Robotically assisted laparoscopic microsurgical tubal reanastomosis: a retrospective study

ObjectiveTo evaluate the pregnancy and delivery outcome of robot-assisted tubal reanastomosis.DesignRetrospective cohort study.SettingUniversity hospital.Patient(s)Ninety-seven patients with available follow-up who underwent the reversal of tubal ligation, with a median age of 37 years (range, 24–47 years).Intervention(s)Tubal reanastomosis by robot-assisted laparoscopy.Main Outcome Measure(s)Analysis of the distribution of time to conception and to estimate the crude pregnancy and birth rates at 2 years.Result(s)The overall pregnancy and birth rates were 71%, (95% confidence interval [CI], 61%–80%) and 62% (95% CI, 52%–72%). Ninety-one percent (95% CI, 76%–98%) of patients <35 years old became pregnant, and 88% (95% CI, 72%–97%) delivered at least once. The corresponding pregnancy and delivery rates were 75% (95% CI, 57%–89%) and 66% (95% CI, 47%–81%) between 36 and 39 years old, 50% (95% CI, 25%–75%) and 43.8% (95% CI, 20%–70%) between 40 and 42 years old, 33% (95% CI, 10%–65%) and 8.3% (95% CI, <1%–38%) after the age of 43 years.Conclusion(s)This study reports satisfactory birth rates after tubal reanastomosis by robot-assisted laparoscopy in patients aged 40 years or less.
