Use of Endoscopic Ultrasound in a Diagnostic Dilemma: Metastatic Breast Cancer to the Stomach.

A 55-year-old woman presented with persistent nausea, vomiting, and weight loss previously attributed to Ménétrier's disease. On further workup, she was found to have metastatic lobular breast carcinoma causing gastric outlet obstruction, diagnosed by endoscopic ultrasound with fine needle aspiration after previous gastric mucosal biopsies were unremarkable. In most reported cases of gastric metastasis from breast cancer, a diagnosis was established by mucosal biopsy.

Castleman's Disease and Posttransplant Lymphoproliferative Disorder after Liver Transplant: 3-Year Follow-Up.

A 59-year-old male with a history of hepatitis C cirrhosis and history of hepatitis B exposure presented 8 months after orthotopic liver transplant (LT) with fever, fatigue, myalgia, night sweats, nonproductive cough, and shortness of breath. Bone marrow biopsy for pancytopenia was positive for Epstein-Barr virus (EBV) DNA. Lymph node biopsy for lymphadenopathy on imaging showed human herpes virus 8 (HHV8) associated Castleman's disease.

Gastrointestinal Bleeding With Left Ventricular Assist Devices (LVAD): Locating the Leak and Identifying Outcomes.

Background And Goals: Gastrointestinal bleeding (GIB) is a significant complication following left ventricular assist device (LVAD) implantation. We evaluated the incidence, predictors, endoscopic findings, and outcomes of GIB in LVAD recipients.

Study: Retrospective review of 205 adult patients undergoing HeartMate II LVAD implantation from January 2012 to June 2016.

Needle-Knife Fistulotomy for the Rescue: An Unusual Cause of Iatrogenic Extrahepatic Biliary Obstruction.

A 71-year-old male presented to our institution with cholestatic hepatitis after having recently undergone upper endoscopy for treatment of gastrointestinal bleeding. Further investigation with endoscopic retrograde cholangiopancreatography revealed a hemostatic clip on the ampulla of Vater. After initial attempts at cannulation of the common bile duct were unsuccessful, biliary decompression was achieved by use of needle-knife fistulotomy.
