title: Intestinal obstruction: still a lethal clinical entity.
abstract: A retrospective analysis of 70 consecutive patients with a clinical diagnosis of intestinal obstruction from January 1983 to September 1985 was reviewed. Mean age was 62 years. Etiological factors included adhesions 50 percent, malignancy 24 percent, volvulus 12 percent, diverticulitis 7 percent, hernias 4 percent, and radiation enteritis, mesenteric infarction, and perforation of the cecum in the remaining 3 percent. Complications included wound infection 9 percent (n = 6), intra-abdominal sepsis 7 percent (n = 5), and recurrent small bowel obstruction 4 percent (n = 3). Overall mortality was 24 percent (n = 7).Results of the univariant analysis showed no association between the clinical signs of intestinal obstruction, that is, fever, tachycardia, leukocytosis, and local tenderness, and gangrenous bowel. A multiple regression analysis showed, however, that only 14 percent of the variance was able to predict the gangrenous bowel based on clinical signs. In conclusion, the classical signs of intestinal obstruction are poor indicators for compromised bowel, and early surgical intervention will reduce the incidence of ischemic bowel and mortality.
