In endoscopic biliary drainage (EBD) for various benign and malignant biliary disorders, the appropriate timing to replace or change a plastic stent (PS) with a self-expandable metallic stent (SEMS) remains unclear. This study aimed to define the best period to replace or change a PS with a SEMS. Between January 1, 2012, and December 31, 2018, 1,887 consecutive EBD procedures, including 170 SEMS placements, were retrospectively identified. Read More

Use of endoscopic ultrasound-guided biliary drainage (EUS-BD) has recently increased. In EUS-BD, after puncturing the bile duct, dilation is performed and the stent is deployed. Due to adverse events (AEs) such as unexpected displacement of the guidewire, simplified procedures are required. Read More

Significant morbidity and mortality have been associated with liver complications after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Causes and consequences of these hepato-biliary complications are various and might be life-threatening. A high misdiagnosis rate has been reported because of a weak correlation between clinical, laboratory and imaging data. Read More

Background: Endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) is a common technique for biliary drainage. However, EUS-CDS is associated with adverse events such as cystic duct obstruction, stent dislocation, and stent kinking caused by powerful axial force. A novel double-bare, covered self-expandable metal stent (DBSEMS) has recently become available in Japan. Read More

Endoscopic ultrasound (EUS) was originally devised as a novel diagnostic technique to enable endoscopists to stage malignancies and acquire tissue. However, it rapidly advanced toward therapeutic applications and has provided gastroenterologists with the ability to effectively treat and manage advanced diseases in a minimally invasive manner. EUS-guided biliary drainage (EUS-BD) has gained considerable attention as an approach to provide relief in malignant and benign biliary obstruction for patients when endoscopic retrograde cholangiopancreatography (ERCP) fails or is not feasible.

Acute cholecystitis is a rare cause of gastric outlet obstruction (GOO) and may manifest with nonspecific symptoms which may preclude or delay diagnosis. During the latter part of the 20th century, benign disease was responsible for most cases of GOO in adults with peptic ulcer disease accounting for up to 90% of these cases. Although precise estimates on GOO incidence and prevalence are lacking, as many as 2000 surgical operations were reportedly performed annually for GOO in the United States in the 1990s. Read More

Background And Study Aims: Although routine preoperative biliary drainage (PBD) in patients with distal malignant biliary obstruction is generally not recommended, there are still various situations where it may be necessary. The current study aims to compare between the uncovered self-expandable metal stent (uSEMS) and plastic stent (PS), where PBD may be necessary.

Patients And Methods: In this multicenter prospective randomized study, patients with resectable periampullary cancer with cholangitis, deep jaundice, or expected long waiting time for surgery were included. Read More

Most patients who require biliary drainage can be treated by endoscopic retrograde cholangiopancreatography (ERCP)- guided procedures. However, ERCP can be challenging in patients with complications, such as malignant duodenal obstruction, or a surgically-altered anatomy, such as a Rouxen- Y anastomosis, which prevent advancement of the duodenoscope into the ampulla of Vater. Recently, endoscopic ultrasound (EUS)-guided biliary drainage via transhepatic or transduodenal approaches has emerged as an alternative means of biliary drainage. Read More

Background: Pancreatoduodenectomy (PD) for duodenal adenoma (DA) resection may be associated with excessive surgical risk for patients with potentially benign lesions, given the absence of pancreatic duct obstruction. We examined factors associated with final malignant pathology and evaluated the postoperative course of patients with DA versus pancreatic ductal adenocarcinoma (PDAC).

Methods: We retrospectively analyzed patients with DA who underwent PD from 2008 to 2018 and assessed the accuracy rate of preoperative biopsy and factors associated with final malignant pathology. Read More

This video case report presents a patient with an invasive pancreatic mass and a history of Roux-en-Y gastric bypass surgery who underwent single-session endoscopic ultrasound-directed transgastric ERCP for tissue sampling and biliary stenting with subsequent maintenance of the newly established gastrogastrostomy. The demonstrated technique enables spectrum of endoscopic interventions in gastric bypass patients by facilitating a direct endoscopic passage through the reconnected stomach. Importantly, the method carries a risk of weight regain by essentially reversing the bypass. Read More

Acute choledocholithiasis results when stones form in the gallbladder and then pass into the common bile duct, where they may become lodged and cause obstruction. To our knowledge, very few cases are reported in which multiple imaging techniques had failed to detect the presence of gallstones, as per current literature review. We report a case of a 73-year-old woman with nausea, vomiting, and jaundice who was found to have choledocholithiasis with negative imaging on abdominal ultrasound (US), CT, and magnetic resonance cholangiopancreatography (MRCP).

Most patients with cholangiocarcinoma (CCA) develop extrahepatic malignant biliary obstructions, which require palliative drainage to normalize bilirubin levels and to improve the patients' overall survival. Here, we report that the infusion of methotrexate-containing plasma-membrane microvesicles derived from apoptotic human tumour cells into the bile-duct lumen of patients with extrahepatic CCA mobilized and activated neutrophils and relieved biliary obstruction in 25% of the patients. Neutrophil recruitment by the microvesicles was associated with an increase in uridine diphosphate glucose and complement C5, and led to the degradation of the stromal barrier of CCA. Read More
