Comparison of the influence on the healing of anastomotic stoma between two kinds of alimentary canal reconstruction after laparoscopic radical resection of low rectal cancer

Abstract

Objective To investigate the different influencing on the healing of anastomotic stoma between two kinds of alimentary canal reconstruction after laparoscopic radical resection of low rectal cance. Methods The clinical data of July 2013-January 2016 suffering from stage Ⅱ-Ⅲ low rectal cancer and in our hospital underwent laparoscopic colorectal cancer radical surgery patients was retrospectively analyzed.Through accessing to medical records, the patients of diabetes, hypoproteinemia, malnutrition, preoperative uncorrectable cases and received neoadjuvant therapy were excluded.More than a total of 59 cases were enrolled, 34 cases of them received traditional alimentary canal reconstruction(traditional group, including 26 cases of low rectal cancer, 8 cases of super low rectal cancer, also 21 cases of them in stage Ⅱ and 13 cases in stage Ⅲ), 25 cases of them received anal anastomosis resection (including 18 cases of low rectal cancer, 7 cases of super low rectal cancer, also 20 cases of them in stage Ⅱ and 5 cases in stage Ⅲ). Results In the traditional group, 1case of 34 patients with anastomotic leakage, 3 cases of anastomotic bleeding, while in the improved group, 2cases of 25 patients with anastomotic leakage, 2 cases of anastomotic bleeding.There was no significant difference in the incidence of anastomotic leakage and anastomotic bleeding between the two groups(3cases vs.2cases, 1case vs.2cases, χ2=0.13, 0.75, all P>0.05). All cases did not occur in patients with anastomotic stenosis, and all patients were cured and discharged. Conclusion Each of the two methods have their advantages and disadvantages.Through preoperative, intraoperative evaluation of tumor status, reasonable choice of tumor treatment and anastomosis, is more conducive to postoperative recovery.
