A model of deformable rings for interpretation of wireless capsule endoscopic videos.

Wireless Capsule Endoscopy (WCE) provides a means to obtain a detailed video of the small intestine. A single session with WCE may produce nearly 8h of video. Its interpretation is tedious task, which requires considerable expertise and is very stressful.

Modified technique of high-resolution ultrasonography of the normal cervical esophagus.

Background And Aim: To study a modified technique of neck ultrasound for the visualization of cervical esophagus using a high-resolution and high frequency linear transducer in normal subjects.

Methods: Consecutive control subjects were patients who underwent abdominal sonography for other diseases and had no past or current history of dysphagia or esophageal disorders. The thyroid gland was used as a transducer window to obtain images.

Successful closure of spontaneous esophageal perforation (Boerhaave's syndrome) by endoscopic clipping.

Endoscopic clips have been used mainly for control of gastrointestinal (GI) bleeding and occasionally for closure of GI perforations. However, closure of spontaneous esophageal perforation (Boerhaave's syndrome) by clipping has not been reported. We described successful non-surgical closure of spontaneous esophageal perforation by endoscopic clipping in a patient with bilateral pyopneumothorax and septicemia.

Early institution of pre-cutting for difficult biliary cannulation: a prospective study comparing conventional vs. a modified technique.

Background: Pre-cutting techniques have been used to gain biliary access at the expense of an increased complication rate. This may be because of the multiple attempts to achieve cannulation by using standard methods before pre-cutting and causing excess edema and papillary trauma. There are limited data on the early use of pre-cutting techniques.

Aggressive endoscopic therapy for pancreatic necrosis and pancreatic abscess: a new safe and effective treatment algorithm (videos).

Background: Pancreatic necrosis and pancreatic abscess are severe complications of acute pancreatitis. Surgery is associated with significant morbidity and mortality in these critically ill patients. Endoscopic therapy has the potential to offer a safer and more effective alternative treatment modality.

Infliximab in the treatment of ulcerative colitis with toxic megacolon.

Toxic megacolon is a gastrointestinal emergency requiring prompt management to avoid fatal outcome. Although a majority of patients respond to conservative treatment, those not responding have been treated with intravenous cyclosporine or emergency surgery. Infliximab has been tried in patients with severe steroid-refractory ulcerative colitis.

Endoscopic diagnosis and management of tropical parasitic infestations.

Biliary parasitosis is one of the common causes of biliary obstruction in developing countries and can often be confused with stone disease. With increased worldwide travel and immigration, these conditions are not limited to the developing countries alone. Ascariasis, hydatid liver disease, clonorchiasis, and fascioliasis are the commonly encountered parasitic infestations of the biliary tract usually presenting with biliary colic or cholangitis.

Endoscopic treatment of biliary leakage with n-butyl-2 cyanoacrylate.

Background: Biliary leakage is a problematic complication of hepatobiliary surgery. A novel alternative method is described that can obviate the need for reoperation for refractory biliary fistula.

Methods: Nine patients with large biliary leaks unresponsive to endoscopic drainage underwent N-butyl-2-cyanoacrylate glue occlusion at ERCP.
