경피경간 담낭배액술 후 Indigocarmine을 이용한 성공적 담도 삽관 4예

Abstract

Even though percutaneous transhepatic gallbladder drainage (PTGBD) is performed prior to ERCP or following ERCP because of the patients' medical condition or failed bile duct cannulation, there are no definite endoscopic landmarks that are useful for successful bile duct cannulation in some cases. We report here on 4 patients in whom selective bile duct cannulation, as guided by the endoscopic landmarks, was successful following indigocarmine injection via PTGBD.
