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

Abstract

Study ObjectiveOur 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. DesignRetrospective study (Canadian Task Force classification II-2). SettingTenon University Hospital in Paris. PatientsThirty-one 31 patients who underwent a conservative surgery and 31 patients who underwent. InterventionsThe 2 groups were compared using propensity score matching (PSM) analysis, with a median follow-up of 247 days (8.2 months). Measurements and Main ResultsDiscoid 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). ConclusionOur 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.
