Surgery Shelf Prep!

Achalasia can be tricky, and it is absolutely fair game for the Surgery Shelf. In this episode of Surgery Shelf Prep!, Chris and Mars break down the classic presentation of progressive dysphagia to both solids and liquids, regurgitation of undigested food, chest pain, and weight loss.
