Biliary cast syndrome (BCS) is an unusual complication of liver transplantation (LT). The pathophysiology is not known, and it is thought to develop because of mucosal damage in the bile duct related to obstruction, ischemia, or bacterial infection. It occurs in 2.

Biliary tract diseases are the most common complications following liver transplantation (LT) and usually include biliary leaks, strictures, and stone disease. Compared to deceased donor liver transplantation in adults, living donor liver transplantation is plagued by a higher rate of biliary complications. These may be promoted by multiple risk factors related to recipient, graft, operative factors and post-operative course.

Pneumatosis cystoides intestinalis features the presence of subserum or submucous cysts with gas in the intestinal wall. Its prevalence is 0.03%, although it has increased in the past decades due to a greater use of colonoscopy in everyday medical practice.

Pseudocysts and biliary obstructions will affect approximately one third of patients with chronic pancreatitis (CP). For CP-related, uncomplicated, pancreatic pseudocysts (PPC), endoscopy is the first-choice therapeutic option. Recent advances have focused on endosonography-guided PPC transmural drainage, which tends to replace the conventional, duodenoscope-based coma immediately approach.

Background: The use of propofol during colonoscopy has become more widespread. To increase availability while maintaining quality and decreasing costs, European Guidelines have been issued for non-anesthesiologist administration of propofol (NAAP). We aimed to assess the current use of propofol during screening colonoscopy.

Background: Prophylactic pancreatic stenting is widely used by expert biliary endoscopists to prevent post-ERCP pancreatitis (PEP); nonsteroidal anti-inflammatory drugs (NSAIDs) are thought to prevent PEP.

Objective: To assess the use of pancreatic stenting and NSAIDs for PEP prophylaxis among endoscopists and its determinants.

Design: A survey was distributed to 467 endoscopists attending a course on therapeutic digestive endoscopy.

Background: Although data about the incidence and management of biliary complications after deceased-donor liver transplantation (DDLT) are well defined, those pertaining to adult living-donor liver transplantation (LDLT) are conflicting.

Methods: We retrospectively compared endoscopic retrograde cholangio-pancreatography (ERCP) findings in 30 LDLT vs. 357 DDLT consecutive adult recipients with duct-to-duct biliary reconstruction.

Objectives: Brushing, the standard sampling method at endoscopic retrograde cholangiography (ERC), lacks sensitivity for cancer detection. We assessed a novel sampling method using a grasping basket.

Methods: Fifty-six patients with a suspected malignant biliary stricture were randomized to biliary sampling at ERC using a basket (basket group, N = 30) or a brush (brush group, N = 26), followed by the alternate device.
