Perioperative Preparation of NOSES

Preoperative preparation, especially bowel preparation, is a routine procedure before colorectal examinations and surgeries. Bowel preparation aims to clean the bowel and facilitate surgeries. With the popularization of Enhanced Recovery After Surgery (ERAS), the contents of preoperative preparation are constantly adjusted and improved. However, due to the particularity in the surgical procedures of NOSES, preoperative preparation is still vitally important. It involves many aspects including bowel preparation, vaginal preparation for females, and psychological preparation for patients. The most satisfactory surgical effects cannot be achieved without a comprehensive preoperative preparation.
