摘　　要：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BalthazarCT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 involvemenl ill acute pancreatitis. Methods CT images of sixty cases with acute pancreatitis were reviewed retrospec.tively ,which were proved hy surgery or elinical and labora- tory. findings. Emphasis was placed on the CT features and its pathway of mesosigmnid infihration. Results ①The CT appearance of mesosig- mold involvement was presented as edenm,thickening, misty density, and hlur margin of the mesenteric vessels, with or without fluid collection in the intersigmoidal recess. ②Among the 60 patients,20 patients belong to the group whictl the CTSI was 4 -5,24 patients behmg to the group which the CTSI was 6 - 7 ,and 16 patients belong to the group which the CTSI was 8 - 10. @The frequency of mesosigmnid inw^lvement and fluid collection in the intersigmoidal recess had no positive relationship with the CTSI （ P 〉 0.051. Conclusion The CT images can show the involvement of the mesosigmoid in detail.
