Brown bowel syndrome, an unusual cause of sigmoid volvulus

Abstract

We report a case of a 79-year-old gentleman who presented to the emergency department with a 5-day history of abdominal pain, constipation, a progressively distending abdomen and new onset feculent vomiting on a background of a recent endoscopic decompression of a sigmoid volvulus. Investigations confirmed the presence of a recurrent sigmoid volvulus. Attempts to reduce this endoscopically failed and laparotomy with sub-total colectomy and ileostomy formation was performed. Histology from the resected specimen identified a distinct pathology, namely intestinal lipofuscinosis also known as brown bowel syndrome. Brown bowel syndrome is a recognized but rare complication of chronic long term malnutrition. It may present in a myriad of ways including atonia and, rarely, massive colonic dilatation, as in our case.
