Background/Aim: The aim of this study is to evaluate the diagnostic and the
rapeutic difficulties of gastric duplication cysts. Methods: A 38-year-old
female patient presented with dyspepsia and repeated episodes of epigastric
pain. She was operated with the diagnosis of pancreatic pseudocyst accordi
ng to her US and CT scans, and found to have a gastric duplication cyst. A
cyst about 80 x 80 mm, localized on the posterior wall of the corpus of the
stomach close to the fundus, was dissected from the surrounding tissues an
d partially from the gastric wall. The cyst did not have muscle layer on th
e common wall with the stomach, so the cystic mucosa was stripped away from
the gastric muscle layer. The gastric lumen was not entered. Results: Alth
ough gastric duplication cysts do not have specific symptoms and signs, CT,
MR and endoscopic ultrasonography may help the preoperative diagnosis, but
the diagnosis is usually confirmed at laparotomy. Needle aspiration may ca
use complications. Conclusion: Because of the complications that may occur
after needle aspiration and malignant potential of the tissue, the treatmen
t of these cysts is surgical. Copyright (C) 2000 S. Karger AG, Basel.
