Diagnosing CP with visual tests - question
Posted , 4 users are following.
How do visual tests diagnose CP? Is it through noticing the damage to the pancreas? Or do they notice inflammation/enlargement? Can a Pancreas be inflamed and not visible to EUS or MRCP?

Hello Marcus. From what I have read early CP can be missed by both MRCP and EUS, however it is unlikely to be missed by EUS. CP sometimes is broken up into "small-duct" and "large-duct" disease, and large duct is clearly apparent on MRCP, however the side branches (small-duct) can be hard to visualize. My doc's suspect CP and I have a clear MRCP, so if I have it (going to get an EUS soon) then it will likely be diagnosed as early small duct disease. This is also sometimes referred to as "minimal change chronic pancreatitis".

The only other ways of telling are from a fat stool test and/or a endoscopic secretin stimulation test. The former usually only shows up after the pancreas has been damaged over a long period of time (years to tens of years). The secretin test is suppose to be pretty accurate, and I have read it can show earlier/milder cases when EUS can't. Although, you typically read about 90% + accuracy for EUS, so it is considered a great test. I think MRCP is around the mid 80s for accuracy. CT is lower, although good for seeing stones in advanced cases.
I have been in pain (like you) since December 2016, and my MRCP in April was clean. This was 17 months into symptoms. I had my gallbladder removed as well, but that wasn't the cause and made things worse.
Does your pain get worse after eating fatty foods? That is a good sign it has something to due with the pancreas or bile system/gallbladder/liver. I live on around 20 grams of fat a day, as this keeps me out of pain for the most part. I also take pancreatic enzymes and bile acid (no gallbladder) and my stools went back to normal.

Hey shortie-- have they tried doing a resection of the pancreatic head or discussed doing some sort of whipple? I don't remember if you are diabetic yet or have stones, but a lot of journal papers described pretty decent pain relief with resection, while maintaining some sort of exocrine and endocrine function.

If you go tp/ait there are a few places in the US that specialize in this. Folks in Minnesota sort of pioneered this work I believe and they have some of the best outcomes. I have some journal article I can send you if you PM me.
Marcus-- sorry about hijacking the thread. Did you end up getting a scan done?

Hi kluesy,
I had already the EUS twice, and each time there was nothing wrong with the Pancreas, no sign of Chronic Pancreatitis. So I have no idea what's happening. I am getting so tired of this. Every day I have this s**t feeling.

2 clear EUS is a pretty good indication that the pancreas is good. Have you also had a MRCP? As shortie mentioned, are there any indications of increased liver enzymes (ALT/AST)?

Hi, thanks for your answer. I am going Lactose-free for now. Let's see what changes. Celiac I believe I was tested through a sample for intestine during an EUS.

Yea, I still don't know what's wrong with me. I just always have this discomfort rather than pain, feels like the pancreas. Just this bloated, swollen feeling inside of me. Do you have any advice which was a game changer? ( coming from you or your specialist)

Hmm. Raised bilirubin could be telling you something there. Some people have a non-threatening condition called Gilbert's syndrome, but if you never had raised levels in the past this may indicate that you are not delivering bile enough to the small intestines. This can cause bilirubin to back up into your liver and blood stream.
Have you had your gallbladder function checked (HIDA scan)? MRCP would show stones, but it doesn't indicate how well the gallbladder is working. Also, were your ALT and AST levels normal? If those are high it can indicate a fatty or inflamed liver.
