Interventions

• Short term (10 day) low residue diet restriction — OTHER
  Patients will have an unrestricted diet (as opposed to a low residue diet restriction) 10 days after surgery.
• 6 week low residue diet restriction — OTHER
  Patients will be restricted to a low residue diet for 6 weeks after surgery. After this period, their diet will be unrestricted.

Study Details

The goal of this clinical trial is to learn if a 10 day low-residue diet restriction is better for bowel function and quality of life without increasing complications compared to a 6 week low-residue diet restriction after elective colon resection surgery. The main questions it aims to answer are: Does a shorter time period of low residue restriction result in a faster return to normal bowel function? Are there any differences in complication rate between a 10 day low-residue diet restriction compared to a 6 week low-residue diet restriction? Participants will be randomized to one of the two diet plans and will be asked to answer surveys about their bowel function and health care related quality of life at various time points for up to 3 months.
