Abstract
One-hundred and thirty-nine resections were performed for diverticular disease at St. Mark's Hospital, London, during the period from 1964 to 1969. One hundred and three of the resections were done on selected cases before any of the clinically recognized complications of the disease had occurred. In 46 of the resected specimens no evidence of inflammation could be found despite meticulous examination by the pathologist. The surgical procedures were accompanied by no mortality, moderate morbidity, and a gratifying relief of symptoms, which are contrary to the generally held belief that surgery for diverticular disease is hazardous.
