Laboratory Studies

Preoperative laboratory evaluation should include a complete blood count (CBC), a complete chemistry panel, liver function tests, thyroid function tests, a lipid profile, coagulation tests, serum iron and total iron binding capacity (TIBC), vitamin B-12, folic acid, blood typing, and urinalysis.

Next

Imaging Studies

  • Chest radiography
  • Ultrasonography of the gallbladder

Diagnostic Procedures

Upper endoscopy is performed to rule out intrinsic upper gastrointestinal disease, because, after gastric bypass surgery, the ability to nonsurgically visualize the distal stomach and the duodenum could be a challenge.
