Application and Value of Percutaneous Catheter Drainage in Contemporary Surgical Treatment of Pancreatic Necrosis.

Acute necrotizing pancreatitis (ANP) is a relatively severe disease in clinical practice, and the selection of treatment strategies has a significant impact on the prognosis of patients. Percutaneous catheter drainage (PCD) serves as an effective treatment method and holds an important position in the treatment of ANP. With the in-depth development of medical research, the intervention strategies and management methods for ANP are constantly evolving. However, there is still controversy regarding when to adopt the step-up approach. This review aims to elaborate on the role of percutaneous catheter drainage, different drainage timings, and the evaluation of various drainage techniques, explore the current status and deficiencies of the research, with the expectation of providing more scientific and reasonable treatment decision-making basis for clinicians in dealing with ANP.
