연령에 따른 장중첩증의 임상양상 및 치료에 대한 비교분석 = A Comparative Analysis of Clinical Features and Treatment Outcomes of Intussusception according to Age Distribution

국문 초록 (Abstract)

목 적: 장중첩증으로 진단받았던 환아들을 연령군으로 나누어 임상증상 및 치료 결과를 비교하여 향후 장중첩증의 진단과 치료에 도움을 주고 연구를 시행하였다. 방 법: 2000년자 1월부터 2004년 5월까지 포천중문의대 분당차병원 소아과 및 외과학교실에서 장중첩증으로 진단된 159명 환아를 대상으로 연령군에 따라 후향적으로 연구하였다. 5개월 미만 군을 I군, 5~11개월 군을 II군, 12개월 이상 군을 III군으로 정하였으며, 연령, 성별 및 계절적 분포, 원인, 임상 증상, 방사선소견, 장중첩증의 유형, 수술방법, 재발률에 대하여 비교분석하였다. 결 과: 주요 임상증상 및 징후를 세 군에서 비교하였을 때 주기적인 보챔 증상은 세 군 모두에서 가장 흔한 증상이었다. 보챔 증상과 동반된 구토는 I군에서 통계적으로 유의하게 높았으나(p<0.05), 혈변의 경우 나이가 많은 III군에서 더 높은 빈도를 나타냈다(I군: 66.7%, II군: 75.4%, III군: 77.9%). 증상 발현 후 장중첩증으로 진단될 때까지 걸린 경과시간은 각 군에서 평균 21시간, 20시간, 22시간으로 세 군 사이에 별다른 차이가 없었으나 증상 발현 후 48시간 이후에 진단된 환아는 어린 연령인 I군에서 통계적으로 유의하게 많았다(I군: 23.8%, II군: 4.9%, III군: 7.8%). 단순 복부 방사선 촬영상 I군에서 장폐쇄소견이 타군에 비해 유의한 차이를 보였다(p<0.05). 치료는 일차적으로 바륨 정복술을 시도하였으며 실패율은 I군 52.4%, II군 26.2%, III군 14.3%로 I군에서 유의하게 높았다. 결 론: 나이가 어린 군에서 증상이 뚜렷하지 않아 진단이 늦어지고 그로 인해 수술적 치료 결과가 많았다. 따라서 나이가 어린 영아에서는 보챔과 동반되는 구토 증상이 있을 때 장폐쇄에 대한 보다 적극적인 검사 및 세심한 관찰로 진단이 지연되지 않도록 장중첩증을 항상 감별하는 것이 필요할 것으로 생각된다.

Purpose: We divided the children diagnosed with intususception into three different age groups and compared the clinical symptoms and treatment outcomes in order to analysis diagnosis and treatment of Intusussception. Methods: A retrospective chart review was established of 159 patients diagnosed with intussuception who had been admitted to Department of Pediatrics and General Surgery, Bundang CHA hospital from January, 2000 to May, 2004. We divided the patients into three groups, according to their age. Those who were under five months of age (group I; 21 patients), those between 5~11 months of age (group II; 61 patients), and those older than 11 months of age (group III; 77 patients). Then we compared the age, sex, seasonal distribution of occurrence, the cause, the clinical features, radiologic review, the type of intusussception, surgical methods, recurrence rate and treatment outcomes, among these three groups. Results: On comparing the clinical symptoms and signs among the three groups, the most common major clinical symptom and sign was irritabiltity in all three groups. Vomiting with irritability was statistically more common in group I (p<0.05) and bloody stool was most frequent in group III. The average time taken until a diagnosis was made after the symptom onset was, 21 hours in group I, 20 hours in group II and 22 hours in group III. Which showed no significant difference. But there was a higher rate of delayed diagnosis in group I, which took over 48 hours until the diagnosis was made (group I; 23.8%, group II; 4.9%, group III; 7.8%). Simple abdominal X-rays showed more frequent instances of intestinal obstruction in group I (p<0.05). The primary treatment done was barium enema which showed a failure rate of 52.4% in group I, 26.2% in group II and 14.3% in group III. Showing the highest failure rate in group I. Conclusion: The youngest group had vague symptoms which lead to delayed diagnosis and more frequent surgical procedures. As so, we advocate the importance of further evaluation and close observation, considering intussusception in children with symptoms of irritability and vomiting, especially in the early infant group.
