Distal cholangiocarcinoma: case report and brief review of the literature.

Adenocarcinomas of the distal bile duct are traditionally classified as either pancreatobiliary or intestinal type, with pancreatic adenocarcinoma and cholangiocarcinoma included within the former classification. Cholangiocarcinoma is a rare and deadly malignancy that occurs within three clinically defined regions: intrahepatic, perihilar, and in the distal bile duct. We present a 68-year-old male with a past medical history of human immunodeficiency virus, hepatitis B, hypertension, and hyperlipidemia who presented to the emergency department with a 3-week history of diarrhea, diffuse abdominal pain, malaise, and nausea.

"Innocent as a LAMS": Does Spontaneous Fistula Closure (Secondary Intention), After EUS-Directed Transgastric ERCP (EDGE) via 20-mm Lumen-Apposing Metal Stent, Confer an Increased Risk of Persistent Fistula and Unintentional Weight Gain?

Background And Aims: Persistent gastrogastric or jejunogastric fistula is theoretically a concerning sequela of EUS-directed transgastric ERCP/EUS (EDGE), as it may functionally reverse the malabsorptive mechanism of Roux-en-Y gastric bypass (RYGB). Prior EDGE studies, using predominantly 15-mm (diameter) lumen-apposing metal stents (LAMS) and fistula closure by primary intent, collectively report 9% persistent fistula rate, without a clear weight gain association. Our study determines the incidence of persistent fistula, and its association with unintentional weight gain, among recipients of EDGE via 20-mm LAMS followed by spontaneous fistula closure (secondary intent).

Endoscopic ultrasound-directed transgastric ERCP (EDGE): a retrospective multicenter study.

Background: Endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography (ERCP; EDGE) is an alternative to enteroscopy- and laparoscopy-assisted ERCP in patients with Roux-en-Y gastric bypass anatomy. Although short-term results are promising, the long-term outcomes are not known. The aims of this study were: (1) to determine the rates of long-term adverse events after EDGE, with a focus on rates of persistent gastrogastric or jejunogastric fistula; (2) to identify predictors of persistent fistula; (3) to assess the outcomes of endoscopic closure when persistent fistula is encountered.

Shortened-Interval Dual-Session EDGE Reduces the Risk of LAMS Dislodgement While Facilitating Timely ERCP.

Background And Aims: EUS-directed transgastric ERCP (EDGE) is an endoscopic modality for treating pancreaticobiliary disorders after Roux-en-Y gastric bypass. EDGE consists of EUS-directed gastrogastrostomy/jejunogastrostomy creation (EUS-GG; step 1), followed by transgastric ERCP (step 2). The two steps can be performed in the same or separate endoscopic session(s).

Endoscopic endgame for obstructive pancreatopathy: outcomes of anterograde EUS-guided pancreatic duct drainage. A dual-center study.

Background And Aims: Anterograde endoscopic ultrasound-guided pancreatic duct drainage (EUS-PDD) refers to transmural drainage of the main pancreatic duct via an endoprosthesis passed anterograde through the gastric (or intestinal) wall. Anterograde EUS-PDD is a rescue procedure for recalcitrant cases of benign obstructive pancreatopathy.

Methods: We conducted a dual-center retrospective chart review of 28 patients (mean age, 59 years; 50% female) who underwent attempted anterograde EUS-PDD between April 2016 and September 2019 for chronic pancreatitis (CP) (93%) or pancreaticojejunostomy stenosis (PJS) after Whipple resection (7%).

Anterograde Endoscopic Ultrasound-Guided Pancreatic Duct Drainage: A Technical Review.

The advancement of pancreatic endotherapy has increased the availability of minimally invasive endoscopic pancreatic ductal drainage techniques. In this regard, familiarity with endoscopic ultrasound-guided pancreatic duct drainage (EUS-PDD) is critical for treatment of obstructed pancreatic ductal systems, especially in nonsurgical candidates and in patients desiring a minimally invasive approach. Two distinct forms of EUS-PDD exist, viz.
