Abstract: Objective To compare the anastomosis effects of biodegradable anastomosis ring(BAR) and anastomat in right hemicolectomy. Methods Eighty-seven patients who underwent right hemicolectomy in our hospital were retrospectively analyzed.Of these patients,49 underwent anastomosis using anastomat,38 underwent anastomosis using BAR.The incidence of anastomosis fistula and stenosis,abdominal infection,postoperative ileus,gastrointestinal hemorrhage,incision infection,recovery time of intestinal function,and material cost were compared between the two intestinal anastomosis procedures. Results No anastomosis fistula and stenosis,abdominal infection,postoperative ileus occurred in all the patients.Lower gastrointestinal hemorrhage and incision infection were observed in 1 and 3 patients respectively after anastomosis with anastomat,and incision infection occurred in 2 patients after anastomosis with BAR with no significant difference.The recovery time of intestinal function was 3.1 days and 3.5 days respectively after anastomosis with BAR and anastomat with no significant difference.However,the recovery time of intestinal function was shorter after anastomosis with BAR than after anastomosis with anastomat.The average cost for the anastomosis with BAR and anastomat was about 3 427 and 5 231 RMB Yuan,respectively. Conclusion BAR is as safe as anastomat when they are used for anastomosis in right hemicolectomy.However,it is more beneficial to the recovery of intestinal function and more economical than anastomat.
