Bowel welding technique in dogs and cats using a diode laser: an experimental study

Area of Science:

• Veterinary Surgery
• Surgical Technology
• Laser Applications in Medicine

Background:

• Minimally invasive surgical techniques are advancing in veterinary medicine.
• Laser technology offers potential for precise tissue cutting and sealing.
• Current methods for bowel anastomosis require careful technique and can have complications.

Purpose of the Study:

• To develop and evaluate a novel laser bowel welding technique for dogs and cats.
• To determine optimal laser parameters for cutting and sealing bowel tissue.
• To assess the efficacy and safety of the technique for potential clinical use.

Main Methods:

• A laser bowel welding technique was developed using a specialized LW clamp and two laser probes: Laser Bipolar Dissector (LBD) and Super Scalpel Dissector (SSD).
• The technique involved pinching the bowel with the LW clamp and using the laser probes through the clamp opening to cut and simultaneously seal the tissue.
• Optimal laser outputs were determined for different bowel sections (ileum, colon) in dogs and cats using both LBD and SSD probes.

Main Results:

• The study identified optimal laser power ranges for LBD (6-10 W) and SSD (6-10 W) in canine and feline ileum and colon.
• Complete sealing of the welded bowel site was histologically confirmed.
• The technique was effective using a diode laser output of approximately 8 W for 50-80 seconds.

Conclusions:

• Laser bowel welding using the LW clamp, LBD, or SSD probes is a feasible technique for dogs and cats.
• The method allows for simultaneous cutting and sealing of bowel tissue.
• This laser welding technique shows potential for application in clinical veterinary surgery.
