The Latest Results and Future Directions of Research for Enhanced Recovery after Surgery in the Field of Colorectal Surgery / 이화의대지

ABSTRACT

Enhanced recovery after surgery (ERAS) aims to promote postoperative recovery in patients by minimizing the surgical stress response through evidence-based multimodal interventions. In 2023, updated clinical practice guidelines were published in North America, potentially superseding the most recent guidelines previously announced at the ERAS Society in 2019. This review compares and reviews these two guidelines to examine the principle of ERAS and items related to colorectal surgery and to introduce the latest relevant study results published within the last 5 years. In the pre-hospitalization stage, the concept of pre-hospitalization is emphasized; this involves checking and reinforcing the patient’s nutritional status and physical functional status before surgery. In the preoperative stage, large-scale studies have prompted a change in the recommendation of mechanical bowel preparation combined with oral antibiotics in elective colorectal surgery. In the intraoperative stage, laparoscopic surgery has become a widespread and important component of ERAS, and more technologically advanced single-incision laparoscopic surgery and robotic surgery are the focus of active research. Ileus-prevention items, such as opioid-sparing multimodal pain management and euvolemic fluid therapy, are recommended in the postoperative stage. The adoption of ERAS protocols is expanding to encompass a wide range of surgical procedures, clinical scenarios, healthcare institutions, and professional medical societies. In order to maximize the effect by increasing adherence to ERAS, medical staff must fully understand the clinical basis and meaning of each item, and the protocol must be maintained and developed steadily through a team approach and audit system.
