摘要
目的 :评估胆管内超声检查 (IDUS)对胆管狭窄病因和分型的诊断价值。方法 :采用OlympusUM -G2 0 - 2 9R微型探头 (频率 2 0MHz)对 4 0例胆管狭窄病人于ERCP术中行胆管内超声 ,其中胆管癌 2 2例 ,胰头癌侵犯胆管 12例 ,胆管炎性狭窄 6例。结果 :胆管狭窄的IDUS分型为 1型 6例 ,2a型 1例 ,2b型 7例 ,3a型 2 1例 ,3b型 5例。良性狭窄 (胆管炎 )IDUS声像图特征为胆管壁肥厚、管腔狭窄伴壁内回声不均匀 ;恶性狭窄 (胆管癌、胰头癌侵犯胆管 )的IDUS图像特征为胆管壁肥厚、胆管外层高回声层不规则断裂。结论 :IDUS对明确胆管狭窄的原因和分类有一定价值。
Objective: To evaluate the value of intraductal ultrasonography (IDUS) in the diagnosis and classification of bile duct stenosis. Methods:IDUS was carried out in 40 patients with bile duct stenosis during ERCP by using Olympus UM-G20- 29R microprobe (20 MHz), among whom there were 22 cases of bile duct cancer, 12 cases of pancreatic cancer invading bile duct and 6 cases of inflammatory billiary strictuve. Results: Bile duct stenosis was classified as type 1 in 6 cases, type 2a in 1 case, type 2b in 7 cases, type 3a in 21 cases, and type 3b in 5 cases by IDUS. The IDUS image of benign bile duct stenosis (cholangitis) was characterized by thickening of bile duct, stricture of bile duct with irregular-echo in-duct while in malignant stenosis (bile duct cancer, bile duct invaded by pancreatic cancer), it was characterized by thickening of bile duct, irregular interruption of hyperechoic out-layer. Conclusions: IDUS has great clinical value in diagnosis and classification of bile duct stenosis.
