Fertility after colorectal resection for endometriosis: results of a prospective study comparing laparoscopy with open surgery.

摘要

OBJECTIVE: To determine whether the surgical route of colorectal resection for endometriosis is a determinant factor for fertility. DESIGN: Prospective study. SETTING: Tertiary-care university hospital. PATIENT(S): Fifty-two patients with endometriosis were randomly assigned to laparoscopic or open surgery. INTERVENTION(S): Laparoscopically assisted vs. open colorectal resection. MAIN OUTCOME MEASURE(S): Evaluation of fertility outcomes spontaneously and after assisted reproductive therapy. RESULT(S): The mean follow-up was 29 months. Among the 28 patients wishing to conceive, 11 (39.3%) became pregnant. Overall cumulative pregnancy rate at 52 months for these patients was 45.1%. For patients with or without infertility, the cumulative pregnancy rate was 37.6% and 55.6%, respectively, and the cumulative spontaneous pregnancy rate 13.3% and 36.5%, respectively. All the spontaneous pregnancies were observed in the laparoscopy group. CONCLUSION(S): This study demonstrates that spontaneous pregnancy is more frequent after laparoscopy compared with open surgery for colorectal endometriosis.
