GIANT GASTRIC DIVERTICULUM ON GREATER CURVATURE OF THE CORPUS: REPORT OF A CASE

Abstract

Diverticula of the stomach are comparatively rare among diverticula of digestive tract. In reviewing several reports, incidence of gsatric diveticula ranged from 0.01% to 0.20%. Most of gastric diveticula occur at the cardia and the lesser curvature toward the posterior wall and diverticula on the greater curvature of the corpus are very rare (2.3% of whole gastric diverticula in Palmer's review). About the size of diverticula, the majority of them measure from 2.1 cm to 3.0 cm and over 5.1 cm are rare (6.9% in Hirota's review). On the wall structure, most of diverticula occuring in the cardia are true. A 48-years-old female was admitted because of heart burn, epigastralgia and loss of appetite. An upper gastrointestinal radiograph showed giant gastric diverticulum in the corpus arising from the greater curvature. Endoscopic examination revealed giant gastric diverticulum at the same position as above. Celiotomy was carried out because symptoms continued resisting to concervative treatment. The diverticulum measured 11.5cm×8.0 cm and it was a pseudodiverticulum.
