Fifteen mongrel dogs underwent a left lateral non-anatomical partial hepatectomy using a carbon dioxide laser, diathermy or a surgical scalpel. An original prototype of a compact hand-held laser was used and its effects were compared with those of the other two instruments. An improved dry cat surface was achieved by placing a rubber snare proximal to the planned incision. While no significant differences in the blood loss or in the operating time were found among the experimental groups, the laser beam sealed vessels of up to about 6 mm in diameter without any complementary suture ligatures, which were needed in the other groups. Histological studies revealed less tissue trauma in the sections performed by the laser and only slight secondary inflammatory reaction.
15只杂种犬接受了使用二氧化碳激光、透热疗法或手术刀进行的左侧非解剖性部分肝切除术。使用了一种紧凑型手持激光的原始原型,并将其效果与其他两种器械的效果进行了比较。通过在计划切口近端放置橡胶圈套器,实现了改良的干燥手术表面。虽然各实验组之间在失血量或手术时间上没有发现显著差异,但激光束可封闭直径达约6毫米的血管,无需其他组所需的任何补充缝合结扎。组织学研究显示,激光操作的切片中组织损伤较小,仅有轻微的继发性炎症反应。
