Collagen synthetic capacity throughout the uninjured and anastomosed intestinal wall.
The capacity to synthesize collagen was measured throughout the intestinal tract of the rat, using an in vitro technique. In addition, the effect of anastomotic construction in either the ileum or the colon on collagen synthetic capacity at specific distant locations both 1 and 4 days after operation was investigated. Collagen synthetic capacity is relatively uniform throughout the large bowel. However, in the small bowel in which synthesis is lower than in the large bowel, synthesis is significantly higher in the most proximal and distal segments than in the intermediate tissue. Anastomotic construction in either part of the bowel strongly increases collagen synthetic capacity at the immediate wound site. The synthetic response is not restricted to the anastomotic site but appears to be more generalized and is, in the small bowel, to some extent specific for collagen since the collagen synthetic capacity is increased far more than the capacity to produce noncollagenous protein. Anastomotic construction in the colon has only minor, although sometimes significant, effects on collagen synthetic capacity in the ileum, and vice versa.
