Key result
Obesity in patients undergoing colorectal cancer surgery was associated with increased incidence of postoperative infection by 1.9%, as well as increased in-hospital mortality and length of stay.
Why the study?
Obesity adversely affects perioperative outcomes, but long-term outcomes do not appear affected by excess body weight, prompting examination of obesity and surgical outcomes in colorectal cancer.
Does obesity increase postoperative complications and in-hospital mortality in patients with colorectal cancer undergoing surgery?
Population
107,067 patients aged 20 years or older diagnosed with colorectal cancer who underwent surgery
Comparison
Obese patients vs matched non-obese controls
Design
Population-based matched retrospective database study

Chung et al. (2021) conducted a cohort in Colorectal cancer (n=107,067). Obesity vs. Non-obese was evaluated on postoperative infection (1.9% increase). Obesity in patients undergoing colorectal cancer surgery was associated with increased incidence of postoperative infection by 1.9%, as well as increased in-hospital mortality and length of stay.
