나이/성별 : M/3
주증상 : Abdominal pain
임상소견 :
진단명 : Intussusception

첫 번째 영상은 초음파 검사입니다. 중첩된 장벽의 부종에 의한 저에코층과 점막과 장간막에 의한 고에코층으로 인하여, 횡단 스캔상 저에고의 다중환상고리가 보여 doughnut sign 혹은 target sign 이라 합니다. 스캔 부위에 따라 같이 끼어든 장간막이 같이 스캔되면 초생달 모양의 고에코 부분이 내부에 관찰될 수 있습니다 (crescent-in-doughnut). 이때 장간막 림프절 또는 선행원인 병변이 같이 보일 수 있습니다. 종단 스캔상에는 콩팥 모양(psuedokidney sign) 또는 샌드위치 모양(sandwich sign)으로 나타납니다. 진단은 장중첩증입니다. 근위부 장관이 원위부 장관의 속으로 끼어들어가 장폐쇄를 일으키는 것으로 같이 말려들어간 장간막으로의 혈류장애로 인한 장관의 정맥성 울혈 내지 장괴사가 문제입니다. 특발성인 경우가 많지만, 신생아에서는 Meckel 게실이나 장중복(duplication), 5세 이상에서는 폴립, 종양 등 선행 원인 질환이 있을 가능성이 있으므로 유의해야 합니다. 단순복부촬영상 우측 복부의 공기 음영이 적으면서 장폐쇄 소견이 보일 수 있고, 종괴음영이 나타나기도 합니다. 단순복부촬영의 다른 중요성은 정복술 전에 정복술의 절대 금기 사항인 유리공기 (free gas)의 유무를 관찰하는 것입니다. 두 번째부터 네 번째 영상은 공기 정복술 (air reduction)시 시행한 단순 촬영입니다. 상복부에 종괴음영 이 있고 장폐쇄에 의해 소장이 늘어나 있습니다. 장천공, 장괴사, 복막염이 의심되지 않는 한 공기 또는 바륨 정복술을 시행하여 압력으로 감입부를 밀어내어 장중첩을 풀어줍니다. 현재 공기 정복술이 보편화된 시술로 foley catheter나 tape를 이용하여 항문으로 공기가 새지 못하게 한 후 장내압를 압력계로 모니터 하면서 120mmHg를 넘지 않는 범위에서 정복을 시도합니다. 투시하에 감입부가 밀려나오면서 소장내로 공기가 넘어가는 것 을 직접 볼 수 있습니다.
