[Effect of anastomosis technic on wound healing in the gastrointestinal tract. Animal experiment study of the dog colon with special reference to manual suture technics].
Three manual suture techniques (double-layer inverting, single-layer end-to-end, and continuous suture of the submucosa) were compared with anastomoses performed by stapling instruments (EEA, KZ 28) on the canine colon. The two manual techniques with exact end-to-end apposition led to primary wound-healing during the early postoperative period (3-20 days). There was no significant stenosis at the site of anastomosis five and ten months postoperatively. Inverting sutures as well as stapled anastomoses, however, showed delayed healing with considerable inflammatory reaction, resulting in marked stenosis after five to ten months.
