We herein report a rare case of intraductal papillary mucinous neoplasm with a pancreatogastric fistula in an elderly Japanese man admitted to our hospital. The pancreatogastric fistula was confirmed using endoscopic retrograde pancreatography via a cannulated guidewire placed in the stomach. Six months after admission, the patient was diagnosed with intraductal papillary mucinous carcinoma. A pancreatogastric fistula is generally a rare complication of intraductal papillary mucinous neoplasm. It was caused by mechanical penetration in this case. Interestingly, we also observed endoscopic and histochemical mucosal changes in the fistula.

我们在此报告一例罕见的胰胃内瘘的胰胆管内乳头状黏液性肿瘤病例，该患者为老年日本男性，因该疾病入住我院。通过放置在胃中的带套管导丝进行内镜逆行胰胆管造影术，可确认胰胃内瘘的存在。入院 6 个月后，患者被诊断为胰胆管内乳头状黏液性癌。胰胃内瘘通常是胰胆管内乳头状黏液性肿瘤的罕见并发症。在本例中，它是由机械穿透引起的。有趣的是，我们还观察到瘘管处的内镜和组织化学黏膜变化。
