OBJECTIVE: To assess the effect of surgeon's increasing experience in conservative laparoscopic surgery of women with rectovaginal endometriosis on the surgical outcome of these patients recurrence rate.
DESIGN: Prospective cohort study.
SETTING: University teaching hospital.
PATIENT(S): The first 60 consecutive patients undergoing laparoscopic conservative surgery for symptomatic rectovaginal endometriosis at our institution during a 4- year period.
INTERVENTION(S): Cases were classified into two groups according to the date of the patient's operation: the first 30 cases were defined as the early cases and the subsequent 30 cases as the late cases.
MAIN OUTCOME MEASURE(S): Operating time, perioperative complications, and surgical outcome. Univariate and multivariate analyses for risk factors with recurrence of disease.
RESULT(S): The two groups were similar in patient characteristics. There was a reduction in the rate of laparoconversion, operating time, estimated amount of blood loss, cases with incomplete removal, and recurrence rate with increasing surgeon's experience. Surgical completeness was significantly associated with recurrence of disease.
CONCLUSION(S): A learning curve is demonstrated in the conservative laparoscopic management of patients with rectovaginal endometriosis. After gaining experience in performing 30 cases, the recurrence rate is significantly reduced.
