title: Combined sinus tract endoscopy and endoscopic retrograde cholangiopancreatography in management of pancreatic necrosis and abscess.
abstract: BACKGROUND
  We report our experience of sinus tract endoscopy (STE) and endoscopic retrograde cholangiopancreatography (ERCP) in the treatment of pancreatic necrosis and abscess.
  
  
  METHODS
  Thirteen patients with extensive pancreatic necrosis were firstly managed with either percutaneous drainage (PD group; n = 9) or open necrosectomy (ON group; n = 4). Debridement of necrotic tissue was subsequently performed via the drain tract by STE. ERCP was performed only when there was a suspicious of persistent pancreatic duct disruption or choledocholithiasis.
  
  
  RESULTS
  In the PD group, the median number of STE sessions required was 3 (range 2-8). The median hospital and ICU stay were 84 days (range 29-163 days) and 0 day (range 0-64 days), respectively, with an overall success rate of 67%. In the ON group, the median number of STE sessions required was 6.5 (range 1-18). The median hospital and ICU stay were 82 days (range 58-194 days) and 19 days (range 4-24 days), respectively. No mortality or failure was noted in the latter group. ERCP was required in nine of 13 patients.
  
  
  CONCLUSIONS
  Combined ERCP and STE is a useful adjunct in treating pancreatic necrosis or abscess.
