Elimination of Postoperative Pyloric Stricture by Endoscopic Electrocauterization and Balloon Dilatation in an Infant With Congenital Antral Web

Abstract

We, herein, report a male infant who presented with recurrent pyloric stricture after two surgeries (web excision and antropyloroplasty), which were done, respectively, at 5 days of age for congenital antral web and 6 months of age for the subsequent pyloric stricture. The patient suffered from anorexia, progressed vomiting, and weight loss gradually after the first and second surgeries, and then, endoscopy revealed severe pyloric deformity and stricture. Poor inflation was noted during endoscopic balloon dilatation because of tight pylorus; a subsequent electrocauterization and balloon dilatation were done, and the patient’s clinical symptoms improved significantly 2 weeks later. A follow-up endoscopy was performed 1 month and 12 months after endoscopic therapy, showing steady regression of pyloric stricture. The patient had adequate diet intake and growth in the later 12 months.
