I would also like to know this aswell because unfortunately they never
really elaborated on it. I was just told that it would help me swallow
food much easier because I was having serious problems swallowing food
almost to the point where I couldn't at all without choking.

As for the pathology report, I don't recall. I will have to look for
it and report back.

A spring-tripped guide wire is deployed through the scope in order to guide
something safely down the esophagus. In the OP's case, it was most likely
done to guide a flexible dilator (probably a Savary dilator, which is the
most common guided dilator) down the esophagus in order to stretch a
stricture that they found, which could improve swallowing if the stricture
was tight enough to impair swallowing.

Such a guide is a semi-flexible wire, the first few centimeter of which is a
soft, flexible wound spring. The soft, spring-wound tip prevents the
possibility of ramming the otherwise rigid wire through the wall of the
stomach or esophagus. The spring-tipped guide has no therapeutic purpose by
itself - its function is to guide some therapeutic device (usually one that
is semi-rigid) safely so that *it* doesn't poke a hole in anything.

I don't really have a clue what an "esophageal cyst" is, but presumably they
found some kind of lesion in the esophagus. And if they indeed removed it,
surely they sent a specimen to pathology for evaluation to find out what it
is.
