Abstract
A gastric diverticulum is an outpouching from the stomach wall. It is usually seen in the posterior gastric wall and the gastric antrum. Diverticula arising from the pyloric region are extremely rare. A 59-year-old female presented with progressively worsening symptoms of gastric outlet obstruction associated with dyspepsia and vague abdominal pain for 5 years. A large, thin-walled, wide-mouthed, false gastric diverticulum (filled with undigested food) arising from the pylorus associated with gastric outlet stenosis was found by endoscopy and CT imaging. Multiple biopsies from the region excluded a gastric malignancy. A gastrojejunostomy and jejunojejunostomy were performed to bypass the obstruction which successfully relieved the symptoms. This is an unusual site for gastric diverticula, and when associated with gastric outlet obstruction, further distention of the diverticulum may cause more obstruction with worsening symptoms.
Highlights
A gastric diverticulum is an outpouching from the stomach wall and has similar characteristic diverticula from other parts of the gastrointestinal tract such as the small and large intestines [1]
Most patients are asymptomatic, occasionally patients present with abdominal symptoms. These include dyspepsia, vague pain, epigastric fullness, gastrooesophageal reflux disease, and even bleeding or perforation [1, 2]. These are usually seen in the posterior stomach wall and the gastric antrum, and diverticula arising from the pyloric region are extremely rare [1]
We present a case of a large false gastric diverticulum arising from the pylorus associated with gastric outlet obstruction with a brief review of literature
Summary
A gastric diverticulum is an outpouching from the stomach wall and has similar characteristic diverticula from other parts of the gastrointestinal tract such as the small and large intestines [1] These are very rare with a prevalence of 0.04% in contrast imaging and 0.01%-0.11% in upper gastrointestinal endoscopies [1]. Most patients are asymptomatic, occasionally patients present with abdominal symptoms These include dyspepsia, vague pain, epigastric fullness, gastrooesophageal reflux disease, and even bleeding or perforation [1, 2]. These are usually seen in the posterior stomach wall and the gastric antrum, and diverticula arising from the pyloric region are extremely rare [1]. We present a case of a large false gastric diverticulum arising from the pylorus associated with gastric outlet obstruction with a brief review of literature
