Abstract
Otoimmün kolanjiyopati veya immünglobulin G4 ilişkili sklerozan kolanjit immün sistem ilişkili bir kolanjit tipidir. Otoimmün pankreatit sıklıkla bu duruma eşlik eder; bununla beraber hastaların çok az bir yüzdesinde otoimmün kolanjiyopati tek başına da görülebilir. 69 yaşında kadın hasta kliniğimize halsizlik, kaşıntı ve sarılıkla başvurdu. Endoskopik retrograd kolanjiopankreatografi de intrahepatik safra yollarında çok sayıda darlık ve dilatasyonlarla beraber ana koledok distalde darlığa rastlandı. Sklerozan kolanjitin diğer nedenlerini ekarte edebilmek için hastadan immünglobulin G4 çalışıldı ve sonuç 1.200 mg/dl olarak geldi. Bu sonuçla otoimmün kolanjiyopati tanısı kondu. Otoimmün kolanjiyopati intrahepatik ve/veya extrahepatik safra yollarında darlık olan hastalarda ayırıcı tanıda mutlaka akılda tutulmalıdır. Şüphe edilen hastalarda immünglobulin G4 tarama amaçlı kullanılabilir. Otoimmün kolanjiyopatinin tanı ve tedavisi hastaları ilerleyen zamanda siroz veya gereksiz cerrahiden koruyacaktır.

Abstract
Autoimmune cholangiopathy or IgG4-related sclerosan cholangitis is an immune- mediated type of cholangitis. Autoimmune pancreatitis is frequently associated with this condition. However, in a minority of patients, autoimmune cholangiopathy exist alone. A 69- year-old female patient was admitted to our hospital with fatigue, pruritus, and jaundice. There were multiple strictures and dilations in the intrahepatic biliary tree with stricture in the distal part of the common bile duct. To exclude other causes of sclerosan cholangitis, IgG4 was studied. The IgG4 titer was 1200 mg/dl; therefore, the diagnosis was autoimmune cholangiopathy. Autoimmune cholangiopathy must be investigated in patients with biliary strictures in either the intrahepatic or extrahepatic bile ducts. IgG4 can be used to screen for autoimmune cholangitis. Diagnosis and treatment of this condition prevents patients from cirrhosis and unnecessary surgery.
