Journal ArticleDOI

TL;DR: This study suggests that antireflux surgery should not be advised with the expectation that patients with GERD will no longer need to take antisecretory medications or that the procedure will prevent esophageal cancer among those with GERd and Barrett esophagus.
Journal ArticleDOI
Long-term nonsurgical management of Barrett's esophagus with high-grade dysplasia.
Thomas G. Schnell,Stephen J. Sontag,Gregorio Chejfec,Gerard V. Aranha,Adrienne Metz,Susan O'Connell,Ulla J. Seidel,Amnon Sonnenberg +7 more
TL;DR: In this article, a 20-year period, patients were diagnosed and observed through an organized surveillance program at the Hines Veterans Affairs Hospital using pre-established endoscopists using preestablished endoscopic criteria.
Journal ArticleDOI

Nelson,George Triadafilopoulos,Francisco C. Ramirez,Judith Collins,Tiina K. Johnston,Kenneth R. McQuaid,Harinder S. Garewal,Richard E. Sampliner,Romeo Esquivel,Douglas J. Robertson +20 more
TL;DR: There is a strong association between results of baseline screening colonoscopy and rate of serious incident lesions during 5.5 years of surveillance and patients with 1 or 2 tubular adenomas less than 10 mm represent a low-risk group compared with other patients with colon neoplasia.
Journal ArticleDOI
Most asthmatics have gastroesophageal reflux with or without bronchodilator therapy.

TL;DR: Most adult asthmatics, regardless of the use of bronchodilator therapy, have abnormal gastroesophageal reflux manifested by increased reflux frequency, delayed acid clearance during the day and night, and diminished lower esophageAL sphincter pressures.
Journal ArticleDOI
Hiatal hernia size, Barrett’s length, and severity of acid reflux are all risk factors for esophageal adenocarcinoma
Benjamin Avidan,Amnon Sonnenberg,Thomas G. Schnell,Gregorio Chejfec,Gregorio Chejfec,Adrienne Metz,Stephen J. Sontag +6 more
TL;DR: High-grade dysplasia and esophageal adenocarcinoma seem to stem from an extreme and unfavorable constellation of all risk factors that are generally held responsible for the development of GERD and Barrett's esophagus.
