To report the clinicopathological findings and outcome in cats with pancreatitis-associated extrahepatic biliary tract obstruction (EHBO) treated by choledochal tube stenting.
Medical records of cats with EHBO secondary to pancreatitis that underwent choledochal stenting were reviewed. Information on outcome was obtained by re-examination of the cat or by telephone interview with the owners.
All cats had pancreatitis confirmed by histopathological examination of biopsy samples (n=6) or suspected based on gross examination at surgery (n=1). In six cats, a section of 3.5 to five French gauge red rubber catheter and in one cat a section of 22 G intravenous catheter were used as a choledochal stent. Two cats developed re-obstruction of the biliary tract within a week of the original surgery. One cat had confirmed episodes of ascending cholangitis postoperatively. Two cats had chronic intermittent vomiting in the postoperative period. Two cats died during the perioperative period. Five cats survived to discharge, three of which died seven to 24 months postoperatively and two of which remain alive to date.
Choledochal stenting is an alternative to biliary diversion for management of feline pancreatitis-associated EHBO in select cases. However, there may be greater morbidity with this technique in cats compared with dogs.
报告经胆总管置管支架治疗的胰腺炎相关性肝外胆管梗阻（EHBO）猫的临床病理特征及预后情况。
回顾了因胰腺炎继发EHBO而接受胆总管支架置入术的猫的病历。通过对猫进行复查或与猫主人电话访谈获取预后信息。
所有猫均经活检样本组织病理学检查确诊为胰腺炎（n = 6），或在手术大体检查时疑似胰腺炎（n = 1）。6只猫使用一段3.5至5法式规格的红色橡胶导管作为胆总管支架，1只猫使用一段22G静脉导管作为胆总管支架。2只猫在初次手术后一周内出现胆道再次梗阻。1只猫术后确诊发生上行性胆管炎。2只猫在术后出现慢性间歇性呕吐。2只猫在围手术期死亡。5只猫存活至出院，其中3只在术后7至24个月死亡，2只至今仍存活。
在某些病例中，胆总管支架置入术是治疗猫胰腺炎相关性EHBO的一种替代胆管改道术的方法。然而，与犬相比，该技术在猫中可能会导致更高的发病率。
