Endoscopy is a set of Minimally Invasive Techniques (MIT) that uses cameras going through small incisions or natural body openings in order to diagnose and treat disease with reduced body cavity invasion.
Advantages:
Less postoperative pain due to minor trauma.
Shorter anesthesia.
Quicker recovery time.
Reduction in the rate of complications.
Better cosmetic effect.
Some examples:
Laparoscopic spaying.
Non-invasive examinations and biopsies.
Removal of foreign bodies (in airways, digestive tract, ears...)
