After surgery for low rectal cancer, patients who received a combined program of psychological, sleep, and nutritional support were significantly less likely to experience severe bowel control problems and had better sexual function than those who received standard care. This finding is from the abstract summary - full study details were not available.
Claim Context
After curative resection for low rectal cancer, an integrative psychosocial, sleep, and nutritional program reduces the prevalence of major anorectal dysfunction (LARS) by 17.5 percentage points and improves sexual function (IIEF-5/FSFI) compared to standard ERAS-based care.
“lower major LARS prevalence (28.7 % vs 46.2 %), and higher IIEF-5/FSFI scores.”

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether this specific integrative program consistently reduces major LARS and improves sexual function across diverse surgical centers and patient populations after low rectal resection.
A systematic review and meta-analysis of all RCTs measuring LARS score (categorized as major/minor/no) and IIEF-5/FSFI scores at 12 and 24 months in patients undergoing low rectal resection, comparing integrated psychosocial-sleep-nutrition programs to standard care, with standardized assessment tools and adjustment for nerve-sparing status.
That the intervention directly causes improvements in bowel and sexual function by isolating its effect from surgical or recovery variables.
A double-blind RCT with 300 patients undergoing low rectal resection, randomized to full integrative program (including pelvic floor therapy, nutritional fiber modulation, stress reduction) or standard care with sham interventions, measuring LARS score (categorized) and IIEF-5/FSFI at baseline, 6, 12, and 24 months, with blinded assessors.
Whether patients who adhere to pelvic health, nutrition, and stress management practices after surgery have lower rates of LARS and better sexual function over time.
A prospective cohort study following 600 patients after low rectal resection, tracking daily adherence to pelvic floor exercises, dietary fiber intake, and psychological coping, and measuring LARS and IIEF-5/FSFI at 6, 12, and 24 months, adjusting for surgical technique and nerve preservation.
Whether patients with major LARS at 24 months are less likely to have received the integrative program.
A case-control study comparing 150 patients with major LARS (score ≥19) to 150 with no/minor LARS, assessing prior exposure to the integrative program and controlling for tumor location, nerve-sparing status, and preoperative bowel function.
Whether patients reporting better bowel and sexual function at 24 months are more likely to have engaged in the intervention components.
A cross-sectional survey of 500 patients at 24 months post-surgery, measuring self-reported LARS severity, IIEF-5/FSFI scores, and adherence to sleep, nutrition, and psychological practices.
