目的

探讨阑尾套叠的特征和诊治方法。

方法

回顾1990 年1 月至2006 年12 月收治的5 例阑尾套叠患者的临床资料，结合文献报道，就该病特点及诊治经验进行探讨。

结果

本组2 例表现为定位不明确、反复发作绞窄性腹痛；2 例表现为急性阑尾炎症状；1 例腹部可触及包块。5 例患者中2 例术前行腹部B 超检查，腹部X 片检查3 例，纤维结肠镜检查1 例。所有病例均行手术治疗，术中发现阑尾套叠，4 例行阑尾切除术，1 例行常规阑尾切除及盲肠壁修补术。 术后5 例患者痊愈出院。

结论

阑尾套叠是一种非常少见的疾病，其临床表现多变，术前很难作出诊断；纤维结肠镜检查能够协助诊断，但是常误诊为盲肠息肉而摘除，引起肠瘘，甚至休克死亡；手术是主要的治疗方法。

Objective

To study the clinical characteristics and the methods of diagnosis and treatment for appendiceal Intussusception.

Methods

The clinical data of 5 patients with appendiceal Intussusception treated from January 1990 to December 2006 were analyzed.

Results

The clinical manifestations included vague，recurrent，cramping abdominal pain in 2 cases，2 cases potential to mimic acute appendicitis and abdominal mass in 1 cases.Of the 5 cases，ultrasound examination were performed in 2 cases，simple abdominal radiography in 3 cases and colonoscopy in 1 case.All the cases undervent operations which showed appendiceal Intussusception.

Conclusions

Appendiceal Intussusception is rare.It is more difficult to make right diagnosis preoperatively.Colonoscopy may be facilitated in preoperative diagnosis.It is important for the endoscopist to remember that the appendiceal intussusception may mimic a cecal polyp and avoid endoscopic removal and the potential hazards.Surgery was the first choice of therapy.
