objective: to investigate the importance of endoscopic nodular gastritis associated with helicobacter pylori infection in children. methods: in this prospective study, 220 consecutive patients (age range 2 to 15 years, mean age 9. 02 ±3 .3 ), 118 of them males (53. 6%) underwent upper endoscopy during evaluation of chronic abdominal pain. the appearance of nodular gastritis was observed during ...

We describe a case of bilateral massive conchae bullosa in a 76-year-old woman. She presented with a 2-year history of nasal obstruction and frontal headache. In light of these and other findings on anterior rhinoscopic and endoscopic examinations, we initially suspected nasal tumors. However, after a prebiopsy evaluation by computed tomography, we diagnosed bilateral massive conchae bullosa th...

Chromoendoscopy pertains to image-enhanced endoscopic techniques such as dye-based chromoendoscopy and electronic chromoendoscopy using narrow-band imaging, flexible spectral imaging color enhancement, and i-scan. Dye-based chromoendoscopy has been demonstrated to improve colorectal dysplasia detection in high-risk patients with long-term inflammatory bowel disease, and electronic chromoendosco...

A 10-year-old boy presented with left-sided nasal obstruction and epistaxis. Endoscopic evaluation revealed a polypoid mass in the vestibule arising from the lateral wall of the nasal cavity anteroinferior to the left inferior turbinate. Computed tomography (CT) scan showed a soft tissue opacity in the vestibule of the left nasal cavity. After the endoscopic excision of the mass, postoperative ...

Correlation of Visick grading was done with serial endoscopies in 19 patients operated for duodenal ulceration. Deeper mucosal lesions like ulceration showed good association with Visick grading (100%), while superficial mucosal lesions were mostly asymptomatic and therefore, caused disparity in grading. Moreover, as symptoms and endoscopic findings changed with passage of time, it was conclude...

Introduction: Congenital vomer agenesis is an extremely rare condition in which the vomer bone does not fully develop, which can lead to septal perforation. Case Report: We report two cases with a defect in the vomer bone in the posteroinferior portion of the septum, found accidentally while performing a pre-operative CT scan for nasal obstruction evaluation. They were diagnosed with congenital...

Gastric neuroendocrine carcinoma is a rare tumor which has a poor prognosis. Herein, we present a 55-year-old woman who presented with complaints of recurrent vomiting, hematemesis and weight loss. Endoscopic examination showed a large ulcerated mass in the antrum. Microscopic evaluation of the specimen taken through biopsy was compatible with a small round cell tumor. However, definitive histo...

Doxycycline induced mucosal injury to the esophagus and, rarely, stomach is an under appreciated cause of odonyphagia and chest pain. The diagnosis is dependent on a comprehensive exposure history and endoscopic evaluation. Once recognized, doxycycline induced ulceration is easily treated with cessation of the medication and gastric acid suppression. Our case report describes a classic descript...

BACKGROUND This report describes the clinical evaluation of a novel, low-cost, high-resolution endoscopic microscope for obtaining fluorescent images of the cellular morphology of the epithelium of regions of the esophagus with Barrett's metaplasia. This noninvasive point imaging system offers a method for obtaining real-time histologic information during endoscopy. OBJECTIVE The objective of...

Obesity is a growing problem in developed countries, and surgery is the most effective treatment in terms of weight loss and improving medical comorbidity in a high proportion of obese patients. Despite the advances in surgical techniques, some patients still develop acute and late postoperative complications, and an endoscopic evaluation is often required for diagnosis. Moreover, the high morb...
