Abstract
A retrospective review of 31 patients who developed acute colonic pseudo-obstruction (ACPO) after total joint arthroplasty was undertaken to determine predisposing factors related to, and outcomes following, therapeutic intervention. Comparison with all patients who underwent total joint arthroplasty revealed an overall 1.2% incidence of ACPO. There was a higher incidence of ACPO in patients undergoing sequential bilateral total knee arthroplasty (3.4%) compared with unilateral total knee arthroplasty (0.3%) and a higher incidence in patients undergoing revision total hip arthroplasty (5.6%) compared with primary total hip arthroplasty (1.4%). Additional risk factors for developing ACPO included slow postoperative mobilization and male gender. No association was found with respect to body mass index, age, comorbidity, anesthetic type, international normalized ratio level, or postoperative analgesia. There were no deaths, and 2 patients required operative intervention. The remaining cases of ACPO resolved with nonsurgical treatment. In all cases, there was a prolonged length of hospitalization (mean, 13.2 days) compared with all other arthroplasties performed at our institution (mean, 7.5 days).
