Abstract

Purpose: Severe abdominal distension is not uncommon symptom in the neonate. Two major causes of this symptom are benign transient intestinal ileus (BTII) and Hirschsprung`s disease (HD). But it is difficult to differentiate BTII from HD based on the symptoms and simple abdominal x-ray findings. The aim of this retrospective study was to assess the clinical aspects and diagnostic tests differencing two diseases. Methods: From August 2004 to March 2009, nineteen patients with severe abdominal distension, who underwent barium enema, anorectal manometry, and rectal suction biopsy (triple tests) due to a suspicion of HD, were enrolled. A comparison of clinical data associated with BTII and HD based on the clinical features and results of triple tests. Results: The age of onset of symptom was between 2 and 6 weeks in BTII and within 3 weeks in HD. On the barium enema, transitional zone revealed in 6 (50%) patients in BTII and 4 (57.1%) in HD. On anorectal manometry, the anorectal inhibitory reflex was present in 11 (91.7%) patients in BTII and 1 (14.3%) in HD. On rectal suction biopsy, ganglion cell was present in 9 (75%) patients in BTII and 0 (0%) in HD. Abdominal distension was improved within 3 months of life in all cases of BTII. Conclusion: We think that anorectal manometry may be more simple and useful diagnostic method than barium enema and rectal suction biopsy for differential diagnosis of transient intestinal ileus and Hirschsprung's disease.

목 적: 본 연구는 후향적으로 신생아기의 일시적 장폐쇄와 허쉬스프룽병에서 임상 양상과 검사법에 따른 결과의 비교를 통하여 양 질환의 감별 진단을 위한 검사법의 유용성을 알아보고자 하였다. 방 법: 2004년 8월부터 2009년 3월까지 심한 복부팽만으로 방문한 신생아 중 단순복부촬영을 하여 전체 장관의 심한 확장을 보이면서 직장에 공기 음영이 보이지 않아 바륨조영술, 항문직장압력 검사, 직장흡인 생검을 모두 시행한 19예를 대상으로 하였으며 이들을 일시적 장폐쇄군과 허쉬스프룽병군으로 분류하였다. 결 과: 총 19예 중, 일시적 장폐쇄군의 경우 남아 8명(66.7%), 여아 4명(33.3%)이었다. 발생 시기는 일시적 장폐쇄군은 출생 후 2주에서 6주, 허쉬스프룽병군은 출생 후 3주 이내였다. 바륨조영술에서 이행부위는 일시적 장폐쇄군 6예(50%), 허쉬스프룽병군 4예(57.1%)에서 관찰되었다. 항문직장압력 검사에서 항문직장억제 반사가 관찰된 경우는 일시적 장폐쇄군 11예(91.7%), 허쉬스프룽병군 1예(14.3%)였다. 직장 흡인 생검에서 신경절세포가 관찰된 경우는 일시적 장폐쇄군 9예(75%), 허쉬스프룽병군 0예(0%)였다. 복부팽만의 호전 시기는 생후 1개월 이전 1예(8.3%), 1~2개월 8예(66.7%), 2~3개월 3예(25.0%)였으며, 전례가 3개월까지는 복부팽만이 호전되었다. 결 론: 생후 2주 이후에 심한 복부팽만이 나타나는 경우, 허쉬스프룽병과의 감별을 위해 바륨조영술보다 먼저 항문직장압력 검사를 시행하고 항문직장억제 반사가 없거나 불확실한 경우에 선별적으로 직장 흡인 생검을 하는 것이 불필요한 검사를 줄이는데 도움이 될 것으로 생각된다.
