What Patients Undergoing Gastrointestinal Endoscopic Procedures Should Receive Antibiotic Prophylaxis?

Additional Populations to Consider. Previously, the International Society for Peritoneal Dialysis recommended that patients on peritoneal dialysis receive prophylactic antibiotics and empty their abdomen of dialysate prior to colonoscopy. This recommendation has been removed from the 2010 guidelines.¹⁸ There is also no indication that patients with synthetic vascular grafts or cardiac devices should receive prophylactic antibiotics prior to routine GI endoscopy.¹⁹ The American Academy of Orthopaedic Surgeons no longer recommends that patients with joint replacements receive antibiotic prophylaxis prior to GI endoscopy.²⁰

Back to the Case

The older gentleman with a prosthetic valve undergoing colonoscopy should not receive prophylactic antibiotics, because even in the setting of valvulopathy, colonoscopy does not pose a significant risk for infective endocarditis. The young patient with severe choledocholithiasis should be placed on prophylactic antibiotics because she has continued biliary obstruction, which could result in a cholangitis after ERCP.

Bottom Line

Prophylactic antibiotics are not recommended for any patient undergoing routine endoscopy or colonoscopy. They are indicated for patients with bleeding esophageal varices and for patients who undergo esophageal stricture dilation, PEG placement, or pseudocyst or cyst drainage, and those with continued biliary obstruction undergoing ERCP as summarized in Table 1.
