Abstract: Objective To explore the effectiveness and safety of laparoscopic presacral neurectomy (LPN) in treating endometriosis-associated pain. Methods Totally 64 patients with endometriosis were divided into two groups using prospective non-random method. Patients in the control group received only the conventional laparoscopic resection of endometriosis lesions, while patients in the LPN group underwent LPN in addition to the resection of endometriosis lesions. The pre-operative pain scores, intra-operative staging Results, surgical duration, intra-surgical blood loss, post-operative pain relief were compared between these two groups. Results These two groups showed no significant differences in terms of age, body weight, pre-operative pain score, surgery staging, surgical duration, and intra-operative blood loss (all P>0.05). All patients were followed up for 6 to 18 months (median: 12.8 months). The post-operative pain relief rate was 89.28% (25/28) in LPN group and 61.29% (19/31) in the control group (P=0.030). ConclusionLPN can effectively and safely in treating endometriosis and its associated pain.
