Résumé : Fifteen large-bowel lesions are reported among 12 patients with acute necrotizing pancreatitis: 6 stenoses (transient in one case), 5 necroses and 4 perforations. In 7 cases out of 12, abdominal plain film was suggestive of colonic involvement. Barium enema and coloscopy may confirm the diagnosis. Previously reported cases (56 stenoses, 84 perforations, 35 necroses) are reviewed and clinical course radiographic features and the results of surgical management are discussed.
