Many Canadians are undergoing MRI without screening for endoscopic clips. Although the risks of MRI to patients with endoscopic clips is unclear, the misclassification of some endoscopic clip models and inconsistent protocols for dealing with confirmed endoscopic clips call for further research and unified evidence-based endoscopic clip screening standards.

Graphical abstarct Purpose To report the results of the first-in-human trial evaluating the safety and efficacy of the percutaneous ultrasound gastrostomy (PUG) technique. Methods A prospective, industry-sponsored single-arm clinical trial of PUG insertion was performed in 25 adult patients under investigational device exemption (mean age 64 ± 15 years, 92% men, 80% inpatients, mean BMI 24.5 ± 2.7 kg/m2). A propensity score-matched retrospective cohort of 25 patients who received percutaneous radiologic gastrostomy (PRG) was generated as an institutional control (mean age 66 ± 14 years, 92% men, 80% inpatients, mean BMI 24.0 ± 2.7 kg/m2). Primary outcomes included successful insertion and 30-day procedure-related adverse events (AE’s). Secondary outcomes included procedural duration, sedation requirements, and hospital length of stay. Results All PUG procedures were successful, including 3/25 [12%] performed bedside within the ICU. There was no significant difference between PUG and PRG in rates of mild AE’s (3/25 [12%] for PUG and 7/25 [28%] for PRG, p = 0.16) or moderate AE’s (1/25 [4%] for PUG and 0/25 for PRG, p = 0.31). There were no severe AE’s or 30-day procedure-related mortality in either group. Procedural room time was longer for PUG (56.5 ± 14.1 min) than PRG (39.3 ± 15.0 min, p < 0.001). PUG procedure time was significantly shorter after a procedural enhancement, the incorporation of a Gauss meter to facilitate successful magnetic gastropexy. Length of stay for outpatients did not significantly differ (2.4 ± 0.5 days for PUG and 2.6 ± 1.0 days for PRG, p = 0.70). Conclusion PUG appears effective with a safety profile similar to PRG. Bedside point-of-care gastrostomy tube insertion using the PUG technique shows promise. Trial Registration Number: ClinicalTrials.gov ID NCT03575754. Graphical abstract
