmedium bei der operativen Hysteroskopie als Screening zur Vermeidung eines "Fluid overloads" sinnvoll? Eine prospektiv- randomisierte Vergleichsstudie von ablativer versus nichtablativer operativer hysteroskopie und unterschiedlichen Ethanol-Konzentrationen.

OBJECTIVE: Is it possible to diagnose early a beginning fluid absorption during operative hysteroscopy by adding ethanol to the distension medium? METHODS: A prospectively randomised comparative study of ablative versus non-ablative operative hysteroscopy with differing ethanol concentration was performed. Purisole (a mannitol/sorbitol solution) was used as distension medium. RESULTS: The results of the study show that at those hysteroscopical procedures at which the endometrium is not or only minimally injured (e.g. syneciolysis, hysteroscopic proximal tubal catheterisation) an intraoperative screening is not necessary due to the low absorbing amounts. At the hysteroscopical procedures as the resection of myoma, endometriumablation and septumresection, however, an addition of ethanol of 2% to the distension medium has proved to be useful, because with this method absorbing amounts from 400 mls can be established by positive values of breath alcohol. As the result of a further absorption of fluid, but delayed in time compared to the first positive value of breath alcohol, there is an increase of the central venous pressure and a hyponatraemia. CONCLUSION: The intraoperative ethanol-monitoring is a non-invasive procedure which can be performed at ablative-operative hysteroscopies and has no negative influence on the course of the intervention and the general condition of the patients.

[Change in the spectrum of uterus-preserving myoma operations including endoscopy and dual myoma therapy]. / Der Wandel des Spektrums uteruserhaltender Myomoperationen unter Einbeziehung von Endoskopie und dualer Myomtherapie.

OBJECTIVE: On the basis of the evaluation of 300 patients who underwent myoma surgery with the desire for uterus preservation at the Department of Obstetrics and Gynaecology of Heidelberg University, a management scheme including endoscopic techniques was developed. METHOD: Despite the patients' wish for organ preservation, in 12 cases (family planning complete, therapy-resistant sterility, no desire for a child) with an extremely large uterus (20th-24th week of gestation) or a degenerated, intramural myoma (a sarcoma not being excluded), a primary hysterectomy had to be performed. Overall, 37.9% of patients underwent conventional, 42% laparoscopic and 20.1% hysteroscopic surgery. Additionally, to objectify the role of a pretreatment with GnRH analogues (GnRHa), the following control parameters were examined in 128 patients with and 160 patients without pretreatment: rate of primary laparotomies, conversion, secondary hysterectomy, intraoperative bleedings, amount of distension medium and percentage of repeat interventions. RESULTS: No significant differences in the study parameters between study and control groups could be found in the patients treated by laparoscopy. In the hysteroscopy group, conversion rate (13.3 vs. 7%), operation time (35 vs. 21.9 min), rate of severe intraoperative bleeding (33.3 vs. 9.3%), amount of distension medium necessary (difference 2.1 litres) and rate of repeat interventions (40.4 vs. 16.3%) differed significantly between study and control groups. CONCLUSION: In the operative management, the key question is when to perform an invasive procedure. The second question should be which access route is the most convenient. The decision whether to give GnRHa pretreatment is also an individual one, especially in cases of a conventional or laparoscopic operative procedure. A preoperative GnRHa therapy is mandatory before hysteroscopy for submucous myoma.

Current and Future Status of Laparoscopy in Gynecologic Oncology.

Laparoscopy is playing an increasingly important role in gynecologic oncology. The benefits of minimally invasive surgery for oncology patients and the quality of this treatment are well documented. Outcomes and quality of minimally invasive surgical procedures to treat cervical cancer were evaluated based on retrospective and case-control studies; outcomes and quality after minimally invasive treatment für early-stage low-risk endometrial cancer were also assessed in prospective randomized studies. If indicated, laparoscopic lymphadenectomy is both technically feasible and oncologically safe. Adipose patients in particular benefit from minimally invasive procedures, where feasible. The potential role of laparoscopy in neoadjuvant therapy for ovarian cancer and in surgery for early-stage ovarian carcinoma is still controversially discussed and is currently being assessed in further studies. Using a minimally invasive approach in gynecologic oncology procedures demands strict adherence to oncological principles and requires considerable surgical skill.

Surgical Therapy of Endometriosis: Challenges and Controversies.

Endometriosis is one of the most common disorders encountered in surgical gynaecology. The laparoscopic technique, the planning of the surgical intervention, the extent of information provided to patients and the interdisciplinary coordination make it a challenging intervention. Complete resection of all visible foci of disease offers the best control of symptoms. However, the possibility of achieving this goal is limited by the difficulty of detecting all foci and the risks associated with radical surgical strategies. Thus, the excision of ovarian endometrioma can result in a significant impairment of ovarian function, while damage to nerve structures during resection of the uterosacral ligaments, the parametrium, the rectovaginal septum or the vaginal cuff to treat deep infiltrating endometriosis can lead to serious functional impairments such as voiding disorders. A detailed risk-benefit analysis is therefore necessary, and patients must be treated using an individual approach.

[Micro-endoscopy, minimal access endoscopy--an overview of current status and future possibilities]. / Mikroendoskopie, Minimal-Access-Endoskopie--Ein Uberblick über den derzeitigen Stand und zukünftige Möglichkeiten.

Based on technical and clinical application research a new generation of so-called micro-endoscopes was developed, with a wide range of indications in gynaecology as well. The innovative potential of these new endoscopes is, however, still to be considered against the background of the risks of erroneous findings at laparoscopical and hysteroscopical diagnosis, so that here too, clear indications will have to be worked out.

[Tubal catheterization and fallopian tube endoscopy for expanded diagnosis in tubal sterility]. / Tubenkatheterisierung und Falloposkopie zur erweiterten Diagnostik bei tubarer Sterilität.

The present study reports first experiences with falloposcopy for extended diagnosis in tubal sterility. In a total of 38 patients, n = 62 tubes were to be examined falloposcopically. Catheterization was successful in 85.5%. After successful catheterization, optically interpretable images were obtained in 93.6%. The overall success rate was therefore 80%. Considering the anatomical segments of the tube, no differences were found neither for catheterization nor for visualization. The spectrum of intratubal findings extended from normal in 25% to partly obstructive, nodular or non-nodular pictures, together with various degrees of mucosal alteration with or without synechia formation.

The HysteroTrainer, a simulator for diagnostic and operative hysteroscopy.

Hysteroscopy has become an integral part of operative gynecology, with rates of major complications of 1%. To avoid serious, even lethal, complications, an intensive, well-structured training program for practicing surgeons is necessary. In response to these educational requirements. The HysteroTrainer was developed to provide in vitro simulation training for diagnostic and operative hysteroscopy, including laser and high-frequency electrosurgery.
