Acute mesenteric infarction.

Twenty-three cases of mesenteric infarction were reviewed retrospectively. Of note are high surgical mortality and frequent misdiagnosis. Patients are generally older than 60, and have severe, poorly localized pain and nonspecific physical findings. Laboratory studies of value include evidence of hemoconcentration and leukocytosis. Roentgenographic findings are equally nonspecific unless late in the course. Recommended operative procedures depend on the etiology of the infarction. Hyperalimentation may be of benefit early in the postoperative course to provide both nutrition and a chance for adaptation.
