What a sticture?

Answer 1

A stricture is a hardened band of tissue that often forms in the digestive tract. This can make swallowing difficult - often leading to regurgitation of food. This is usually treated with an endoscope (a device that goes down the throat) with an angioplasty balloon attached to it, the balloon expands and "pops" this band open so that the patient can properly swallow and eat again.
