[Analysis of relevant factors for recurrence of ovarian endometriosis after conservative laparoscopic surgery]

OBJECTIVE: To analyze relevant factors for recurrence of ovarian endometriosis after conservative surgery. METHODS: A cohort study was performed on 310 patients who had performed conservative surgery for ovarian endometriosis. All patients underwent clinical interview. The relevant factors included: age at surgery, clinical symptom and signs, medical history, gynecologic examination, preoperative gravidity, complication, adenomyosis, American Society for Reproductive Medicine (ASRM) scores, post-operative drug therapy, post-operative gravidity and so on. The logistic regression analysis was performed to determine the predictive factors for recurrence of endometriosis. RESULTS: The relevant factors by univariate analysis were determined. The history of endometriosis surgery, history of intrauterine operation, tenderness nodule at cal-de-sal, bilateral endometrioma, multilocular cyst, intraoperative ASRM scores, complication of adenomyosis and operation time were the risk factors; whereas pre- and post-operative gravidity, post-operative drug therapy, and age at surgery were the protective factors. Meanwhile, the relevant factors by multivariate analysis were also confirmed. The history of endometriosis surgery, history of intrauterine operation, tenderness nodule at cal-de-sal, bilateral endometrioma, multilocular cyst, and intraoperative ASRM scores were the risk factors; whereas post-operative gravidity, post-operative drug therapy, pre-operative gravidity, and age at surgery were the protective factors. CONCLUSION: The risk factors for recurrence of ovarian endometriosis are history of endometriosis surgery, history of intrauterine operation, tenderness nodule at cal-de-sal, bilateral endometrioma, multilocular cyst, intraoperative ASRM scores, whereas the protective factors are pre- and post-operative gravidity, post-operative drug therapy and age at surgery.
