Perioperative Preparation of NOSES for Colorectal Cancer
Preoperative preparation, especially mechanical and/or antibiotic bowel preparation, is a routine procedure before colorectal examinations and surgeries. Bowel preparation aims to decrease bacterial load and stool burden and facilitates surgeries. With popularization of ERAS (Enhanced Recovery after Surgery), some have discontinued routine preoperative preparation; however, preparation is still vitally important in NOSES. It involves many aspects including bowel preparation, psychology preparation, and vaginal preparation for the female. Without preoperative preparation, outcomes may suffer.
