Hi, Thanks for using healthcaremagic.com. Based on the characteristics of the dominant discomfort, i think you may have Oddi sphincter dysfunction(Pancreatic type): Pancreatic type, dominate the clinical manifestations of pancreatitis (paroxysmal pain in the epigastrium, generally postprandial), with periodic episodes of acute pancreatitis. Typical symptom: epigastric pain or in the right subcostal region, which lasts from 30 min to a few hours, radiates to the back or shoulder, is triggered by food and narcotic analgesic drugs (other characteristics → Diagnostic criteria); May appear immediately or a few years after the cholecystectomy and may resemble the symptoms prior to surgery. Palpation triggers moderate sensitivity in the central epigastrium or in the right subcostal region. Typical episodes of acute, often recurrent pancreatitis may occur. Pharmacological treatment: its effectiveness is poorly documented, useful mainly in patients with mild forms and moderate clinical symptoms and in all forms of type III ODE. Transdermal nitroglycerin or VS1, nifedipine VO or trimebutine VO is used. Endoscopic treatment: the benefits of endoscopic sphincterectomy are questionable. Up to now it is especially recommended in type I DEO and types II and III, if confirmed with manometry. In 10-20% of cases it is complicated by acute pancreatitis. Surgical treatment: transduodenal sphincteroplasty together with pancreatic septoplasty. Performed rarely, usually in case of recurrence of stenosis after endoscopic treatment.
