Abstract
A 66-year-old man with upper abdominal pain was admitted to the hospital. Abdominal CT and arterial blood gas data suggested the possibility of strangulated ileus and intestinal necrosis. During surgery, a diverticulum tied a loop of ileum and caused intestinal necrosis. Histopathological examination showed a diverticulum with all layers of the ileum. No ectopic mucosa was seen. Strangulation by a knot is the least known method of complicating Meckel's diverticulum. Such a type of diverticulum is characteristic in that it has a long neck and an ampulla at its distal end.
