No matter what size prey, it's digested before it gets any where near the cloaca, which is where prolapses "happen". Prolapses do not result from the expulsion
of normal digested food...it takes some unusual circumstances, like if a snake swallowed something they cannot digest, or if they try to expel urate 'stones', etc.

Feeding too large of a meal can certainly make a snake regurgitate it's meal, and can sometimes cause injury to the snake on the way back up & out, but I've
never heard of a prolapsed esophagus.
