Microsurgical tubal desterilization: an efficient procedure. Evaluation of a 42 cases cohort according to Guzick's biparametric method

摘要

OBJECTIVE: Tubal ligation tends to be a contraceptive method used by younger women. Regrets may then become more frequent. Although less tough today, microsurgical tubal reversal is a reliable technique and we report results taking into account exposure time and curing rate. PATIENTS AND METHODS: We studied 42 cases operated from 1990 and 1997. The patients were selected following the same protocol and operated according to the same surgical way. The results were analyzed by Guzick biparametric method, and comparison assessed by Log-rank test. We compared results depending on age, type of sterilization (mechanical and non mechanical), duration of laparotomic time, and interval between sterilization and reversal. RESULTS: There is an overall hope of 80% of pregnancy at 49 months. Even if there is no statistical difference between the different parameters studied, there is a trend to better reversal results after mechanical sterilization and intervention duration less than 90 minutes. DISCUSSION AND CONCLUSION: Microsurgical tubal reversal is a trustworthy technique, which may be offered to patients regretting their sterilization. Analyzing results by Guzick method is interesting, but insufficiently used although more precise to express a curing (= pregnancy) result than a simple Kaplan-Meier surviving curve. Microsurgical reversal may be proposed to carefully selected patients, even after 40 years.
