Stent assisted percutaneous endoscopic necrosectomy for treating infected pancreatic necrosis / 中华胰腺病杂志

ABSTRACT

Objective To investigate the feasibility and safety of stent-assisted percutaneous endoscopic necrosectomy (SAPEN) in the treatment of infected pancreatic necrosis (IPN). Methods The patients with severe acute pancreatitis ( SAP) who received the treatment of SAPEN for IPN were sequentially included from January 2018 to September 2018 in the Eastern Theater General Hospital of People's Liberation Army. The demographic and clinical data were analyzed. The mortality and incidence of major organ dysfunctions were used as the primary observation endpoints. Results A total of 40 IPN patients were enrolled including 27 men and 13 women. The percutaneous covered stent placement procedures were successful in all cases;the median number of SAPEN operations was 1 ( range 1-3 ) , and no operation-related complications occurred. 32 patients were successfully cured by SAPEN, and the treatment effective rate was 80. 0％. 5 patients (12. 5％) required further open surgery after SAPEN. 12 patients developed new important organ dysfunction and 6 patients eventually died. Conclusions SAPEN was an effective and feasible minimally invasive method for the treatment of IPN, but its technical advantages still need to be further validated in large scale studies.
