What is Percutaneous Radiologic Gastrostomy (PRG)?

Percutaneous radiologic gastrostomy (PRG) is the percutaneous placement of a feeding tube into the gastric lumen in patients requiring long-term enteral nutrition. It is an alternative to PEG (percutaneous endoscopic gastrostomy).

Indications include ALS, head-neck malignancy, stroke sequelae, severe dysphagia, neurological diseases, esophageal obstruction, and chronic nutritional insufficiency. Preferred when endoscopy is contraindicated (esophageal stricture).

Technique: stomach is inflated with air via nasogastric tube, anterior gastric wall is localized with ultrasound-fluoroscopy guidance, and after fixation with T-anchors, a 14-18F tube is placed. Complications include infection, bleeding, colon injury, and tube dislocation.

Symptoms

Dysphagia and nutritional insufficiency
Inability to feed orally
Aspiration pneumonia
Weight loss and malnutrition
Esophageal obstruction
Neurological swallowing disorder
Head and neck malignancy treatment
Chronic critical illness

Risk Factors

PEG contraindication
Esophageal stricture
Head and neck surgery
Stroke and dysmotility
Obesity (transillumination difficult)
Ascites
Gastric varices
Coagulation disorder

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Long-term feeding requirement (>30 days)
  • Recurrent aspiration pneumonia
  • Weight loss with malnutrition
  • PEG failure
  • Head-neck tumor treatment planning
  • Post-neurological injury dysmotility
