ABSTRACT
OBJECTIVE@#To explore the feasibility, safety and the economical efficiency of double-pouch anastomosis in laparoscopic radical rectal cancer assisted by small incisions.@*METHODS@#Clinical data of 224 patients undergoing gastrointestinal surgery at Taizhou People's Hospital of Jiangsu Province from January 2011 to December 2017 were retrospectively analyzed. Indusion criteria: patients were diagnosed as primary rectal adenocarcinoma by preoperative enteroscopy pathology, the distance of the tumor to anal margin was from 4 to 15 cm, and patients were treated with laparoscopic total mesorectal excision(TME) through small incision. Patients were divided into two groups according to different anastomosis method, double-pouch group(108 cases) and single-pouch group (116 cases). The surgical indexes, tumor safety indexes, short-term efficacy and economic indexes were compared between the two groups.@*RESULTS@#There was no significant difference between two groups in baseline data, operative time, blood loss, number of lymph nodes dissection, average length of proximal and distal bowel, or incidence of urination and sexual dysfunction (all P>0.05). Compared with the single-pouch group, the double-pouch group presented lower anastomotic secondary bleeding rate [0.9%(1/108) vs. 6.0% (7/116), χ²=4.238, P=0.040], lower incidence of anastomotic leakage[1.9%(2/108) vs. 7.8%(9/116), χ²=4.179, P=0.041], lower incidence of anastomotic stricture [1.9% (2/108) vs. 8.6% (10/116), χ²=5.054, P=0.025], shorter hospital stay [(13.4±3.9) days vs. (15.9±9.8) days, t=2.524, P=0.013] and less average hospitalization costs [(34 000±7 000) yuan vs. (46 000±23 000) yuan, t=5.047,P0.05).@*CONCLUSION@#Laparoscopic TME assisted by small incision with double-pouch anastomosis is a safe, feasible and economical method.
