Comparison of Laparoscopic Discoid Resection and Segmental Resection for Colorectal Endometriosis Using a Propensity Score Matching Analysis.

STUDY OBJECTIVE: Our primary endpoint was to compare the intra- and postoperative complications, whereas secondary endpoints were the occurrence of voiding dysfunction and evaluation of the quality or life of segmental and discoid resection in patients with colorectal endometriosis.

DESIGN: Retrospective study (Canadian Task Force classification II-2).

SETTING: Tenon University Hospital in Paris.

PATIENTS: Thirty-one 31 patients who underwent a conservative surgery and 31 patients who underwent.

INTERVENTIONS: The 2 groups were compared using propensity score matching (PSM) analysis, with a median follow-up of 247 days (8.2 months).

MEASUREMENTS AND MAIN RESULTS: Discoid colorectal resection was associated with a shorter operating time (155 vs 180 minutes, p = .03) and hospital stay (7 vs 8 days, p = .002) than segmental colorectal resection; however, a similar intra- and postoperative complication rate was found. A higher rate of postoperative voiding dysfunction was observed in the segmental resection group (19% vs 45%, p = .03) as well as duration of voiding dysfunction requiring bladder self-catheterization longer than 30 days (0 vs 22%, p = .005).

CONCLUSION: Our PSM analysis suggests the advantages of discoid resection because it results in a similar surgical complication rate to segmental resection but with advantages in operating time, hospital stay, and voiding dysfunction.
