Help with Sphincter of oddi II

Minnesota1

Looking for comments from those who have had stent placements for this condition and their outcomes. In sum, first went down this path 6 months after gallbladder removal. Became ill after a high fat mean, both liver and pancrease enzymes extremely high. Since then I have had 6 ERCP's with a variety of stent placements....3 being one stent in the pancreatic duct, the other 3 were multiple stents in the biliary duct. Had more success with the pancreatric stent placements, but those need to be removed a month later. I see Dr. Freeman at the U of MN close to where I live. He is well respected, but I feel I have run my course with him after this last ERCP 12 days ago. 8 days after this last procedure I ended up in the ER with the pains many are familiar with here....sever cramping and pain/nausea RUQ. He thinks they are clogged up (which is what happened the last time I had multiple stents placed) and will pull those out in 4 days. My question.....has anyone had surgery to help with SOD here? I think I have run my course with stents, although I would like to try to single stent again since it seemed to work while it was in. Have been thinking about getting a referral to Mayo since that is only 90 minutes away from me. Thoughts???
