Prepyloric Diverticulum in a Nigerian: Case Report of a Rare Finding

Diverticulae are uncommonly encountered in the stomach. They can be congenital or acquired- the latter variety being the less frequent of the two. This article details one such rare case from Lagos, Nigeria and discusses certain aspects of its clinical and endoscopic presentation. We present a 59-year old with a background history of non-steroidal anti-inflammatory drugs abuse presented with hematemesis and melena and was in hemorrhagic shock. After stabilization, the gastroscopy findings were of a gastric diverticulum (GD) in the anterior prepyloric wall. There was a Forrest IIb ulcer in the GD’s wall with surrounding erythema and edema. The patient was successfully managed medically and conservatively and with good long term results.
