To investigate tumor extension to the main pancreatic duct in patients with intraductal papillary mucinous tumors, we conducted pancreatoscopy assisted by endoscopic sphincter dilation (ESD). Two patients with intraductal papillary mucinous tumors were included in this study. The endoscopic sphincter dilation was performed using an Olbert balloon-tipped catheter. A mother-baby scope system was used for endoscopic examination. After dilation of the orifice, the babyscope was inserted smoothly. Tumorous lesions (especially the typical salmon-roe appearance of the tumors) were clearly observed in the main pancreatic duct in one patient, while no tumorous lesions were identified in the other patient. The ESD procedure may be applicable for assisting insertion of the endoscope through the papilla of Vater into the pancreatic duct. ESD is useful both for treating and for diagnosing pancreatic lesions.
为了研究导管内乳头状黏液性肿瘤患者肿瘤向主胰管的扩展情况，我们在内镜括约肌扩张术（ESD）辅助下进行了胰管镜检查。本研究纳入了两名导管内乳头状黏液性肿瘤患者。使用奥尔伯特球囊导管进行内镜括约肌扩张。采用子母镜系统进行内镜检查。扩张开口后，顺利插入子镜。在一名患者的主胰管中清晰观察到肿瘤性病变（尤其是肿瘤典型的鲑鱼籽样外观），而在另一名患者中未发现肿瘤性病变。ESD操作可能适用于辅助内镜经十二指肠乳头插入胰管。ESD对胰腺病变的治疗和诊断均有用。
