Abstract   

    An expenmental study was conducted on 12 healthy adult dogs to determine the best method for anastomosis of colon. An appositional 2 layer (APP-2) suture pattern was compared with the inverting 2 layer (INV-2) suture pattern for end-to-end anastomosis. Vicry^R (size 3-0) was used for anastomosis. The mean number of stitches and time taken for anastomosis were significantly higher (P<0.05) with APP-2 than INV-2. Adhesions at the incision site were also significantly higher (P<0.05) with APP-2 than INV-2. Lumen diameters for all anastomoses were smaller than control at 10th, 20th and 30th day after surgery with both patterns. The differences between the values of APP-2 and 1NV-2 were not statistically different at 10th and 20th thy after surgery. The lumen diameter with APP-2 was significantly larger (P<0.05) than 1NV-2 at 30th day after surgery. The current study showed the supremacy of the APP-2 layer suture pattern for colonic end- to-end anastomosis over the 1NV-2 layer suture pattern.
