Laparoscopic Assisted Radical Resection Of Rectal Cancer Reserves Left Colic Artery Retrospective Study Of Clinical Significance

Objective:Explore the feasibility and clinical significance of left colic artery in laparoscopic assisted colorectal cancer radical operation.Methods:Retrospective analysis the clinical data of 103 patients in January 2016 to December 2018 in our hospital during the period of receiving laparoscopic resection of rectal cancer,according to the operation of the inferior mesenteric artery(IMA)ligation position of different(keep LCA and keep no LCA),the object of study is divided into two groups:don’t keep the left colic artery(high truncate group of HT,41 cases)and keep the left colic artery(low truncate group ofLT,62 cases),intraoperative and postoperative patients with two groups of related indicators and radical tumor resection degree comparison and evaluation.Result:High ligation group and low ligation operation time,respectively(155.29±21.26)min and(152.10±21.78)min,comparing the two groups,there was no statistically significant difference(P=0.444).Compared two groups of patients in hospital time,high ligation group was(16.90±3.18)days,low ligation group was(17.16±2.88)days(P=0.628),the difference is not significant.The lymph node lymph node cleaning and 253groups of the total number of high ligation group(24.27±9.30),(6.39±2.15),low ligation group respectively(23.89±7.84),(5.92±2.50).(P=0.962,0.249)no statistically significant difference.Start exhaust time,postoperative high ligation group is(38.68±6.65)hours,low ligation group is(33.56±6.46)hours(P=0.000).Statistically significant.High ligation anastomotic fistula in 2 cases in group a,0 cases of low ligation group(P=0.079,X~2=3.084).High ligation group 1 case of postoperative symptoms of abnormal defecate,low ligation group 2 patients(P=0.816,X~2=0.054).High ligation group of postoperative micturition obstacle(3 cases),low ligation group in 2 cases,(P=0.344,X~2=0.894),the difference had no statistical significance.High ligation group the long-term complications of postoperative ischemia diseases occurred in 7 cases,low ligation group 1(P=0.002,X2=9.770),the difference has statistical significance.Conclusion:Laparoscopic radical resection of rectal cancer in left colon artery does not significantly affect the operation time,length of hospital stay,postoperative anastomotic fistula and lymph node cleaning,the incidence of mainland obstacles,can reach the effect with the traditional high ligation of the same operation,also can improve the long-term prognosis,safe and feasible,is worth to recommend.
