Comparison of different types of single-port laparoscopic surgery in posterior uterine fibroid resection

This study aims to objectively assess the effect of three surgical approaches for posterior uterine fibroid resection: transumbilical laparoendoscopic single-site surgery (LESS), vaginal natural orifice transluminal endoscopic surgery (vNOTES) in prone position (vNOTES-P), and vNOTES in the lithotomy position (vNOTES-L). A retrospective analysis was conducted on data pertaining to all patients who underwent vNOTES and LESS for single posterior fibroids at our institution from January 2023 to July 2023. Patients were categorized into three groups based on the surgical approach: vNOTES-P group (n = 30), vNOTES-L group (n = 17), and LESS group (n = 32). Comparative analysis was performed on the demographic characteristics and perioperative outcomes among the three groups of patients. All 79 patients underwent surgery without the need for conversion to laparotomy. There were no statistically significant differences among the LESS group, vNOTES-P group, and vNOTES-L group in terms of operative time, intraoperative blood loss, and perioperative complication rates. In the vNOTES-L group, two patients required conversion to LESS during surgery. Patients had faster return of bowel function (less time to flatus) in the vNOTES group compared to the LESS group (P < 0.05). However, three cases of postoperative infection occurred in the vNOTES group, while none were reported in the LESS group. Compared to LESS, vNOTES demonstrates significant advantages in alleviating postoperative pain, shortening time to passage of flatus, speeding recovery and enhancing cosmetic outcomes. Particularly, vNOTES-P for posterior uterine fibroid resection, as an emerging surgical approach, offers certain advantages in facilitating surgical maneuverability and reducing operative time, rendering it more suitable for posterior uterine fibroid resection.
