Large bowel obstruction in pregnancy: a rare entity, an unusual cause

Abstract

Large bowel obstruction is a rare and difficult diagnosis in pregnancy. Common causes are caecal and sigmoid volvulus and less common pseudo-obstruction. An infrequent cause of large bowel obstruction from an adhesive band in pregnancy causing diagnostic difficulty is reported. Report of an unusual cause of large bowel obstruction in pregnancy. Diagnostic colonoscopy confirmed large bowel obstruction at the level of sigmoid. Laparotomy revealed this to be from a single band adhesion originating from the site of previous appendicectomy. Division of the band resolved the obstruction. A high index of suspicion is necessary for the diagnosis of large bowel obstruction in pregnancy especially in women with previous history of abdominal or pelvic surgery. Colonoscopy is helpful avoiding radiation to foetus and mother. Prompt surgical intervention reduces risks and maximises chances for a favourable outcome for both mother and child.
