My apologies for not explaining what an endoscopy is. Here's the Wikipedia definition:
Endoscopy (pronounced /ɛnˈdɒskəpi/) means looking inside and typically refers to looking inside the body for medical reasons using an endoscope (pronounced /ˈɛndəskoʊp/), an instrument used to examine the interior of a hollow organ or cavity of the body. Unlike most other medical imaging devices, endoscopes are inserted directly into the organ. Endoscopy can also refer to using a borescope in technical situations where direct line-of-sight observation is not feasible.
Here's a link to a more detailed description of how an endoscopy is performed.
Raya is having it done so that the GI doctor can find the source of the blood that's been coming out of her the last couple of weeks (ulcer, tear in the tissue, etc) and make sure there's nothing serious. While she's under anesthesia, they'll pull out her old G tube and put in a different one that actually fits (I HOPE) and place the GJ tube which will bypass her stomach & send her formula directly into her small intestine & hopefully make her stop throwing up for a while.
(There you go, Donny, I hope that helps. :)
