A comparative study on the application of biofragmentable anastomosis ring and manual-suture in intestinal anastomosis

Objective To compare the application of biofragmentable anastomosis ring and conventional manual suture in intestinal anastomosis. Methods 180 patients undergoing intestinal resection with primary anastomosis were divided into a manual suture group (control group)and biofragmenfable anastomosis ring group (BAR group). The anastomoses of 92 cases enrolled in the BAR group was performed with BAR, whereas the other 88 cases in manual suture group were done by standard double layer suture. The restoration time of bowel functions, post-operative complications of anastomotic leaks, bleeding and obstruction were recorded in each group. Results A dead case was recorded in BAR group, but was not related to anastomotic problems. Anastomotic leaks occurred in 1 case in BAR group and 2 cases in manual group. 7 cases incomplete obstruction occured in BAR group and 2 cases in manual suture group respectively(P 0.05=. Post-operative bowel restoration time was 27.2±5.6 h and 49.6±8.7 h respectively,the difference was statistically significant(P 0.01=. The anastomtic inflammatory reaction occured 1 case(2.22%)in BAR group and 11 cases in manual group, the difference was statistically significant(P 0.01=. Conclusion BAR is a safe and effective device in intestinal anastomosis, especially in emergency patients with high-risks. It may be applied as a standard anastomotic method.
