# Gastric outlet obstruction in an 11‐year‐old girl: A case report

## TL;DR

An 11-year-old girl with gastric outlet obstruction due to pyloric stenosis was successfully treated with surgery.

## Contribution

This case report highlights pyloric stenosis as a rare cause of gastric outlet obstruction in older children.

## Key findings

- The patient had a very small pyloric orifice confirmed by endoscopy.
- Heineke-Mikulicz pyloroplasty resolved the patient's symptoms.
- Abdominal imaging confirmed pylorus thickening.

## Abstract

Pyloric stenosis commonly affects infants and rarely causes gastric outlet obstruction in adolescents and older children. We present the case of an 11‐year‐old girl with a 2‐month history of recurrent postprandial vomiting and weight loss. On physical examination, the patient presented with abdominal distension. Upper gastrointestinal endoscopy revealed a very small pyloric orifice through which the endoscope could not be advanced. Abdominal ultrasonography and a computed tomography confirmed pylorus thickening. She underwent Heineke‐Mikulicz pyloroplasty with symptom resolution.
