Esophageal impaction can result in airway obstruction, stricture, or perforation. Perforation can be due to multiple mechanisms but is generally either mechanical (e.g.<unk>  bones) or via chemical corrosion (e.g. button battery)
Esophageal irritation can be perceived as<unk>  body (globus sensation)
Once the object has traversed the pylorus, it usually passes without issue
Exceptions: Irregular or sharp edges, particularly wide (>2.5cm) or long (>6cm) objects
Common<unk>  bodies:
Most common in children: coins (in the US), animal bones (outside the US)
Most common in adults: food bolus
Site of obstruction:
Cricopharyngeus (near C6) muscle is the most common (about 75%)
Aortic cross over the esophagus
Lower Esophageal Sphincter
