PEG Placement Considerations

Established Absolute Contraindications

The American Gastroenterological Association recommends avoiding PEG tube placement in patients with serious coagulation disorders, such as INR >1.5, due to increased risk of bleeding 1, 4, 5
Interposed organs between the abdominal wall and stomach, such as liver or colon, are a contraindication for PEG placement, as they increase the risk of visceral perforation 1, 2
Marked peritoneal carcinomatosis is a contraindication for PEG placement, as it can lead to seeding of the tumor along the PEG tract 1, 5
Severe ascites is a contraindication for PEG placement, although mild to moderate ascites is acceptable 1, 2
Active peritonitis is a contraindication for PEG placement, as it can lead to spread of infection 1, 5
Anorexia nervosa and severe psychosis are contraindications for PEG placement, as they can lead to poor patient outcomes 1
Clearly limited life expectancy is a contraindication for PEG placement, as it may not improve patient outcomes 1, 5

The American Gastroenterological Association identifies hemodynamic instability as a relative contraindication for PEG placement, as it can increase the risk of complications 6
Active gastrointestinal bleeding from peptic ulcer is a relative contraindication for PEG placement, as it can increase the risk of bleeding 6
Respiratory instability is a relative contraindication for PEG placement, as it can increase the risk of respiratory complications 6
Large midline wounds, chest tubes, abdominal mesh, and ostomies can make PEG placement more challenging, but should not necessarily preclude placement 6

The presence of pleural effusion does not increase the procedural risk of PEG placement, as the pleural space is anatomically distinct from the peritoneal cavity 1, 6
Patients with severe respiratory compromise from large pleural effusion may require addressing the effusion before PEG placement, as it can cause hemodynamic or respiratory instability 6
Underlying malignancy with limited life expectancy may constitute a contraindication for PEG placement, rather than the pleural effusion itself 1, 5
Patients with significant pleural effusions may require adequate anesthesia support during the procedure to ensure safe sedation 6

Verify hemodynamic and respiratory stability before scheduling PEG placement in patients with pleural effusion 6
Ensure proper site selection using transillumination and the "safe track technique" with needle aspiration to confirm no interposed organs 1, 6
Optimize sedation with anesthesia support if respiratory reserve is compromised in patients with pleural effusion 6
Consider chest tube position if present, to ensure it does not interfere with finding a safe abdominal wall window for PEG placement 6
