Abstract
Despite recent work, diversion colitis remains poorly defined. Thirty-four patients, scheduled for colostomy closure, were prospectively evaluated with flexible sigmoidoscopy for diversion colitis. Biopsies and cultures were obtained if colitis was identified at endoscopy. All biopsy materials and cultures were consistent with inflammation only. The vast majority of patients were in good general health, and their colostomies were constructed as the result of trauma. Eight patients (24 percent) had normal-appearing colons at an average of 16.6 weeks following diversion. Twenty-six patients (76 percent) demonstrated mild to severe colitis at an average of 29.9 weeks following diversion. Three complications occurred in 22 patients after colostomy closure: two wound infections in patients with colitis and one in a patient with a normal colon. We conclude that diversion colitis in an otherwise individual constitutes no increased risk of infection following colostomy closure.
