Management of Barrett’s Esophagus: Results from a Compared to the group that did not progress, the group Retrospective Cohort of 1834 Patients that progressed was older (63.8 ± 13.5 vs. 68.8 ± 13.1. p < Craig S.

Evanston, IL CONCLUSIONS: In patients with BE without dysplasia, INTRODUCTION: Barrett’s esophagus (BE) is the most pre- refl ux control was associated with decreased risk of progres- dictive risk factor for development of esophageal adenocar- sion to LGD, HGD, or EAC. The results support the use of cinoma, a malignancy with the fastest increasing incidence refl ux control strategies such as PPI therapy or surgery in rate in the US. Based on the assumption that all patients patients with non-dysplastic BE. progress through low-grade dysplasia (LGD) to high-grade dysplasia (HGD) and fi nally to esophageal adenocarci- 232 noma (EAC), we were interested in studying factors that may affect the rate of progression to LGD or greater. We Prevalence, Impact and Predictors of Hospital Acquired were particularly interested in investigating the question Conditions After Major Surgical Resection for Cancer: A of whether control of refl ux, either surgically or medically, NSQIP Analysis protects patients from progression to dysplastic disease or * adenocarcinoma.
