Introduction: For four decades, TP-IAT has been performed to provide pain relief and preserve insulin function in patients(pts) with chronic/acute relapsing pancreatitis. Despite advances in surgical technique and perioperative management, TP-IAT remains a complex procedure with complicated post-operative management that is associated with high-rate of readmissions. We studied patterns and risk factors(RFs) associated with early readmissions post-TP-IAT with aim to identify modifiable causes to decrease rate of readmissions and improve the care for our patients.
Methods: 179 pts underwent TP-IAT(2014-2015).Demographics, pre- and peri-operative characteristics were compared between readmission(RG) and no readmission group(NRG) in univariable(UA) and multivariable(MVA) analyses. Timing, number, causes, temporal patterns of readmissions were examined.
Results:Of 179 pts, 79(44%) were readmitted within 3months, 99(55%) within 6 months, 125(70%) within one year of TP-IAT, with median number of readmissions 2(1-14) days and median time to first readmission 46(1-365) days. Demographics, pre- and peri-operative characteristics are shown(Table 1). In UA model initial length of stay(LOS) was significantly different between RG, 12 vs. 11 days for NRG; significance was lost in MVA. When intra- and post-operative events were studied in MVA, chyle leak associated with odds of readmission(p=0.04)(Table 2). Most common causes of readmission(CofR) were GI complications 87(70%), infection 78(63%), 36(29%)pain control(Table3). GI was common CofR throughout first year, frequency of ifx and pain management complications decreased over time. Glycemic control as CofR was an early event(Table4).
Conclusion: TP-IAT is associated with high rate of readmissions(55% at 6 months). Chyle leak is a RF for readmission, which may suggest complexity of specific original surgical cases. GI complications are most common CoR, persists throughout first year post-TP-IAT; more detailed review may provide identification of preventable GI complications in this cohort.
