- In patients undergoing radical resection for low-lying rectal cancer (LRC), higher BMI is associated with longer operative time, longer postoperative hospital stay, and increased incidence of postoperative complications.
- Higher BMI in this setting was not linked to survival outcomes.
Why this matters
- Radical resection is an optimal choice in patients with LRC.
- Study to investigate the effect of increased BMI in surgical outcomes in 792 patients who underwent LRC resection.
- Patients were stratified into 3 groups:
- Controls: BMI 2 (n=624).
- Overweight: BMI 25-30 kg/m2 (n=147).
- Obese: BMI ≥30 kg/m2 (n=21).
- Data source: colorectal cancer database of the Department of Gastrointestinal Surgery, West China Hospital, Sichuan University.
- Funding: Science and Technology Support Program, Science and Technology Department of Sichuan Province.
- High BMI was associated with significantly longer:
- Operative time: P<.001.>
- Postoperative hospital stay: P=.032.
- Pulmonary infection: P=.008.
- Anastomotic leakage: P=.029.
- Allergy: P=.017.
- Long-term complication: P=.034.
- Incisional hernia: P=.015.
- Retrospective data.
