Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign and locally invasive tumor. Massive bleeding because of vascularity of tumor and postoperative recurrence are potential problems of management. Endonasal approach reduces the rate of postoperative recurrence, intraoperative bleeding, and complications of surgery, time of operation and duration of hospitalization. In this article, we r...

we present a case of caustic ingestion by a 1.5-year-old boy. the caustic agent was drain opener which is a strong alkaline substance. children in iran and many other countries are still exposed to not “child proof” (child resistant packaging) toxic substance containers. ingestion of caustic agents may lead to necrosis, perforation, and strictures. substances that are ingested more frequently a...

endoscopic retrograde cholangiopancreatography (ercp) is a specific technique used to study the pancreatobiliary system that is performed in hepatogastroenterology centers. recent, common uses for therapeutic ercp are largely due to advanced imaging techniques such as magnetic resonance cholangiopancreatography and endosonography. in the united states alone, over 500,000 therapeutic ercp are pe...

inverted papillomas of the nose and paranasal sinuses are uncommon neoplasms, characterized by their tendency to occur and by their association with malignancy. in the past decade there has been a trend toward the use of endoscopic surgical techniques in the management of these tumors. this article presents the results of a prospective study of24 patients with inverted papilloma resected by the...

introduction: the aim of this study was to evaluate audiological outcomes following adenoidectomy by the classical method and by endoscopically-assisted adenoidectomy using a powered instrument (microdebrider).   materials and methods: this study was conducted in a tertiary care center. it included 40 patients divided into two equal groups of 20 each. group-a patients underwent classical adenoi...

Endoscopic radial artery harvesting (ERAH) is a feasible and attractive minimally invasive approach for conduit procurement, however there have been concerns about a potential neurological damage occurring at the harvest limb site secondary to injury of the radial nerve during endoscopic harvesting. We present a case of ERAH in which we evaluated intraoperatively the characteristics of radial n...

aim : to evaluate the role of  endoscopic ultrasonography (eus) in the diagnosis of gallbladder microlithiasis, sludge, and stone  in patients with clinical suspicion of cholecystitis, but with normal transabdominal ultrasonography (tus) during six months follow-up after laparosopic cholecystectomy (lct). background : endosonography has been shown to be highly sensitive in the detection of chol...

background: pancreatitis is a serious complication of endoscopic retrograde cholangiopancreatography (ercp) and may cause significant morbidity and even death. there is no effective prophylactic intervention for patients with average risk yet. this study aims to investigate preventive effect of aggressive hydration for post-ercp pancreatitis. materials and methods: in a double-blind controlled ...
