title: Post-ERCP pancreatitis rates do not differ between needle-knife and pull-type pancreatic sphincterotomy techniques: a multiendoscopist 13-year experience.
abstract: BACKGROUND
  Pancreatic sphincterotomy is one of several factors associated with an increased risk of post-ERCP pancreatitis (PEP). The needle-knife pancreatic sphincterotomy technique (NKS) is purported to result in less-frequent post-ERCP pancreatitis compared with a standard pull-type sphincterotomy (PTS).
  
  
  OBJECTIVE
  Our purpose was to analyze the experience with both endoscopic pancreatic sphincterotomy (EPS) techniques with respect to post-ERCP pancreatitis at a single tertiary-level referral center.
  
  
  METHODS
  Retrospective analysis.
  
  
  METHODS
  Tertiary-care medical center (Charleston, South Carolina).
  
  
  METHODS
  Patients without chronic pancreatitis and with normal retrograde pancreatogram who underwent EPS between 1994 and 2007 were identified. Patients were excluded for the following reasons: pancreatic stent not placed, both sphincterotomy techniques used, any balloon dilation of the ampullary orifice, precut or access papillotomy, pancreas divisum.
  
  
  RESULTS
  A total of 481 patients were identified and underwent 510 ERCPs. Indications for ERCP were recurrent pancreatic-type pain (n = 353) or pancreatitis (n = 157). NKS was used for 395 of 510 (77.5%) cases versus 115 of 510 (22.5%) in which PTS was used. The incidence of post-ERCP pancreatitis was no different between NKS (25/395, 6.4%) and PTS (9/115, 7.8%). Most cases were mild pancreatitis; a single episode of severe PEP occurred in each group.
  
  
  CONCLUSIONS
  The risk of post-ERCP pancreatitis does not differ between EPS techniques when performed at a high-volume pancreaticobiliary referral center when using routine prophylactic pancreatic duct stent placement.
