Bedside postpyloric enteral tube placement using Kangaroo IRIS technology: a single-center case series.

Objectives: Postpyloric enteral feeding tubes (PPTs) are often placed endoscopically. This carries cost and capacity implications for hospitals with additional strain on endoscopy units during the SARS-CoV-2 pandemic. The Kangaroo Feeding Tube with IRIS Technology (IRIS) uses optical visualization to guide bedside placement, obviating the need for endoscopy. We describe a case series of bedside postpyloric enteral feeding tube placement using the IRIS tube.

Methods: This was a prospective, single-center case series over 12 mo. Conscious and sedated adult participants were included. Exclusion criteria were altered anatomy and need for endoscopy for other indications. IRIS placement was confirmed by contrast radiograph.

Results: Twenty attempts were made in 19 participants (13 women). The primary indication was intolerance of gastric feeding. The overall success rate was 75%. In sedated participants, 5 (83%) of 6 tubes were successful in 5 participants. In conscious participants, 10 (71%) of 14 tubes were successful in 14 participants. Placement failure in conscious participants was due to intolerance of the camera tip during nasal passage. The median procedure time was 13.5 min. In all cases, correct position as deemed by the operator was confirmed with contrast radiograph. No complications were observed.

Conclusions: To our knowledge, this is the largest single series of bedside postpyloric enteral feeding tube placement using the IRIS tube to date. The success rate and safety profile reported here, together with the potential benefits (reduced feeding delays, costs, and need for endoscopy) suggest that further, large-scale studies are warranted.
