Watch a video of this article. Gallbladder (GB) lesions can be diagnosed using several imaging modalities; however, their definitive diagnosis remains challenging. Bile cytology demonstrates unsatisfactory accuracy for GB lesions.1, 2 To improve diagnostic ability, targeted biopsy under direct vision is desirable. Conversely, with the advancement cholangioscopy, has become possible, and bile du...
The traditional mother-daughter system employs a duodenoscope that allows a baby cholangioscope (Fig. 1) to pass through its large instrument channel into the bile duct. This usually requires a sphincterotomy or sphincteroplasty to allow biliary access with the cholangioscope. Two endoscopists are typically required for this procedure, which is limited by the extreme fragility of the cholangios...
Since 1970s the evaluation and treatment of bile duct lesions have been accomplished mostly by endoscopic retrograde cholangiopancreatography (ERCP). However, neither ERCP nor other imaging procedures (e.g., endoscopic ultrasound) allow for safe diagnosis of these lesions. Since the emergence of the fi beroptic SpyGlass Direct Visualization System (SDVS) (Boston Scientifi c, Natick, Massachuset...
The American Society for Gastrointestinal Endoscopy (ASGE) Technology Committee provides reviews of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evidence-based methods are used, with a MEDLINE literature search to identify pertinent clinical studies on the topic and a MAUDE (U.S. Food and Drug Administration Center for Devices and Radio...
The diagnostic and therapeutic effectiveness of combined double-balloon endoscopy with a short endoscope and peroral direct cholangioscopy with an ultraslim endoscope in patients who have altered gastrointestinal anatomy has been demonstrated [1–5]. We describe successful biliary drainage with a short double-balloon endoscope and peroral direct cholangioscopy in a patient who had cholangitis af...
