Journal ArticleDOI
Esophageal Sphincter Device for Gastroesophageal Reflux Disease
Robert A. Ganz,Jeffrey H. Peters,Santiago Horgan,Willem A. Bemelman,Christy M. Dunst,Steven A. Edmundowicz,John C. Lipham,James D. Luketich,W. Scott Melvin,Brant K. Oelschlager,Steven Schlack-Haerer,C. Daniel Smith,C. Christopher Smith,Dan Dunn,Paul A. Taiganides +14 more
TL;DR: Exposure to esophageal acid decreased, reflux symptoms improved, and use of proton-pump inhibitors decreased in this single-group evaluation of 100 patients before and after sphincter augmentation with a magnetic device.
Journal ArticleDOI
The prevalence of lymph node metastases in patients with T1 esophageal adenocarcinoma a retrospective review of esophagectomy specimens.
Jessica M. Leers,Steven R. DeMeester,Arzu Oezcelik,Nancy Klipfel,Shahin Ayazi,Emmanuele Abate,Jörg Zehetner,John C. Lipham,Linda Chan,Jeffrey A. Hagen,Tom R. DeMeester +10 more
TL;DR: Adenocarcinoma invasive deeper than the muscularis mucosa is associated with a significant increase in the prevalence of lymph node metastases, and there is no "safe" level of invasion into the submucosa.
Journal ArticleDOI
Intraoperative Assessment of Perfusion of the Gastric Graft and Correlation With Anastomotic Leaks After Esophagectomy.
Jörg Zehetner,Steven R. DeMeester,Evan T. Alicuben,Daniel S. Oh,John C. Lipham,Jeffrey A. Hagen,Tom R. DeMeester +6 more
TL;DR: The aim of this study was to evaluate the use of laser-assisted fluorescent-dye angiography to assess perfusion in gastric grafts and determine the relationship between perfusion and anastomotic leaks.
Journal ArticleDOI
High intraepithelial eosinophil counts in esophageal squamous epithelium are not specific for eosinophilic esophagitis in adults.
Sonali Rodrigo,Gebran Abboud,Daniel S. Oh,Steven R. DeMeester,Jeffrey A. Hagen,John C. Lipham,Tom R. DeMeester,Parakrama Chandrasoma +7 more
TL;DR: All histologic features presently ascribed to IEE can occur in other esophageal diseases, notably GERD, and the finding of intraepithelial eosinophilia in any number is not specific for IEE.
Journal ArticleDOI
Obesity and Gastroesophageal Reflux: Quantifying the Association Between Body Mass Index, Esophageal Acid Exposure, and Lower Esophageal Sphincter Status in a Large Series of Patients with Reflux Symptoms
Shahin Ayazi,Jeffrey A. Hagen,Linda S. Chan,Steven R. DeMeester,Molly W. Lin,Ali Ayazi,Jessica M. Leers,Arzu Oezcelik,Farzaneh Banki,John C. Lipham,Tom R. DeMeester,Peter F. Crookes +11 more
TL;DR: An increase in body mass index is associated with an increase in esophageal acid exposure, whether BMI was examined as a continuous or as a categorical variable; 13% of the variation in esophileal acid Exposure may be attributable to variation in BMI.
