【摘要】目的探讨成人肠套叠的临床特点和诊治原则。方法对1980年1月至2004年2月期间我院收治的167例成人肠套叠临床资料进行回顾性分析。结果术前确诊79例，占47.3%。167例中159例行手术治疗，其中116例为肠道肿瘤,良性48例，恶性68例； 余51例为手术或外伤后、肠道炎症、盲肠过长等。共有117例行肿瘤根治性切除术或相应肠段切除术，50例行单纯复位或复位后固定术。2例术后死亡，余均恢复良好，134例随访2个月～10年，无肠套叠复发。结论提高对成人肠套叠的认识是诊断的关键，检查应选用B超、CT、钡灌肠等，治疗则首选手术治疗。
ObjectiveTo improve the efficacy of colon doublecontrast barium enema examination by using digital gastrointestinal machine and modified enema techniques. MethodsSixtyfour patients were examined on digital remote controlled gyration table, with oral coloncleansing preparation and selfmade disposable plastic bag. Results In 64 patients, up to 93.8% were found with none or little fecal materials in the cecum and ascending colon. 80% of the results were scored excellent, and 95% were accurate for making diagnosis. All the patients underwent the examination successfully. ConclusionDigital gastrointestinal machine examination combined with modified hypotonic doublecontrast barium enema is a simple, convenient and efficient way to clearly demonstrate colonic mucosa, and help increase the detection and diagnosis rate.
