title: Long-term results after endoscopic pancreatic stent placement without pancreatic papillotomy in acute recurrent pancreatitis due to pancreas divisum.
abstract: BACKGROUND
  There is no consensus regarding the appropriate endoscopic treatment for acute recurrent pancreatitis associated with pancreas divisum. Endoscopic papillotomy of the minor papilla appears to yield improvement in most cases, but optimal depth and height have not been defined.
  
  
  METHODS
  Endoscopic pancreatic stent placement after minor papilla dilation was performed in 25 patients with pancreas divisum and acute recurrent pancreatitis. Five patients drank alcohol daily; no other cause of pancreatitis was detected. After adequate dilation, a transpapillary pancreatic stent (5F to 7F, 5 to 7 cm) was inserted over a guidewire into the dorsal duct. The stent was replaced twice, after 2- to 3-month intervals.
  
  
  RESULTS
  While stents were in place, no further episodes of pancreatitis occurred in 23 patients. However, dorsal duct changes of unknown clinical significance were seen in 21 cases. At mean follow-up of 24 months (range 3 to 70 months) after stent removal, 19 (76%) remained symptom free. Pancreatitis recurred in 6 patients during the follow-up after final stent removal; no further pancreatitis occurred in 2 of 3 who underwent repeat stent insertion. Complications in the series were minimal.
  
  
  CONCLUSIONS
  Endoscopic pancreatic stent placement after minor papilla and dorsal duct dilation, without endoscopic papillotomy, provided safe and effective endoscopic treatment in patients with pancreas divisum and acute recurrent pancreatitis.
