ARTICLE HIGHLIGHTS
Research background
Consensus regarding the necessity for drainage has been formulated in the many management strategies for pancreatic trauma (PT).
Research motivation
Few studies have addressed the question of which drain types are more beneficial for PT patients.
Research objectives
To investigate whether sustained low negative pressure irrigation (NPI) suction drainage is superior to closed passive gravity (PG) drainage in PT patients.
Research methods
We performed a retrospective cohort study of consecutive patients who underwent pancreatic surgery at a tertiary trauma referral center between January 2009 and October 2021 in our PT database. The primary outcome was defined as the occurrence of severe complications (Clavien-Dindo grade ≥ Ⅲb). Multivariable logistic regression was used to model the primary outcome, and propensity score matching (PSM) was included in the regression-based sensitivity analysis.
Research results
In this study, 146 patients underwent initial PG drainage, and 50 underwent initial NPI suction drainage. In the entire cohort, a multivariable logistic regression model showed that the adjusted risk for severe complications was decreased with NPI suction drainage [14/50 (28.0%) vs 66/146 (45.2%); odds ratio (OR), 0.437; 95% confidence interval (CI): 0.203-0.940]. After 1:1 PSM, 44 matched pairs were identified. The proportion of each operative procedure performed for pancreatic injury-related and other intra-abdominal organ injury-related cases was comparable in the matched cohort. NPI suction drainage still showed a lower risk for severe complications [11/44 (25.0%) vs 21/44 (47.7%); OR: 0.365; 95%CI: 0.148-0.901].
Research conclusions
Initial NPI suction drainage could be recommended as a safe and effective alternative for managing complex PT patients.
Research perspectives
Further randomized, controlled trials are warranted to validate these results.
