Change in abdominal obesity after colon cancer surgery – effects of left-sided and right-sided colonic resection
Authors' conclusion
After 3 years follow-up survivors of CC accumulated abdominal adipose tissue. Notably, those who underwent left-sided colonic resection had increased VAT and SAT, whereas those who underwent right-sided colonic resection demonstrated solely increased SAT.

- 5% (95% CI: 2-7%, p < 0.01)
- Right-sided resection: increase in TAT
- 4% (95% CI: 1-7%, p < 0.01)
Change in VAT by sex · 3 years
