Long-term follow-up after conservative surgery for rectovaginal endometriosis

Objective The purpose of this study was to evaluate long-term results in patients who received conservative surgical treatment for rectovaginal endometriosis. Study design We analyzed the follow-up data for 83 women who underwent surgery for rectovaginal endometriosis. The inclusion criteria were age 20 to 42 years, moderate-to-severe pain symptoms, conservative treatment with retention of the uterus, and at least 1 ovary; the follow-up period was ≥12 months. Kaplan-Meier analysis and Cox regression were used to calculate recurrence rates. Results The cumulative rates of pain recurrence, clinical or sonographic recurrence, and new treatment were 28%, 34%, and 27%, respectively. The younger patients had the higher risk of recurrence. Pregnancy had protective effects against the recurrence of symptoms and a need for a new treatment. Patients who underwent bowel resection had fewer recurrences. Conclusion Segmental resection and anastomosis of the bowel, when necessary, improves the outcome without affecting chances of conception. Higher recurrence rates in younger patients seems to justify a more radical treatment in this group of women.
