Sterilization failure, sterilization reversal, and pregnancy after sterilization reversal in Quebec.

OBJECTIVE: 1). To determine the likelihood of sterilization reversal and of subsequent sterilization after sterilization reversal among men and women and 2). to examine the likelihood of pregnancy after sterilization (contraceptive failure) and of pregnancy after sterilization reversal. METHODS: Payment data from the Quebec provincial health insurance system were obtained for each person undergoing vasectomy or female sterilization from January 1, 1980 to December 31, 1999 and linked through a unique identifying number for each person. Using standard techniques of survival analysis, we computed the cumulative probability of experiencing each of six events. RESULTS: Among women, 0.9% (of 311960) experienced a pregnancy after sterilization, 1.8% (of 321929) obtained a reversal after sterilization, 61% (of 4369) achieved a pregnancy after sterilization reversal and 48% achieved a delivery; 23% (of 4677) obtained a subsequent sterilization after reversal. Among men, 2.4% (of 310827) obtained a reversal after vasectomy and 18% (of 6694) obtained a subsequent vasectomy after reversal. All of these risks were much higher among those in the youngest age groups. CONCLUSION: Sterilization reversal and pregnancy after sterilization are not rare. Relatively high rates of reversal among the youngest age groups suggest a need for better counseling about alternative contraceptive strategies.

Sterilization reversal by macrosurgical tubal anastomosis.

A simple macrosurgical technique developed by the writer in 1974, and used specifically for the reversal of sterilization by tubal anastomosis, is presented. The technique has been employed where facilities have been no more sophisticated than those used for the original sterilization. In terms of intrauterine pregnancy, a success rate of 43% has been achieved from a series of 14 unselected patients who requested tubal reconstruction after sterilization. A plea is made for the employment of sterilizing techniques which cause minimal tubal damage, and thereby allow the greatest likelihood of success with any future reconstructive procedure.

Repeat sterilization reversal.

Thirteen women had repeat sterilization reversal using microsurgery either because of failed IVF or personal preference for microsurgery. Six pregnancies occurred in 5 women resulting in 5 livebirths and 1 miscarriage. Pregnancy occurred in all 3 patients having isthmic anastomosis in the second sterilization reversal. Preliminary hysteroscopic tubal cannulation would have excluded operation on 2 patients who had tubal blockage extending several centimetres proximal to the site of the first anastomosis.

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.

Sterilization reversal: results of 101 attempts.

One hundred one patients underwent reversal of sterilization. Among the 79 patients with a known outcome, the successful pregnancy rate was 35%. In contrast, the tubal patency rate was 91%. An analysis of standard preoperative fertility factors failed to reveal their predictive value. Total motile sperm counts of greater than 60 x 10(6) resulted in more successful pregnancies than counts below this number (p less than or equal to 0.005). The operating microscope did not have any advantage over loupes. Patients with one tube greater than 7 cm in length had a delivery rate of 75%, compared with 16% for those with shorter tubes (p less than or equal to 0.001). Eighty percent of patients with a distal segment of the anastomosis that included part of the isthmic tube had deliveries (p less than or equal to 0.029). In contrast, all ectopic pregnancies were associated with a distal segment consisting only of ampulla; the risk of ectopic pregnancy after patent ampullary anastomosis was 23% (p less than or equal to 0.05).

Follow-up of women seeking sterilization reversal: a Brazilian experience.

OBJECTIVE: To analyze the follow-up of a cohort of women who requested reversal of surgical sterilization. METHODS: This retrospective study was carried out at the State University of Campinas, Brazil. A cohort of 394 women who requested sterilization reversal was followed up for one year after reversal surgery. The analysis includes the percentage of women who completed the steps between the initial consultation up to one year after reversal surgery. RESULTS: After an initial consultation, 55.1% of the patients decided not to continue with the procedures. Of the patients who did undergo laparoscopy (n = 177), 48.6% had no possibility of a successful surgical reversal because the Fallopian tubes were in very poor condition. Only 17.5% of the initial patients requesting reversal ultimately underwent surgery and 3.3% became pregnant. CONCLUSIONS: The analysis of regret about surgical sterilization should include not only women who undergo surgery but also women requesting surgery. Better patient selection and counseling prior to sterilization are necessary in order to prevent increasing rates of sterilization regret in Brazil.

Microsurgical tubal anastomosis for sterilization reversal.

A series of patients requesting sterilization reversal has been reviewed. Microsurgical tubal anastomosis has been successfully employed and offers improved surgical results. Minimization of the length of tube damaged at sterilization procedures is probably a major factor in determining pregnancy rates should subsequent reversal be desired.

Reversible sterilization.

The present techniques for sterilization of women consist of different methods to block the passage through the oviducts. The disadvantage of all techniques is that the possiblity of restoring fertility is very limited. The aim of the present study is to demonstrate a method of sterilization which is reversible.

The role of laparoscopy in the evaluation of candidates for sterilization reversal.

An algorithm that avoids preliminary laparoscopy for sterilization reversal (SR) candidates with previous Pomeroy, loop, Hulka clip, Irving, and single-burn cautery tubal ligation techniques was used. Anastomosis was attempted only when it could be anticipated that the final length of at least one tube would be 3 cm or more. Of 259 SR candidates evaluated according to the algorithm, 235 had SR procedures. Seven of 185 patients (3.8%) who did not undergo laparoscopy were found to have inoperable tubes at laparotomy. Four of these patients had histories of a prior unilateral salpingectomy. The authors conclude that, given their criteria for proceeding with tubal anastomosis, laparoscopy can be avoided in properly selected SR candidates. The results also indicate that patients with a history of unilateral salpingectomy should undergo preliminary laparoscopy.

Fluoroscopically guided transcervical fallopian tube recanalization of post-sterilization reversal mid-tubal obstructions.

PURPOSE: To assess the technical success and early outcome of fluoroscopically guided transcervical fallopian tube recanalization (FTR) in mid-tubal occlusion following sterilization reversal surgery. METHODS: From July 1995 to January 1998, patients with greater than 12 months secondary infertility underwent hysterosalpingography (HSG). FTR was performed in proximal or mid-tubal occlusion. Cases of FTR in mid-tubal occlusion were included in this study. Technical success (defined as complete tubal patency) using a standard guidewire and hydrophilic glidewire, the number of patients with at least one patent tube, and the intrauterine and ectopic pregnancy rates were determined. RESULTS: Twenty-six infertile patients with previous sterilization reversal underwent HSG. Eight of 26 (31%) patients (mean age 32 years, range 23-37 years), had attempted FTR for mid-tubal occlusion at the site of surgical anastomosis. Fourteen tubes were attempted as there were two previous salpingectomies. Technical success was achieved in eight of 14 (57%) tubes attempted, resulting in five of eight (62%) patients having at least one patent tube. At follow-up (mean 18 months, range 12-28 months) in these five patients there was one intrauterine pregnancy. There were no ectopic pregnancies. CONCLUSIONS: FTR in mid-tubal obstruction in infertile patients following sterilization reversal surgery is technically feasible and may result in intrauterine pregnancy. In this small group there was a lower technical success rate and lower pregnancy rate than in unselected proximal tubal occlusion.

[Reversible sterilization with a physiological solution in the rat: preliminary note].

In this paper the Authors present a technique of reversible sterilization of female rats. They used saline hot solution through cervix and uterine horns in 45 S.D. female rats. They divided the rats in three groups. The first group received a 43 degree hydrotubation, the second a 50 degree hydrotubation and the third a 60 degree hydrotubation. All the animals were mated several times and the litter sizes were studied. Biopsies were taken by uterine horns and histological results are discussed.

Loupe microsurgical tubal sterilization reversal. Experience at a community-level naval hospital.

OBJECTIVE: To evaluate the success rates of loupe microsurgical tubal sterilization reversal procedures performed by a generalist obstetrician-gynecologist at a community-level naval hospital. STUDY DESIGN: Consecutive patients who underwent microsurgical tubal anastomosis under loupe magnification by the author during a 16-month period were subjected to a review for outcome in this case series report. RESULTS: Twenty-three patients who underwent reversal of tubal ligation by the author were examined for outcome. By 29 months after the last case studied, the overall conception rate was 78.3% and intrauterine pregnancy rate 68.6%. The miscarriage and ectopic rates were 13.0% and 8.7%, respectively. CONCLUSION: Loupe microsurgical tubal reversal by a properly trained generalist obstetrician-gynecologist at a community hospital rendered success rates comparable to those published in the literature.
