Correlative factors analysis of recurrence of endometriosis after conservative surgery

To determine the correlative factors with recurrence of endometriosis after conservative surgery. A cohort study was performed on 285 patients who had a minimum of 36 months of follow-up after conservative surgery for endometriosis. All patients underwent clinical interview, physical examination and ultrasonography. The factors measured included: age at surgery, age at onset of disease, gravidity, parity, tenderness nodule at cul-de-sac (yes/no), uterus mobility (movable/fixed), serum CA(125) level, type of operation (laparoscopy/laparotomy), history of operation for endometriosis (yes/no), side of endometrioma (left/right/bilateral), intraoperative revised classification American Fertility Society (r-AFS) scores, post-operative r-AFS scores, highest post-operative temperature, post-operative adjuvant therapy, post-operative gravidity and parity. The recurrent rate and its predictive factors were evaluated and the univariate, multivariate COX regression and Kaplan-Meier analyses were performed to determine th
