Abstract

After clinical and laboratory tests of a 12-year-old warmblood horse (castrated male, 540 kg) displaying symptom of pain, a diagnosis of intestinal obstruction due to foreign substances like sand was made and an abdominal section and enterotomy were conducted to confirm and extract the intestinal stone (enterolith) on the right dorsal part of the ascending colon. The extracted intestinal stone was around 2.9 kg and greenish brown rugby ball sized ($22cm{\times}10cm$) stone. Analysis of the element components (EDX) using a scanning electron microscope revealed percentages of C (30.08%), O (39.85%), Mg (3.89%), P (11.15%), and Ca (11.16%) at a magnification of 400. This was the first example of a successful extraction and treatment of intestinal stone in a horse domestically and thereby has its significance.

산통 증상을 보인 12세된 웜블러드(거세, 540 kg) 말로부터 임상검사 및 실험실 검사결과 모래 등 이물에 의한 장폐색으로 진단하여 개복술과 장절개술을 실시한 결과 장결석을 확인하여 적출하였다. 적출한 장결석은 약 2.9 kg, 녹갈색, 럭비공 크기($22cm{\times}10cm$)였다. 주사전자현미경(FE-SEM, Hitachi S-4300모델)을 이용하여 원소성분(EDX)을 분석한 결과 400배율에서 C(30.08%), O(39.85%), Mg(3.89%), P(11.15%), Ca(11.16%)가 높게 나타났다. 국내 말에서 크기가 가장 큰 장결석 적출 및 치료가 성공적으로 진행된 최초의 예로서 그 의의가 있다고 볼 수 있다.
