摘要To the Editor:Acute cholangitis,also known as ascending cholangitis,is a po-tentially life-threatening condition resulting from the infection and obstruction of the biliary tract[1].Choledocholithiasis,which in-volves stones in the common bile duct,is the most frequent cause of such infections,leading to partial or complete blockage of the biliary system[2].During acute episodes,patients may present with abdominal pain,high fever,and jaundice,known as Charcot’s triad,and in severe cases,patients may also exhibit signs of shock and depression[3].An episode of cholangitis can be fatal,and if the underlying obstruction is not addressed,the condition may recur,potentially leading to hepatic abscesses or biliary cirrhosis.Other etiologies of cholangitis include benign biliary strictures,bil-iary malignancies,congenital factors,postoperative complications,inflammatory conditions,and rare causes such as pancreatitis,par-asitic invasion of the biliary tract,external compression,thrombo-sis,and iatrogenic factors.Acute cholecystitis due to the migration of Hem-o-lok clips postoperation is rare.Herein we reported a case of acute cholangitis caused by the migration of surgical Hem-o-lok clips into the bile duct six years after laparoscopic left hemihepa-tectomy.
