Objectives: Shorter hospital stay after pancreatoduodenectomy (PD) is a desired goal. Implementation of enhanced recovery after surgery (ERAS) protocols can possibly help in achieving this target.We aimed to determine the factors influencing the successful implementation of ERAS protocols by analyzing their relation to the surrogate marker of enhanced recovery, namely, duration of hospital stay.
Methods: A retrospective analysis of a prospectively maintained ERAS database of 208 consecutive patients who underwent PD at a tertiary referral care center was done.Results: Two hundred eight patients underwent a classical PD with a median duration of hospital stay of 8 days (range, 4-52 days) with an overall morbidity rate of 34.5% and a mortality rate of 3.8%. The 30-day readmission rate was 4% (8 patients). An elevated body mass index (relative risk, 1.098; 95% confidence interval, 1.015-1.188; P = 0.02) and respiratory comorbidities (relative risk, 8.024; 95% confidence interval, 2.018-31.904; P = 0.003) were independent factors resulting in a longer (>8 days) hospital stay.
Conclusions: Being overweight or obese and respiratory comorbidities are independent predictors of prolonged hospital stay despite the implementation of ERAS protocol. Hypoalbuminemia does not have a direct effect on hospital stay but may predispose the patient to the development of complications.
