Long-term Bowel Dysfunction and Decline in Quality of Life Following Surgery for Colon Cancer: Call for Personalized Screening and Treatment

Abstract

BACKGROUND: Differences in long-term outcomes regarding types of colon resections are inconclusive, precluding patient counseling, effective screening, and personalized treatment. OBJECTIVE: This study aimed to compare long-term bowel function and quality of life in patients who underwent right or left hemicolectomy or sigmoid colon resection. DESIGN: This was a multicenter cross-sectional study. SETTINGS: Seven Dutch hospitals participated in this study. PATIENTS: This study included patients who underwent right or left hemicolectomy or sigmoid colon resection without construction of a permanent stoma between 2009 and 2015. Patients who were deceased, mentally impaired, or living abroad were excluded. Eligible patients were sent the validated Defecation and Fecal Continence and Short-Form 36 questionnaires. MAIN OUTCOME MEASURES: Constipation, fecal incontinence (both Rome IV criteria), separate bowel symptoms, and generic quality of life were the main outcomes assessed. RESULTS: This study included 673 patients who underwent right hemicolectomy, 167 who underwent left hemicolectomy, and 284 who underwent sigmoid colon resection. The median follow-up was 56 months. Sigmoid colon resection increased the likelihood of constipation compared to right and left hemicolectomy (OR, 2.92; 95% CI, 1.80-4.75; p < 0.001 and OR, 1.93; 95% CI, 1.12-3.35; p = 0.019). Liquid incontinence and fecal urgency increased after right hemicolectomy compared to sigmoid colon resection (OR, 2.15; 95% CI, 1.47-3.16; p < 0.001 and OR, 2.01; 95% CI, 1.47-2.74; p < 0.001). Scores on quality-of-life domains were found to be significantly lower after right hemicolectomy. LIMITATIONS: Because of the cross-sectional design, longitudinal data are still lacking. CONCLUSIONS: Different long-term bowel function problems occur after right or left hemicolectomy or sigmoid colon resection. The latter seems to be associated with more constipation than right or left hemicolectomy. Liquid incontinence and fecal urgency seem to be associated with right hemicolectomy, which may explain the decline in physical and mental generic quality of life of these patients.
