PURPOSE Gastric mucosal neoplastic lesions should have characteristic endoscopic features for successful endoscopic submucosal dissection. MATERIALS AND METHODS Out of the 1,010 endoscopic submucosal dissection, we enrolled 62 patients that had the procedure cancelled. Retrospectively, whether the reasons for cancelling the endoscopic submucosal dissection were consistent with the indications...

transradial coronary angiography has been known as an alternative to the transfemoral approach with fewer serious complications. radial artery pseudoaneurysms present as a rare complication of transradial catheterization. although some methods have been applied for the obliteration of pseudoaneurysms, the use of radial bands such as the tr band ® (terumo medical corporation, somerset, nj) is a ...

BACKGROUND Coronary artery bypass grafting using the radial artery has, since the 1990s, gone through a revival. Observational studies have indicated better long-term patency when using radial arteries. Therefore, radial artery might be preferred especially in younger patients where long time patency is important. During the last 10 years different endoscopic techniques to harvest the radial ar...

A review and update on tridimensional ultrasonography covering all its aspects, ultrasonography and 3D endoscopic ultrasonography, its technical details and current indications, such as volume calculation, vascular architecture assessment, and role in interventionist ultrasounds. Images included are from the author's own experience.

Posterior interosseous nerve palsy caused by a ganglion is not common and most previous patients were treated with excisional surgery. We treated a case conservatively with needle aspiration using ultrasonography, after a nerve conduction study. A 77-year-old man presented with impaired active finger extension of the left metacarpophalangeal joints. The nerve conduction study revealed conductio...

Endoscopic ultrasonography is usually used in the diagnosis of subepithelial tumors but requires special equipment and expertise, which can be obstacles some clinics. Transabdominal an easily available diagnostic tool for diagnosing gastric tumors. Hydroultrasonography depict all five layers stomach wall. On ultrasonography, lipoma recognized as a well demarcated hyperechoic mass mainly located...

BACKGROUND/AIMS The optimal training mode for linear array endoscopic ultrasonography (EUS) has not been established. Prior radial-scanning EUS training seems to improve subsequent linear array EUS learning. The objective of this randomized controlled trial was to evaluate its value in linear array EUS training. METHODS In total, 18 freshman trainees conducted hands-on EUS operations on a liv...

OBJECTIVE To study the efficacy and safety of endoscopic ultrasonography-guided fine-needle aspiration in the management of mediastinal diseases in Hong Kong. DESIGN Retrospective review of prospectively collected data. SETTING University teaching hospital, Hong Kong. PATIENTS A total of 125 consecutive patients with various mediastinal and pulmonary lesions that underwent trans-oesophage...

The pathogenesis of idiopathic chronic pancreatitis remains poorly understood despite the high expectations for ascribing the pancreatic damage in affected patients to genetic defects. Mutations in the cationic trypsinogen gene, pancreatic secretory trypsin inhibitor, and the cystic fibrosis conductance regulator gene do not account for the chronic pancreatitis noted in most patients with idiop...

Endoscopic ultrasonography (EUS), introduced into gastroenterological diagnostics more than 20 years ago, has undergone extensive evaluation of its diagnostic capability, probably to a larger extent than most other endoscopic and other imaging techniques in gastroenterology. Almost necessarily, as to be expected with an imaging method being assessed with continuing interest for two decades, ini...
