Assessing the benefits of repeated esophagogastroduodenoscopy at a specialized center before gastric and esophageal cancer surgery.

Patients are referred after an esophagogastroduodenoscopy (EGD) at a secondary healthcare facility. The EGD is repeated at the specialized EGC center before determining a surgical treatment strategy.
