title: Influence of methylprednisolone on the healing of intestinal anastomoses in rats.
abstract: Although steroids are generally thought to impair intestinal anastomotic healing, this effect has never been proven unequivocally in either clinical or experimental studies. We have investigated the influence of methylprednisolone (2.5 or 10.0 mg kg-1 day-1) given from 2 days before operation onwards, on 3-day-old and 7-day-old ileal and colonic anastomoses in rats. Anastomotic abscesses occurred more frequently in the ileum, but not in the colon, after steroid medication. However, methylprednisolone did not lower anastomotic bursting pressures in either of the bowel segments. Comparison of the hydroxyproline content of the anastomotic segment yielded no significant difference between control and methylprednisolone groups in either small or large bowel. Thus, healing of experimental colonic anastomoses remains unaffected by short-term administration of this corticosteroid.
