Abstract

Based on the results of previous studies, endoscopic biopsy sample's quality has a major impact on its adequacy for histopathology, and that the nature of the biopsy forceps can influence the specimen quality. The present study compared the effects of three different types of endoscopic biopsy forceps and two different operators on sample quality and adequacy for histopathology in three healthy cats. Every biopsy was performed between the major papilla and caudal duodenal flexure, and each operator performed five biopsies with each type of forceps on each cat, for a total of 90 biopsies. One pathologist evaluated the quality and adequacy of the obtained samples. Biopsies performed with large-cup forceps provided heavier and longer samples than the standard round forceps. With the same size forceps, the presence of alligator teeth had no effect on sample quality or adequacy for histopathological examination and assessment. Based on the results of the present study, although the standard round forceps could be used to obtain adequate samples for histopathology, large-cup forceps such as the standard oval and alligator jaw type have the advantage of obtaining high quality endoscopic samples.

본 연구는 고양이 십이지장에서 내시경적 조직 생검 시 사용된 다양한 겸자의 특징에 따른 조직의 질과 조직병리학적 적합성에 대해 평가하였다. 이러한 내시경용 생검 겸자에 따른 조직의 질과 적합성에 대한 연구는 인의에서 다수 보고되었으며 최근 개에서의 연구가 보고되었으나 고양이에서의 연구는 진행되지 않았다. 따라서 본 연구에서는 기존의 연구 결과와 고양이에서의 결과를 비교하여 그 차이를 확인하고자 하였다. 총 3마리의 건강한 고양이의 십이지장에서 3가지 종류의 생검 겸자를 사용하여 두 명의 실험자가 각각의 겸자 당 5 개씩의 시료를 채취하여 총 90개의 십이지장 점막 조직을 획득하였다. 획득한 조직은 각각 무게와 길이, 깊이, 부서진 인공구조, 조직병리학적 적합성에 대해 평가하였다. 내시경 생검용 겸자에 의한 조직의 질은 컵이 큰 겸자의 경우 더 무겁고 긴 조직을 얻는데 효과적인 결과를 얻었으며 이는 기존의 사람과 개에서의 연구와 비슷하다. 그러나 조직의 깊이와 부서진 인공구조, 특히 조직병리학적 적합성에 있어서는 겸자의 컵 크기나 모양에 따른 차이가 나타나지 않았으며 이는 기존의 연구와 다른 점이다. 하지만 조직학적 적합성이 있다고 평가된 조직들은 길이가 길고 인공구조가 적게 나타났으며 이러한 조직의 질은 겸자의 종류에 따른 차이를 보였다. 따라서 겸자의 종류는 조직의 질에 영향을 미치며 이는 간접적으로 조직학적 적합성과 관련이 있을 것으로 생각된다. 이를 바탕으로 고양이의 내시경적 생검 시, 비록 작은 컵의 겸자로도 조직병리학적으로 적합한 조직을 얻을 수 있지만 더 나은 질의 조직을 얻기 위해서 큰 컵의 겸자를 적용하는 것이 효과적인 것으로 생각된다.
