The purpose of this study is to examine the usefulness of intraductal ultrasonography at a frequency of 20 or 30 MHz in the diagnosis of mucin-producing tumor. The subjects were 66 patients with mucin-producing tumor (10 with main pancreatic duct type tumor and 56 with branch type tumor) who had also undergone endoscopic ultrasonography. In main pancreatic duct type tumors, we could diagnose the extent of the tumor and evaluate the invasion of the tumor into the pancreatic parenchyma in all seven patients who had undergone resection (three invasive tumors, four noninvasive tumors). Sixteen of 32 resected branch type tumors showing mural nodules with intraductal sonography were carcinoma or adenoma. On comparing intraductal and endoscopic ultrasonography in the rate of detecting nodules, in five tumors (one carcinoma and four adenomas), nodules were detected only with intraductal ultrasonography. In conclusion, intraductal ultrasonography is very useful for the diagnosis in the main pancreatic duct type tumor and in the detection of mural nodules in the branch type tumor.
本研究的目的是探讨20或30MHz频率的导管内超声检查在诊断产生黏液的肿瘤中的实用性。研究对象为66例产生黏液的肿瘤患者（10例为主胰管型肿瘤，56例为分支型肿瘤），这些患者均接受了内镜超声检查。在主胰管型肿瘤中，我们能够诊断出7例接受手术切除患者（3例浸润性肿瘤，4例非浸润性肿瘤）的肿瘤范围，并评估肿瘤对胰腺实质的浸润情况。32例经导管内超声检查显示壁结节的切除分支型肿瘤中，16例为癌或腺瘤。在比较导管内超声和内镜超声检测结节的率时，在5例肿瘤（1例癌和4例腺瘤）中，仅通过导管内超声检测到结节。总之，导管内超声检查在主胰管型肿瘤的诊断以及分支型肿瘤壁结节的检测中非常有用。
