Quality of Life and Functional Outcomes After Intersphincteric Resection for Ultralow Rectal Cancer: A Prospective Observational Study
Diseases of the Colon & Rectum(2023)
摘要
BACKGROUND: Intersphincteric resection is the ultimate sphincter-preserving surgical technique for ultralow rectal cancer, but quality-of-life changes after surgery remain unclear. It is also unknown which questionnaire has better associations with functional results for capturing clinical variation in quality of life. OBJECTIVE: This study aimed to assess change in the quality of life and its correlation with functional outcomes among patients undergoing intersphincteric resection for ultralow rectal cancer. DESIGN: This was a prospective, observational, single-center study. SETTINGS: Colorectal surgery referral center. PATIENTS: Patients with ultralow rectal cancer who underwent intersphincteric resection were included. MAIN OUTCOME MEASURES: The primary outcomes were quality-of-life and functional results at 3 to 6, 12, and 24 months after ileostomy closure using validated questionnaires. The secondary outcome was the relationship between quality of life and neorectal function. RESULTS: A total of 102 patients (62.7% men) completed follow-up surveys. Wexner incontinence score and Kirwan's incontinence score significantly improved at 12 months after ileostomy reversal, but such improvement in low anterior resection syndrome score was proved until 24 months later (p = 0.01). Condition-specific quality-of-life domains improved over time, with significant changes in lifestyle (p = 0.02) and coping/behavior (p = 0.01), as well as the summary score of Fecal Incontinence Quality of Life ( p = 0.02) and visual analog scale score (p < 0.001). Among health-related quality-of-life domains, the subscale scores did not differ significantly. The functional systems scores were significantly correlated with all the domains of condition-specific quality-of-life but only a few health-related quality-of-life domains. Only weak to moderate associations with the functional outcomes were observed for both quality-of-life questionnaires. LIMITATIONS: Single-center data and limited sample size. CONCLUSIONS: Although low anterior resection syndrome persists for years after intersphincteric resection, condition-specific quality of life and functional outcomes improve over time. Compared to health-related quality-of-life questionnaires, condition-specific quality-of-life instruments might be preferable to evaluate changes in quality-of-life after surgery.
