腹腔镜下直肠癌根治术中保留左结肠动脉治疗直肠癌的效果观察OA

Objective:To explore the effect of preserving the left colon artery(LCA)during laparoscopic radical resection of rectal cancer on surgical related indicators and gastrointestinal function recovery in rectal cancer patients.Method:A total of 150 rectal cancer patients from the First Hospital of Putian City from January 2020 to January 2023 were selected,they were divided into a group with preserved LCA(75 cases)and a group without preserved LCA(75 cases)based on whether or not to retain LCA.The surgical related indicators and gastrointestinal function recovery between two groups were compared.Result:There were no statistically significant differences between the two groups in terms of intraoperative bleeding volume,surgical time,number of lymph node dissection at the root of the inferior mesenteric artery(IMA),total number of lymph node dissection and length of hospital stay(P>0.05).The levels of motilin and gastrin in the group with preserved LCA at 3 days after surgery,and the gastrointestinal quality of life index(GIQLI)score at 3 months after surgery were higher than those of the group without preserved LCA,the differences were statistically significant(P<0.05).There were no statistically significant differences in the levels of CD3+,CD4+and CD8+between the group with preserved LCA and the group without preserved LCA before and 3 days after surgery(P>0.05).The incidence of complications in the group with preserved LCA was lower than that in the group without preserved LCA,the difference was statistically significant(P<0.05).Conclusion:Preservation of LCA during laparoscopic radical resection of rectal cancer has no significant impact on surgical related indicators and immune function in rectal cancer patients,but can promote gastrointestinal function recovery and reduce postoperative complications.
