BACKGROUND Cholangioscopy is a useful tool for the study and treatment of biliary pathology. Ultrathin upper endoscopes allow direct peroral cholangioscopy (DPC) but have some drawbacks. OBJECTIVE The aim of the study was to evaluate the success rate of DPC with an ultrathin endoscope using a balloon catheter to reach the biliary confluence. MATERIAL AND METHODS Prospective observational st...
The first-line endoscopic strategy for the treatment of benign biliary stricture (BBS) consists of balloon dilation combined with the placement of multiple plastic stents, which has a success rate of more than 80%. Nevertheless, stricture may recur in 10% to 30% of cases after initial resolution [1,2]. Cholangioscopy is a useful adjunct to endoscopic retrograde cholangiopancreatography (ERCP) f...
Radiofrequency ablation (RFA) has been shown to be an efficacious therapy that improves survival in patients with malignant biliary strictures [1]. Direct cholangioscopy can be useful in confirming a successful response to therapy. We present the case of a patient who underwent RFA of a distal malignant biliary stricture, with cholangioscopic images obtained before and after the procedure confi...
Background and study aims Endoscopic removal of biliary stones has high success rates, ranging between 85 % to 95 %. Nevertheless, some stones may be challenging and different endoscopic methods have evolved. Papillary large balloon dilation after sphincterotomy is a widely used technique with success rates ranging from 68 to 90 % for stones larger than 15 mm. Cholangioscopy allows performing ...
Objective: To determine the role of and indications for peroral cholangioscopy using SpyGlass system in differential diagnosis biliary tract lesions case strictures, based on literature data analysis our own experience. Materials methods: Peroral is mainly used lesions. During cholangioscopy, we carefully consider gross signs damage to bile duct mucosa: abnormal capillary vascular pattern, gran...
Cholangioscopy not only enables the direct visualization of the biliary tree, but also allows for forceps biopsy to diagnosis early cholangiocarcinoma. Recently, some reports have suggested the clinical usefulness of direct peroral cholangioscopy (POC) using an ultra-slim endoscope with a standard endoscopic unit by a single operator. Enhanced endoscopy, such as narrow band imaging (NBI), can b...
Direct examination of the biliary tree with endoscopes has been a challenge since endoscopists began performing endoscopic retrograde cholangiopancreatography (ERCP) in the late 1960s. Previously, surgeons had used rigid instruments intraoperatively, which made examination difficult. The first direct cholangioscopy performed by an endoscopist was likely unintentionally done in a patient with po...
