Abstract

Purpose: Intussusception is one of the most common causes of an acute abdomen in infancy. The majority of pediatric cases of intussusception are of the ileocolic type and usually idiopathic. Small bowel intussusception is rarely diagnosed in children, and few cases have been reported. The purpose of this study was to determine the clinical features and causes of small bowel intussusception in children. Methods: We retrospectively reviewed the clinical and radiologic findings of 21 children with small bowel intussusception who were admitted to Seoul National University Children's Hospital between March 2005 and January 2010. Results: The clinical presentation of small bowel intussusception included abdominal pain or irritability (85%), vomiting (23%), fever (14%), bloody stools (14%), and abdominal masses (4%). Six patients required surgical management. Ultrasonography showed that the mean diameter of the lesions and mean thickness of the outer rims were 1.6${\pm}$0.7 and 1.7${\pm}$1.8 mm, respectively. Eleven lesions were located in the left abdominal or paraumbilical regions. Children who underwent surgical management were older than children with transient small bowel intussusception (mean age, 51 vs. 109 months). The mean diameter of the lesions and mean thickness of the outer rims were greater in the surgically-managed group. The location of intussusception was not significantly different between the two groups. Conclusion: Small bowel intussusception was spontaneously reduced in a large number of pediatric patients. However, sonographic demonstration of larger size, older age, and pathologic lead point warrant surgical intervention.

목 적: 장중첩증은 영아기 급성 복통의 흔한 원인 중 하나로 대부분 특발성의 소장-대장형이다. 반면 소장형 장중첩증은 드물며 시작점을 보이는 경우가 있고 수술적 정복을 필요로하는 경우가 흔하다. 본 연구의 목적은 소아에서 소장형 장중첩증의 임상 양상과 경과에 대해 알아보고자 한다. 방 법: 2005년에서 2010년까지 서울대병원에서 소장형 장중첩증으로 진단받은 21명의 환아들의 임상 양상 및 영상 소견을 후향적으로 분석하였다. 결 과: 임상 양상은 복통 및 보챔(85%), 구토(23%), 발열(14%), 혈변(14%) 및 복부 종괴(4%) 등이었다. 여섯 명(28%)의 환아에서 수술적 치료가 필요하였다. 초음파에서 병변의 직경은 1.6${\pm}$0.7 cm였고 가장자리의 두께는 1.7${\pm}$1.8 mm였다. 열한 명에서 병변이 왼쪽 복부 혹은 배꼽 주위였다. 수술적 치료가 필요했던 환아들은 자연 정복된 환아들에 비해 평균 연령이 높았다(109${\pm}$17개월: 51${\pm}$20개월). 병변의 평균 직경 및 가장 자리의 두께는 수술적 치료가 필요했던 환아들에서 더 큰 소견을 보였고 위치는 두 그룹 간에 차이를 보이지 않았다. 결 론: 소장형 장중첩증은 많은 소아에서 자연 정복된다. 그러나 초음파에서 크기가 크고, 나이가 많을수록 또한 병변의 시작점이 있으면 수술적 치료를 고려할 수 있다.
