돼지에서 CO2 laser와 외과용 수술도를 이용한 위 절개 시 창상 치유 평가 = Comparative Study of Wound Healing in Porcine Stomach with CO2 Laser and Scalpel Incisions

다국어 초록 (Multilingual Abstract)

We compared wound healing with CO2 laser incision and scalpel incision by measuring the extent of bleeding, the ease of incision, time, degrees of adhesion and histological observation in pig's stomach. Eight healthy pigs were used. Two symmetrical incisions were made in ventral aspect of the stomach between the greater curvature and lesser curvature were made with scalpel and 2 mm spot diameter CO2 laser (8W, continuous wave) in eight pigs.
And then each wound was closed with absorbable suture in a two-layer inverting seromuscular pattern. At 7 and 14days after initial wounding, each wound was taken for histological observation. On surgery, the extent of bleeding,the ease of incision and incision time showed significant differences between the two groups. The CO2 laser provided better hemostasis (p < 0.01) and smaller postoperative adhesion compared with the scalpel. However, the scalpel produced faster speed of incision and was easier to handle than the CO2 laser group (p < 0.01). There was no considerable difference between the two groups in histological observation.
