Cytostatics and anastomotic healing in the intestine: an experimental study on the effect of parenteral nutrition.

The effects of parenteral nutrition on the healing of experimental ileal and colonic anastomoses constructed on the 3rd day of a 5-day cytostatics course were investigated. Intravenous saline alone already reduced weight loss induced by cytostatics while parenteral nutrition almost completely prevented postoperative loss of weight. A negative effect of cytostatics on anastomotic bursting strength was found in the ileum 7 days after operation. Parenteral feeding negated this effect but had no positive effect on anastomotic hydroxyproline content. Thus, parenteral nutrition increases the strength of intestinal anastomoses, constructed during a cytostatics regimen, but intravenous saline alone also appears to have a similar effect.
