Successful Endoscopic Closure of Pyeloduodenal Fistula Using an Over-the-Scope Clip.

A 62-year-old woman underwent a series of urologic procedures for nephrolithiasis and was diagnosed with a pyeloduodenal fistula (PDF) on computed tomography urography. After the placement of a metallic ureteral stent and nephrostomy tube, an esophagogastroduodenoscopy was performed to evaluate for PDF resolution. Two areas of mucosal defects within the anterior duodenal sweep were closed using the over-the-scope clip system and hemostasis clips.

Accuracy of Referring Provider and Endoscopist Impressions of Colonoscopy Indication.

Referring provider and endoscopist impressions of colonoscopy indication are used for clinical care, reimbursement, and quality reporting decisions; however, the accuracy of these impressions is unknown. This study assessed the sensitivity, specificity, positive and negative predictive value, and overall accuracy of methods to classify colonoscopy indication, including referring provider impression, endoscopist impression, and administrative algorithm compared with gold standard chart review. We randomly sampled 400 patients undergoing a colonoscopy at a Veterans Affairs health system between January 2010 and December 2010.

New anticoagulants and antiplatelet agents: a primer for the clinical gastroenterologist.

The discovery of the first oral anticoagulant, warfarin, was a milestone in anticoagulation. Warfarin's well-known limitations, however, have led to the recent development of more effective anticoagulants. The rapidly growing list of these drugs, however, presents a challenge to endoscopists who must treat patients on these sundry medications.
