title: Anastomotic healing after resection of left-colon stenosis: effect on collagen metabolism and anastomotic strength. An experimental study in the rat.
abstract: Anastomotic breaking strength and collagen metabolism in the colonic wall were studied after resection of a standardized left-colon stenosis in the rat. An increased complication rate was found in the stenosis group compared with the control group (27 percent vs. 2 percent) and the complications arise soon after surgery. The collagen turnover in the anastomotic area, as well as the changes of breaking strength, were equal between the groups in the early healing course, implying that the stenosis group, as an entity, did not show impairment in the studied parameters predisposing for complications. Other factors such as mechanical strain by the increased fecal bulk and increased bacterial load may contribute to occurrence of the anastomotic complications.
