Introduction: Gastro Intestinal Tract (GIT) is an important site for wide variety of lesions which include congenital, inflammatory, neoplastic conditions. The invention of flexible fiber-optic endoscope is a very good achievement towards the diagnostic field. With the use of this facility direct vision of diseased mucosa and biopsy of mucosal lesions, therapeutic induction and photographic vis...

INTRODUCTION Luminal esophageal temperature (LET) monitoring is commonly employed during catheter ablation of atrial fibrillation (AF) to detect high esophageal temperatures during radiofrequency (RF) delivery along the posterior wall of the left atrium. However, it has been recently suggested that in some cases the esophageal probe itself may serve as an RF "antenna" and promote esophageal the...

BACKGROUND Atrio-esophageal fistula formation following radiofrequency ablation of left atrial tachyarrhythmias is a rare but devastating complication. Esophageal injuries are believed to be precursors of fistula formation and reported to occur in up to 47% of patients. This study investigates the incidence of esophageal lesions when real time esophageal temperature monitoring and temperature l...

abstract background: cancers are the second most common cause of non-accidental deaths in iran, after cardiovascular mortality. although most cases of esophageal squamous cell carcinoma (escc) in the usa and western populations have been attributed to high levels of exposure to tobacco and alcohol, but in iranian populations the other risk factors especially infectious agents have been postulat...

Background/Aims Endoscopic submucosal dissection (ESD) is currently considered the first-line treatment for eradication of superficial neoplasms esophagus in Eastern countries. However, West, particularly Latin America, experience with esophageal ESD still limited because high technical complexity required its execution. This study aimed to present results clinical application manage a American...

Objective: Atrio-esophageal fistula is an infrequent but devastating complication of catheter-based ablation of atrial fibrillation (AF). Thermal esophageal injury may be the precursor of atrio-esophageal fistula. Here, we evaluated the role of esophageal temperature monitoring in preventing thermal esophageal injury during pulmonary vein isolation for AF with radiofrequency energy. Methods: In...

INTRODUCTION Esophageal squamous cell carcinoma (ESCC) is the most common histological subtype of cancer in the upper and middle esophagus and is characterized by a high rate of mortality. The incidence of esophageal cancer varies greatly among regions of the world and occurs at a high frequency in Asia and South America. CASE PRESENTATION In our department, a 51-year-old man was diagnosed wi...

BACKGROUND Early esophageal mucosal carcinoma (M1 and M2) can be treated by ablation, or by endoscopic resection such as endoscopic mucosal resection (EMR) and endoscopic submucosal dissection. Endoscopic resection enables pathologic examination of resected specimens. We hereby report our experiences with early esophageal cancer and its endoscopically observed types, chromoendoscopy with Lugol'...

The epithelial cell adhesion molecule (EpCAM) is closely correlated with the occurrence and development of various cancers of epithelial origin. This study tested, for the first time, the ability of EpCAM aptamer SYL3C to detect EpCAM expression in 170 cases of esophageal cancer (EC) and precancerous lesions, as well as 20 cases of EC series samples, using immunofluorescence imaging analysis. C...

Acute mediastinitis is a low incidence pathology, but it associated with high mortality rate. Iatrogenic lesions are the most common cause of secondary to esophageal perforation. Early diagnosis and surgical treatment important factors in patients this condition. 83-year-old female patient, history left saphenectomy due venous insufficiency difficult intubation two days prior emergency consulta...
