RESUMO
In occidental countries, more than 50% of people aged more than 80 years have a pelvic colon [sigmoid] diverticulosis. In absence of any epidemiological study, in Morocco, this affection seems to be rare. We report here 4 cases admitted in a non urgent surgical department during 10 years, two men and two women, aged between 40-58 years old. All of them were managed for a complicated stage of sigmoid diverticulosis. These complications were presented by sigmoid stenosis, perisigmoid abcess, purulent peritonitis and acute sigmoiditis. The first three patients were operated. The first one had a non urgent recto-sigmoidal hinge resection. The other two had an urgent intervention, but the diverticular origin was not evoked except after the surgical intervention, one only of them had another intervention for resection of the recto-sigmoidal hinge. The second patient refused to be reoperated. The last patient was medically treated. For a better therapeutic management of diverticular diseases we must know the evolutional aspects of this disease
