A rare case of extrathoracic large bowel obstruction following colonic interposition.

Transverse colon interposition for oesophageal replacement following oesophagectomy is a rarely seen entity; interposition of the colon exterior to the thoracic cage is rarer still. Here, we report the case of a patient presenting with a large bowel obstruction in a transverse colon interposition located subcutaneously anterior to the sternum, with the diaphragm fully intact, following chest compressions for multiple cardiac arrests. The need for specialty input was highlighted early on, and the large bowel decompressed via nasogastric tube insertion into the interpositioned colon. The patient was then transferred to the acute coronary unit for further observation and management.
