ABSTRACT

A question frequently asked by clinicians who are treating small animals suspected of having gastrointestinal foreign bodies is whether one imaging test such as survey radiography or ultrasonography is sufficient to make the diagnosis. A study was undertaken to try and answer this question. Survey abdominal radiography and ultrasonography was performed on 16 small animals (11 dogs, five cats) with clinical signs of an obstruction because of a confirmed gastrointestinal foreign body. The majority of the foreign bodies (14/16) were confirmed by surgical removal and were located in the small intestine. A gastric foreign body was retrieved endoscopically and a colonic foreign body was passed in the feces. Radiographically identifiable foreign bodies were evident in nine animals. Small intestinal overdistension was present radiographically in seven animals. Ultrasonography detected a foreign body in all 16 animals. The foreign bodies were identified by their distal acoustic shadowing and variable degrees of surface reflection. An intestinal perforation was detected sonographically but not radiographically. The value of additional sonographic findings including thickening of the gastrointestinal wall and loss of layering, free peritoneal fluid, and lymphadenopathy in these animals is discussed. The findings in this series suggest that in a small animal with a gastrointestinal foreign body, ultrasonography alone could be used to make the diagnosis and may be a more appropriate choice than survey radiography.

  • 以為這篇沒放圖就不難嗎?
    看來這位低調的醫生,
    也未免太~高調了吧!(愛放很難的文)
    完全沉浸在自己愛的醫療領域......

    不過照這篇「沒圖」的定義來看,
    內容應該是「話唬×」的厚?是不是啊醫生?
  • 是話x爛沒錯︿︿

  • 梅干
  • 肯定是超音波呀

    因為詹醫師是超音波控。。。
  • 除此之外,真是超音波唷^^

  • 可以從初級班開始教咩?
    比方:勒森萬~超音波的原理與實地應用
    勒森吐~超音波優缺點(某控:沒有缺點!?)
    勒森酥力~論超音波取代X光的可能性

    諸如此類,這樣大家可以學東西又比較有梗迴響,造福蒼生功德無量善哉善哉~
  • 哈哈哈~
    好啊我試試~
    不過確定有梗迴響@@?

  • 有圖有真相*__*
    真相很難懂,只有醫生懂!
    我們都不懂,有看沒有懂!
  • 醫生也不懂,為何沒人懂!

  • 不懂就不懂,何苦要裝懂!
    就算裝很懂,一樣沒有懂!
  • 管他看懂不看懂
    多看幾次就會懂

  • Macovski
  • 醫生是很有潛力的,
    至於是不是真的有梗迴響,
    大家加油,好嗎?(小胖老師附身)
  • 好~(一起喊)

  • 黃靚輪
  • 用一句成語形容目前的情況呢,
    就是
    教不懂,師之過、學海無涯、三貓行必有我師。(好像不只一句)
  • 好像不是成語= =

  • 三
  • 對啊,真的不是成語(附議),
    前面兩句源自三字經(是真的三字經!)
    第三句只能說回頭是岸啊~
    至於第四句,我家的貓還在舉行三巨頭會議,
    還沒討論出來......>__<
  • 黃靚輪
  • 三隻小豬都是成語可以啦!
    不然就依觀眾要求改成:回頭是岸、回心轉意、回春妙手、回味無窮、回光返照、回生起死、回教不吃豬肉啦(新加坡人大暴走中)!
