Natural orifice transluminal endoscopic surgery (NOTES) is an experimental surgical technique whereby "scarless" abdominal operations can be performed with an endoscope passed through a natural orifice (mouth, urethra, anus, vagina, etc.) then through an internal incision in the stomach, vagina, bladder or colon, thus avoiding any external incisions or scars.
