Abstract:

Objective: To investigate the influencing factors for recurrence after laparoscopic conservative surgery in patients with stage Ⅲ-Ⅳ endometriosis and provide evidence for making personal treatment plans. Methods: A total of 538 patients with stage Ⅲ-Ⅳ endometriosis who underwent laparoscopic conservative surgery in the Provincial Hospital Affiliated to Anhui Medical University from January 2016 to January 2019 were selected as study subjects. Combined with clinical data and follow-up information, SPSS 26.0 software was used to analyze the factors affecting postoperative recurrence and postoperative pregnancy. Results: In this study, the postoperative follow-up time of all patients was 16-53 months, and the median follow-up time was 35.1 months, a total of 77 cases recurred during this period. Univariate analysis showed that r-AFS scores, preoperative dysmenorrhea, postoperative GnRHa treatment time and postoperative pregnancy can affect the recurrence after stage Ⅲ-Ⅳ endometriosis surgery (P<0.05). Multivariate Cox regression analysis showed that dysmenorrhea and r-AFS scores≥77.5 were independent risk factors for postoperative recurrence of ovarian endometriosis (P<0.05). Postoperative GnRHa treatment for 6 months and postoperative pregnancy were protective factors for postoperative recurrence (P<0.05). Compared with the natural pregnancy rate in the second year(27.27%) and the third year(18.75%) after surgery,the pregnancy rate in the first year after surgery was the highest (45.9%),and the difference was statistically significant (P<0.0167). Conclusions: The recurrence rate of patients with stage Ⅲ-Ⅳ endometriosis after laparoscopic conservative surgery is relatively high, dysmenorrhea and r-AFS score are risk factors for postoperative recurrence, which should be quantified and included in the model to predict the risk of recurrence. Postoperative GnRHa treatment for 6 months and postoperative pregnancy can reduce the recurrence rate. Patients with fertility desire are encouraged to actively prepare for pregnancy after GnRHa treatment.
