Baxter Refik Saskin Andrew Calzavara David Gomez Colorectal Disease AbstractAimThe safety of nonoperative treatment for patients with transplanted kidneys who develop acute diverticulitis is unclear. Our primary aim was to examine the long‐term sequelae of nonoperative management in this group.MethodWe performed a population‐based retrospective cohort study using linked administrative databases housed at ICES in Ontario, Canada. We included adult (≥18 years) patients admitted with acute diverticulitis between April 2002 and December 2019. Patients with a functioning kidney transplant were compared with those without a transplant. The primary outcome was failure of conservative management (operation, drainage procedure or death due to acute diverticulitis) beyond 30 days. The cumulative incidence function and a Fine–Grey subdistribution hazard model were used to evaluate this outcome accounting for competing risks.ResultsWe examined 165 patients with transplanted kidneys and 74 095 without. Patients with transplanted kidneys were managed conservatively 81% of the time at the index event versus 86% in nontransplant patients. Short‐term outcomes were comparable, but cumulative failure of conservative management at 5 years occurred in 5.6% (95% CI 2.3%–11.1%) of patients with transplanted kidneys versus 2.1% (95% CI 2.0%–2.3%) in those without. Readmission for acute diverticulitis was also higher in transplanted patients at 5 years at 16.7% (95% CI 10.1%–24.7%) versus 11.6% (95% CI 11.3%–11.9%). Adjusted analyses showed increased failure of conservative management [subdistribution hazard ratio (sHR) 3.24, 95% CI 1.69–6.22] and readmissions (sHR 1.55, 95% CI 1.02–2.36) for patients with transplanted kidneys.ConclusionMost patients with transplanted kidneys are managed conservatively for acute diverticulitis. Although long‐term readmission and failure of conservative management is higher for this group than the nontransplant population, serious outcomes are infrequent, substantiating the safety of this approach. 10.1111/codi.16941 http://creativecommons.org/licenses/by-nc/4.0/ |
