Laparoscopic management of asymmetric Mayer-Rokitansky-Kuster-Hauser syndrome.

Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome is a partial or complete absence (agenesis) of the uterus with an absent or hypoplastic vagina. Until now, the recommended treatment, when resection of a rudimentary horn was indicated, was laparotomy. We report a case of MRKH syndrome in which the patient benefited from laparoscopic surgery for bilateral resection of rudimentary horns. Laparoscopy is not only useful for diagnosis of uterine malformations but can also be valuable for any treatment required for this type of malformation, this being carried out during the same operative procedure, thus avoiding laparotomy for the patient. The creation of an artificial vagina is performed during a second operation.

Sterilization reversal: fertility results.

Fertility outcome following sterilization reversal by laparotomy was evaluated. We studied all sterilization reversals performed between January 1978 and December 1991; a total of 226 women were treated. Tubal anastomosis was performed according to the rules for microsurgery. The microsurgical technique comprised two main phases: preparation of the healthy tube segments and the anastomosis carried out on two layers. It was possible to study the subsequent fertility of 206 patients in all, as 20 patients were lost to follow-up (8.8%). Cumulative pregnancy rates were evaluated by life-table analysis. The overall intrauterine pregnancy rate, including births and miscarriages, was 69.9% (144 patients) after 2 years. The cumulative intrauterine pregnancy rate was 62% at 18 months. Analysis of the fertility results demonstrated that age was the most significant predictive factor. The cumulative intrauterine pregnancy rate at 2 years was 83.5% (61 cases) for patients < or = 33 years, 70% (35 cases) for patients aged 34-36 years, 62.5% (30 cases) for patients aged 37-39 years, and 51.4% (18 cases) for patients aged > or = 40 years. Even for patients aged approximately 40 years, microsurgical repermeabilization can be retained as the first choice rather than in-vitro fertilization.

Uterine rupture during pregnancy after laparoscopic myomectomy.

A 31 year old patient presenting with primary infertility underwent an operative laparoscopy for the treatment of bilateral hydrosalpinges, during which a myomectomy was also performed. The uterus was repaired using interrupted sutures. At follow-up laparoscopy seven weeks later, a uterine fistula was diagnosed and was oversewn using a single 'figure of eight' suture. One year later the patient became pregnant through in-vitro fertilization. At 34 weeks gestation, she required an emergency laparotomy for acute abdominal pain and the presence of fetal bradycardia. The operative findings revealed a uterine rupture at the site of the previous myomectomy scar. This was then enlarged with a scalpel and a live baby was delivered. The uterus was repaired in two layers. The postoperative period for both mother and baby was satisfactory. This complication raises the problem of the quality of uterine repair following laparoscopic myomectomy, together with the question of how to prevent this type of life-threatening situation.

Transcervical tubal cannulation and falloposcopy for the management of tubal pregnancy.

This is the first report of transcervical salpingoscopic visualization of tubal pregnancy in two patients. The falloposcope was introduced through a catheter used routinely for transcervical tubal cannulation, guided by tactile impression. We have previously demonstrated that it is possible to diagnose and treat tubal pregnancies via a transcervical intra-Fallopian cannula. Falloposcopy could help select appropriate patients for transcervical intra-Fallopian therapy by verifying the site of implantation and the characteristics of the ectopic pregnancy.

[Complications of gynecologic laparoscopy. Multicentric study of 7,604 laparoscopies].

In a series of 7,604 laparoscopic procedures, the authors report one death and a rate of 2.76 per thousand (21 cases) for complications requiring laparotomy. When exclusively diagnostic laparoscopic procedures are considered (1,191 cases) this rate drops to 1.67 per thousand. The likelihood of laparotomy being required is directly related to the degree of importance of the laparoscopic surgical procedure. For major laparoscopic surgery the rate of laparotomy is 4.46 per thousand (18 cases), whereas it is only 0.42 per thousand (1 case) for minor laparoscopic surgery (p less than 0.01). Intestinal injuries represent 52.4% (11 out of 21) of cases requiring laparotomy. The main problem with this type of accident is to recognize them, because in almost half the cases (42.8%; 3 out of 7) the intestinal injury went unseen during the laparoscopic procedure and gave rise to peritonitis. Vascular complications are less frequent and required laparotomy in only 8 cases (38%; 8 out of 21). This low level of complications is yet further proof that laparoscopic surgery is a reliable technique and does not involve a high risk of laparotomy, provided that the surgeon has received specific training.

Role of gonadotrophin-releasing hormone agonists in the treatment of external genital endometriosis: review of 77 cases.

Peritoneal and ovarian endometriosis are anatomically highly polymorphous and can give rise to pain and sterility. Endometriosis can be recognized and evaluated by means of laparoscopy and an appropriate therapeutic strategy determined. Surgical laparoscopy using lasers (CO2, KTP and argon) produces excellent results. More than 80% of cases can be treated by coelioscopy, bearing in mind that severe endometriosis can require classic surgery and remains difficult to perform. However, one basic idea should not be forgotten, ie, that endometriosis is a progressive disease. Restoration of anatomic pelvic integrity (with free pouch of Douglas, mobility of appendages and functional ovaries) is the only guarantee of good fertility, achievable by interruption of progression of the disease. Following therapeutic trials with danazol, norsteroidal progestagens, gonadotrophin-releasing hormone agonists have opened up wide perspectives for use and we use them in combination with coeliac surgery. Our experience has paralleled that of Donnez and Bruhat, with almost identical results.

Combined Modality Therapy

Gonadotrophin-releasing hormone agonist and laparoscopic myomectomy.

The indications for operative laparoscopy have expanded greatly over the past decades, as its many advantages over laparotomy have been recognized. We report our techniques and short-term results concerning myomectomy by laparoscopy. From January 1, 1990 to October 1, 1991, 147 intraperitoneal myomectomies were performed in 70 patients: 46 of 70 were treated preoperatively with a depot gonadotrophin-releasing hormone agonist. No complications were observed. In selected cases, with the advantages of laparoscopic surgery, laparoscopic myomectomy appears to be a safe technique.

[Tuboperitoneal sterility. Indications, operative techniques and results of adhesiolysis and distal tuboplasties].

Major advances in the field of laparoscopic surgery have made it possible to perform most of the adnexal repair procedures by this route. The most common operation is adhesiolysis, i.e. the excision, usually with scissors, of peritubal and ovarian adhesions. This is a rapid, simple and non-traumatic technique. In salpingostomy, the hydrosalpinx is opened at its terminal end and the gauntlet cuff eversion of the newly created infundibulum is maintained by means of defocalized CO2 laser shots or electrocoagulation. The results of laparoscopic adhesiolysis and salpingostomy are very similar to those obtained with the conventional laparotomy and microsurgery techniques. These results, plus the advantages of laparoscopy (comfort of the patient, shorter stay in hospital, absence of scars), explain why operative laparoscopy is increasingly used in the treatment of operable adhesions and distal tubal lesions. In severe lesion, there is no alternative to in vitro fertilization.

Risk factors for ectopic pregnancy in 556 pregnancies after in vitro fertilization: implications for preventive management.

OBJECTIVE: To analyze risk factors for ectopic pregnancy (EP) after in vitro fertilization (IVF). DESIGN: A retrospective study of IVF pregnancies was performed between November 1983 and December 1989. SETTING: This study was conducted in a tertiary care center, the Port-Royal University Hospital. PATIENTS: Patients' records were reviewed for 48 EP and 508 intrauterine pregnancies obtained by IVF. INTERVENTIONS: Forty-six salpingectomies were performed for EP after IVF. MAIN OUTCOME MEASURE: We evaluated the impact on the ectopic rate of tubal status, the type of ovarian stimulation and luteal phase support, and the number of embryos transferred. RESULTS: Forty-three of 48 EP occurred in patients with tubal infertility. The rate of EP was significantly higher when the indication was tubal (11.1%) than when it was endometriosis (2.1%) or unexplained infertility (3.4%). Pathological findings revealed tubal lesions in all 46 salpingectomies. CONCLUSIONS: Ectopic pregnancy after IVF appears related to pre-existing tubal pathology. However, routine prophylactic salpingectomy to prevent the risk of EP does not appear justified.

Myomectomy by laparoscopy: a preliminary report of 43 cases.

OBJECTIVE: To evaluate the technique and short-term results of intraperitoneal (IP) myomectomies. DESIGN: From January 1, 1990, to March 1, 1991, IP myomectomies were performed in all cases in which it appeared feasible. SETTING: This study was conducted in a tertiary care center, the Port-Royal University Hospital. PATIENTS, PARTICIPANTS: Among 49 consecutive patients with interstitial or subserous myomas, 6 patients with voluminous, multiple myomas had laparotomies. Intraperitoneal myomectomy was performed in 43 patients. The indication for laparoscopy was a pelvic mass in 29 cases, infertility in 13, and severe endometriosis in 1 case. INTERVENTIONS: Thermocoagulation or monopolar coagulation was used for the uterine incision. Myometrium and serosa were sutured in 23 of 43 patients. Myomas were removed through the suprapubic puncture site after fragmentation of large myomas. MAIN OUTCOME MEASURE(S): We evaluated the length of the procedures, blood loss, and postoperative course. RESULTS: Ninety-two myomas were removed laparoscopically. No complication was observed. CONCLUSIONS: In selected cases, IP myomectomy appears to be a safe technique with the advantages of laparoscopic surgery.

[Surgical treatment of endometriosis].

The surgical treatment of endometriosis, which used to be performed by laparotomy, is now in most cases performed by coelioscopy. The purpose of surgery is to destroy or remove as much as possible of the endometriotic lesions and to treat their sequelae, usually adhesions. In the majority of patients, the coelioscopic treatment can be carried out at the same as the initial diagnostic coelioscopy, the stay in hospital not exceeding 48 hours. The pregnancy rate obtained is similar to that reported with laparotomy, but the operator must have a long experience of operative coelioscopy.

Reproductive outcome after laparoscopic salpingectomy for tubal pregnancy.

Since 1983, we have performed laparoscopic salpingectomy as a routine procedure for ectopic pregnancy (EP) in cases where conservative management is impossible or contraindicated. The main indications are a ruptured tubal gestation, a pathological tube, a history of tuboplasty, and an ipsilateral recurrence. This technique is simple, quick, and safe. Reproductive outcome after laparoscopic total salpingectomy for EP was evaluated in 125 cases between January 1983 and December 1987. The pregnancy rate was 33.6%. In our population, there was a high proportion of patients with a pathological or absent contralateral tube (74.4%). In patients with a normal contralateral tube (32 cases), the live birth rate (46.9%) was greater but not significantly than in patients (39 cases) with a patent but pathological tube (25.6%). In vitro fertilization (IVF) was performed in 59 patients; clinical pregnancy was obtained in 40.7% of cases. These encouraging results lead us rapidly to consider IVF in patients with a pathological contralateral tube.
