Percutaneous Ultrasound Gastrostomy: First-in-Human Experience with the PUMA-G System

J Vasc Interv Radiol. 2020 May;31(5):808-811. doi: 10.1016/j.jvir.2019.12.002. Epub 2020 Apr 15.


Percutaneous ultrasound gastrostomy (PUG) technique was developed to allow for gastrostomy tube insertion to be performed solely under ultrasound guidance without need for fluoroscopy or endoscopy. This report discusses the new device, proposed PUG technique, and the first-in-human experience. Five patients had PUG tube insertion performed as part of a Health Canada approved investigational study. All procedures were successful with no complications within 30 days postprocedure. Mean total procedure time was 50 ± 13 minutes. Two of 5 procedures required temporary fluoroscopy use to localize the orogastric balloon position within the stomach to achieve magnetic gastropexy.
