Outcomes after ileoanal pouch surgery in frail and older adults

Evidence from single-center studies suggests that ileal pouch-anal anastomosis (IPAA) can be safely performed in selected older patients with ulcerative colitis. The impact of age and frailty on surgical outcomes and hospital length of stay after IPAA has not been examined.

We identified all patients with ulcerative colitis who underwent total proctocolectomy or completion proctectomy with IPAA in the National Surgery Quality Improvement Program database from 2005-2012. We examined the associations of age and frailty trait count with length of hospital stay and surgical complications using multivariate regression.

IPAA was performed in 2493 patients with ulcerative colitis. Thirty-day mortality was 0.2% (n = 6). The majority of patients had no serious postoperative complications (age ≤50 y: 79.5%, age 51-60 y: 80.4%, and age >60 y: 79.1%). After multivariate risk adjustment, patients aged >60 y had a similar mean number of complications as patients aged ≤50 y (0.31 versus 0.35, P = 0.47) and a 0.8-d longer mean length of hospital stay (7.4 versus 8.2 d, P = 0.035). Compared to patients with zero frailty traits, a frailty trait count ≥1 was associated with a similar mean number of complications (0.31 versus 0.34, P = 0.36) and length of hospital stay (7.4 versus 7.7 d, P = 0.25).

In this analysis of patients undergoing IPAA at National Surgery Quality Improvement Program hospitals, surgical complications were not substantially increased in older patients or those with frailty traits. Older age was associated with a small increase in hospital length of stay. These findings suggest that IPAA is safe in selected older adults with ulcerative colitis.
