Sleeve anastomosis of the intestine. Physical and biochemical studies of a new intestinal anastomosis in rats.
A new, sleeve-shaped interpositional anastomosis of the small intestine was tested in rats. It was compared with a conventional two-layer anastomosis as regards healing, bursting strength, collagen content and complications. Each type of anastomosis was constructed in a separate group of 38 rats. The complications rate did not differ between the two groups. At 2 and 4 days postoperatively the bursting pressure was significantly higher in the sleeve anastomosis than in the conventional anastomosis. Hydroxyproline content did not differ between the two types of anastomosis. The study demonstrated superior breaking strength of sleeve anastomosis in the early postoperative period compared with conventional two-layer anastomosis. This finding merits further investigation.
