Possibilities of cholangioscopy in the diagnosis of primary sclerosing cholangitis

Abstract

Diagnosis of the genesis of bile duct strictures is a complex task facing clinicians. The use of cholangioscopy, in particular, the SpyGlass system, is becoming increasingly relevant among oncological patients in case of unsuccessful attempts at previous morphological verification. The presented clinical case demonstrates the capabilities of cholangioscopy as a method of direct visualization of the duct system with the ability to perform a biopsy under vision control in the verification of such a pathology as primary sclerosing cholangitis. Primary sclerosing cholangitis is a rare disease of the biliary tract that requires a systematic approach to diagnosis. The primary task is to identify the etiology of strictures and early diagnosis of cholangiocarcinoma.
