Transumbilical single-port laparoscopy is widely used in gynecological surgery. However, it is rarely used in the treatment of deep infiltrating endometriosis due to its own shortcomings and the complex condition of deep infiltrating endometriosis. The study aims to introduce a transumbilical single-port laparoscopic surgery based on retroperitoneal pelvic spaces anatomy, which can complete the operation of deep infiltrating endometriosis more easily. A retrospective analysis of 63 patients with deep infiltrating endometriosis treated by transumbilical single-port laparoscopy using this method was conducted. The operation duration was 120.00 (85.00 ± 170.00) (35–405) min, the estimated blood loss was 68.41 ± 39.35 ml, the postoperative hospital stay was 5.00 (4.00–6.00) days, and the incidence of postoperative complications was 4.76% (3/63). 1 patient was found to have intestinal injury during operation, 1 patient had ureteral injury after operation, and 1 patient had postoperative pelvic infection, with a recurrence rate of 9.52%. The postoperative scar score was 3.00 (3.00–4.00) and the postoperative satisfaction score was 9.00 (8.00–10.00). In summary, this study demonstrates the feasibility of transumbilical single-port laparoscopic surgery for deep infiltrating endometriosis based on retroperitoneal pelvic spaces anatomy. Hysterectomy, adenomyosis resection, etc. are also feasible with this method, boasting more obvious advantages. This method can make transumbilical single-port laparoscopy more widely used in deep infiltrating endometriosis.

Background: Endometriosis is a common, chronic gynecological disease. Laparoscopy is currently the preferred method of ovarian endometriosis. However, the safety and feasibility of laparoendoscopic single-site surgery for ovarian endometrioid cyst removal still need to be discussed. Objective: To explore the safety and feasibility of laparoendoscopic single-site (LESS) surgery versus conventional multiport laparoscopic (CMPL) surgery for the ovarian endometrioid cystectomy. Methods: We retrospectively analyzed the data of 47 patients who had undergone LESS and LESS ovarian cystectomy due to ovarian endometrioid cyst in our hospital from March 2018 to April 2019. The patients were classified into single-port group (14) and multiport group (33) based on surgical paths. The patients' general characteristics and perioperative outcomes compared. Results: There were no significant statistical differences between the two groups (P>0.05) in the operation time and the maximum body temperature in 24 h after operation. There were significant statistical differences (all P<0.05) in postoperative decrease of Hb, intraoperative bleeding volume, total hospital stay and CS score. Conclusion: LESS for ovarian endometrioid cyst removal is safe and feasible, and it better than CMPL in relieving postoperative pain and inproving cosmetic effects and so on.
