Abstract: Objective   To explore the impacts of different abdominal auxiliary incisions on postoperative gastrointestinal function and quality of life in patients with laparoscopic radical rectal cancer surgery.  Methods   The clinical data of  180 cases of patients who underwent laparoscopic radical rectal cancer surgery in our hospital from January 2015 to October 2021 were retrospectively analyzed.According to different abdominal auxiliary incisions,60 patients with subumbilical median incision(group A) were randomly selected,and 60 patients with supraumbilical longitudinal incision were selected.Patients(group B),60 patients with oblique incision in the left lower abdomen(group C).The operation-related indicators,postoperative gastrointestinal function,postoperative pain score,postoperative 3-day quality of life,and complications were compared among the three groups.  Results   The auxiliary incision length in group A was greater than that in groups B and C(P<0.05).Compared with group C,group A and group B had advantages in the time of first getting out of bed,the time of first flatus,the recovery time of bowel sounds,the VAS score of pain,and the levels of gastrin,motilin,and quality of life QLQ-CR38 scale score 3 days after operation, the difference was statistically significant (P<0.05).The incidence of incisional hernia in groups A and B was significantly lower than that in group C, and the difference was statistically significant (P<0.05).  Conclusion   Compared with the left lower abdominal oblique incision,the supraumbilical longitudinal incision and the subumbilical median incision have positive short-term curative effects in patients with laparoscopic radical rectal cancer surgery,and they have the advantages of lower pain,higher quality of life,and faster recovery of intestinal function.
