腹腔镜自然腔道标本提取手术与腹腔镜辅助手术直肠癌根治术的近期疗效比较

Objective To explore the feasibility, safety and clinical application value of laparoscopic radical rectal cancer surgery with natural orifice specimen extraction (NOSE) by comparing the postoperative pathological data, surgery-related variables and postoperative recovery between laparoscopic radical rectal cancer surgery with NOSE and laparoscopic-assisted radical rectal cancer surgery. Methods A retrospective analysis was conducted on 74 patients who underwent radical rectal cancer surgery with anus preservation in the Department of General Surgery of The First Affiliated Hospital of Xi'an Jiaotong University from July 2017 to April 2022. Among them, 38 cases underwent surgery with specimen extraction through an abdominal auxiliary incision (auxiliary incision group), and 36 cases underwent surgery with specimen extraction through a natural orifice (NOSES group). The differences in the efficacy of the two surgeries were evaluated by comparing the postoperative pathological data, surgical variables, and postoperative recovery of the two groups. Results There were no statistically significant differences in general data and postoperative pathological data between the two groups (all P>0.05). The NOSES group exhibited significantly shorter operative time, time to first flatus, time to first oral intake postoperatively, and postoperative hospital stay compared to the auxiliary incision group (all P<0.05). However, there were no statistically significant differences in intraoperative blood loss, postoperative complications, and whether secondary surgeries were performed (all P>0.05). Conclusion Laparoscopic surgery with NOSE for rectal cancer is safe and feasible with minimally invasive and accelerated recovery,which is worth promoting and applying in clinical practice.
