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.
