Abstract:
Ileus is a known early complication following kidney transplant (KTx). There is limited data largely from case reports documenting the occurrence of ileus in KTx patients. Potential risk factors include post-operative setting, steroid withdrawal, or even peritoneal sclerosis in patients with a history of peritoneal dialysis (PD). The aim of this study is to assess inpatient prevalence and outcomes of ileus in the same admission as the KTx occurred. METHODS: Case-control study using the NIS 2012-2016. The ICD9-10CM procedural codes for KTx were used to identify all patients that underwent KTx during the same admission. None were excluded. Patients with associated ileus were identified using ICD9-10CM diagnostic codes. The primary outcome was determining the odds of ileus in post-KTx patients. Secondary outcomes were inpatient mortality, postoperative complications, resource utilization, length of hospital stay (LOS), total hospitalization charges and costs. Propensity score matching was used to create a matching population for gender, age and Charlson Comorbidity Index. Multivariate analysis were used to adjust for income in patients’ zip code, hospital region, location, size and teaching status. RESULTS: A total of 89,065 KTx patients were identified, of which 16,880 were propensity score matched for the selected covariates. The mean patient age was 50 years, and 40% were female. On multivariate analysis, the odds of ileus in the KTx cohort was 3.90 ( P 〈 0.01) compared to patients who did not undergo KTx surgery. When patients that underwent KTx and developed ileus during the admission, they had greater adjusted odds of shock, TPN, AKI, multi-organ failure, post-op infection, Deep Vein Thrombosis, Pulmonary Embolism, and bleeding compared to patients with no KTx. In addition, those who developed ileus had greater hospitals costs, charges, and length of stay (LOS) (Table 1). CONCLUSION: Patients undergoing kidney transplant are more likely to develop ileus than patients who did not have kidney transplant surgery, confirming known reports documenting ileus in the early post-operative period. This cohort of patients who developed ileus following transplant have greater odds of post-operative complications, as well as increased morbidity, resource utilization and economic burden. Future studies should focus on elucidating the etiology of ileus following kidney transplant, as well as associated factors, and creating strategies to address it.
