Summary
The figure-of-8 suturing technique is the most effective for endoscopic gastrointestinal closure, demonstrating superior leakproof rates. This method offers a reliable solution for endoluminal surgery, enhancing patient safety.
Area of Science:
- Gastroenterology
- Minimally Invasive Surgery
- Endoscopic Surgery
Background:
- Reliable endoluminal closure is crucial for advancing endoluminal surgery.
- Flexible endoscopic suturing devices are available and can mimic surgical techniques.
- Evaluating optimal suturing techniques is essential for device efficacy.
Purpose of the Study:
- To determine the optimal endoluminal suturing technique using a flexible endoscopic suturing device.
- To compare the performance of single stitches, figure-of-8, and running suture patterns.
- To assess material consumption, operation time, and closure integrity.
Main Methods:
- Procedures were conducted on porcine stomach simulators.
- A 3-cm full-thickness incision was created and closed using an OverStitch device.
- Three techniques (single stitches, figure-of-8, running suture) were evaluated for time, sutures, and burst pressure.
Main Results:
- No statistically significant differences in suturing time were observed between techniques.
- The figure-of-8 technique required fewer sutures than the interrupted technique.
- The figure-of-8 pattern achieved significantly higher leakproof rates (85.5%) compared to other methods (50%).
Conclusions:
- The figure-of-8 suturing pattern is the preferred technique for endoscopic gastrointestinal closure.
- This technique demonstrates superior performance in ensuring leakproof closures.
- The findings support the figure-of-8 pattern for enhancing safety in endoluminal procedures.
