Paraesophageal bronchogenic cyst was one of common mediastinal congenital cystic lesions of foregut origin. Because of an intimate embryologic relationship with the esophagus, they were usually found intramural (intramural esophageal bronchogenic cysts) with the local esophageal mucosa being intact and the paraesophageal bronchogenic cysts were rarely communicated with esophageal lumen. We repo...

Esophageal heating and subsequent thermal injury are concerning adverse effects of radiofrequency (RF) energy ablation on the posterior wall left atrium. Active intraluminal esophageal cooling may provide protection, allowing for effective delivery RF to overlying myocardium without collateral damage underlying esophagus. To evaluate impact luminal with a closed loop continuous flow irrigation ...

Automatic and accurate esophageal lesion classification segmentation is of great significance to clinically estimate the statuses diseases make suitable diagnostic schemes. Due individual variations visual similarities lesions in shapes, colors, textures, current clinical methods remain subject potential high-risk time-consumption issues. In this paper, we propose an Esophageal Lesion Network (...

BACKGROUND AND STUDY AIMS Multiple squamous cell carcinomas (SCCs) frequently arise in the upper aerodigestive tract, referred to as the field cancerization phenomenon. The aim of this study was to elucidate the detailed clinical features of second primary head and neck (H&N) SCCs arising in patients with esophageal SCC. PATIENTS AND METHODS A total of 818 patients underwent endoscopic resect...

BACKGROUND AND STUDY AIM The incidence of stricture formation caused by endoscopic submucosal dissection (ESD) for widespread lesions is high, and stricture formation can reduce quality of life. We evaluated the prophylactic efficacy of hybrid therapy using a locoregional steroid injection and polyglycolic acid (PGA) sheets with fibrin glue to prevent stricture formation after esophageal ESD in...

Background and objectives: Esophageal tuberculosis is a rare condition. It may be primary or secondary to tuberculosis elsewhere in the body. The present report describes the clinical features, endoscopic findings, radiologic abnormalities and outcome of anti-tuberculous treatment in a series of 14 verified cases of tuberculosis of the esophagus. Methods: All esophagogastroduodenoscopic examina...

BACKGROUND/AIMS The aim of this study was to analyze and propose a treatment strategy after endoscopic resection of superficial esophageal squamous cell carcinoma in a single institution. METHODS This is a retrospective review of 37 patients who were treated by endoscopic resection during a 6-year period. RESULTS The mean tumor size was 11.5±5.5 mm (range, 3 to 31 mm). Thirty-one lesions (8...

To determine whether dietary calcium supplementation affects esophageal precancerous lesions, 200 subjects with esophageal lesions in a high-risk area for esophageal cancer in China (Huixian, Henan) were randomly divided into 2 groups (100 subjects/group). Subjects in one group received an oral supplementation of calcium carbonate tablets (1200 mg of calcium daily), and subjects in the other gr...

Sodium polyacrylate (PANa) is a water-soluble, high-molecular compound, and its aqueous solution shows a very high viscosity and stringiness. In the present study, preventive effects of PANa on three kinds of esophageal lesions induced by gastric juice were examined in comparison with those of aceglutamide aluminum and sodium alginate. The influences of PANa on gastric contents were also studie...

BACKGROUND Gastroesophageal reflux disease is a very common affection, and esophageal involvement is particularly frequent. The means to effectively control symptoms and improve esophageal inflammation in these patients is to reduce esophageal acid exposure. For this purpose, we use gastric proton pump inhibitor, that can suppress gastric acid secretion. AIM To compare the effectiveness of tw...
