HPB SO10 - Evaluation of the impact of an Enhanced Recovery Pathway on clinical outcomes after Pancreaticoduodenectomy

Year: 2024

Type: article

Abstract: Background Southampton General Hospital (SGH) is a high-volume HPB centre with a well-established Enhanced Recovery After Surgery pathway (ERAS). Despite the morbidity associated with pancreatic surgery, there is a large body of evidence supporting the use of a multi-modal approach to accelerate patient recovery. Within SGH, ERAS is utilised for all patients undergoing Pancreaticoduodenectomy (PD). Initial assessment of the pathway in SGH demonstrated a reduction in length of stay. Since its implementation, ERAS has been modified to optimise the pathway. The aim of this study was to assess whether the impact of ERAS had progressed over time. Method Single centre retrospective analysis of patients undergoing open PD from 2007-2023. Pancreatic reconstruction was with pancreaticojejunostomy. Pre and Post ERAS data were analysed. Post ERAS data was subdivided into Early, Middle and Late implementation time phases. Length of Stay, Complications (Clavien-Dindo Grade 3 and above), Readmissions and Mortality were all examined. Non-parametric data analysis was undertaken with Kruskal-Wallis, Spearman rank correlation and Wilcoxon rank-sum tests. Significance further assessed with Multi-variate regression (MVR). All Data were analysed using STATA. Results Overall, 861 patients underwent an open PD, the yearly volume increasing with time. Mean age was 66 years, which did not change with time. With ERAS implementation, Median Length of Stay (LOS) fell 13 to 9 days (p<0.01) and there was no statistically significant increase in Grade 3 complications or Readmissions (p=0.931, p=0.163). Grade 3 complications increased LOS (p<0.01). Increased age led to a small increase in LOS (p<0.01). Median LOS across Early, Middle and Late ERAS periods was 10, 9 and 9 respectively. LOS did not consistently demonstrate a statistically significant improvement across ERAS phases (MVR p=0.387, K-Wallis p<0.05). Conclusion The implementation of ERAS significantly reduced the median LOS for patients undergoing PD, without increasing their risk of complications or readmissions. This benefit has also been safely maintained across the period of its implementation.
