Abstract

STUDY OBJECTIVE: To compare postoperative complications and rectovaginal fistula rate in women undergoing excision of large rectovaginal endometriosis requiring concomitant excision of rectum and vagina during 2 time periods with differing policies for preventive stoma confection. DESIGN: Retrospective before-and-after comparative cohort study on data prospectively recorded in a database. Patients managed from September 2018 to March 2020 (first period) were compared with those managed from April 2020 to June 2022 (second period). SETTING: Endometriosis Institute. PATIENTS: One hundred sixty-eight patients presenting with deep endometriosis infiltrating the rectum and vagina, with lesions more than 3 cm in diameter during 2 consecutive time periods with differing policies regarding use of preventive stoma. INTERVENTIONS: Rectal disc excision or colorectal resection, concomitantly with large vaginal excision. MEASUREMENTS AND MAIN RESULTS: A total of 87 and 81 women received surgery during the first and the second period, respectively, during which the rate of preventive stoma was, respectively, 32.2% and 8.6%. Deep rectovaginal nodule characteristics were comparable. The mean height (SD) of rectal sutures after disc excision and colorectal resection were, respectively, 6.5 cm (2.3 cm) and 7.2 cm (3.8 cm). Rectovaginal fistula was recorded in 17 patients, corresponding to an overall rate of 10.1%. The rates of rectovaginal fistula in the group of patients with and without preventive stoma, regardless of the period in which surgery was performed, were 11.4% and 9.8%, respectively (p = .76). The rates of fistula recorded during the first and the second period were, respectively, 9.2% and 11.1% (p = .80), and that of overall early main complications were 31% and 29.6% (p = .84). Regression logistic model identified an independent relationship between smoking and rectovaginal fistula (adjusted odds ratio [OR] 3.9, 95% confidence interval [CI] 1.1-14) after adjustment for the period (adjusted OR 1.4, 95% CI 0.4-4.9 related to the second period), stoma confection (adjusted OR 1.8, 95% CI 0.5-7.1 related to stoma confection), robotic surgery (adjusted OR 1.7, 95% CI 0.3-10.1 related to robotic assistance), and type of rectal surgery (adjusted OR 0.4, 95% CI 0.1-1.4 related to disc excision when compared with colorectal resection). CONCLUSION: No statistically significant differences were found concerning risk of rectovaginal fistula in women with rectovaginal endometriosis requiring large rectal and vaginal excision after a decision to no longer routinely perform preventive stoma.
