[Anastomoses of the small intestine in a septic environment protected by polyglactin 910-collagen mesh. Experimental study in rats].
An experimental study was carried out in rats to evaluate the outcome of small bowel anastomoses in the presence of peritonitis with and without protection by a polyglactin 910 mesh. One hundred and thirty rats were operated. 1) Thirty small bowel anastomoses were performed in a sterile environment to evaluate the morbidity and mortality due to the surgical procedure itself. All these animals had an uneventful course. 2) Forty anastomoses were performed in a septic environment without protection. Twelve rats died immediately after the procedure. Six rats developed an anastomotic fistula and 22 had an uneventful course. 3) Sixty anastomoses were performed in a septic environment and protected by a polyglactin 910 mesh. Seventeen rats died immediately after the procedure. There were no anastomotic disruptions. Seventeen rats had an uneventful course, and 28 (65%) developed stenosis of the anastomosis. Protection of small bowel anastomoses by a polyglactin 910 mesh appears to effectively prevent disruptions (no anastomotic fistulae or locoregional infections were recorded). However, the mesh is responsible for an intense inflammatory reaction, that often results in intestinal obstruction.
