초록

Steel scalpel과 $CO_2$ laser를 이용한 돼지 자궁 절개 시 창상 치유에 미치는 영향을 평가하고자 본 실험을 실시하였다. 다섯 마리의 Landrace - Yorkshire 혼혈 종 돼지를 이용하였고, 각각의 돼지에서 좌측 및 우측의 자궁에 대칭적으로 scalpel과 $CO_2$ laser를 이용하여 절개 하였다. 각각의 기구는 절개 속도, 절개의 용이성 및 출혈 정도를 평가 하였으며 수술 후 21일에 육안적인 유착 정도와 조직학적 검사를 실시하였다. Scalpel을 이용한 절개는 레이저를 이용한 절개보다 용이하였으나 두 군간의 유의성은 없었다. 레이저를 이용한 절개 시 출혈량은 적었으나 절개속도는 scalpel을 이용한 경우가 빨랐다. $CO_2$ laser 절개에서의 수술 후 자궁 유착은 scalpel 절개에서 보다 적게 발생하였다. 조직학적 검사에서 scalpel 절개의 경우 상피 조직과 자궁내막선의 재생이 완전히 이루어 졌으나 레이저를 이용한 경우 불완전한 재생 상태를 보였다. 비록 scalpel을 이용한 절개가 $CO_2$ laser를 이용한 경우 보다 조직 손상이 적었으며 사용하기 용이하였으나 출혈이 많은 단점이 있다. 반면 $CO_2$ laser를 이용한 절개의 경우 지혈 효과는 좋으나 창상 치유를 지연 시켰다.

This study compared the instrument performance and tissue healing of a steel scalpel with a $CO_2$ laser in an animal uterine surgery model. Five Landrace and Yorkshire mixed breed pigs were used. Two symmetrical incisions were made in the uterine of each pig. One incision was made on the left side of the uterine horn using a steel scalpel, while the other incision was performed on the right side using a $CO_2$ laser with an 8W output power. Each instrument was evaluated clinically for speed, ease of incision, and extent of bleeding. An ovariohysterectomy was performed at 21 days after the surgical procedure for a histological examination. The scalpel was an easier instrument to use in the confines of the uterine tissue, compared with the laser. However, there is no significant difference between the two groups. The amount of bleeding was less in the laser group but the time of the incisions was shorter with the scalpel. Postoperative uterus adhesion in the $CO_2$ laser incisions was lower than the scalpel incisions. Scalpel incisions showed complete restoration of the epithelium and endometrial gland. On the other hand, the laser incisions showed incomplete restoration of the epithelium and endometrial gland. Although the scalpel produced less damage to the uterine tissue and was easier to handle than the $CO_2$ laser, it did not provide hemostasis that was helpful for use on highly vascular tissue. The $CO_2$ laser provided good hemostasis but delayed wound healing.
