研究目的
To develop a new bowel welding method using a diode laser for dogs and cats, aiming to apply it in clinical cases for conditions like megacolon in cats and severe bowel obstruction in toy-breed dogs.
研究成果
The study confirmed that diode laser bowel welding in dogs and cats is feasible using the LW clamp and contact probes at approximately 8 W output for 50-80 seconds of irradiation. Clinical applications showed no severe postoperative complications, with all patients recovering favorably, suggesting it as a safe method for bowel anastomosis in small animals with relatively narrow intestinal diameters.
研究不足
The study was limited to experimental and clinical applications in dogs and cats, focusing on specific conditions like megacolon and severe bowel obstruction. The technique's applicability to other species or conditions was not explored.
1：Experimental Design and Method Selection:
The study devised a new bowel welding method using a diode laser and developed a special intestinal clamp named laser welding intestinal clamp (LW clamp).
2：Sample Selection and Data Sources:
Used intestines from 16 dogs and 16 cats post-mortem.
3：List of Experimental Equipment and Materials:
Utilized an 810 nm wavelength semiconductor laser device (PDL-Pulse Diode Laser), two types of direct contact probes (LBD and SSD), and a specially designed LW clamp.
4：Experimental Procedures and Operational Workflow:
The intestines were held together with the LW clamp, and laser irradiation was performed through the clamp's window using the probes. The welding time varied from 1 to 4 minutes.
5：Data Analysis Methods:
The bursting pressure (BP) was measured as an indicator of the physical strength of the welded site.
