The Claim

Among patients with CT-defined myosteatosis (mean skeletal muscle Hounsfield units <27.5), trimodal prehabilitation is associated with a 50% reduction in 7-day postoperative morbidity compared to enhanced recovery after surgery (ERAS) alone, with reported morbidity rates of 10% versus 28% (p=0.045); no such reduction is observed in patients without myosteatosis.

In plain English

In patients with low muscle quality detected by CT scan, a combination of pre-surgery exercise, nutrition, and psychological support reduces the rate of complications within seven days after surgery compared to standard recovery care, but this benefit does not occur in patients with normal muscle quality.

See the scientific wording

Among patients with CT-defined myosteatosis (mean skeletal muscle Hounsfield units <27.5), trimodal prehabilitation is associated with a 50% reduction in 7-day postoperative morbidity compared to enhanced recovery after surgery (ERAS) alone (10% vs. 28%, p=0.045), but no such benefit is observed in patients without myosteatosis.

Why this might work

Before surgery, exercise, better nutrition, and mental preparation help fatty muscles work better by making their energy factories stronger and reducing fat buildup inside muscle cells. This lets the muscles handle the stress of surgery better, so the body doesn't shut down organs or get infections as often after the operation.

  1. Study: Identifying Patients with Colorectal Cancer Likely to Benefit from a Trimodal Prehabilitation Prior to Surgery

    For patients with fatty muscles seen on CT scans, a pre-surgery program of exercise, nutrition, and mental support cut their risk of complications in the first week after surgery in half. But for patients without fatty muscles, the program didn’t help.
