Pregnancy rates following tubal anastomosis: Pomeroy partial salpingectomy versus electrocautery.

Eighty-six tubal anastomosis patients were analyzed for successful outcome. Controlling for tubal length, we analyzed a number of possible confounding variables for their effects on pregnancy, including the type of sterilization performed. Results indicated term pregnancies in 63.9% of all patients, with no significant effect seen due to type of sterilization procedure. Monthly fecundity rates and life table analysis similarly demonstrated no significant differences between the two sterilization groups. With the use of multiple logistic regression, only age proved to be a significant predictor of pregnancy (p = 0.008). Type of sterilization as well as other tested variables had no demonstrable effect. We conclude that with careful initial selection of patients, exclusion of women without an anastomosed tube 4 cm or longer, and meticulous surgical technique, successful pregnancy rates higher than those generally quoted can be achieved.
