Prehabilitation strategies for intestinal function in colorectal cancer patients with intestinal obstruction under the ERAS concept

Colorectal cancer patients with intestinal obstruction often require emergency surgery and face complications such as anastomotic leakage, intra-abdominal infection, and anastomotic edema, which exacerbate surgical stress responses and impair postoperative recovery. Perioperative measures under the enhanced recovery after surgery concept can mitigate these stressors and reduce complications. Prehabilitation strategies for intestinal function enable the conversion of emergency surgery to planned surgery, improving inflammatory responses, nutritional status, and immune function, while enhancing surgical quality and promoting early postoperative recovery.
