Abstract
A 48-year-old woman whose fecal occult blood test was positive at a medical checkup presented to our hospital. Esophagogastroduodenoscopy revealed multiple flared Yamada type II polyps in the whole stomach and segmented polyps at the greater curvature of the cardia and at the lesser curvature of the angular notch. Chest and abdominal CT scan showed dilatation of the whole stomach and thickening of the mucous membrane. From these findings, juvenile polyposis localized in the stomach was suspected and we performed laparoscopic total gastrectomy + D1 lymph node dissection. Macroscopic study of the resected specimen revealed diffused polyposis in the whole gastric mucous membrane. Histopathology revealed dilatation of the glandular epithelium associated with interstitial edematous change, and mucus retention in the glandular space. Juvenile polyposis was thus diagnosed, and we identified five lesions of highly differentiated adenocarcinoma which retained within the mucosa.
This paper presents our case of juvenile gastric polyposis for which laparoscopic total gastrectomy was performed, together with some bibliographic comments.
