Abstract
Endoscopic polypectomy has been performed for 581 lesions in 413 patients at our center during the past seven years. Among these patients there were ten gastric IFPs in nine patients, which is equivalent to 1.7%. We studied the endoscopic appearance and histopathological finding of the IFP cases. The results were as follows: 1) Gastric IFPs were frequently found at A-site (Table 2). The mucosal surface in these cases was smooth and appeared to be normal in color (Table 2, Figure 1). The features of the majority of gastric IFPs corresponded to Yamada's type III, few of them had local redness or white coating and none showed bleeding or bridging fold (Table 2, Figure 1). 2) Endoscopic polypectomy of gastric IFPs is very useful as a method of total biopsy, because it is difficult to diagnose gastric IFP based on specimens obtained by biopsy forceps. 3) It is suggested that gastric IFPs are mainly located at the deep portion of the mucosal layer or at the shallow portion of the submucosal layer and that they grow vertically in both directions (Figure 3-6).
