title: Clinical study of B-mode ultrasound-guided retroperitoneal and abdominal catheter treatment of severe acute pancreatitis.
abstract: BACKGROUND
  The aim of this study was to investigate the clinical efficacy of B-mode ultrasound-guided retroperitoneal and abdominal catheter treatment of severe acute pancreatitis.
  
  
  METHODS
  A retrospective analysis was performed, regarding 68 patients diagnosed with severe acute pancreatitis in our hospital from May 2012 to May 2014. Patients were divided into an observation group (N.=38) and a control group (N.=30). Patients in the control group received conventional drug therapy and were given CT-guided catheter or surgical treatment when necessary. The observation group received conventional drug therapy + B-mode ultrasound-guided retroperitoneal and abdominal catheter drainage and lavage. The clinical efficacy and complication rate differences of the two groups of patients were compared and analyzed.
  
  
  RESULTS
  The total efficacy rates in the observation group were significantly higher than in the control group (P<0.05). The serum calcium levels of the observation group were obviously higher than that of the control group while their CRP levels and APACHE II scores were significantly lower (P<0.05). Complications were significantly lower in the observation group than in the control group (P<0.05).
  
  
  CONCLUSIONS
  B-mode ultrasound-guided biopsy for retroperitoneal and abdominal subcutaneous catheter drainage and lavage treatment of severe acute pancreatitis may improve the clinical effect and reduce complications.
