Percutaneous Transesophageal Gastrostomy: Indications & Procedure Insights
with Lisa Rotellini-Coltvet and Dr. Alex Wallace
What do you do when conventional gastric tubes are not an option? In this week’s episode of BackTable, host Dr. Ally Baheti speaks with interventional radiologist Dr. Alex Wallace and physician assistant Lisa Rotellini-Colvet from the Mayo Clinic in Arizona about the percutaneous transesophageal gastrostomy (PTEG) procedure. The discussion explores how PTEG offers a transformative solution for patients who are not candidates for traditional transabdominal gastrostomy access. Suitable candidates for PTEG include individuals with malignancies, peritoneal carcinomatosis, prior gastrectomies, or ascites.
