Vater壶腹部周围肿瘤54例诊断分析

目的探索有效的Vater壶腹部周围肿瘤的影响学诊断方法。方法回顾性分析2003年1月至2009年12月收治的54例Vater壶腹部周围肿瘤的临床资料。结果B型超声诊断符合率为31．5％,CT为61．1％,MRI55．6％,经内镜逆行胰胆管造影（ERCP）为100％,超声内镜（EUS）为95．0％,磁共振胰胆管成像（MRCP）为57．4％。B型超声与其他方法的诊断符合率差异有统计学意义（P〈0．05）。EUS与ERCP之间差异无统计学意义,但与其他方法的诊断符合率差异有统计学意义（P〈0．05）。CT、MRI、MRCP之间的诊断符合率差异无统计学意义（P〉0．05）。结论正确选择合适的检查方法及顺序,节约了时间和费用,减少了并发症,提高了手术的安全性和彻底性。

Imageology diagnosis of periampullary tumor

Objective To explore the early diagnosis of periampullary tumors. Methods The clinical data of 54 cases of periampullary tumor without obvious symptoms from January 2003 to December 2009 were retrospectively analyzed. Results The diagnosis accordance rate of B-ultrasound was 31.5 %, which Was significantly different from other imaging methods, including CT （61.1%）, MRI （55. 6 %） ,ERCP（100%） ,EUS（95.0 %） and MRCP （57. 4 %） （P〈0. 05）. There was no significant difference between EUS and ERCP, but their diagnosis accordance rate was significantly different from other imagings. There was no significant difference among CT, MRI and MRCP（P〈0. 05）. Conclusion The appropriate examination and sequence can save the time and expense, reduce the complication and increase the security of surgery.
