目的：探讨急性胰腺炎累及乙状结肠系膜的多层螺旋CT表现及其解剖学基础。方法回顾分析60例行腹腔和盆腔CT增强扫描且符合Balthazar CT分级C级及其以上的急性胰腺炎患者的临床和CT资料，着重观察记录乙状结肠系膜的改变，并计算胰腺炎症的CTSI评分。结果①乙状结肠系膜受侵19例，表现为系膜水肿密度增高，局部系膜血管边缘模糊不清；乙状结肠间隐窝液体积聚7例；②60例患者中，CTSI评分在4～5分者20例，～7分者24例，～10分者16例；③乙状结肠系膜受侵和乙状结肠间隐窝积液情况与急性胰腺炎的CTSI评分无相关性（P＞0．05）。结论MSCT可充分显示急性胰腺炎累及乙状结肠系膜的解剖细节。

Objective To evaluate the MDCT features and anatomic bases of mesosigmoid involvement in acute pancreatitis . Methods CT images of sixty cases with acute pancreatitis were reviewed retrospectively ,which were proved by surgery or clinical and labora-tory findings.Emphasis was placed on the CT features and its pathway of mesosigmoid infiltration .Results ①The CT appearance of mesosig-moid involvement was presented as edema ,thickening,misty density,and blur margin of the mesenteric vessels ,with or without fluid collection in the intersigmoidal recess.②Among the 60 patients,20 patients belong to the group which the CTSI was 4~5,24 patients belong to the group which the CTSI was 6~7,and 16 patients belong to the group which the CTSI was 8~10.③The frequency of mesosigmoid involvement and fluid collection in the intersigmoidal recess had no positive relationship with the CTSI (P>0.05).Conclusion The CT images can show the involvement of the mesosigmoid in detail .
