Mallory-Weiss tears are mucosal lacerations caused by forceful retching and are typically located at the gastroesophageal junction. Mallory-Weiss tears have not been described in the duodenum. We report of a Mallory-Weiss tear in the descending duodenum of a 57-year-old man who presented with hematemesis preceded by forceful retching. We discuss the pathophysiology of a duodenal injury in compa...

The term gastroesophageal reflux disease (GERD) describes any symptomatic condition or histopathologic alternation resulting from episodes of gastroesophageal reflux. It usually manifests as heartburn, regurgitation, or dysphagia, and predisposes to development of esophagitis, stricture, Barrett's metaplasia, esophageal adenocarcinoma, and a substantial decreased in the quality of life. Convent...

Four consecutive patients with a giant leiomyoma originating from the posterior aspect of the gastroesophageal junction were treated with full-thickness endoscopic retroflex dissection. A complete removal of the lesion was obtained in all cases. No complications were observed except for some degree of air filtration causing symptomatic pneumoperitoneum in one patient. Retroflex endoscopic full-...

Cholangiocarcinoma most commonly presents as painless progressive jaundice. We report a case occurring in a 56-year-old Chinese woman with an unusual presentation of progressive dysphagia and vomiting. Oesophageal manometric and barium studies were indicative of achalasia, and computed tomography confirmed the presence of cholangiocarcinoma extending to the gastroesophageal junction and proxima...

The significance of finding specialized intestinal epithelium localized to the region of the gastroesophageal junction is unclear. We tested the hypothesis that short segments of specialized intestinal epithelium are a consequence of gastroesophageal reflux disease and are premalignant. Two hundred forty-one patients with reflux symptoms underwent gastroscopy with rigorous biopsy. Barrett's eso...
