5일령 한우 송아지가 식욕부진, 배변불능, 침울, 복부팽만으로 내원하였다. 결장폐쇄로 잠정진단하고 폐쇄 부위와 양태를 확인하기 위해 단순촬영과 조영촬영을 실시하였다. 단순촬영상에서 대장이 가스로 확장되어 있었으나 하행결장 내에 변은 존재하지 않았다. 조영촬영상에서는 조영제가 집적된 끝 부분이 확장된 결장내로 돌출해 있고 조영제가 모여 있는 중간 부위는 좁아져 있었다. 이들 소견은 부검에서 확인된 확장된 나선결장과 위축된 원위결장 사이의 점막성 폐쇄를 잘 설명해주었다. 방사선 조영촬영은 결장폐쇄의 위치 및 양태 확인에 효율적이라 판단된다.
A 5-day-old male Korean native calf was referred with the primary complaint of anorexia, absence of feces, depression, and abdominal distention. Although this case was tentatively diagnosed as atresia coli, plain and contrast radiography was performed to confirm site and appearance of obstruction. A plain radiograph revealed gas distension in the large intestine, with absence of fecal material in the descending colon. In a contrast radiograph, the blind part of descending colon that was accumulated with contrast media smoothly protruded to distended colon with gas and the middle part was seen as narrow. These findings were well corresponded with the mucosal blockage junction between distended spiral loop with gas and descending colon that was hypoplasia or atropy in necropsy. In conclusion, contrast radiography was considered very useful method to identify the site and type of obstruction in diagnosis of atresia coli.
