Abstract No. 566 Safety and feasibility of ultrasound-guided gastric access for percutaneous transabdominal gastrostomy tube placement

Abstract

To evaluate the safety and feasibility of ultrasound guidance gastric access for percutaneous retrograde transabdominal gastrostomy (G) tube placement. Twenty-eight patients undergoing percutaneous retrograde transabdominal G tube placements utilizing ultrasound-guided gastric access at our institution from April 2015 to November 2017 were retrospectively identified. Technical success was defined as successful placement of a percutaneous “push-type” G tube with ultrasound-guided access. Chart review provided demographic data, clinical indication, procedural information (gastrostomy tube size fluoroscopy times, radiation dose), complications, dislodgements/ replacements and follow-up. Twenty-eight patients (15 male, 13 female; average age: 60.7 ± 15.4 years) undergoing 31 sonographic access transabdominal G tube placements were identified. All patients had successful placement of G tubes with ultrasound-guided gastric access. Two patients had subsequent G tube placements after the primary tube was removed secondary to resuming per oral intake for nutrition. There were no procedure-related complications. Three tubes became inadvertently dislodged requiring replacement. One access site infection was treated conservatively with antibiotics. Average fluoroscopy time was 2.7 ± 1.4 minutes and average radiation dose was 220 ± 202 μGym2. Ultrasound-guided access for gastrostomy placement is safe and feasible and can be performed with small fluoroscopy times resulting in decreased low and operator radiation dose.
