The first robotic-assisted hysterectomy below the bikini line with the Dexter robotic system™.

Background: Robotic-assisted hysterectomy (RAH) is a widely accepted minimally invasive approach for uterus removal. However, as RAH is typically performed in the umbilical region, it usually results in scars in cosmetically suboptimal locations. This is the first case of RAH with cervicosacropexy performed below the bikini line, using the new Dexter robotic system™. Objectives: The aim of this article is to show the surgical steps of the first RAH with cervicosacropexy performed below the bikini line with the new Dexter robotic system™ (Distalmotion), and furthermore assess the feasibility of this approach using this robotic platform. Materials and Methods: A 43-year-old woman with uterine adenomyosis and recurrent uterine prolapse underwent a robotic-assisted subtotal hysterectomy with cervicosacropexy, performed below the bikini line, using the Dexter robotic system™, at the Clinic of Gynecology and Obstetrics at Universitätsklinikum Schleswig-Holstein (UKHS) in Kiel, Germany. Main outcome measures: Perioperative data, surgical approach specifics, objective, and subjective outcomes of this new approach. Results: The procedure was performed without intra-operative complications; estimated blood loss was 10 ml. Operative time was 150 minutes, console time 120 minutes, total docking time 6 minutes. Dexter performed as expected; no device-related issues or robotic arm collisions occurred. The patient did not require pain medication and was released on the second postoperative day. Conclusion: RAH performed below the bikini line using the Dexter robotic system™ is a feasible, safe, and adequate procedure. These initial results should be confirmed and further extensively refurbished with larger patient cohorts, and functional and psychological outcomes need further investigation.

Critical Role of 3D ultrasound in the diagnosis and management of Robert's uterus: a single-centre case series and a review.

A septate uterus with a non-communicating hemicavity was first described by Robert in 1969/70 as a specific malformation of the uterus. The condition is commonly associated with a blind uterine hemicavity, unilateral haematometra, a contralateral unicornuate uterine cavity and a normal external uterine fundus. The main symptoms are repetitive attacks of pain at four-weekly intervals around menarche, repeated dysmenorrhea, recurrent pregnancy loss and infertility. In this report, we review the disease, its diagnosis and treatment, and describe five cases of Robert's uterus. Three dimensional (3D) ultrasound (US) imaging was performed by the transvaginal route in four cases. In the fifth case of a 13-year-old girl, we avoided the vaginal route and magnetic resonance imaging (MRI) and 3D transrectal US yielded the correct diagnosis. The following treatment procedures were undertaken: laparoscopic endometrectomy, hysteroscopic septum resection, laparoscopic uterine hemicavity resection and total laparoscopic hysterectomy (TLH). The diagnosis and optimum treatment of Robert's uterus remains difficult for clinicians because of its rarity. A detailed and careful assessment by 3D US should be performed, followed by hysteroscopy in combination with laparoscopy, to confirm the diagnosis.

Incidence of unexpected uterine malignancies after electromechanical power morcellation: a retrospective multicenter analysis in Germany.

PURPOSE: During the last decade, electromechanical power morcellation (EMM) was more frequently used but it may be associated with the dissemination of occult malignancies. The aim of the present study was to determine the frequency of unexpected uterine malignancies after EMM. METHODS: This retrospective study consisted of patients who were treated at three departments of Gynecology in Germany from 2008 to 2017. We identified women who underwent an operation with the use of EMM. Clinical records, risk factors, and the outcomes of the patients were reviewed. RESULTS: We performed an analysis of 1683 patients who had undergone laparoscopic supracervical hysterectomy (LASH), total hysterectomy, or myomectomy (LM) (48.6%, 8.4%, and 43.0%, respectively). Unexpected malignancies were detected in 4 of 1683 patients (0.24%). In all cases, the malignancy proved to be a sarcoma and was detected after LASH. All patients with occult sarcomas were older than 45 years and the most common (75%) risk factor was the appearance of a solitary tumor. The patients underwent secondary laparotomy for complete oncological staging, and no histological dissemination of the sarcoma was registered. Two patients had a recurrence. At the final follow-up investigation all four patients were in good general health. CONCLUSION: Occult malignancies are liable to spread after EMM, although the overall risk of being diagnosed with an occult malignancy and the risk of dissemination appear to be low. Once the preoperative diagnostic investigation has yielded no suspicious findings, laparoscopic morcellation may be considered a safe method, especially LM in patients of reproductive age.

[Interdisciplinary Diagnosis and Treatment of Deep Infiltrating Endometriosis]. / Interdisziplinäre Diagnostik und Therapie der tief infiltrierenden Endometriose.

Endometriosis is the second most common benign female genital disease after uterine myoma. This review discusses the interdisciplinary approach to the treatment of deep infiltrating endometriosis. Endometriosis has been defined as the presence of endometrial glands and stroma outside the internal epithelial lining of the cavum uteri. As a consequence, endometriosis can cause a wide range of symptoms such as chronic pelvic pain, subfertility, dysmenorrhea, deep dyspareunia, cyclical bowel or bladder symptoms (e.g., dyschezia, bloating, constipation, rectal bleeding, diarrhoea and hematuria), abnormal menstrual bleeding, chronic fatigue or low back pain. Approx. 50 % of teenagers and up to 32 % of women of reproductive age, operated for chronic pelvic pain or dysmenorrhoea, suffer from endometriosis. The time interval between the first unspecific symptoms and the medical diagnosis of endometriosis is about 7 years. This is caused not only by the non-specific nature of the symptoms but also by the frequent lack of awareness on the part of the cooperating disciplines with which the patients have first contact. As the pathogenesis of endometriosis is not clearly understood, a causal treatment is still impossible. Treatment options include expectant management, analgesia, hormonal medical therapy, surgical intervention and the combination of medical treatment before and/or after surgery. The correct treatment for each patient should take into account the severity of the disease and whether the patient desires to have children. The treatment should be as radical as necessary and as minimal as possible. The recurrence rate among treated patients lies between 5 and > 60 % and is very much dependent on the integrated management and surgical skills of the respective hospital. Consequently, to optimise the individual patient's treatment, a high degree of interdisciplinary cooperation in diagnosis and treatment is crucial and should, especially in the case of deep infiltrating endometriosis, be undertaken in appropriate centres.

Changes of salivary estrogen levels for detecting the fertile period.

OBJECTIVES: Is the saliva test, Geratherm ovu control, as accurate as the established urinary luteinizing hormone (LH) test for detecting ovulation and the following the fertile period? STUDY DESIGN: The voluntary participants were 74 healthy women with regular menstrual cycles and not using any hormonal contraceptives. The women used Geratherm ovu control, a small plastic hand-held microscope, for detecting the fertile period. A drop of saliva from sublingual was put onto the lens of the microscope. Three results were possible: non-fertile (dot pattern), transitional and fertile (ferning pattern). The participants performed the saliva test from the 5th till the 22nd day of the menstrual cycle and noted the respective result in a table. In addition to Geratherm ovu control, the EXACTO test for determining urinary LH concentration and the time of peak fertility was also performed. RESULTS: Positive LH shows a sharp increase beginning on the 10th cycle day with a maximum on the 17th cycle day. The curve for positive saliva and questionable positive saliva (one curve) is almost parallel with the curve for positive LH, reaching a maximum on the 16th cycle day. There is a high level of conformity for the same test results from the 5th (100%) till the 14th (84%) cycle day and from the 18th (80%) till the 22nd (96%) cycle day which corresponds to the pre- and post-ovulatory period. CONCLUSION: The saliva and the LH test both detect the fertile window of a menstrual cycle. Caused by the different hormones (estrogen for the saliva and LH for the LH test) leading to the respective positive test results, saliva turns positive 24h before LH. Consequently, the saliva test can be used as an ovulation test and help women maximize their chances of conceiving. There is also a high congruence between LH and saliva in the pre- and post-ovulatory period, indicating that the saliva test can also be used for contraception purposes.

Ovulation detection in saliva, is it possible.

BACKGROUND/AIMS: The new mini-microscope Geratherm® ovu control was evaluated for its recognition of saliva ferning in a collective of 47 patients taking part in an artificial reproductive technology program on the day of follicular puncture. METHODS: The ferning phenomenon was evaluated by patients and laboratory staff according to the criteria: no ferning, slight ferning and good ferning. RESULTS: Geratherm® ovu control showed a specificity of 78% and a sensitivity of 80% in relation to rising E2 levels under follicle-stimulating hormone/human chorionic gonadotrophin. A comparison of the evaluations of the saliva test carried out by patients and by laboratory staff resulted in a high and substantial agreement of 89.4% (κ). CONCLUSION: Evaluations performed by ovu control were similar to those achieved with a highly sophisticated inverted microscope.

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.

The value of laparoscopic surgery to stage gynecological cancers: present and future.

The laparoscopic management of gynecologic cancers has been discussed controversely since decades. Much progress has been achieved technically enabling an experienced endoscopic surgeon to perform most of the gynecologic oncologic procedures such as hysterectomy, omentectomy, pelvic and paraaortic lymph node dissection. Although the value of laparoscopy with respect to oncological safety and patient's outcome has not been shown in prospective randomized clinical trials, many studies with altogether thousands of patients have revealed the feasibility and also similar oncologic results of laparoscopy when compared to laparotomy. Therefore, the laparoscopic approach has become well accepted for certain oncological indications, especially when early stage cancer cases are treated. These indications are also subject to ongoing Phase III trials: The LACC001 trial compares Total Laparoscopic Radical Hysterectomy (TLRH) or total robotic radical hysterectomy with total abdominal radical hysterectomy (TARH) for the treatment of early stage cervical cancer. The GOG LAP 2 and also the LACE001 trial compare total laparoscopic hysterectomy (TLH) with total abdominal hysterectomy (TAH) for the treatment of early stage endometrial cancer, whereby bilateral salpingo-oophorectomy, pelvic and paraaortic lymph node dissection is performed according to tumor stage and grade. This review summarizes the current status of laparoscopy in gynecologic oncology based on the literature to date, the ongoing clinical trials, and the recommendations of the German Gynecologic Oncology Group (AGO).

A safety and efficacy study of a resorbable hydrogel for reduction of post-operative adhesions following myomectomy.

BACKGROUND: This multicenter, randomized, single-blind study assessed the safety and efficacy of a resorbable hydrogel ('Hydrogel') for the reduction of post-operative adhesion formation following myomectomy. METHODS: Women (n = 71) who were undergoing laparoscopic (67.6%) or laparotomic myomectomy were randomized (2:1) to Hydrogel (sprayed over surgically treated areas prior to wound closure, n = 48) or to control (standard care, n = 23). Patients (38 Hydrogel, 20 control) returned 8-10 weeks later for a second look. Adhesions were graded using a modified American Fertility Society (mAFS) scoring method. The primary efficacy measure was the posterior uterus mAFS score. RESULTS: For Hydrogel and control patients, respectively, mean +/- SD mAFS scores were 0.5 +/- 1.4 and 0.0 +/- 0.0 at baseline, and 1.1 +/- 1.9 and 2.6 +/- 2.2 at the second look. Similarly, mean changes from baseline were 0.8 +/- 2.0 and 2.6 +/- 2.2 (P = 0.01); 95% confidence intervals for these mean changes were (0.16-1.44) and (1.64-3.56). Adverse events were reported by 9.6 and 17.4% of Hydrogel and control patients, respectively. No intra-abdominal infections or post-operative site infections were reported. CONCLUSIONS: This 71-patient study provides the first clinical evidence of the safety and efficacy of Hydrogel for the reduction of adhesions following myomectomy. The ClinicalTrials.gov Identifier is NCT00562471.

Three singleton deliveries with healthy children from one couple after cryo-tESE and ICSI.

UNLABELLED: We report on a couple who delivered three healthy babies in three deliveries after cryo-TESE combined with ICSI. The male patient suffers from congenital bilateral absence of the vas deferens (CBAVD). METHODS: Three testicular sperm extraction (TESE) operations were performed in the male accompanied by six stimulated ICSI cycles in the female patient. Altogether, 59 oocytes were retrieved. Fifty-one oocytes (86%) were in metaphase II and 38 fertilized regularly (75%). Sixteen embryos, in the 3-6 cell stage, were transferred to the uterus. RESULTS: The first, fifth and sixth embryo transfers of fresh embryos led to intact intrauterine singleton pregnancies. The pregnancy and implantation rates with fresh embryos were 50% and 20%, respectively. CONCLUSIONS: TESE or microscopic epididymal sperm aspiration in patients with CBAVD in combination with a healthy female partner is likely to yield very good results in ICSI/ET. As azoospermia can be caused by cystic fibrosis and cystic fibrous transmembrane conductance regulator gene mutation range varies dramatically in patients of different ethnic groups.

Comparison of c-DNA microarray analysis of gene expression between eutopic endometrium and ectopic endometrium (endometriosis).

PROBLEM: As recent studies have suggested abnormalities in the regulation of specific genes in the development of endometriosis, we investigated differentially expressed genes in endometriosis compared to endometrium. METHOD OF STUDY: Gene expression profiles using the Atlas microarray were performed in endometriotic tissue and endometrium. Nine of the 13 genes of endometriotic tissue showed an up-regulation in relation to endometrium and four of the 13 genes a down-regulation. RESULTS: Of the 1176 genes on the Atlas Human 1,2 array, only 13 differentially expressed identical genes were detected after repeating the gene analysis three times. CONCLUSION: According to our c-DNA analysis some differentially expressed genes may be involved in the pathogenesis of endometriosis. An imbalance in the genes responsible for the reproductive process may lead to a decrease in embryo implantation in patients with endometriosis.

Ectopic pregnancy treatment by laparoscopy, a short glimpse.

Ectopic pregnancy is a life-threatening emergency, the incidence of which is increasing globally. There are a number of factors predisposing to this condition; today, the most common of these is salpingitis. Due to advancements in diagnostic technology it is possible to diagnose this condition early and thus try to achieve a favourable outcome for the patient. Treatment options in the form of medical and surgical modalities are widely available. As minimally invasive therapy techniques are rapidly advancing, laparoscopic treatment has become the most popular and preferred method for treating ectopic pregnancy. Both salpingotomy as well as salpingectomy can be performed through the laparoscope. This paper gives a short glimpse at the predisposing factors and the diagnostic investigations available for ectopic pregnancy and an insight into its laparoscopic treatment. It also reviews the pregnancy outcome and laparoscopic treatment of cases at the Department of Obstetrics and Gynaecology, Campus Kiel, University Hospitals Schleswig-Holstein.

Is granulocyte colony-stimulating factor level predictive for human IVF outcome?

BACKGROUND: We investigated granulocyte colony-stimulating factor (G-CSF) in human reproduction. METHODS: From a total sample of 93 patients, we analysed in group 1 (n = 82) the level of G-CSF and estradiol (E(2)) in serum and follicular fluid (FF) on day of follicular puncture (FP). Furthermore, in response to ovarian stimulation, G-CSF levels in serum were compared between low (n = 11), moderate (n = 53) and high (n = 18) response patients. In group 2 (n = 23) serum for G-CSF assessment was collected throughout menstrual cycle until gestation. Group 3 (n = 11) patients with endometriosis were assessed for G-CSF in serum and FF on day of FP without further differentiation. RESULTS: G-CSF in FF was higher than in serum (P < 0.01). G-CSF in serum increased from low through moderate to high response (P < 0.001); pregnancy rates were 0, 24.5 and 33.5% respectively. G-CSF in serum increased throughout stimulation, reached a peak with ovulation induction (P = 0.01) and decreased until embryo transfer (P=0.001). G-CSF level only in pregnant patients (n = 11) increased from embryo transfer to implantation to gestation (P = 0.005). In endometriosis patients G-CSF in serum and FF was lower than in non-endometriosis patients (P < or = 0.03) and corresponded with low response patients. CONCLUSIONS: G-CSF is involved in follicle development and may be a predictor of IVF outcome.

Laparoscopic hysterectomy: challenges and limitations.

Twenty years after the first description of vaginal hysterectomy with laparoscopic assistance by Kurt Semm in 1984 (1), and 16 years after the publication of the so-called laparoscopically assisted vaginal hysterectomy (LAVH) by Harry Reich in 1989 (2), it is time to review and evaluate the real benefits of laparoscopic hysterectomy. Although laparoscopic surgery is well accepted by gynaecologists worldwide for the treatment of certain gynaecological conditions, laparoscopic hysterectomy in Germany, and probably worldwide, is still only performed by a few specialists. Highly skilled surgical techniques, longer operating time and expensive technology are suggested to be the deterring factors. Laparoscopic hysterectomy, in its different forms, is an attractive and safe procedure for the management of benign gynaecological conditions and many authorities recommend its use on a larger extent. On the other hand, in our opinion, the use of laparoscopic hysterectomy for oncological indications is still controversial. Extensive experience of over 15 years, of the first author, in practising and teaching various forms laparoscopic hysterectomy, namely, laparoscopically assisted vaginal hysterectomy (LAVH), total laparoscopic hysterectomy (TLH), classic intrafascial supracervical hysterectomy (CISH) and laparoscopic supracervical hysterectomy (LSH), has led us to the firm conclusion that these techniques are advantageous to patients if performed for the appropriate indication. In particular, subtotal or supracervical hysterectomy, with the cervix remaining in its place, is associated with fewer complications and a very favourable outcome for the patient. Radical laparoscopic vaginal hysterectomy (RLVH), the last variant in our exposé, is only successful in an expert's hands. The surgical techniques of these varieties of laparoscopic hysterectomies will be described and illustrated in detail in this paper.

Experience of laparoscopic tubal surgery at the department of obstetrics and gynecology, University of Kiel, from 1999 through 2000.

OBJECTIVE: We analyzed the results of laparoscopic tubal surgery performed at the Department of Obstetrics and Gynaecology, University of Kiel, between 1999 and 2000. A retrospective review of 236 tubal surgical procedures was conducted: (1) patients with ectopic pregnancies, unilateral or bilateral tubal occlusions or alterations and (2) medically indicated sterilizations and salpingectomies. METHODS: Two specialists and 10 gynecologists in residency training performed the following 236 procedures: 64 salpingotomies, 74 salpingectomies, 25 salpingostomies, 8 tubal end-to-end anastomoses, 24 fimbrioplasties, and 41 tubal sterilizations. In June 2001, questionnaires were sent to all 236 patients who underwent laparoscopic tubal surgery to evaluate subsequent pregnancies. From the 195 answers received, 155 patients wished to have children and of these 79 (51%) became pregnant. In 8 tubal reversals, 6 pregnancies occurred, resulting in a 75% success rate. In the group of sterilizations and salpingectomies, no pregnancies occurred. RESULTS: A pregnancy rate of 51% resulted after tubal reconstructive surgery. After tubal sterilization, no pregnancies were observed in the following 3 years. CONCLUSION: Laparoscopic tubal surgery has surpassed laparotomic tubal surgery with comparable success rates. Laparoscopic tubal surgery is also a less traumatic procedure.

Correlation of endoscopic interpretation of endometriosis with histological verification.

INTRODUCTION: In this study we correlate the laparoscopic findings of endometriosis with the histological confirmation of the disease over a period of two years. MATERIALS AND METHODS: One hundred and sixty-four laparoscopies performed at the Department of Gynecology & Obstetrics, University of Kiel, over a two-year period were reviewed for laparoscopic findings and histological confirmation of endometriosis. RESULTS: The majority of patients suspected of endometriosis at laparoscopy were confirmed by histological examination, i.e. 138 out of 164 patients (84.1%). CONCLUSION: Laparoscopy is the easiest diagnostic tool for the diagnosis of endometriosis which can be confirmed by histological examination.
