title: Endoscopic treatment of painful chronic pancreatitis: evaluation of a new flexible multiperforated plastic stent.
abstract: OBJECTIVE
  Endoscopic stents are a validated treatment for painful chronic calcifying pancreatitis (CCP). Biliary-type stents are the most commonly used, but have certain drawbacks. The aim of this single-center retrospective study was to evaluate the feasibility, and the short- and medium-term efficacy of a new pancreatic stent (Johlin model, Cook) for pain relief.
  
  
  METHODS
  Thirteen patients with painful CCP were treated with a Johlin stent. Stent specifications were studied as well as feasibility and efficacy. Success was defined as relief of pain.
  
  
  RESULTS
  There was no placement failure with the initial stent, which was 13.4+/-2.1cm in length and 9.8+/-0.6 Fr in diameter. Immediate total pain relief following stenting occurred in 11 patients. The average follow-up time was 11+/-7 months (range 1.5-24 months). Stents were left in place for 4.5+/-3 months (range 0.5-13.5 months). At the end of follow-up, endoscopic treatment was considered effective in 12 patients. Endoscopic retrograde cholangiopancreatographic (ERCP) complications consisted of uncomplicated acute pancreatitis (10%).
  
  
  CONCLUSIONS
  Pancreatic stenting using the Johlin stent (Cook) is feasible, has no particular adverse events and is effective for immediate as well as medium-term pain improvement.
