Diagnostic tests for digestive disorders

Colonoscopy   ERCP
Colonoscopy is a medical procedure where a long, flexible, tubular instrument called the colonoscope is used to view the entire inner lining of the colon (large intestine) and the rectum.   ERCP stands for endoscopic retrograde cholangio-pancreatography. ERCP is a diagnostic test to examine the duodenum, the papilla of Vater, the bile ducts, the gallbladder and the pancreatic duct.
Flexible sigmoidoscopy   Liver biopsy
Flexible sigmoidoscopy is a routine outpatient procedure. Sigmoidoscopy is the procedure by which a doctor inserts either a rigid or flexible fiber-optic tube into the rectum to examine the lower portion of the large intestine.   A liver biopsy is a medical procedure performed to obtain a small piece of liver tissue for diagnostic testing. Liver biopsy is used to diagnose the cause of chronic liver disease that results in elevated liver tests.
Lower GI Series (barium enema)   Upper GI (gastrointestinal) series
A lower GI series, or barium enema, is an x-ray test in which a white liquid, called barium, is placed into the rectum and colon through the anus to enhance x-ray pictures of the large bowel (colon).
  An upper GI (gastrointestinal) series is performed to assess frequent heartburn or stomach pain. It is used to help diagnose disorders and diseases of the upper gastrointestinal tract.
Upper endoscopy    
Upper endoscopy is a routine, outpatient procedure in which the inside of the upper digestive system is examined. Upper endoscopy allows a doctor to see inside the esophagus, stomach and top portions of the small intestine.
