儿童急性阑尾炎的CT表现及其评价

目的：探讨儿童急性阑尾炎的CT表现及其诊断价值。方法：回顾性分析本院2007年1月～2008年12月经手术和病理证实的55例小儿急性阑尾炎的临床和CT资料,总结其CT表现特点和临床应用价值。结果：55例急性阑尾炎中,卡他型12例,化脓型25例,坏疽型18例。CT表现为阑尾肿胀增粗（37/55）;阑尾腔内肠石（35/55）;阑尾腔内积气（17/55）;阑尾穿孔并周围脓肿形成（18/55）;阑尾周围组织密度不均匀升高（19/55）;相邻盲肠壁增厚（24/55）;腹水（11/55）;肠梗阻（5/55）;其它还有肝脓肿、NEC等并发症形成。结论：儿童急性阑尾炎的CT表现具有一定特点,CT检查可显示阑尾及其周围组织结构的病理改变,为临床明确诊断提供客观依据,尤其适用于儿童。

Manifestations and Diagnostic Value of CT in Acute Appendiatis in Children

Objective： To study the manifestations and diagnostic value of CT in acute appendicitis in children. Methods：Retrospective analysis was made of the clinical and CT data of 55 cases of surgically and pathologically confirmed acute appendicitis in children from January 2007 to December 2008, summing up their CT features and clinical value. Resuits： In the 55 cases of acute appendicitis, 12 cases were of catarrhal type,25 cases of suppurative type and 18 cases of gan grene type. CT manifestations were as follows： swelling enlarged appendix （37/55） ;appendieeal intraluminal feealith （35/ 55） ; appendiceal intraluminal gas （ 17/55 ） ; appendiceal perforation and abscess formation （ 18/55 ） ; inhomogeneous in creased density of periappendiceal tissue （19/55）;adjacent cecal wall thickening （24/55）;ascites （11/55）;ileus （5/55）;and its complications such as liver abscess and NEC. Conclusion： CT manifestations of acute appendicitis in children have their own characteristics. CT examination can show the pathological changes of appendix and surrounding tissues, providing an objective basis for clinical diagnosis.
