The purpose of this study was to perform an overall evaluation and comparison of the success rate of modified radical mastectomy by harmonic scalpel and monopolar electrocauter The prospective study included all of the patients that were planned for and mastectiomized because of breast carcinoma during July 1st 2008 until December 21st 2008 at the Department of Surgery and Urology, University H...

PURPOSE In our study, the effects of harmonic scalpel, scalpel, and monopolar electrocautery usage on the health and healing of colon anastomosis after resection was investigated. METHODS In this study, 120 female albino Wistar rats were divided into 3 groups each containing 40 rats. Group A, resection with scalpel; group B, resection with monopolar electrocautery; group C, resection with har...

Tongue surgery is almost always complicated by intraoperative bleeding. Its rich blood supply especially from the lingual vessels makes the operative field bloody. Electrocautery has been widely used to replace cold scissors in order to achieve better hemostasis. The use of ultrasonic harmonic scalpel for glossectomy is still new in this country. We report a case of partial glossectomy using th...

EDUCATIONAL OBJECTIVE At the conclusion of this presentation, the participants should be able to describe the tissue effects of steel scalpel, monopolar electrosurgery, and ultrasonic scalpel glossectomy with respect to histopathologic margin assessment in a rat model. OBJECTIVES Histopathologic margin assessment is important in guiding treatment and determining prognosis for squamous cell ca...

Any laparoscopic surgery demands appropriate surgical instruments. Most surgeons nowadays have adapted to this different form of surgery and have particular preferences for certain types of graspers, dissectors and cutting instruments. The general component of laparoscopic instrument includes the hand grip, shaft, jaw and the tip. The harmonic scalpel is a surgical instrument used to simultaneo...

Background: Energy sources have been an important part of surgery in achieving hemostasis and bloodless field to operate. Nowadays the most recent and commonly used are the bipolar vessel sealing system (LigaSure) and the harmonic scalpel (HS). Purpose: To do a comparative review between the LigaSure vessel sealing system and harmonic scalpel to make surgery faster, safer and better. Materials ...

OBJECTIVE To evaluate use of the Harmonic Scalpel (Ethicon Endo-Surgery Inc., Cincinnati, OH) for performing laparoscopic bilateral ovariectomy in standing horses. STUDY DESIGN Experimental study. ANIMALS Eight mares aged 2-20 years and weighing 410-540 kg. METHODS Standing laparoscopic bilateral ovariectomy was performed in 8 mares with normal reproductive tract anatomy. The Harmonic Sca...

Haemostasis is crucial in thyroid surgery to avoid intraoperative and postoperative complications. In the present study, we evaluated the efficiency and the safety of Harmonic scalpel when compared to conventional suture ligation in open total thyroidectomy. We enrolled 265 patients who underwent total thyroidectomy for multinodular disease since October 2011 up to October 2013. They were rando...

Surgeons conventionally use electrocautery dissection and surgical clip appliers to harvest free flaps. The ultrasonic Harmonic Scalpel is a new surgical instrument that provides high-quality dissection and hemostasis and minimizes tissue injury. The aim of this study was to evaluate the effectiveness and advantages of the ultrasonic Harmonic Scalpel compared to conventional surgical instrument...

Conflicts of interest: none. aBstRact objectives: To analyze the operative time, length of hospitalization and cost, as well as the bleeding and pain observed during the postoperative period, of thyroidectomy procedures using vessel sealing, harmonic scalpel or the conventional technique. methods: Retrospective analysis of thyroidectomies performed between 2007 and 2010 using either the convent...
