T Fastener Deply

Contributors: Marcus Jarboe, MD

T-fasteners (pre-loaded into a slotted 18 G needle and fixed to nylon suture) are sequentially advanced using the introducer needle under endoscopic visualization into the stomach. A total of 3-4 concentric T-fasteners are deployed and secured to the skin externally, leaving a central area large enough to accomodate the G-tube. A skin incision is then made in this space between the T-fasteners, and an 18 G needle is inserted into the stomach under endoscopic visualization. A guidewire (preferrably stiff such as Amplatz superstiff -Boston Scientific) is passed through the needle and sequential dilation is performed using Seldinger technique to the diameter of the intended tube. A balloon-based G-tube is then inserted over the guidewire and the balloon is inflated with water per manufacturer guidelines. The external bumper is pulled down against the skin to secure the tube at an appropriate depth.
