<unk> (NOTES) is an experimental surgical technique whereby abdominal and thoracic operations can be performed without any scars, or with very tiny ones. The procedure is performed through a hollow organ by passing surgical instruments and a tiny camera through a<unk><unk>  (mouth, urethra, anus, etc.). The patients recover more quickly and experience less pain and better cosmesis. The postoperative complications such as wound infections and hernias are significantly reduced.
Animal models and cadavers have been used to demonstrate that NOTES procedures are safe and feasible. Some of the NOTES applications are abdominal cavity screening, internal organs biopsy, appendectomy, cholecystectomy, tubal ligation, gastrojejunostomy, partial hysterectomy, oophorectomy, colorectal resection and trans-esophageal myotomy.
