Test for gut ischemia in chronic belly artery disease

This study looks at ways to promote early diagnosis of chronic mesenteric ischemia, a condition where the intestines don’t get enough blood over time. If you’re being evaluated for this problem, the trial may help ensure the right diagnosis happens sooner.

This study looks at how blood flows through the main vein of the liver (portal vein) in people with chronic narrowing of the gut's blood vessels. It may help doctors understand why some people get belly pain after eating.

This trial studies whether a surgical “release” of the celiac artery (to improve blood flow) helps people with MALS who have specific symptoms and artery narrowing. Some people will have a sham (placebo) procedure to compare outcomes, so you’ll be closely monitored either way.

This trial checks if a pressure measurement across a narrowed gut artery helps doctors decide if treatment is needed. It may help people with chronic gut artery blockages who are already scheduled for a procedure.

This study checks whether adding an extra, cross-body “transmural” evaluation (looking at inflammation throughout the bowel) improves care for adults with Crohn’s who are starting or receiving biologic (biotherapy) treatment. It uses close follow-up with stool calprotectin (a marker of gut inflammation) to see if this approach helps control inflammation.

This pilot study looks at markers in your blood that might help doctors tell if you have a serious bowel condition called acute mesenteric ischemia. You may be asked to participate if you have severe belly pain and need a special CT scan to check for this condition.
