Clinical Study On Left Colonic Artery Preservation During Laparoscopic Radical Resection Of Rectal Cancer

Objective:to analyze the necessity and clinical value of left colonic artery reservation in laparoscopic radical resection of rectal cancer.Methods:Collected in January 1,2018 to June 30,2019 in the hospital to see a doctor of the clinical data of 110 cases of patients with rectal cancer were retrospectively analyzed,according to whether the reserves left colic artery should be divided into two groups,observation group and control group,respectively,two groups of patient's age,BMI,tumor length to diameter and distance from anal edge and postoperative pathological conditions there was no statistically significant difference(P>0.05),comparable.The blood loss,operation time,prophylactic ileostomy fistula,anastomotic leakage,splenic area dissociation,postoperative anal exhaust time,number of lymph nodes dissected and positive rate of 253 groups were observed,compared and analyzedResults:In this study,there was no statistically significant difference between the two groups in general conditions and postoperative pathological conditions(P>0.05).Perioperative conditions of the two groups of patients in the control group,6 patients received colonic splenic triolysis,the proportion of which was 12.8%of the total number of patients in the control group,which reduced the anastomotic tension.In the observation group,1 patient underwent colon-splenic dissociation,and the difference between the two groups was statistically significant(P<0.05).6 patients in the control group underwent prophylactic terminal ileostomy,accounting for 12.8%of the total number of patients in the control group.In the observation group,1 patient underwent prophylactic terminal ileostomy,and the difference between the two groups was statistically significant(P<0.05).There were 8 cases of anastomotic leakage in the control group,which was 17%of the total number of patients.There were 2 cases of anastomotic leakage in the observation group,which was 3.2%of the total number of patients,and there was a significant difference between the two groups(P<0.05).There was no statistical significance in terms of blood loss,operation time,postoperative exhaust time,number of lymph node dissection and positive rate of 253 groups(P>0.05).Conclusions:Laparoscopic radical resection of rectal cancer to preserve the left colonic artery will have a certain effect on the outcome of treatment.It does not affect the complete dissection of lymph nodes,does not increase the operation time,and better protects the blood supply of anastomotic stoma,reduces the incidence of free splenic area and ileostomy.Thus it reduces the occurrence of anastomotic leakage,and has certain advantages in radical resection of rectal cancer.
