Heterotopic gastric mucosa in the duodenal bulb was detected by endoscopic examination in 25 adult patients and was confirmed by biopsy in 17 of these patients. The endoscopic findings were correlated with the radiographic features of the lesion on upper gastrointestinal barium studies. On radiographs, this entity usually presented as clusters of 1- to 3-mm plaques raised above the smooth and featureless duodenal mucosa; this was seen in 17 (68%) of 25 patients. A less frequent finding was patches of coarse nodular mucosa with superficial erosions or an ulcer crater (five cases [20%]). The heterotopic gastric mucosa was visible as polypoid masses in two patients and as prominent areae gastricae covering the base of duodenal bulb in another.
通过内镜检查在25例成年患者中检测到十二指肠球部异位胃黏膜，其中17例经活检证实。内镜检查结果与上消化道钡餐检查中病变的影像学特征相关。在X线片上，该病变通常表现为高出光滑无特征的十二指肠黏膜的1至3毫米斑块簇；25例患者中有17例（68%）出现这种情况。较少见的表现是粗糙的结节状黏膜斑伴浅表糜烂或溃疡灶（5例[20%]）。2例患者的异位胃黏膜表现为息肉样肿块，另1例表现为覆盖十二指肠球底部的明显胃小区。
