A biofragmentable ring for sutureless bowel anastomosis

Abstract

A biofragmentable bowel anastomosis ring (BAR) for sutureless intestinal anastomosis is described with the laboratory results comparing the BAR to sutured and stapled anastomoses. There was equivalent healing with all three methods of anastomosis. However, "burst" pressure was highest at day zero and overall necrosis was least with the BAR. By virtue of these findings and being sutureless, it is hoped that the limits of safe bowel anastomosis can be extended.
