The Claim
CT-defined myosteatosis (mean skeletal muscle Hounsfield units <27.5) is associated with a 3- to 4-fold increase in 7-day and 30-day postoperative morbidity among patients undergoing colorectal cancer surgery who receive enhanced recovery after surgery (ERAS) alone.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Patients undergoing colorectal cancer surgery who receive enhanced recovery after surgery (ERAS) and have low muscle density on CT scans (indicating myosteatosis) experience three to four times higher rates of complications within 7 and 30 days after surgery compared to those without low muscle density.
See the scientific wording
CT-defined myosteatosis (mean skeletal muscle Hounsfield units <27.5) is associated with a 3- to 4-fold increase in 7-day and 30-day postoperative morbidity among patients undergoing colorectal cancer surgery who receive enhanced recovery after surgery (ERAS) alone (28% vs. 7% at 7 days; 40% vs. 11.6% at 30 days).
Fatty infiltration in muscles reduces their ability to produce energy efficiently, which weakens the body's capacity to handle the stress of surgery. This causes a stronger inflammatory reaction and poorer organ function after surgery, leading to more complications.
What the research says
1 studyPatients with fatty muscles seen on CT scans had about 3 to 4 times more complications after colorectal surgery if they only got standard care — and this study proved it by comparing those with and without fatty muscles. Prehabilitation helped reduce those complications, but the high risk in untreated patients was real.
