Gastrointestinal Pathology: Large Intestine: Idiopathic Megacolon

01 July 2011
Presented by Simon Cross.




George B., aged 48 years, was admitted under Sir Arbuthnot Lane for constipation and abdominal distension dating from infancy, and which entirely prevented him from leadiing an active life. For ten years he had had no action of the bowel except with enemata. Sigmoidoscopy showed a dilatation, commencing above a sharp angulation at the pelvic-rectal junction. Complete colectomy was performed, but general peritonitis set in, and he died eight days later. Examination of the resected colon shows a uniform dilatation reaching 23 inches in circumference filled with semi-fluid faeces weighing 56 lbs.
