Intramural duodenal haematoma with mucosal prolapse causing intestinal obstruction.

Intramural small bowel haematoma is a rare cause of intestinal obstruction in children. Coagulation disorders or anticoagulant therapy are the most common cause followed by blunt trauma. A one and half-year-old boy, with known case of gastro-oesophageal reflux disease had undergone upper gastrointestinal endoscopy and biopsy. Four days later, he presented to us with clinical features of small bowel obstruction. CT of the abdomen showed features suggestive of haemorrhagic duplication cyst. Explorative laparotomy revealed 15-20 cm of bowel from the third part of the duodenum to proximal jejunum filled with clotted blood and thinned out serosa. There was no evidence of intraluminal blood in the distal bowel loops. Resection of the involved bowel with primary anastomoses was done. Histopathological examination of bowel revealed intramural haematoma associated with prolapse of the mucosa. There was no evidence of duplication cyst or vascular malformations. Postoperative period was uneventful. © BMJ Publishing Group Limited 2019. No commercial re-use. See rights and permissions. Published by BMJ.
