Prediction of Postoperative Mortality in Patients With Organ Failure Following Pancreaticoduodenectomy

Abstract

Background Failure to rescue (FTR) patients with postoperative complications contribute to a significant proportion of postoperative mortality. Our main objective was to determine the risk factors for FTR among patients undergoing pancreaticoduodenectomy who suffered a life-threatening complication requiring intensive care unit (ICU) management. Materials and Methods Consecutive patients undergoing pancreaticoduodenectomy from 2011 to 2020 were reviewed retrospectively. Causes of organ failure were described as the one that most commonly contributed to patient’s transfer to ICU or death. Two groups were created based on whether patients had FTR and risk factors for FTR were compared. The impact of baseline characteristics, operative characteristics, and risk scoring on FTR was analyzed using multiple logistic regression. Results There were 19/58 (33%) FTR patients. Baseline, operative characteristics, postoperative complications, and length of hospital and ICU stay were similar between groups. However, a higher proportion of FTR patients experienced a postoperative pancreatic fistula (POPF) (16% vs 2.6%, P = .062). Among patients who experienced a POPF, the FTR group had a trend in delayed time from diagnosis to treatment (7 vs 23 hours, P=.131). Renal complications (OR 6.12, 95% CI, 1.23 to 38.43, P = .035) and time from POPF diagnosis to treatment (OR 1.05, 95% CI, 1.00 to 1.11, P = .036) were independent predictors of FTR by multivariable analysis. Conclusion The occurrence of certain postoperative complications such as renal complications as well as delayed timing of the management of POPF is predictive of FTR following pancreaticoduodenectomy, especially as delayed timing to treatment is a risk factor for FTR.
