OBJECTIVES: The primary aim of this study is to determine if patients with end-stage renal disease (ESRD) on peritoneal dialysis (PD) have a higher risk of developing acute pancreatitis (AP) than patients on hemodialysis (HD). The secondary aim is to compare the outcomes of AP between the two groups. METHOD: This is a retrospective case-control study. The study groups consisted of all patients initiated on HD and PD between January 1, 1998 and August 1, 2003. AP was identified using ICD-9 codes. Statistical analysis was carried out using Poisson regression, Kaplan-Meier curve, log-rank test, and Cox regression. RESULTS: One thousand two hundred and thirty-three and 160 eligible patients were identified in the HD and PD groups, respectively. Twenty-eight patients had AP. Eight patients were excluded as they had identifiable etiologies for AP. Of the remaining 20 patients with AP, 14 were in the HD group and 6 were in the PD group (p= 0.009). Incidence of AP was 18.4 per 1,000 person-years in the PD group and 6.5 per 1,000 person-years in the HD group (p= 0.033). Kaplan-Meier curves showed a significant difference in AP-free survival between the two groups (log-rank p= 0.026). Using time-dependent analysis, the hazard ratio for AP in PD patients after adjustment for age and sex was 3.94 (p= 0.006). There was no observed difference in length of hospital stay and ICU stay. All cases of AP were interstitial. There were no complications or deaths related to AP. CONCLUSION: PD is a risk factor for AP. There is no statistical difference in AP-related mortality and morbidity between HD and PD.
