Eosinophilic esophagitis (EoE) is defined by infiltration of eosinophils in the esophageal mucosa (>20 eosinophils/hpf). The epidemiology and seasonal variation have not been well studied in children and adolescents. Review of all esophageal biopsies performed from January 2001 to December 2006 on patients younger than 21 year of age, focusing on(More)
BACKGROUND Endoscopic ultrasound (EUS)--guided fine-needle aspiration (FNA) is frequently performed for diagnostic evaluation of lesions in or near the gastrointestinal (GI) tract. Little data exist concerning possible infectious complications associated with EUS-guided FNA. This prospective evaluation was undertaken to determine the frequency of bacteremia(More)
Schwannomas are generally slow growing asymptomatic neoplasms that rarely occur in the GI tract. However, if found, the most common site is the stomach. Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, and 60-70% of them occur in the stomach. Owing to their typical presentation as submucosal(More)
BACKGROUND Accessory spleen is a common congenital anomaly. There are currently no endoscopic ultrasound (EUS) criteria for the diagnosis or differentiation of this benign splenic anomaly from pathologic disorders including neoplasms. The purpose of this study was to characterize EUS features and develop criteria for the diagnosis of accessory spleen. (More)
The esophageal self-expanding metal stent has gained widespread acceptance for the management of tracheoesophageal fistulas and the palliative management of malignant esophageal strictures. The complications associated with its use can be classified as either immediate or delayed. The most frequent delayed complications include tumor ingrowth, stent(More)
This study aimed to prove that the urinary trypsinogen-2 dip stick test can be used for early diagnosis of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP). For this prospective, blinded, pilot study, urine samples were collected before ERCP, 1 h after ERCP, and 4 h after ERCP. The urine dipstick test was used to detect trypsinogen-2(More)
BACKGROUND Esophagogastroduodenoscopy (EGD) is a rare cause of cerebral air embolism (CAE). To our knowledge, there are only eight previously reported such cases in the history of the procedure. OBJECTIVE To identify clinical causes of CAE that can present to the emergency department (ED) and to understand the appropriate management of CAE. CASE REPORT(More)
