Laparoscopic segmental colorectal resection for endometriosis: limits and complications

Deep pelvic endometriosis with colorectal involvement is a complex disorder often requiring segmental bowel resection. This study investigated the limits and complications of laparoscopic segmental colorectal resection.

Laparoscopic segmental colorectal resection was performed for 71 women with bowel endometriosis. Intra- and postoperative complications were evaluated, together with symptom outcomes, by means of questionnaires completed before and after surgery. Surgical procedures and complications were compared between the first part of the study (40 cases, previously published) and the second part (31 cases).

Of the 71 women, 64 (90%) underwent laparoscopic segmental colorectal resection, with 7 requiring laparoconversion. Major complications occurred in nine cases (12.6%), six with rectovaginal fistulae and three with pelvic abscesses. The mean operating time decreased significantly during the study (p < 0.05). The mean follow-up period after colorectal resection was 24.4 +/- 2.2 months. No differences in the rates of laparoconversion or complications were observed between the two periods, whereas major associated surgical procedures were more frequent during the second period. Dysmenorrhea (p < 0.0001), dyspareunia (p = 0.0001), pain at defecation (p = 0.0004), bowel movement pain or cramping (p < 0.0001), lower back pain (p < 0.0001), and asthenia (p < 0.0001) were improved after the operation, with no difference between the study periods.

This large series confirms the feasibility and efficacy of laparoscopic segmental colorectal resection. However, women must be informed of the risk for potentially severe complications.
