Can share how it felt to have camera enter you lubang belakang.

You mention gall bladder. So the camera enter you lubang batang(pee hole)

Damm having camera enter lubang batang can't imagine how painful its gonna be

Endoscopy is procedure insert camera into body opening mouth, anus, penis so I ask how it felt to have a camera with wire get poke into your body opening

You sure boh simpe procedure need GA. Last time I go for one day surgery if want GA also need to add 2000++ as It will need to be administer by specialist. End up just local anesthesia
