[Late postoperative colonic stenosis caused by the biofragmentable anastomosis ring (BAR)]

The authors focused their attention on the prevalence of late postoperative stenoses of anastomoses following resection of the colon. In 42 patients the anastomosis was implemented by means of a Valtrac ring--i.e. by compressive biofragmentable seamless technique. Within an interval of 6 months after surgery the majority of these patients were subjected to colonoscopic examination with direct visualization of the intestinal anastomosis. The authors did not record any late postoperative stenoses of the BAR anastomosis of the colon. Moreover on colonoscopic examination in the majority of patients the original intestinal anastomosis was only difficult to detect.
