S16 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 for cases which require immunohistochemistry, for example, neuroendocrine tumor, lymphoma, and mediastinal tumors. (3) EUS is the most important tool for pancreatic cystic lesions. (4) EUS is an important tool for diagnosis of CBD and gallbladder masses. EUS gives accurate diagnosis in gastric submucosal lesions, infiltrative gas...

A 44-year-old woman was referred for endoscopic ultrasound (EUS) evaluation of a gastric submucosal tumor that was found during a health checkup. At endoscopy, a tuliplike mass with a central lobulated dent was found in the upper body of the stomach (Fig. 1). A biopsy disclosed only dilated blood vessels in edematous stroma. EUS revealed a 29 × 25-mm inhomogeneously hypoechoic protruding mass i...

Bleeding is a complication of gastrointestinal vascular malformation and may be an emergency. Dieulafoy's lesion is rare but the aberrant submucosal artery may cause gastrointestinal bleeding. It is most commonly located in the proximal part of the stomach. Endoscopy is used for diagnosis and treatment. Mass lesions, diffuse lesions and severe bleeding may require surgery. Wedge resection or le...

Mortality from esophageal cancer remains high despite advances in medical therapy. Although the incidence of squamous cell carcinoma of the esophagus remains unchanged, the incidence of the esophageal adenocarcinoma has increased over time. Gastroesophageal reflux disease (GERD and obesity are contributing factors to the development of Barrett's esophagus and subsequent development of adenocarc...

Endoscopic mucosal resection (EMR) is an endoscopic alternative to surgical resection of mucosal and submucosal neoplastic lesions and intramucosal cancers. EMR offers both diagnostic and therapeutic capability. Lesions limited to the mucosa and the superficial layers of the submucosa appear to be the most amenable to endoscopic cure. The techniques for EMR can be broadly divided into two group...

Gastrointestinal stromal tumors (GISTs) account for approximately 2% of gastric cancers and can be challenging to diagnose due to the difficulty sampling tissue from these lesions. Current biopsy methods are inadequate for determining the mitotic index, a major prognostic factor of these tumors. We sought to evaluate the ability of a prototype submucosal biopsy forceps to make a histologic diag...

Preoperative differential diagnosis of gastric submucosal tumors has generally been difficult because they are covered with normal mucosa. However, recent advances in endoscopic ultrasound (EUS)-guided sampling of submucosal gastrointestinal lesions have made it possible to achieve preoperative differential diagnosis of gastric submucosal tumors. A 76-year-old woman was referred to our hospital...

OBJECTIVE Complications are important determining factors for safety of endoscopic submucosal dissection (ESD). ESD of large lesions is associated with increased procedural time. This study investigated whether double-channel gastroscope could be used to reduce procedural time in gastric antrum ESD. METHODS A retrospective cohort study of 46 patients with one gastric antrum lesion resected by...

BACKGROUND Several minimally invasive technologies are available to treat common soft tissue lesions including symptomatic hemorrhoids. The use of energy to deliver heat and coagulate target lesions is commonly practiced. This study compares the histologic effects produced on intestinal tissues by two energy-based systems which employ different approaches of heat delivery. METHODS TWO HEAT DE...
