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.

Terminal tuboplasties by laparoscopy: 65 consecutive cases.

A series of 65 consecutive laparoscopic distal tuboplasties, performed from May 1986 to May 1988 is reported. Thirty-one were fimbrioplasties and 34 were neosalpingostomies. Outcome was evaluated at 18 months postoperatively. Twenty-two patients obtained pregnancies (33.8%), of which 18 were intrauterine (27.7%). The intrauterine pregnancy rate was 25.8% after fimbrioplasty and 29.4% after neosalpingostomy. These results are comparable with those obtained after microsurgery. Progress in operative laparoscopy may be attributed to the development of an appropriate atraumatic instrumentation and the CO2 laser. The major advantage of laparoscopic techniques is their availability at the time of diagnostic laparoscopy. Immediate opening of hydrosalpinges allows for precise evaluation of the tubal mucosa, thereby establishing prognosis. In cases with a severely altered mucosa, in vitro fertilization may be considered immediately. When the mucosa is satisfactory, laparoscopic fimbrioplasty or neosalpingostomy may be performed. Within 1 year after one of these procedures, a pregnancy is generally achieved in 1 of 3 patients.

Diagnosis and treatment of ectopic pregnancy by retrograde selective salpingography and intraluminal methotrexate injection: work in progress.

Selective retrograde trans-cervical salpingography was carried out in four patients in whom ectopic pregnancy was suspected. The Fallopian tube was catheterized using a catheter set designed in our centre. The 6F catheter was placed in the cornua and an inner coaxial catheter was easily introduced into the proximal portion of the Fallopian tube, guided by tactile impression. Contrast medium was then injected and a round haloed mass was seen. Thereafter, the Fallopian tube was catheterized using a metallic guidewire until its tip was adjacent to the ectopic pregnancy. The coaxial catheter was then advanced along the guidewire and after removal of the latter, 5-35 mg of methotrexate was injected into the Fallopian tube. This new procedure was simple, well tolerated and had no side effects. A tubal pregnancy was demonstrated and surgery was avoided in all cases.

In vitro fertilization without ovarian stimulation: a simplified protocol applied in 80 cycles.

Ovulation induction with various hormonal agents has become a standard component of in vitro fertilization (IVF) cycles to obtain multiple oocytes. Failure to anticipate the retrieval of more than two oocytes often results in cancellation of the cycle. In this study, we report our results in 80 unstimulated IVF cycles. Serum estradiol (E2) and pelvic ultra-sound monitoring were begun on day 9 of the cycle. Human chorionic gonadotropin (hCG) was administered when the E2 level exceeded 180 pg/mL and the dominant follicle was greater than 18 mm. Eighteen pregnancies were obtained (22.5%/cycle), and 14 (17.5%/cycle) are ongoing. We conclude that favorable results can be obtained from unstimulated IVF cycles, despite replacement of a single embryo.

[Nipple discharge without palpable tumor. Experience of the Institut Curie from 1970 to 1984].

Four hundred and ten women with serous or bleeding nipple discharge without palpable mass were treated by surgery in the Curie Institute between 1970 and 1984. The cancer rate in this group was 12.2 per cent. Galactography was of anatomical interest as it showed the canal at the origin of the discharge. Malignant cells were observed at cytological examination in only 17 per cent of intragalactophoric cancers. Surgical excision is necessary if the nipple discharge is uniporous and easily reproducible by areolar pressure, particularly in the post-menopausal period when the frequency of cancer is highest (17.7 per cent).

A new in vitro fertilization technique: intravaginal culture.

Intravaginal culture (IVC) is a new technique elaborated by the authors for the fertilization and culture of human oocytes. Its principle consists of fertilization and early development of the eggs in a closed, air-free milieu without the addition of CO2. One to five ovocytes are deposited in a tube completely filled with 3 ml of culture medium less than 1 hour after their recovery, with 10,000 to 20,000 spermatozoa per ml previously prepared. The tube is then hermetically closed and it is placed in the maternal vagina and held by a diaphragm for incubation for 44 to 50 hours. After this time, the content of the tube is examined and embryos are transferred to the uterus. In the first 100 consecutive punctures, 22 clinical pregnancies were obtained: 17 deliveries, 3 spontaneous abortions, and 2 tubal pregnancies. Also, a randomized study comparing IVC to in vitro fertilization (IVF) was done (160 cycles) and no statistically different cleavage, transfer, or pregnancy rate was seen between IVC and IVF. By simplifying the laboratory manipulations, this technique decreases the cost of IVF and permits its standardization and diffusion. It creates a psychologic comfort permitting active participation of the mother in this stage of embryo development. Also, the use of this technique may give greater knowledge of human gamete metabolism and of the physiology of reproduction.

[Intravaginal culture and embryo transfer].

The intra-vaginal culture and embryo transfer is based on the principle of fertilization of hyman ovocytes in the absence of CO2-enriched air. Ovocytes and spermatozoa are placed in a water-tight tube filled with B2 medium and placed in the vagina during the culture. Once the culture is done, the embryos are replaced in the uterus. The various studies done with intra-vaginal culture and embryo transfer, their results as well as future prospects are reviewed in detail.

Experimental study of CO2-laser-induced histological effects on human fallopian tube: determination of CO2 laser parameters to be used in microsurgery.

This experiment investigates CO2-laser-induced histological effects on fallopian tubes obtained during hysterectomies in women. Tubal transversal sections were performed at isthmic and ampullar sites. Forty strips were available for histological study of the cut section area. The role of different parameters such as radiation power and beam fractionation (continuous versus pulsed) on tissue lesions was assessed. In tubal microsurgery, the CO2 laser can be used as a scalpel with the predominant advantage of minimal tissular alterations. As a result of this study, our recommended parameters are the following: radiation power, 7-10 W; beam focalization zone, 0.2 mm; energy density, 20,000-35,000 W/cm2; continuous operation; moving speed, 1 cm/s.

[Intravaginal culture and embryo transfer. A new method for the fertilization of human oocytes].

This technique was developed at the University Clinic of Port-Royal. It corresponds to the intravaginal culture of embryos and their transfer into the uterus. After ovocyte stimulation, most often by Clomid HMG, the follicles are aspirated under laparoscopic or sonographic control 34 to 36 hours after HCG. After being collected, the ovocytes are placed, whatever their stage of maturity, in one or several 3 ml tubes completely filled with culture medium (B2 of pure Menezo). Up to 4 ovocytes per tube are thus fertilized with 10 to 20,000 mobile spermatozoids/ml, prepared in the usual dilution, centrifugation and migration. Then the tube(s) are placed in the posterior vaginal cul-de-sac, kept in place with a diaphragm where they will remain during the 44 to 48 hours of culture time. Following that time, the contents of the tube are examined in order to evaluate the occurrence and the stage of embryonic division. A first series of 100 aspirations has enabled to obtain 15 pregnancies, still evolving, including two births of healthy children. A randomized series is currently in progress to determine a possible difference in the rates of pregnancy between CIVETE and the classic technique. Beside its new psychological contribution, this technique has demonstrated that it was possible to culture human embryos in the absence of CO2; its extreme simplicity should lead to a broader expansion of this technique.
