Duodenal angiolipoma is a rare adipocytic tumor, with non-specific symptoms precluding an early diagnosis. We present a case of a 67-year-old female admitted due to upper gastrointestinal bleeding. The upper endoscopy and endoscopic ultrasound evaluation showed a subepithelial lesion in the third portion of the duodenum.

A 36-year-old male was diagnosed with a metastasized colon adenocarcinoma causing obstructive jaundice. Magnetic resonance cholangiography showed a dominant lesion causing hilar stenosis. The patient was submitted to endoscopic retrograde cholangiopancreatography (ERCP), nevertheless it was just possible to place a single uncovered self-expandable metallic stent (SEMS) in the right lobe.

Gastric ectopic pancreas (EP) is an uncommon congenital anomaly in which pancreatic tissue with no anatomic connection to the main pancreas is found in the stomach. Gastric EP is often discovered incidentally when a nonspecific submucosal tumor is found in endoscopic studies or other imaging examinations. Tissue characterization by biopsy or fine-needle aspiration is required as endoscopic findings alone cannot exclude malignancy.

Introduction: Anastomotic leak (AL) is a dangerous complication in the early postoperative period after total gastrectomy or esophagectomy being associated with high mortality. Self-expandable metal stents (SEMS) play a significant role in AL management. Only one case report described the use of Mega-Stent in AL setting.

Introduction: Dieulafoy's lesion (DL) is a rare but important cause of acute, severe, life-threatening, and recurrent upper gastrointestinal bleeding (UGIB). It is frequently difficult to diagnose DL with upper GI endoscopy (UGIE), and endoscopic ultrasonography (EUS) may be valuable. There are only 2 reported bleeding cases caused by two synchronous DL but no reported cases of two metachronous DL.

 Outbreak of COVID-19 began in Wuhan in December 2019 and has rapidly spread from China to the rest of the world. Although it is primarily transmitted by contact and droplets, aerosol-generating procedures also seem to carry the possibility of airborne viral transmission. As such, upper gastrointestinal endoscopy can be considered a risky procedure, with several position statements recommending the adoption of safe practices in endoscopic procedures.

Thrombosis and cancer have a very well-known association. Pancreatic cancer has the highest risk for thrombotic events amongst gastrointestinal cancers and is a leading direct cause of death in cancer patients. We assessed the role of endoscopic ultrasound (EUS) in identifying distant thrombotic events in pancreatic cancer patients.
