Abstract

Gastric antral web (GAW) is a rare anomaly of the gastric antrum and can result in gastric outlet obstruction. Currently, endoscopic treatment of GAW is considered challenging due to high technical requirements and restenosis. Herein, we present a rare case of a paediatric patient with GAW cured by endoscopic transection and partial resection of the web. An 8-year-old boy was admitted because of a 9-month history of postprandial fullness and intermittent non-bilious vomiting of gastric contents. On performing upper gastrointestinal contrast and gastroscopy, the diagnosis of GAW was confirmed. Then, three electroincisions were performed in a radial fashion. Moreover, about a third of the web located in the larger curvature was resected. On follow-up for 6 months, the patient was completely relieved of the postprandial fullness and non-bilious vomiting. Hence, endoscopic treatment for GAW was considered safe and effective for this case. Furthermore, partial resection of the web contributed in avoiding restenosis.
