NOTES (Natural Orifice Transluminal Endoscopic Surgery) is an experimental surgical technique that performs operations through natural openings in the body without external incisions. This avoids scarring and reduces recovery time. NOTES procedures first began in the 1980s and have included cholecystectomies, appendectomies, and other abdominal surgeries. While still being developed, NOTES may eventually allow many operations to be done as outpatient procedures with even faster recovery times compared to laparoscopic surgery.
