Trends and Variations in Drain Use Following Pancreatoduodenectomy: Is Early Drain Removal Becoming More Common?

Abstract

AbstractBackgroundAlthough previous studies have noted the potential benefit of early drain removal (EDR) after pancreatoduodenectomy (PD), there is a paucity of data on the timing of drain removal utilizing a national database that reflect the “real world” setting. Given the ongoing controversy related to PD drain use and management, we sought to define trends in drain use among a large national cohort, as well as identify factors associated with EDR following PD.MethodsThe ACS NSQIP targeted pancreatectomy database was used to identify patients who underwent PD between 2014 and 2020. The trend in proportion of patients with EDR (removal ≤ POD3) as well as predictors of EDR were assessed. Risk‐adjusted postoperative outcomes were evaluated by multivariable regression analysis.ResultsAmong 14,356 patients, 16.2% of patients (N = 2324) experienced EDR, and the proportion of patients with EDR increased by 68% over the study period (2014: 10.9% vs. 2020: 18.3%, p < 0.001). Higher drain fluid amylase on POD1‐3 [LogWorth (LW) = 44.3], operative time (LW = 33.2), and use of minimally invasive surgery (LW = 14.0) were associated with EDR. Additionally, EDR was associated with decreased risk of overall and serious morbidity, PD‐related morbidity (e.g., pancreatic fistula), reoperation, prolonged length of stay and readmission (all p < 0.05).ConclusionsRoutine drain placement remains a common practice among most surgeons. EDR following PD increased over time was associated with lower post‐operative complications and shorter LOS. Despite evidence that EDR was safe and may even be associated with lower complications, only 1 in 6 patients were managed with EDR.
