There are some basic IR techniques everybody needs to know before starting to treat biliary diseases. Τhese are Percutaneous Transhepatic Cholangiography (PTC) and Percutaneous Transhepatic Biliary Drainage (PTBD). These basic procedures are essential first for opacification and then for getting access into the biliary tree. After accessing the biliary system, decisions must be made about the need for further interventional procedures. Presence of benign or malignant strictures, stones or other kind of disease are leading us to the necessary actions, such as dilatation, stenting or lithotripsy. Dilatation of stenosed parts of the biliary system is performed after negotiation of the stricture or occlusion with help of high-pressure angioplasty balloons of variant sizes. Balloons of 8-14 mm width can be used alone or two parallel to each other. Stenting is rarely needed in benign biliary disease and usually in cases where multiple dilatations are not responding. Percutaneous lithotripsy with or without cholangioscopic assistance is a wide-used technique for clearance of biliary stones or fragments. Extraction balloons or baskets and special lithotripsy devices are commonly used for impacted or large calculi.
