Histological Comparison of Endoscopic Forceps Biopsy with Endoscopic Resection in Gastric Mucosal Elevated Lesion / 대한소화기내시경학회지

ABSTRACT

BACKGROUND/AIMS: The correct histological diagnosis of gastric adenoma is important, because it has been reported to be precancerous lesion and associated with focal gastric carcinoma. However, there is some discrepancy between the histology of the forceps biopsy and that of the endoscopic resection. In this study, we compared the histologic findings of gastric mucosal elevated lesion between the specimens of forceps biopsy and endoscopic resection. METHODS: We reviewed retrospectively 137 cases of gastric mucosal elevated lesion which had been removed by the resection such as polypectomy or endoscopic mucosal resection. All patients had undergone forceps biopsy before endoscopic resection. We compared the histologic findings of the specimens by forceps biopsy with those by resection. RESULTS: The histologic fidings were accordant at 101 of the 137 cases (73.7%), and different at 30 cases (21.9%). Among the 86 cases with adenoma in the biopsied specimens, 10 cases (11.6%) were finally diagnosed as gastric cancer in the resected specimens. CONCLUSIONS: Because biopsy specimens may not be presentative of the entire lesion, endoscopic resection of gastric mucosal elevated lesion is needed for accurate histologic diagnosis and treatment if adenoma is suspected.
