Jaundice and wound healing: an experimental study.

Obstructive jaundice was induced in rats by ligation and division of the common bile duct. The healing of a standard gastric incision and a parietal peritoneal defect in these animals showed histological evidence of delayed healing compared with controls. The bursting strength of the abdominal incision was also lowered, but not that of the stomach, probably because of the adhesions which reinforced the gastric incisions. Angiography did, however, reveal delay in angiogenesis in the gastric wounds of jaundiced animals. The possible causes of this delay in healing and its clinical implications require further investigations.
