目的 探讨小儿术后肠套叠病因、临床特点及误诊原因。方法 回顾性分析 9例术后肠套叠原发疾病 ,发生梗阻与再手术的时间及临床症状和体征。结果 9例均为小肠套叠 ,其中回回套 4例 ,空空套 2例 ,空回套 3例。套叠长度为 10～ 2 0cm ,超过 2 0cm 1例 ,全部套叠均无肠坏死。再手术后 3例切口感染 ,均痊愈。结论 术后肠套叠发病原因仍不清楚 ,公认与肠功能紊乱有关。 2岁以内多见 ,套入的长度与病程时间不成正比 ,很少发生肠坏死。临床上症状、体征与原发性肠套叠不同 ,很少有血便 ,B超检查无包块。诊断困难 ,一旦发生 ,不能自行解套 ,应早期剖腹探查。
Objective To investigate the causes, clinical features and causes of misdiagnosis of intussusception in children. Methods Retrospective analysis of 9 cases of intussusception primary disease, obstruction and reoperation time and clinical symptoms and signs. Results Nine cases were all intussusception, in which 4 cases were returned, 2 cases were empty and 3 cases were empty. Nesting length of 10 ~ 20cm, more than 20cm in 1 case, all without necrosis. 3 cases after incision infection, were cured. Conclusions The causes of intussusception after surgery is still not clear, is generally associated with intestinal disorders. More common within 2 years of age, the length of the sleeve is not proportional to the duration of the disease, rarely occurs intestinal necrosis. Clinical symptoms, signs and primary intussusception different, very few bloody stools, B ultrasound examination without mass. Diagnosis is difficult, in the event, can not relieve themselves, should be an early exploratory laparotomy.
