| Abstract: |
| Objective The aim of this study was to analyze and evaluate 1.32-μm and 1.06-μm neodymium-doped
yttrium aluminum garnet (Nd:YAG) lasers for use in liver and gastroepiploic vessel vaporization and
coagulation.
Methods The effects of 1.32-μm and 1.06-μm Nd:YAG lasers were compared for gastroepiploic vessel
hemostasis in porcine liver.
Results The results were observed and measured under the same parameters and dose conditions.
The 1.32-μm laser showed greater vaporization width and depth than the 1.06-μm laser. Both lasers
controlled active bleeding. The coagulation band with the 1.32-μm laser was thinner than with the 1.06-
μm laser, at nearly 3 mm. After cutting of 1- and 2-mm porcine vessels, no grossly visible bleeding was
apparent. Intravascular thrombus was visible under the microscope. The length of vessel thrombosis in the
experimental group was 2 mm and the diameter was 2 mm; the control group exhibited thrombi as 2.3–4.9
mm in length. Thrombosis completely blocked the blood vessels.
Conclusion The 1.32-μm laser had greater vaporization capability than the 1.06-μm laser and achieved
hemostasis requirements for vessels less than 2 mm in diameter. |
