Laparotomy and carbon dioxide laparoscopy are relatively traumatic and high-risk operations for patients. They may have negative effects on pregnancy, especially in advanced pregnancy. Gasless laparoscopy was performed on torqued hematosalpinx in a woman in the thirteenth week of pregnancy. After salpingectomy, the pregnancy proceeded normally.
OBJECTIVE: Compared to other procedures, gynaecological laparoscopies are followed rather frequently by postoperative nausea and vomiting (PONV). Therefore, we investigated the prophylactic antiemetic efficacy of metoclopramide and droperidol under general anaesthesia with isoflurane (part 1). Given the rather unsatisfying results of this monoprophylaxis we examined the effects of a quintuple prophylaxis in this setting (part 2). METHODS: Part 1: Following ethical committee approval and written informed consent 120 patients scheduled for elective gynaecological laparoscopy were allocated prospectively, randomly and observer-blinded to the following groups: group P (placebo): 2 ml NaCl 0.9 %, group D: 2.5 mg droperidol, group M: 10 mg metoclopramide. Part 2: Subsequently 50 patients scheduled for elective gynaecological laparoscopy and bearing a minimum risk of 25 % to experience postoperative vomiting were allocated prospectively and blinded to the observers to a quintuple prophylaxis group: group X: 10 mg metoclopramide, 2.5 mg droperidol, 12.5 mg dolasetron, 62.5 mg dimenhydrinate, 8mg dexamethasone. Part 1 and 2: Anaesthesia was induced with fentanyl, etomidate and succinycholine and maintained with isoflurane/N2O, fentanyl and cisatracurium. The antiemetics were applied intravenously 20 min prior to end of surgery. RESULTS: Within the first 24 h postoperatively vomiting occurred more frequently in group P (44 %) compared to group D (21 %, p = 0.046) and group M (33 %, n. s.). Nausea also occurred more frequently in group P (61 %) compared to group D (24 %, p = 0.003) and group M (48 %, n. s.). Intensity of nausea was reduced both in group D and group M compared to group P (p = 0.03). Likewise the requirements for antiemetics as a rescue medication were reduced in group D (p = 0.02) and group M (p = 0.047) compared to group P. In group X no patient suffered from postoperative vomiting, no patient required a rescue antiemetic. CONCLUSIONS: Whereas droperidol provides a reliable antiemetic effect, the prophylactic effect of metoclopramide is rather uncertain. Therefore, further studies regarding a dose response-relationship for metoclopramide are deemed necessary. Since a monoprophylaxis with droperidol or metoclopramide failed to attain a satisfying PONV-prophylaxis in patients at high risk for PONV, the quintuple antiemetic combination might be an effective and safe solution.

OBJECTIVES: The aim of our study was to investigate the role of the intact endometrium and ovaries for serum levels of insulin-like growth factor binding protein-1 (IGFBP-1) and glycodelin. STUDY DESIGN: In 35 premenopausal patients with a planned hysterectomy, serum measurements of IGFBP-1 and glycodelin were done before surgery and 1, 3, 5, and 10 days after surgery. Patients were divided into three groups according to the kind and time of operation: (1) hysterectomy with bilateral adnexectomy in the luteal phase and (2) hysterectomy without adnexectomy in the follicular phase or (3) the luteal phase. RESULTS: IGFBP-1-we could not show any differences in IGFBP-1 serum levels before and after hysterectomy with or without bilateral oophorectomy. Glycodelin-hysterectomized and oophorectomized patients showed decreasing serum levels up to day 3. After day 5, circulating concentrations of glycodelin increased continuously but remained below pre-operative levels. In both non-adnexectomized groups we saw a reduction up to day 5 but a rise at day 10. None of the results reached statistical significance. CONCLUSION: The results indicate that endometrium and ovary are not the only sources of IGFBP-1 and glycodelin.
Bilateral ovarian fibromas are a rare condition. We report a case of bilateral ovarian fibromas with endometrial adenocarcinoma in a postmenopausal woman who clinically showed symptoms of an estrogen-producing tumour. Clinical and histopathological problems in the pre- and intraoperative diagnostics of fibromas are discussed.
OBJECTIVE: To assess the diagnostic value of maternal CA 125 in patients with symptomatic first trimester pregnancy and to evaluate the prognostic significance of CA 125 versus beta-hCG in early pregnancies with intact fetal heartbeat, complicated by vaginal bleeding. STUDY DESIGN: Two prospective open-label studies with longitudinal follow-up in the second trial. SETTING: Academic Department of Obstetrics and Gynecology, University of Cologne. PATIENTS: Study 1: 168 patients presenting between gestational weeks 6 and 12 with: extrauterine pregnancy, 29; missed abortion, 50; incomplete spontaneous abortion, 38; imminent abortion, 33; and normal pregnancy (no history of endometriosis or ovarian mass), 18. Study 2: Fifty consecutive patients with vaginal bleeding during gestational weeks 6-12 all of whom having demostrable fetal heartbeat. Eighteen patients finally aborted whereas the remainder had normally continuing pregnancy until term. MAIN OUTCOME MEASURE: Study 1: Single serum determinations of CA 125 and beta-hCG were correlated with the different disorders observed. Study 2: Two sequential measurements of serum CA 125 and beta-hCG performed within a 5-7 days interval were related to the outcome of pregnancy as indicated by changes of the ultrasound presentation, miscarriage, future hospitalization, or delivery. RESULTS: Study 1: Patients with vaginal bleeding generally had higher median CA 125 values (38 IU/ml; range 1.3-540) compared to non-bleeding patients (17.8 IU/ml; range 1.0-157). No statistically significant differences in regard to median serum CA 125 levels between symptomatic and normal pregnancies occurred: normal pregnancy, 25.5 IU/ml (range 3.2-97); ectopic pregnancy, 26 IU/ml (range 1.3-157); missed abortion, 19.1IU/ml (range 1-242); threatened abortion, 48 IU/ml (range 5.2-540); spontaneous abortion, 40 IU/ml (range 5.4-442). Study 2: Initial CA 125 levels did not differ significantly between both groups of patients with 27/32 non-aborters and 13/18 aborters showing concentrations below 65 IU/ml. After 5-7 days, CA 125 in all patients who eventually aborted remained high or increased whereas non-aborters all had constantly low or steeply declining CA 125 measures. beta-hCG increased in all non-aborters but also in 13/18 aborters during the 5-7 day interval. CONCLUSION: Single serum measurements of CA 125 in symptomatic first trimester pregnant patients failed to discriminate spontaneous abortion, ectopic or normal pregnancies. However, sequential determinations of maternal CA 125 measurements appear to be a highly sensitive prognostic marker in patients with viable pregnancy at risk for abortion.
A 37-year-old patient had recurring thromboses, occlusion of the left femoral vein with hereditary hyperhomocysteinemia, hypermenorrhea and anaemia. Conservative therapy with endometrium ablation and gestagene failed. A supracervical hysterectomy was done to preserve the presacral and left lateral, dorsal and caudal collaterals beside the uterus, and prevent a postoperative congestion, especially of the left leg.
BACKGROUND: Anticardiolipin auto-antibodies are known to be inflicted in recurrent pregnancy losses and other adverse outcomes of pregnancy. However, their role in extrauterine pregnancies is unknown. OBJECTIVE: To clarify the association between anticardiolipin antibodies and extrauterine pregnancies. PATIENTS AND METHODS: About 30 patients with ectopic pregnancies confirmed histologically and 40 control subjects with intrauterine pregnancies were studied. Mean duration of pregnancy was 38 and 39 days, respectively. Serum levels of IgG, IgA, and IgM antibodies against cardiolipin were measured. In addition, measurements of human chorionic gonadotropin (beta hCG) and progesterone were made. RESULTS: Mean levels of IgA and IgM but not IgG antibodies were significantly higher in patients with ectopic pregnancies than in normal pregnant women. Distribution frequency histograms revealed that a subgroup of ectopic pregnancies exhibit antibody titers corresponding to that of intrauterine pregnancies, and others showing elevated levels. Markedly elevated antibody levels were observed in patients having low levels of beta hCG and/or progesterone. CONCLUSION: In view of the inflammatory events associated with some cases of ectopic pregnancies, elevated levels of anticardiolipin auto-antibodies may give clues to pathogenesis. Determination of IgM antibodies may help discriminate ectopic pregnancies with auto-immune pathogenesis from those caused by other factors.
Ectopic pregnancies sited in dehiscent cesarean section scars have a high risk of rupture and bleeding. Attempts at operative therapy frequently end in loss of the uterus. A connection with the cavum uteri justifies an attempt at dilatation and curettage. We describes a patient with combined systemic and local intra-amniotic methotrexate (MTX). The uterus was preserved.

OBJECTIVE: The following retrospective study is intended as a contribution towards determining the necessity of a hysteroscopic metroplasty in patients with primary infertility. - MATERIAL AND METHODS: 21 patients with primary infertility and a septate uterus, who had undergone a hysteroscopic dissection of the septum between 1993 and 2000, were evaluated. With the help of medical records, operation reports, standardised questionnaires as well as telephone contact with the patient's doctor and/or the patient, anamneses, operation as well as postoperative development were recorded. - RESULTS: All dissections of the septum occurred without complication. During follow-up (median 24.0 +/- 23.7 months), 11/21 patients became pregnant (52.4 %). Of these 11 pregnancies, 7 ended (63.3 %) at full-term, 2 (18.2 %) prematurely and one (9.1 %) as a miscarriage. One pregnancy is currently in the 3(rd) trimester. - CONCLUSIONS: The hysteroscopic metroplasty demonstrates a low intra- and postoperative rate of complication. Particularly the indication of a lower rate of miscarriages, possibly of an increase in the pregnancy rates, should, in our opinion, give reason to proceeding with a diagnostic hysteroscopy, especially prior to extensive sterility therapies. Where suspicion exists of a septum > 1.0 cm, this should be corrected by means of an operative hysteroscopy.
Transvaginal hydrolaparoscopy (THL) was evaluated in comparison with the already established chromolaparoscopy in the detection of tubal factors, adhesions as well as endometriosis. 43 infertile patients without previous pelvic operations and with an inconspicuous clinical examination were included in a prospective comparative study of THL and chromolaparoscopy. THL succeeded in 40 patients (93.0%). Both methods showed 100% agreement with regard to tubal factors and adhesions. However, only 72/80 tubes (90.0%) could be portrayed by THL. In contrast to this, THL failed to identify 8 of 10 laparoscopically verified endometrioses (isolated endometriosis of the bladder peritoneum in 2). No complications occurred with THL. THL could be the method of choice for the clarification of mechanical infertility factors in symptom-free patients with no suspicion of pelvic pathologies. Tubal pathologies and/or adhesions (visible during THL) should be indications for laparoscopy. In the case of inconspicuous genitals during THL and a still unfulfilled desire for offspring postoperatively, laparoscopy should be considered in order to exclude the possibility of unidentified endometriosis. Retroflexio uteri should at least be a relative contraindication for THL. Further studies are necessary to evaluate the role of THL in the diagnostic concept of infertility in the future.

OBJECTIVE: To evaluate the efficacy, safety and tolerability of continuous combined hormone replacement therapy (HRT) with Climodien (estradiol valerate 2 mg plus dienogest 2 mg). DESIGN: Open, multinational, multicenter, non-controlled phase III study. PARTICIPANTS: A total of 1501 women aged 52-65 years with postmenopausal symptoms of sufficient severity to require treatment. METHODS: Eligible patients were treated with Climodien for 12 treatment cycles (48 weeks), with assessments of efficacy, safety and tolerability (adverse events) at 8, 24 and 48 weeks. Efficacy was assessed using the Kupperman index. Safety assessments included endovaginal sonography, safety endometrial biopsies, mammography, physical and gynecological examination, vital signs, prothrombotic factors and routine laboratory safety parameters. RESULTS: The Kupperman index improved with increasing duration of treatment, accompanied by an improvement in self-reported patient well-being. Individual climacteric symptoms such as hot flushes and psychonervous disorders also improved. The most pronounced improvement was seen in women who had not previously used HRT. The incidence of breakthrough bleeding declined over time, resulting in complete amenorrhea in 86.2% of the patients after 12 cycles of treatment. Furthermore, total and low-density lipoprotein (LDL) cholesterol levels decreased and high-density lipoprotein (HDL) cholesterol levels increased. Decreases in alkaline phosphatase, pyridinoline and deoxypyridinoline demonstrated the inhibitory action of estradiol on bone resorption. Endometrial thickness remained almost constant, and the incidence of serious endometrial findings was similar to that in untreated women. CONCLUSIONS: Continuous combined estrogen-progestin therapy with Climodien is effective, safe and well tolerated in postmenopausal women, with a profile and incidence of adverse events consistent with those of existing HRT preparations.
Our report concerns a patient with a climacterium praecox and an X-chromosomal anomaly (86% 46, XX; 7% 47, XXX; 7% 45, X0) desiring to give birth. She conceived once after down-regulation of the gonadotrophins by means of a cyclical hormone replacement therapy followed by gonadotrophin stimulation, as well as a second time under down-regulation with a GnRH-analogue and gonadotrophin stimulation. On the basis of the case report and of the literature, a possible interval therapy in such a patient, especially one even with increasing ovarian insufficiency, will be portrayed and discussed.
OBJECTIVE: To compare endometrial ablation and levonorgestrel-IUS for treatment of refractory reccurrent hypermenorrhea. STUDY DESIGN: 30 patients with refractory recurrent hypermenorrhea were included in a prospective controlled comparative study. A transcervical Roller-Ball ablation was carried out in 15 patients after a 2-months GnRH analog pretreatment. A levonorgestrel IUD (MIRENA(R), Schering AG Berlin, Germany) was inserted in 15 patients for the treatment of hypermenorrhea. In a follow-up of the bleeding behavior over 12-24 months a reduction of bleeding was achieved in 14 of 15 patients after Roller-Ball ablation and in 11 of 15 patients after levonorgestrel IUD insertion. The amenorrhea rates are roughly the same in both groups. Side effects of levonorgestrel IUS were rare and mostly temporary. CONCLUSIONS: The insertion of a levonorgestrel IUD for the local hormonal treatment of recurrent hypermenorrhea refractory to oral treatment can be tried before endometrial ablation. The MIRENA(R) device is particularly advantageous for younger patients who might wish to have more children. The levonorgestrel IUD treatment can replace approx. 75% of endometrial ablations.
OBJECTIVE: In order to assess the efficacy and tolerability of leuprorelin acetate depot in pre-operative flattening of the endometrium prior to hysteroscopic endometrial ablation, 94 patients from eight centres were included in the per protocol analysis. MATERIAL AND PATIENTS: The patients included were pre- or peri-menopausal, had completed their family planning and had intractable uterine bleeding. The primary target criterion was the reduction in maximum endometrial thickness after two injections of leuprorelin acetate depot with an interval of four weeks between injections. Surgery took place two weeks after the second injection. RESULTS: Sufficient pre-treatment was achieved in 91.5% of the patients with > 50% decrease and/or a type 1 endometrium according to sonographic and/or endometrial atrophy (Score 11) according to the central histological evaluation. The endometrium was flattened by a mean of 4.0 +/- 4.1 mm. In terms of clinical response, amenorrhoea, hypomenorrhoea or normal menstruation were achieved after endometrial ablation. Hence 91.5% of patients benefited from the overall treatment after six weeks and still 83% after six months. The trial medication was well tolerated overall. The most common side-effect described was hot flushes which could be attributed to the deliberate oestrogen withdrawal. CONCLUSION: In view of the good study results, hormone-suppressive pretreatment of the endometrium can be recommended prior to elective ablation. Surgery should take place during the oestrogen-suppressed phase.
Leptin is mainly synthesized by adipocytes and might represent the connecting link between fatty tissue and brain. In reference to reproduction, leptin resistance could play a role particularly in the pathogenesis of the PCO syndrome. However, there exists at present contradictory data on this, so that further clarification is necessary. Leptin interacts with the steroid synthesis to a degree not yet precisely clarified and possesses receptors in numerous tissues, which suggests extensive local and endocrine effects. Its exact significance for the initiation of puberty still remains unknown. The same is true for first data regarding leptin and endometriosis and the interpretation of hyperleptinemia during pregnancy. It is clear that this protein mediates between fatty tissue and the reproductive function. However, the detailed physiologic and pathophysiologic role of leptin in reproduction can only be clarified through further extensive studies. To date there is not yet a practical importance for the measurement of leptin in routine work in reproductive medicine.
