BACKGROUND : Although 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.

METHODS : The 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.

RESULTS : Among 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).

CONCLUSIONS : Routine 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.
