Abstract: Objective   To investigate the clinical efficacy of percutaneous catheterization combined with irrigation and drainage in the treatment of infected pancreatic necrosis.  Methods   Data of 10 patients with infectious peripancreatic necrosis admitted to our department from January 2018 to June 2022 who received puncture and catheter irrigation and drainage treatment were collated and analyzed,and the drainage time,recovery and complications of patients were recorded.  Results   All the 9 patients recovered after puncture irrigation and drainage treatment,and 1 patient failed puncture catheter irrigation and drainage treatment and was cured after open debridement.The average hospitalization time of irrigation and drainage was 32 days,and no complications occurred.  Conclusion   Percutaneous progressive replacement irrigation and drainage is minimally invasive and effective.It can be used in the treatment of infectious peripancreatic necrosis in some patients alone.It is worth promoting.
