ABSTRACT
Objective:To compare and analyze the efficacy of supraumbilical longitudinal auxiliary incision and left lower abdominal oblique auxiliary incision during laparoscopic radical resection of rectal cancer.Methods:The data of 196 patients with rectal cancer treated in the Second Affiliated Hospital of Xiamen medical college from January 2015 to December 2020 were analyzed retrospectively. Different abdominal auxiliary incisions were used for grouping. The control group (101 cases) used the oblique auxiliary incision of the left lower abdomen, and the observation group (95 cases) used the longitudinal auxiliary incision of the upper umbilical cord. The intraoperative indicators (operative time, intraoperative blood loss, auxiliary incision length, distance between anastomotic teeth and dentate line), postoperative indicators (first postoperative exhaust time, postoperative pain score, fluid intake time, first out of bed time and hospital stay) and operative complications between the two groups were compared.Results:The first postoperative exhaust time ((56.8±4.3) h vs. (70.3±5.8) h, t=4.796) and the first postoperative out of bed time ((38.81±2.04) h vs. (47.93±2.63) h, t=5.113) in the observation group were significantly shorter than those in the control group, and the pain scores at 24 hours ((2.01±0.22) vs.(2.43±0.40), t=5.882) and 48 hours pain score ((2.23±0.44) vs. (3.14±0.72), t=6.58) after operation were significantly lower than those in the control group (all P<0.05). The incidence of incision hernia in the observation group was significantly lower than that in the control group (5.3% (5/95) vs.9.9% (10/101), χ 2=4.29)( P<0.05). Conclusion:Compared with the left lower abdominal oblique auxiliary incision,the supraumbilical longitudinal auxiliary incision in laparoscopic radical resection of rectal cancer can not only significantly reduce the postoperative pain scores and recover the postoperative intestinal function as soon as possible, but also significantly reduce the incidence of postoperative incision hernia.
