Mucin-producing bile duct tumor is a rare biliary tract tumor. Despite the development of modern diagnostic technologies such as ultrasonography, and angiography, the precise determination of this tumor is difficult because of ambiguity caused by the abundant mucin secreted by the tumor and/or by the superficial mucosal spread of the tumor along the bile duct. Given these problems, selective percutaneous transhepatic biliary drainage (PTBD) and percutaneous transhepatic cholangioscopy (PTCS) are indispensable for the accuracy staging of this cancer. But, PTCS has a risk of a rare but serous complications, seeding metastasis at the sinus tract of PTBD, whereas the retrograde approach minimizes this risk. We report the case of a patient who underwent the successful resection of a mucin-producing bile duct tumor. The tumor was diagnosed preoperatively as originating in the left caudate lobe after ERC and peroral cholangioscopy (POCS).
黏液生成性胆管肿瘤是一种罕见的胆道肿瘤。尽管有超声检查和血管造影等现代诊断技术的发展，但由于肿瘤分泌的大量黏液以及肿瘤沿胆管的浅表黏膜扩散所导致的模糊性，精确诊断这种肿瘤仍很困难。鉴于这些问题，选择性经皮经肝胆道引流（PTBD）和经皮经肝胆道镜检查（PTCS）对于该癌症的准确分期必不可少。但是，PTCS有发生一种罕见但严重并发症的风险，即PTBD窦道种植转移，而逆行途径可将这种风险降至最低。我们报告了一例成功切除黏液生成性胆管肿瘤的患者病例。该肿瘤在术前经内镜逆行胰胆管造影（ERC）和经口胆道镜检查（POCS）后被诊断为起源于左尾状叶。
