The impact of restorative proctectomy versus permanent colostomy on health-related quality of life after rectal cancer surgery using the patient-generated index.

ABSTRACT

BACKGROUND: The impact of bowel dysfunction versus colostomy on quality of life after rectal cancer surgery is poorly understood. BACKGROUND: To evaluate the quality of life after rectal cancer surgery in patients with colostomy versus restorative proctectomy. METHODS: A mixed-methods study measuring quality of life using the Patient-Generated Index, patients were asked to list up to 5 areas of their life affected by their surgery. Areas were then weighted according to patients' preferences for improvement to generate a score from 0-100. The areas reported by patients were linked to the International Classification of Functioning for content analysis. Bowel dysfunction was measured using the low anterior resection syndrome score, and patients were then grouped according to (1) colostomy, (2) no/minor, or (3) major low anterior resection syndrome. Quality of life was compared between groups. RESULTS: Overall, 121 patients were included (colostomy n = 39, restorative proctectomy n = 82). There were no differences in demographics, neoadjuvant radiotherapy, or time to follow-up between groups. In the restorative proctectomy group, 53% had no/minor, and 47% had major low anterior resection syndrome. Overall, patients with colostomy had significantly lower quality-of-life scores than those with restorative proctectomy. However, patients with major low anterior resection syndrome scored similarly to those with colostomy. On content analysis, patients with colostomies reported more problems with sexual function, body image, and sports. Patients with restorative proctectomy reported more problems with sleep, using transportation, and taking care of themselves. CONCLUSION: Colostomy has a more detrimental impact on quality of life than restorative proctectomy. However, bowel dysfunction severity is important to consider. The patient experience between treatments differs.
