Summary
A new prototype device for transgastric surgery offers superior, leak-resistant gastrotomy closure compared to standard clips and rivals hand-sewn methods, significantly reducing procedure time.
Area of Science:
- Minimally Invasive Surgery
- Surgical Device Development
- Gastrointestinal Endoscopy
Background:
- Transgastric endoscopy is explored as a less invasive surgical alternative.
- Effective and safe closure of transgastric incisions is a critical challenge.
- This study compares gastrotomy closure techniques in a porcine model.
Purpose of the Study:
- To evaluate the effectiveness of different gastrotomy closure methods.
- To compare leak pressures and closure times for various techniques.
- To assess a novel prototype device against standard methods.
Main Methods:
- Gastrotomies were created in porcine stomachs using a needle knife and CRE balloon.
- Closure methods included standard QuickClips, a prototype device, and hand-sewn stitches.
- Stomachs were pressurized to assess air and liquid leakage.
Main Results:
- The prototype device achieved the highest median air leak pressure (85 mmHg), significantly outperforming clips.
- Prototype closure time was approximately 5 minutes, faster than other methods.
- Hand-sewn closures (47 mmHg) were comparable to the prototype, while clips leaked earlier (33 mmHg).
Conclusions:
- The prototype device provides superior, leak-resistant gastrotomy closure.
- It significantly reduces procedure time compared to existing methods.
- This device shows promise for improving transgastric surgery safety and efficiency.
