Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract; however, the occurrence of a GIST in the duodenum is rare. Our case demonstrates the importance of considering GIST in the evaluation of refractory duodenal ulcers, as well as the utilization of endoscopic ultrasound in the evaluation of these lesions.

Introduction: Determination of type and location of trapped objects and endoscopic observations among children with foreign-body ingestion. Materials and Methods: We evaluated 105 endoscopic records of patients presenting with foreign-body ingestion from 2001–2011. Results: Button batteries were the most common objects removed (41%). The lower segment of the esophagus was the most common trappi...

600.646 Compute Integrated Surgery II Group 4 Project Proposal Stated Topic: Surgical skill evaluation in endoscopic sinus surgery Goal: Develop a mathematical model on surgical skill evaluation to identify and model the motion of critical movements to determine when these movements can lead to surgical complications. Team members: Vishwa Parekh Mentors: Dr. Gregory Hager, Daniel Mirota, Narges...

OBJECTIVE To review retrospective data of 60 patients who underwent endoscopic septoplasty over a period of two years. METHODS The medical records of 60 patients who underwent endoscopic septoplasty during the period December 2008 and November 2009 at the King Hussein Medical Center (Amman, Jordan) were reviewed for surgical indications, intraoperative technique, findings, and postoperative c...

Dacrycystorhinostomy (DCR) is a procedure performed to drain the lacrimal sac in cases of nasolacrimal duct obstruction or in chronic dacryocystitis. It can be performed externally or endoscopically. This is a prospective, nonrandomized study involving twenty-two consecutive patients (16 Females and 6 Males; mean age 45.54 y; range 18-74 y) who presented to the DCR clinic with epiphora secondar...

Post-endoscopic sphincterotomy bleeding is a common complication of biliary sphincterotomy, and the incidence varies from 1% to 48%. It can be challenging to localize the bleeder or to administer various interventions through a side-viewing endoscope. This study aimed to evaluate the risk factors of post-endoscopic sphincterotomy bleeding and the outcome of endoscopic intervention therapies. We...

Aim of this prospective preliminary study was to assess effectiveness and reliability of autofluorescence endoscopy in the diagnosis of laryngeal lesions, in particular, evaluating whether it could represent an improvement in comparison to standard endoscopy alone. A total of 81 laryngeal biopsy specimens, taken from 46 consecutive patients who underwent intra-operative endoscopic assessment in...

BACKGROUND AND AIMS Although several noninvasive and easily accessible biomarkers for inflammatory bowel disease [IBD] are available, their sensitivity and specificity are not adequate to be used as single markers and do not overrule the need for endoscopic evaluation. We previously reported that serum leucine-rich alpha-2 glycoprotein [LRG] was a novel biomarker for rheumatoid arthritis and IB...

OBJECTIVES/HYPOTHESIS Endoscopic management of bilateral vocal fold paralysis (BVFP) includes cordotomy and arytenoidectomy, and has become a well-accepted alternative to tracheostomy. However, the costs and quality-of-life benefits of endoscopic management have not been examined with formal economic analysis. This study undertakes a cost-effectiveness analysis of tracheostomy versus endoscopic...
