Abstract:
Objective To explore the clinical efficacy of different ligation methods in laparoscopic radi-cal resection of rectal cancer and sigmoid colon cancer and the influencing factors of anastomotic leakage.Methods A total of 82 patients who underwent laparoscopic radical resection of rectal cancer and sigmoid co-lon cancer in this hospital from December 2022 to December 2023 were selected and divided into the low-liga-tion group(n=42)and the high-ligation group(n=40)according to different surgical methods.The inferior mesenteric artery(IMA)classification,IMA length,operation time,intraoperative blood loss,total number of lymph node dissections,number of lymph node dissections in group 253,postoperative hospital stay,exhaust time,incidence of urinary retention,incidence of anastomotic leakage,and incidence of preventive stoma were compared between the two groups.Univariate and multivariate logistic regression analyses were conducted to analyze the influencing factors of anastomotic leakage in patients undergoing radical resection of rectal cancer and sigmoid colon cancer.Results There was no statistically significant difference in IMA length,IMA classi-fication proportion,operation time,intraoperative blood loss,the total number of lymph node dissections,the number of lymph node dissections in group 253,and the postoperative hospital stay between the two groups(P>0.05).Compared with the high-ligation group,the low-ligation group had a shorter exhaust time,lower incidence of anastomotic leakage and preventive ostomy,the differences were statistically significant(P<0.05).Anastomotic leakage occurred in 7 patients.Univariate analysis showed that whether left colic artery(LCA)was preserved,tumor location,presence of underlying diseases,and preventive stoma were associated with anastomotic leakage in patients undergoing radical resection of rectal cancer and sigmoid colon cancer(P<0.05).Multivariate logistics analysis showed that whether LCA was preserved,tumor location,presence of underlying diseases,and presence of preventive stoma were not influencing factors for anastomotic leakage in patients undergoing radical resection of rectal cancer or sigmoid colon cancer(P>0.05).Conclusion In laparoscopic radical resection of rectal and sigmoid colon cancer,the clinical efficacy of preserving LCA is com-parable to that of not preserving LCA,and it can reduce the risk of anastomotic leakage and the probability of preventive stoma,promoting the early recovery of intestinal function.
