Trocar Assist Percutaneous Abscess Drainage: A Novel Minimally Invasive Approach Reducing Complications in Infected Necrotizing Pancreatitis—A Retrospective Cohort Study

Background: Infected necrotizing pancreatitis (INP) requires effective drainage management. We introduce a novel technique, Trocar-Assisted Percutaneous Abscess Drainage (TAPAD), for direct placement of a double-lumen irrigation-suction tube and compare it with conventional 2-stage drainage. Methods: This retrospective cohort study included INP patients treated with the 2-stage method (n=98) or TAPAD (n=88). Outcomes included subsequent surgical requirements, complications, mortality, inflammatory markers, and ICU length of stay. Results: TAPAD significantly reduced the need for subsequent surgical intervention (OR=0.36, 95% CI: 0.16-0.82; P =0.02), abdominal bleeding (OR=0.41, 95% CI: 0.20-0.85; P =0.02), and ICU length of stay (HR=2.76, 95% CI: 1.89-4.02; P <0.001). Patients in the TAPAD group exhibited lower inflammatory marker levels on days 7 and 14 postintervention. Conclusion: TAPAD represents a promising alternative to conventional 2-stage drainage, offering reduced complications and improved clinical outcomes in the management of INP.
