小儿肠套叠的影像诊断与空气灌肠整复失败的分析

目的：提高对小儿肠套叠的影像诊断与治疗的认识，方法：回顾性分析近15年来经空气灌肠证实的肠套叠患儿608例的影像学表现。其中550例经透视下行结肠注气整复成功，58例整复失败经手术复位。结果：空气灌肠整复失败58例中，术后病理证实有复杂型28例，器质性肠套叠2例，肠壁损伤21例，3例阑尾被套，4例肠坏死，其中回－回－结套24例，回结套24例，回回结结型4例，结论：透视下空气灌肠是诊断与治疗小儿肠套叠的最好方法，对于复杂型肠套叠及伴有肠管畸形，肠腔坏死等症，则应尽早采取手术治疗。

Fifty-eight unreduced cases were cured by operation . The X-ray findings in all 608 cases in the past 15 wars were analyzed and reviewed. Results: Successful operation was done in 58 cases unsuccessful by air enema , which included complex intussusception ( n = 28) , organic intussusception ( n = 2), intestinal injury ( n=21), involvement of appendix ( n = 3) and bowel necrosis was seenin 4 cases. Proved by operation pathology, ileoilecolic intussusception in 24 cases. Conclusion:Air-pressure enema examinations is the best methods in treat and diagnose intussusception .
