Nd:YAG激光对狗胰切除的实验研究

EXPERIMENTAL STUDY ON PARTIAL DISTAL PANCREATECTOMY WITH Nd : YAG LASER IN DOGS

本文报告了Nd:YAG激光对狗胰部分切除的实验研究。结果证实:激光组(接触式、非接触式)与普通手术刀切胰比较,其止血效果好,以接触式激光刀最佳。术后定期复查血糖和淀粉酶未发现有显著差异。组织学检查提示,激光胰切缘主要为热损伤,且局限于距切缘0.5cm范围。激光切胰后即刻及术后定期做胰管造影表明,切缘胰管封闭良好。

This study reported that partial distal pancreatectomy was performed in dogs with Nd: YAG laser. Its results was compared with that obtained with use of scalpel and sutures. The cut edge of the pancreatic tail was coagulated effectively until hemostasis was achieved. The Nd:YAG laser can cut pancreatic tail quickly and effectively. Postoperative normal amylasemia and no hypoglycemia appeared in all the animals. Histological study of laser groups showed thermal injury at the cut section with damage to the nearby parenchyma. Pancreatography showed a sealed pancreatic duct in laser groups although no duct ligation was performed.
