Antral mucosal perfusion is not increased in GAVE.

Objectives: Although a common cause of intestinal blood loss, the pathophysiology of gastric antral vascular ectasia (GAVE) is not well understood. We aimed to evaluate gastric antral and body mucosal flow in GAVE patients compared to a control population using laser Doppler flowmetry.

Methods: 27 patients with GAVE and 11 control patients without GAVE were evaluated using an endoscopic LDF probe.

Clinical Characterization of Gastric Antral Vascular Ectasia: A Potential Manifestation of the Metabolic Syndrome.

Background And Objectives: Gastric antral vascular ectasia is a relatively common endoscopic finding. Past studies have shown an association of gastric antral vascular ectasia with cirrhosis and autoimmune disorders. We aimed to re-examine these associations and to investigate a possible association of gastric antral vascular ectasia with features of the metabolic syndrome.

Accuracy of endoscopic ultrasound in the diagnosis of T2N0 esophageal cancer.

Background: Accurate staging of esophageal carcinoma (EC) is important since it directs further management. Endoscopic ultrasound (EUS) is the best tool available in the locoregional staging of EC; however, differentiating depth of tumor invasion (T) and nodal involvement (N) can be challenging. Accurate staging is particularly important to differentiate T1-2 N0 cancers, which can proceed directly to surgical resection versus TXN1 or T3N0/1 cancers, which benefit from induction chemoradiation prior to surgery.

Coil migration after transarterial coil embolization of a splenic artery pseudoaneurysm.

A 48-year-old man with a history of splenic artery pseudoaneurysm requiring transarterial embolization 3 months earlier presented to the emergency department with abdominal pain and fever. Computed tomography showed evidence of embolization coil fragments within the gastrointestinal tract. Upper endoscopy showed a large gastric ulcer with numerous embolization coils extruding into the gastric lumen.

Percutaneous gastrostomy tube placement to perform transgastrostomy endoscopic retrograde cholangiopancreaticography in patients with Roux-en-Y anatomy.

Background: Roux-en-Y gastric bypass (RYGB) surgery is one of the most commonly performed bariatric surgeries in the United States. Patients with prior RYGB are not amenable to conventional endoscopic retrograde cholangiopancreaticography (ERCP). Surgical gastrostomy (SG) tube placement enables transgastrostomy ERCP (TG-ERCP).

Endoscopic palliation for pancreatic cancer.

Pancreatic cancer is devastating due to its poor prognosis. Patients require a multidisciplinary approach to guide available options, mostly palliative because of advanced disease at presentation. Palliation including relief of biliary obstruction, gastric outlet obstruction, and cancer-related pain has become the focus in patients whose cancer is determined to be unresectable.
