ABSTRACT
Preop Prior to surgery, patients should be fully evaluated by esophagogastroduodenos-
copy (EGD) and distal esophageal biopsy, esophageal manometry, 24-hour pH study (if no objective evidence of reflux or if symptoms are atypical), and barium swallow if hiatus hernia is large (>3-4 cm). Immediately prior to surgery, patients should have appropriate deep vein thrombosis (DVT) prophylaxis based on risk factors.
