目的:探讨腹腔镜下低位直肠癌根治术的疗效及可行性。方法:回顾分析26例腹腔镜低位直肠癌根治手术的临床资料。结果:23例低位直肠癌患者顺利完成手术,平均手术时间210 min,平均出血180 mL,术后肠道功能平均恢复时间56 h,平均住院9.5 d;手术切除淋巴结平均为15.6个,无术后出血、吻合口瘘、死亡发生;术后随访6~24个月,Trocar及小切口处未见肿瘤种植转移,1例复发。3例中转开腹,其中1例术后随访24个月未见肿瘤转移,2例分别于术后10,13个月死于肿瘤广泛转移导致的全身衰竭。结论:腹腔镜下低位直肠癌根治术患者创伤轻、出血少、胃肠功能恢复快、术后疼痛轻、美学效果好等优点,且能达到根治的要求。 Objective: To investigate the efficacy and feasibility of laparoscopic radical resection of rectal cancer. Methods: The clinical data of 26 cases undergoing laparoscopic radical rectal cancer radical surgery were retrospectively analyzed. Results: Twenty-three patients with low rectal cancer successfully completed the operation, with an average operation time of 210 min and an average bleeding volume of 180 mL. The mean recovery time of intestinal function after operation was 56 h and the average hospital stay was 9.5 days. The average number of resected lymph nodes was 15.6, Bleeding, anastomotic fistula and death occurred. Trocar and small incision had no tumor metastasis and recurrence in 6 to 24 months after operation. 3 cases were converted to open surgery, of which 1 case was followed up for 24 months without tumor metastasis, and 2 cases died of systemic metastasis caused by extensive tumor metastasis at 10 and 13 months after operation. Conclusions: Laparoscopic surgery for patients with low rectal cancer has the advantages of less trauma, less bleeding, faster recovery of gastrointestinal function, less postoperative pain, better aesthetic effect, and can meet the requirements of radical treatment.
