Summary
The loop-torque maneuver simplifies enteroclysis catheter intubation using a modified guidewire. This technique successfully intubated all patients with reduced discomfort compared to the double-back maneuver.
Area of Science:
- Gastroenterology
- Medical Devices
- Surgical Techniques
Background:
- Enteroclysis catheter intubation can be challenging.
- Existing guidewires may lead to catheter coiling or engagement with anatomical structures.
- Alternative maneuvers are needed to improve success rates and patient comfort.
Purpose of the Study:
- To introduce and evaluate the loop-torque maneuver for enteroclysis catheter intubation.
- To assess the efficacy and patient comfort of the loop-torque maneuver compared to the double-back maneuver.
Main Methods:
- A modified braided stainless steel guidewire, 26 cm longer than standard, was used.
- A loop was created in the proximal end of the guidewire to facilitate torquing.
- The loop-torque maneuver was applied to facilitate catheter passage.
Main Results:
- The loop-torque maneuver resulted in successful intubation in all patients.
- Patients reported less discomfort with the loop-torque maneuver compared to the double-back maneuver.
- The modified guidewire design effectively managed catheter engagement with the greater curvature or fundus.
Conclusions:
- The loop-torque maneuver is an effective and well-tolerated technique for enteroclysis catheter intubation.
- This modified approach offers a valuable alternative for challenging intubations.
- Further studies should explore broader applications of this technique.
