Small bowel diverticulosis is a rare disease that is usually associated with recurrent pseudo-obstruction, bacterial overgrowth, and malabsorption. The more severe complications include hemorrhage and perforation. There is evidence to suggest that this entity is a result of small bowel motor dysfunction. For this reason, it has been associated with disorders in which a myopathic or neuropathic process is involved, such as scleroderma. The majority of patients with jejunal diverticulosis do not require surgery and can be managed medically. We report a case of jejunal diverticulosis in a 63-year-old gentleman who presented with symptoms of pseudo-obstruction. Ambulatory duodenojejunal manometry revealed several abnormalities suggestive of small bowel motor dysfunction. Enteroclysis, however, did not find evidence of mechanical obstruction, and the patient had marked improvement with cisapride and antibiotics.
