Effect of Microsurgery Training Program for Hepatic Artery Reconstruction in Liver Transplantation
(배경 및 목적) 생체부분간이식 시 간동맥 재건에 미세수술수기가 도입되면서 간동맥 합병증이 3.8%까지 줄었다는 보고들이 있다. 그러나 대부분의 센터에서 간이식 프로그램의 시작 단계에서 성형외과나 정형외과 등 일반외과 이외의 미세수술담당의의 도움을 받게 되는 것이 보편적인 경향이다. 본원에서도 성인생체간이식을 시작한 2005 년 2 월부터 2008 년 6 월까지 성형외과 미세수술의의 도움을 받아 간동맥재건을 하였고, 점차 간이식 예가 증가함에 따라 간외과 자체 미세수술의의 필요성이 대두되어 미세수술에 경험이 없는 일반외과의를 …

Microsurgical techniques in regenerative periodontal therapy
Microsurgery and minimally invasive surgery should be considered a true reality in periodontal regenerative surgery. Several clinical trials have shown their efficacy and predictability in the treatment of intrabony defects. In 1992 microsurgery was introduced to the field of periodontics. The main …
