Abstract

Purpose: Since there are few studies involving acute pancreatitis in children, we reviewed our experience with this medical condition to describe the clinical features. Methods: A retrospective analysis was conducted by reviewing the medical records of 41 patients with AP who were admitted to the Department of Pediatrics of Pusan National University Hospital between January 1996 and June 2007. Results: Twenty males and 21 females (mean age, 8.7${\pm}$4.5 years) were included. In 22 patients (53.7%), no definitive causes were found. The most common etiologies were choledochal cysts (22.0%). Necrotizing pancreatitis was diagnosed in 5 patients (12.2%), and recurrent acute pancreatitis in 4 patients (9.8%). CT findings included pancreatic swelling (43.9%), peripancreatic fluid collection (29.3%), ascites (24.4%), and peripancreatic fat necrosis (12.2%). Serum amylase and lipase levels at diagnosis were 535.3${\pm}$553.2 and 766.2${\pm}$723.6 U/L, respectively, and were normalized within 1 week in 22 and 14 patients, respectively. On the basis of the Balthazar scale, 2 patients were diagnosed with severe AP. In 4 patients (9.8%), a surgical procedure was indicated. Major complications included ascites (32.3%), sepsis (16.1%), and pseudocyst and renal impairments (12.9%). Two patients died from multi-organ failure. Conclusion: The etiologies of AP in children are varied. Most children have a single episode and a self-limited course. However, AP of childhood still carries significant morbidity and mortality. Early diagnosis, appropriate treatment according to disease severity, and management of complications are important.

목 적: 소아에서 급성 췌장염은 췌장을 침범하는 가장 흔한 질환으로 최근 발생 빈도가 증가하고 있다. 이 질환에 대한 보고가 많지 않아 임상적 특징을 알아보고자 본 연구를 시행하였다. 방 법: 1996년 1월부터 2007년 6월까지 부산대학교병원 소아청소년과에서급성 췌장염을 진단받았던 41명을 대상으로 의무 기록을 후향적으로 분석하였다. 급성 췌장염의 진단은 임상 소견, 혈청 amylase 및 lipase치의 상승 및 방사선 소견이 합당한 경우로 하였으며, 이 질환의 원인, 임상 소견 및 경과, 중증도 판정, 치료등을 분석하였다. 결 과: 남자가 20명, 여자가 21명이었고, 진단 시 평균 나이는 8.7${\pm}$4.5세였다. 증상 발현에서 진단까지의 기간은 7.0${\pm}$7.4일이었고, 내원 당시 주증상은 복통 37예(90.2%), 구토 24예(58.5%), 발열과 경구 섭취 불량이 각각 6예(14.6%)였다. 췌장염의 원인으로는 원인불명 22예(53.7%), 총담관낭 9예(22.0%), 췌담관 합류 이상 3예(7.3%), Henoch-schonlein 자반병과 유행성 이하선염이 각각 2예(4.9%)였고 그 외 분할췌장, 용혈 요독 증후군, 외상, 바이러스성 간염, 약물(L-asparaginase)이 각각 1예였다. 간질성 췌장염이 36예(87.8%), 괴사성 췌장염이 5예(12.2%)였고 재발성 췌장염이 4예(9.8%)였다. 방사선학적 소견은 췌종대 18예(43.9%), 췌장 주위 액체저류 12예(29.3%), 복수 10예(24.4%), 췌장 주위 지방괴사 5예(12.2%)였다. 진단 당시 혈청 amylase치는 535.3${\pm}$553.2 U/L, lipase치는 766.2${\pm}$723.6 U/L였고, 혈청 amylase 및 lipase치가 1주 내에 정상으로 회복한 경우가 각각 22예(59.5%), 14예(42.4%)였고, lipase치가 4주 이후에 정상화된 경우가 11예(26.8%)였다. 중증도 판정기준인 APACHE II, Ranson 기준, Balthazar 점수에서 대부분 경증에 해당하였다. 금식과 총정맥 영양이 전례에서 시행되었고, 금식 기간은 평균 13.1${\pm}$17.0일, 총정맥 영양 기간은 평균 8.2${\pm}$13.7일이었다. Octreotide는 8명(19.5%), Gabexate mesilate는 4명(9.8%)에서 투여되었고, 4명에서 조임근절개술이 시행되었다. 합병증으로는 복수(32.3%), 패혈증(16.1%), 거짓낭(12.9%), 신장장애(12.9%), 흉수, 십이지장 궤양, 혈성복막(6.5%) 등이 있었다. 34명이 완전 회복되었고, 2명(4.9%)이 췌장염의 합병증으로 사망하였다. 결 론: 소아 급성 췌장염은 드문 질환이 아니며 성인과는 다른 원인, 증상 및 경과를 보였다. 대부분 환자들이 수 일 이내 완전 회복되지만 아직 사망률이 높으므로 조기 진단과 발병 초기에 중증도를 평가하여 적절한 치료 및 합병증 관리가 중요하다.
