title: [Percutaneous nephroscopic necrosectomy for post-operatively resident infection of severe acute pancreatitis].
abstract: OBJECTIVE
  To investigate the method and effect of percutaneous nephroscopic necrosectomy (PNN) for post-operatively resident infection of severe acute pancreatitis (SAP).
  
  
  METHODS
  Data of the 15 SAP patients with post-operatively resident infection treated by PNN from June 2008 to December 2014 in Chinese People's Liberation Army General Hospital were reviewed. Twelve of the patients underwent the laparotomy within 1 week, 1 in 3(rd) week, 1 in 4(th) week and the other one on the 127(th) day. All of the referrals firstly received (multi-)percutaneous catheter drainage (PCD), and then PNN operation according to the disease, followed by continuous irrigation-drainage.
  
  
  RESULTS
  Eleven patients were healed after received only one PNN operation, 2 patients for twice, 1 for three times and 1 for four times. The average post-operative time of hospital stay was 66.2 days (10-223 days). The complications after operation contained colon fistula (n = 1), abdominal hemorrhage (n = 1), pancreatic pseudocyst (n = 1), severe pulmonary infection (n = 1). Three patients eventually died.
  
  
  CONCLUSIONS
  Percutaneous nephroscopic necrosectomy is a minimally invasive approach which could prevent the complicated re-laparotomy operation, result in less complication. It is an ideal method for treating SAP patients with post-operatively resident infection.
