Can a doctor via colonoscopy see the level of inflammation in the intestines? Does it require a biopsy? Are there any blood tests that can determine?

Not really: Colonoscopy can reveal masses and polyps (larger issues). If you are looking at tissue lining inflammation, or 'leaky gut' syndrome, there are several labs that have kits to test for this either by blood or by stool analysis. If it's to determine Chron's or Ulcerative colitis, there are other blood, GI tests, endoscopic imaging, ultrasound, (blue) dye during colonoscopy looking for inflammation. ...Read more

Add exercise also.: Atonic colon can be due to the absence of myenteric plexus or overuse of laxatives. If your colonoscopy and ct scan were normal, increased water intake, exercise and a high fiber diet will help. You had used lactulose, fruits, prunes, fiber, now add daily exercise, lots of water and stool softeners. I suppose you already see a gastroenterologist. Have you explored ibs as a possible cause ? ...Read more

Can normal CT scan, stool and blood tests, colonoscopy, gallblader us and hida scan, upper endoscopy (gerd, gastritis) rule out pancreatic cancer?

Only one of those : Most of those tests won't tell you anything about pancreas. Only one is ct scan.A perfectly normal ct with IV contrast goes a long way in saying you have a normal pancreas.Mri might give more info but not usually a screening test. ...Read more
