Background: Little is known about the long-term results of endoscopic papillary balloon dilation (EPBD) for bile duct stones. Methods: Between 1995 and 2000, 204 patients with bile duct stones successfully underwent EPBD and stone removal. Complete stone clearance was confirmed using balloon cholangiography and intraductal ultrasonography (IDUS). Long-term outcomes of EPBD were investigated retrospectively in the year 2007, and risk factors for stone recurrence were multivariately analyzed. Results: Long-term information was available in 182 cases (89.2%), with a mean overall follow-up duration of 9.3 years. Late biliary complications occurred in 22 patients (12.1%), stone recurrence in 13 (7.1%), cholangitis in 10 (5.5%), cholecystitis in four, and gallstone pancreatitis in one. In 11 of 13 patients (84.6%), stone recurrence developed within 3 years after EPBD. All recurrent stones were bilirubinate. Multivariate analysis identified three risk factors for stone recurrence: dilated bile duct (>15 mm), previous cholecystectomy, and no confirmation of clean duct using IDUS. Conclusion: Approximately 7% of patients develop stone recurrence after EPBD; however, retreatment with endoscopic retrograde cholangiopancreatography is effective. Careful follow up is necessary in patients with dilated bile duct or previous cholecystectomy. IDUS is useful for reducing stone recurrence after EPBD. [ABSTRACT FROM AUTHOR]

When performing endoscopic retrograde cholangiopancreatography (ERCP), the smooth introduction of the duodenoscope into the papilla of Vater, an appropriate view of the papilla of Vater, and deep cannulation of the bile duct are essential. The operator must know the difference between the side-viewing endoscope and the forward-viewing endoscope. The rotation of the body and the left arm of the operator, switching with the left wrist, and dialing of the endoscope are essential for appropriately viewing the papilla of Vater. When training operators to do ERCP, a model is useful for helping them understand basic handling. The approach to deep cannulation of the bile duct should be selected based on the type of papilla (slit type, onion type, tongue protrusion type, flat type, and tumor type). Cannulation is more difficult in patients with the tongue protrusion-type of papilla than with a slit type, onion type, or tumor type. According to previous reports, therapeutic ERCP requires the ability to cannulate the common bile duct deeply 80% of the time; 180 to 200 supervised ERCP are necessary to achieve this success rate.

The article presents information on the case of a 78-year-old man who was presented to hospital with epigastric pain. It has been concluded that gadolinium is a reasonable alternative to iodine-based endoscopic retrograde cholangiopancreatography (ERCP) contrast in patients with severe iodine allergy.

The article presents the case study of a 44-year-old man who underwent a double-balloon endoscopy (DBE) for hepatolithiasis with stones associated with reflux of intestinal contents to the bile duct due to Roux-en-Y hepaticojejunostomy. It says that at the age of 33-year old, he underwent choledochal cyst excision and hepatolithiasis with multiple stones was detected by abdominal computed tomography. It adds that the cholangioscopy demonstrated no residual stones and tumors.
