Abstract: Intestinal obstruction in cats is a disease characterized by intestinal dysfunction and difficulty in transporting contents. It is difficult to distinguish between mechanical obstruction and functional obstruction with low opacity. This case was a felis catus with a history of repeated vomiting. No obvious foreign body was found after plain X? ray，and linear intestinal foreign body was diagnosed by abdominal b ? ultrasound，and then surgical treatment was performed under the guidance of sterile urethral catheter. Postoperative b?ultrasound was used to monitor the intestinal recovery，diagnose functional obstruction caused by gastrointestinal inflammation and evaluate the intestinal healing at the operative site，providing a basis for subsequent treatment with a good prognosis.

摘要： 猫的肠梗阻是一种肠道机能障碍、导致内容物转运困难的疾病，临床上对机械性梗 阻和功能性梗阻的快速鉴别诊断存在一定难度。本病例为一只具有反复呕吐史的田园猫，在 拍摄X线平片后未见明显异物，通过腹部B超检查诊断为肠道线性异物，并进行了无菌导尿管 引导下的手术治疗。术后运用B超对肠道恢复情况进行监测，诊断胃肠道炎症导致的功能性 梗阻并评估了术部肠道的愈合情况，为后续治疗提供依据，预后良好。
