I am 34 year old female who was hospitalized with my first bout of acute pancreatits a 5 weeks ago. Elevated amylase and lipase, and ultrasound confirmed non-gallstone pancreatitis. Alcohol trigger suspected as other common triggers ruled out. I was released after 5 days later with still elevated enzyme levels, but clinically doing much better. I followed up with the attending weekly and labs continued to show elevated enzyme levels close to 3X normal range. CT scan 2 weeks ago confirmed existence of pancreatitis with no biliary obstruction. I saw a gastroenterologist yesterday who re-did labs and ordered an MRI/MRCP to be taken in three weeks to give a chance for pancretitis to resolve. Clinically I feel extremely fine, but I have changed by diet considerably since hospital stay -- no alcohol and very light, non-fat foods. Questions: (1) if there is a biliary obstruction (e.g., sludge/crystals in gallbladder) will pancreatitis resolve without removal of obstruction?; (2) Is MRI/MRCP the best way to rule out obstructions not observable on CT scan/ultrasound or other physical triggers?; (3) What other causes might the procedure uncover?; (4) What's the next step if this procedure does not uncover any causes?; (5) Should I seek a second opinion from another gastroenterologist to confirm that the MRI/MRCP is the best course of action at this point?
