Aim:
To analyze the clinical presentation, pathological aspect and treatment of gastric adenomas.
Patients And Methods:
Retrospective analysis of 75 patients aged 26 to 88 years in whom a gastric adenoma was diagnosed.
Result:
Seventy one patients had elevated endoscopical lesions and two had depressed or flat lesions. Ninety percent of lesions were located in the gastric antrum. Pathological study detected 6 focal carcinomas within the adenomas and 5 concomitant carcinomas located elsewhere in the stomach. Fifty four patients were subjected to endoscopical resection. Among patients with focal carcinomas, a gastrectomy was performed in four and endoscopical resection in two.
Conclusions:
Gastric adenomas must be considered in the differential diagnosis of gastric elevated lesions and may be confused in early gastric cancer. There is a histological resemblance between adenomas and gastric dysplasia described by several authors though only in our cases and in the Japanese literature the adenoma is referred to as mostly a polypoid sessile lesion.
