Coblator 와 전기소작기를 이용한 편도절제술의 결과 비교 : 전향적 무작위 대조 임상연구 = Coblator versus electrocautery tonsillectomy: A prospective randomized study comparing clinical outcomes

다국어 초록 (Multilingual Abstract)

Background and Objectives: Tonsillectomy is one of the most common procedures performed by ENT surgeons and multiple surgical techniques with instruments have been evolved. In electrosurgery, local temperatures of 400°C to 600°C results in heating of intracellular contents and subsequent vaporization of the cell. In contrast, coblation is achieved at temperatures between 60°C and 70°C with minimal collateral thermal tissue damage. This study was designed to compare intraoperative records and postoperative clinical outcomes following coblation and electrocautery tonsillectomy.
.
Materials & Methods: Forty-three patients with a history of chronic or recurrent tonsillitis were enrolled in this study. They were randomized into two groups. Seventeen patients were operated with Coblator and twenty-six patients with electrocautery, and all operations were done by one operator. Intraoperative cotton counts and operation time was checked, and post-operative pain score, otalgia, bleeding, wound recovery, starting day of normal diet were checked.

Results: Patients underwent coblation tonsillectomy reported significantly lesser pain on postoperative day(POD) 7. Mean operation time was statistically longer in coblation group then electrocautery group. However there was no other statistically significant difference in other intraoperative records and postoperative clinical outcomes between two groups.

Conclusion: These results indicate that patients underwent coblation tonsillectomy reported lesser pain on POD 7. However mean operation time was longer in coblation group. This is a pilot study and further study with larger numbers of patients is on going.
