Comparison of interval and postabortal/puerperal laparoscopic sterilization with the tubal ring procedure.

During a 5-year period, 344 women underwent laparoscopic sterilization with the tubal ring. Complications and failure rates were compared in intervals and postabortal/puerperal procedures. Only 9% were lost to follow-up, and 50% underwent a hysterosalpingoghraphy (HSG). The comparison of interval and postabortal/puerperal procedures showed no significant differences in complication rates, but postabortal/puerperal laparoscopy had a significantly lower failure rate than interval procedures (p less than 0.01). It was found that women whose laparoscopy was carried out despite peroperative complications had a significantly higher risk of sterilization failure (p less than 0.005). It is concluded that postabortal/puerperal laparoscopic sterilization with the tubal ring procedure is as safe as interval sterilization, and it is strongly recommended that peroperative complications with tubal ring sterilization should result in a reversion of the laparoscopy to a laparotomy and, if not, that the women be referred for HSG.

Late sequelae following laparoscopic sterilization employing electrocoagulation and tubal ring techniques: a comparative study.

Data on 211 consecutive laparoscopic sterilized women were compared. Half the patients were sterilized using unipolar electrocoagulation and the rest had tubal rings. The period of observation was 21-50 months, median 36.5 months. Four failures were observed, median 15 months after the operation. Pregnancy rates were 0.32 per 100 woman years using electrocoagulation and 1.02 using tubal rings. A total of 11% had experienced low abdominal pain and 4% dyspareunia. Menstrual pattern changes were reported by 31% in the electrocoagulation group and 43% in the tubal ring group. The rates of late sequelae were statistically significant independent of the technique employed.

[Laparoscopic sterilization with electrocautery: complications and reliability (author's transl)].

1084 laparoscopic sterilizations were evaluated in a retrospective study at the Universitäts-Frauenklinik Zürich. The operative and early postoperative complications and the reliability of the method were analysed and compared to the results in the literature. Based on a cumulative statistical analysis 0,5% intraoperative complications required laparotomy, the main indications being haemorrhages and bowel injuries. Failed attempts were encountered in one of 150 patients, the main causes of which were adhaesions and difficulties at establishing pneumoperitoneum. The failure rate of the laparoscopic electrocoagulation of the fallopian tube after a long-term follow-up was about 0,5%, 20--25% of these were ectopic pregnancies. The transection of the fallopian tubes did not diminish the pregnancy rate, but the risk of bleeding was considerably higher with this technic. Concurrently performed therapeutic abortion or preceeeding laparotomy did not increase the operative complication rate.

Luteal phase pregnancies in female sterilization patients.

Little is known of the incidence, predictors or outcomes of luteal phase pregnancies (LPPs) in women presenting for voluntary interval female sterilization. A series of 37 LPPs was identified from a large multicenter female sterilization data set. Each LPP case was matched with two nonpregnant (NP) controls for clinic, operator, surgical approach, tubal occlusion technique and date of surgery. The LPP cases did not have a distinct demographic or clinical profile, but were generally more fecund than NP controls. LPPs were further compared with a second unmatched group consisting of 123 true sterilization failures (TSFs), pregnancies conceived after sterilization. Women with LPPs were more likely to have their pregnancies confirmed and/or terminated in the second trimester than were women with TSFs. The majority of LPPs were carried to term; the majority of TSFs ended in induced abortion. There were 12 ruptured ectopic pregnancies among the TSFs and none among the LPPs. Programmatic implications of the results are discussed.

Intra-uterine device failure: relation with drug use.

A case-control study was undertaken in order to test the relationship between commonly used anti-inflammatory agents and the efficacy of intra-uterine devices (IUDs). Women who had become pregnant while wearing an IUD were compared with non-pregnant IUD users. 717 cases and 717 controls were recruited from the same medical practices. The case-women (IUD failure) used anti-inflammatory drugs, particularly aspirin, more frequently than the controls (p less than 0.001). In contrast, oral progestins, taken in the second part of the cycle (16th to 25th day) were more frequently used by the control-women group (p less than 0.001). Although cases and controls differed in age and gravidity (younger and higher, respectively) standardization for these items did not change the findings for drug use.

[Liability for unsuccessful sterilization?].

In 1980 the Bundesgerichtshof (German Federal Supreme Court) handed down two leading decisions. In both cases the doctor who was responsible for the failure of a sterilisation was sentenced to pay the parents' damages incurred by the support for the unwanted child. Doctors and lawyers have vehemently criticised these decisions. Recently these decisions were consciously ignored by the Frankfurt Regional Court of Appeal which decided, in a new case, that "a child can not be considered a damage" and, therefore, has rejected the claims of the parents, disappointed at the birth of their child. The reluctant mother's claim for immaterial damages was also rejected. The author's arguments also support a change of the Supreme Court's decision.

The snare method of laparoscopic sterilization: an analysis of 1,000 cases with 4 failures.

The snare method has proven to be an effective method of tubal resection for sterilization. In the most experienced hands, significant complications are indeed rare. However, the failure rate appears to be higher than that of the coagulation-alone method, at least in the postabortal patient. The necessity for pathologic confirmation, a tradition of surgery, is critically questioned. Additional coagulation of the tubal ends after resection is now recommended, especially in the patient seeking abortion as well as sterilization. The authors await the comparative long-term results of bipolar forceps and the newer mechanical methods of laparoscopic tubal sterilization. It is conceivable that the snare and other unipolar electrosurgical instruments designed for female sterilization will become obsolete.

[The effectiveness of different methods of laparoscopic tubal sterilization (author's transl)].

If sterilization is offered today to a young multipara pointing out the possibility of eventual later recanalization the most essential point lies in thorough patient information. The patient must be informed that less aggressive techniques like thermocoagulation or mechanical tubal occlusion bear a higher risk of failure and consequently eventual pregnancy 2%-4%-7%. Such failures are part of the method and must and cannot be considered malpractice. Extensive patient information about all pros and cons is the only way to avoid future problems. Spontaneous tubal recanalization has occurred and may occur to the most skilled surgeon. After twenty years of personal experience with almost all methods of laparoscopic tubal sterilization my recommendation today is: bipolar sterilization on one site of the isthmical tubal portion with division of the coagulated tissue. Even so sufficient tubal tissue should remain intact to allow eventual later recanalization. We were never disappointed with this way of proceeding and so far, contrary to all other methods, have observed no pregnancy among our patients.

The lack of interaction between temafloxacin and combined oral contraceptive steroids.

In view of the considerable debate concerning the possible failure of contraception in women taking broad spectrum antibiotics, we have examined a group of 12 women aged 22-32 in a controlled study. Each woman had been on long-term therapy with oral contraceptive steroids (OCS) containing ethynylestradiol (EE2) and levonorgestrel (Ng) for at least 6 months and all were in good general health. Blood samples were taken about 11.0 hours after dosing with their OCS on days 5, 6, 7 and 8 of their contraceptive cycle, for measurement of EE2, Ng, FSH and LH by radioimmunoassay. In addition blood samples were taken on days 19, 20 and 21 of the contraceptive cycle for assay of progesterone concentrations in plasma. The study was repeated in the next cycle of use of their OCS during which they took temafloxacin, a broad spectrum quinolone antibiotic in a dose of 600 mg twice daily for 7 days starting on day 1 of the cycle. All women completed the study satisfactorily as judged by diary cards, tablet counts and plasma temafloxacin concentrations. In the early part of the study some nausea and headaches were seen due to taking temafloxacin on an empty stomach but these effects were not seen when the antibiotic was later given with food. There was no evidence of any interaction between temafloxacin and the OCS. The plasma concentration of EE2 was 61.4 +/- 21.1 pg/ml in the control cycle and 68.5 +/- 26.6 pg/ml in the temafloxacin cycle.(ABSTRACT TRUNCATED AT 250 WORDS)

Morphology of Fallopian tubes removed from a patient after failure of clip sterilization.

A bilateral salpingectomy was performed at the time of vaginal hysterectomy in a pregnant patient sterilized 20 months earlier by application of Bleier clips to the fallopian tubes. Clip application to the left tube had been incomplete. Undisturbed tissue (left tube) and clipped tissue (right tube) were examined and compared by light and scanning electron microscopy. The segment of tube fully grasped by the clip had a completely detached lining epithelium with coarse and flattened mucosa, a loose stroma, and disorganized muscular bundles. The left tubal mucosa was normal, whereas the right tube was stenosed at the site of clip placement, with rigid walls and a 0.175 mm luminal diameter. With progressively greater stenosis toward the clip site, mucosal destruction increased. Polypoidal mucosal folds were seen, as well as fibrous adhesions between mucosal folds. These observations indicate that tissue damage is extensive enough after clip application to require excision of the damaged segment of tube and microsurgical re-anastomosis for reversal of sterilization.

Long-term follow-up of laparoscopic sterilizations by electrocoagulation, the Hulka clip and the tubal ring.

A follow-up study of 499 women who underwent sterilization between August 1973 and May 1976 at the Siriraj Hospital in Bangkok, Thailand, and had long-term (4-12 years post-surgery) follow-up is described. Women were sterilized through participation in one of three studies conducted at this hospital. In the first study, 124 underwent sterilization using the Hulka clip via laparoscopy; 67.7% of these women returned for a long-term follow-up visit. In the second study, 300 women were randomly allocated to the Hulka clip or to unipolar electrocoagulation (cautery) via laparoscopy; 70.7% of the women from this study returned for a long-term follow-up visit. The final study was a randomized trial comparing the tubal ring and unipolar electrocoagulation occlusion techniques in 300 cases. Long-term follow-up visits were recorded for 207 women (69.0%) from this study. Five technical failures (procedures not performed or completed as planned) and six non-interval cases were excluded from follow-up analyses. A total of 713 interval patients were eligible for follow-up. Long-term follow-up was initiated in 1978 and continued through 1986. Late sequelae of sterilization, including pregnancies and pelvic surgery, are discussed with regard to type and time of tubal occlusion. One intrauterine and two ectopic pregnancies were reported among women who were sterilized with cautery; one ectopic pregnancy was reported by a woman sterilized with the Hulka clip. Pelvic or abdominal surgeries were reported in 27 cases. Most (greater than 98%) women indicated that they were satisfied with their sterilization procedure.

A comparison of different laparoscopic sterilization occlusion techniques in 24,439 procedures.

This investigation assessed the safety and efficacy of five laparoscopic tubal occlusion techniques for female sterilization: electrocoagulation, the tubal ring via conventional and open laparoscopy, the prototype spring-loaded clip, and the Rocket clip. The 24,439 cases make up a data set collected by collaborating staffs at 64 institutions in 27 countries. The five techniques were compared with respect to six commonly evaluated parameters. Rates of surgical difficulties ranged from 2.4% to 12.5% (5.1% overall); rates of surgical complications, from 0.7% to 2.7% (1.7% overall); and rates of technical failures, from 0.6% to 1.0% (0.8% overall). Twelve-month life-table pregnancy rates were less than one per 100 women years. Prospective data on six menstrual parameters revealed that the menstrual cycles of the majority of women were unchanged after sterilization; for those who reported a change, approximately half experienced a change in one direction and half in the other direction. For example, one half reported an increase in the amount of menstrual flow, and one half reported a decrease in the amount of flow. The reported incidence of subsequent pelvic operations was less than 1% at each long-term follow-up. These data indicate that laparoscopic sterilization is safe and effective and that none of the studied techniques has a distinct advantage.

Evaluation of contemporary female sterilization methods.

Different methods of sterilization were evaluated. Laparoscopic techniques were the most satisfactory because they had lower pelvic and incision infection rates and shorter hospitalization and convalescent times than laparotomy lower pelvic infection rates than culdoscopy and culpotomy. Via laparoscopy, sterilization by coagulation and cutting, spring-loaded clips and bands was an effective, safe method. Mechanical problems with the applicator and optics and decreased visibility resulted in more technical failures and difficulties and more misapplication with the clip applicator. Although the total complication rates were similar with all methods, bleeding from the tubes and wound and pelvic infections were more frequent with silastic-band technique. Long-term complications, such as dysmenorrhea and menometrorrhagia and especially those resulting in hysterectomy after laparoscopy, are infrequent. Pregnancy rates are low after laparoscopic sterilization with coagulation and silastic bands as compared to the clip. Rates of complications with sterilization combined with abortion or delivery are only slightly higher than after abortion without sterilization and much less than the combined complications that would be anticipated from abortion and interval sterilization. To make colpotomy, culdoscopy and minilaparotomy easier and potentially safer, mechanical techniques using the spring-loaded clip and silastic band are being evaluated. Simplified techniques that can be administered via the cervix, such as Quinacrine, may be practical in the future.

[Surgical procedures for sterilization of the women: certainty--complications (author's transl)].

The time (interval, postpartum, postabortum), location (uterus, mucus membrane of the oviducts, tubes), access (transcervical, transvaginal, trans-abdominal) and the actual method of sterilization for the women (surgical, electric, thermic, mechanical) can be differentiated and combined with each other in various ways. Today the usual procedure is sterilization by partial resection of the oviducts performed laparoscopically in the interval via electrocoagulation and surgically after delivery via periumbilical minilaparotomy. Laparoscopic sterilization via electrocoagulation has a rate of failure of about 1:1,000 and the mortality rate is less than 1:10,000. The most frequent complications are: hemorrhages due to injury of the larger vessels and burns in the intestine caused by the electric current. For this reason, conventional (:unipolar") electrocoagulation should be replaced by the so-called bipolar coagulation or other newer methods which avoid these complications. On the basis of the current literature, no definitive statements can be made regarding the reliability of the newer methods (silastic ring, plastic clips, thermocoagulation). An additional, although up until now purely hypothetic, advantage of the newer methods is the possibility of reversibility. With conventional electrocoagulation, the rate of reversilbility is very low. Additional alternatives are also culdotomy and minilaparotomy in the interval with the assistance of a uterus elevator. Both ways of access may be combined with various methods of sterilization. The pros and cons of the hysterectomy as a method of sterilization are still being discussed. Occasional late sequelae of sterilization such as menstrual disorders, pain and, particularly, problems related to sexual intercourse have only recently come to light. They have not yet been adequately investigated.

Fertilisation and implantation failure in an oral contraceptive user.

We report the case of a young woman taking a low-dose oral contraceptive (gestodene 0.075mg and ethinylestradiol 0.02mg) in whom we documented by both hormonal assays and sonographic evaluations the occurrence of ovulation, oocyte fertilization and embryo implantation. However, the implantation process did not complete and only a biochemical pregnancy was registered. On the basis of known actions of estroprogestin on endometrium that are not conducive to implantation, it is possible that the pregnancy loss was originated by oral contraceptive's hormonal influence at endometrial level.
