Habitual preoperative dietary fiber intake and complications after colorectal cancer surgery
JAMA Sep 13, 2021
Kok DE, Arron MNN, Huibregtse T, et al. - This cohort study demonstrated a lower risk of postoperative complications in relation to higher habitual dietary fiber intake before surgery among patients with colorectal cancer.
Patients with stage I to IV colorectal cancer (n = 1399) who had elective abdominal surgery were included.
A 204-item food frequency questionnaire was applied to evaluate habitual dietary fiber intake.
Occurrence of any complications and surgical complications in 397 patients (28%) and 235 patients (17%), respectively, was reported.
A lower risk of any complications (odds ratio [OR], 0.75) and surgical complications (OR, 0.76) was observed in relation to higher dietary fiber intake (per 10 g per day), whereas no link with anastomotic leakage was identified (OR, 0.97).
A link of higher dietary intake with any complications (OR, 0.64) was evident in females, whereas no association was found among males (OR, 0.79).
Fiber consumption from vegetables (per 1 g per day) was inversely related to any (OR, 0.90) and surgical (OR, 0.87) complications.
Improving preoperative dietary fiber consumption may be considered in future prehabilitation programs for colorectal cancer patients receiving surgery.
