[Colonic complications of acute necrotizing pancreatitis].

Among 126 patients operated upon for acute necrotizing pancreatitis in our department over a 10-year period starting in November 1979, 17 had a colonic resection. Colectomy was made mandatory by a necrotic or ischaemic appearance (12 cases, including 3 bowel perforations), an isolated perforation (2 cases) or extensive fat necrosis of the pericolonic atmosphere (3 cases). The hospital mortality was 5 out of the 17 cases. In 6 patients, the pathological results suggested that colonic resection was unnecessary. Since May 1988, a diverting loop ileostomy has been performed whenever colonic viability was found to be dubious at laparotomy. After this policy was introduced no case of secondary colonic complication was encountered. Nevertheless, there still are "abusive" colectomies unjustified by the pathology. Their number should be reduced by a more cautious indication of colonic resection in acute necrotizing pancreatitis.
