Core Tip

Core tip: This retrospective study investigated infection recurrence following successful minimally invasive treatment in infected pancreatic necrosis (IPN) patients. Our data demonstrated that infection recurred in 7.30% of IPN patients after drainage catheter removal. This can be predicted by white blood cell count, serum C-reactive protein, and procalcitonin levels measured at the time of catheter removal, and length of the catheter measured by computerized tomography scan. In particular, white blood cell count and serum procalcitonin level were highly sensitive and specific for predicting infection recurrence. These factors should be considered before removing the drainage catheters following minimally invasive treatment in IPN patients.
