Comparison of lateral thermal spread using monopolar abd bipolar diathermy, the harmonic Scalpel and the Ligasure Presented to the 43rd World Congresso f Surgery of the International surgical Society, Adelaide, Austrália, September 2009

Purpose.The aim of this prospective randomized trial was to compare operative factors, postoperative outcomes, and surgical complications of neck dissection (ND) when using the harmonic scalpel (HS) versus conventional haemostasis (CH) (classic technique of tying and knots, resorbable ligature, and bipolar diathermy).Materials and methods.Sixty-one patients who underwent ND with primary head and neck cancer (HNSCC) resection were enrolled in this study and were randomized into two homogeneous groups: CH (conventional haemostasis with classic technique of tying and knots, resorbable ligature, and bipolar diathermy) and HS (haemostasis with harmonic scalpel). Outcomes of the study included operative time, intraoperative blood loss, drainage volume, postoperative pain, hospital stay, and incidence of intraoperative and postoperative complications.Results.The use of the HS reduced significantly the operating time, the intraoperative blood loss, the postoperative pain, and the volume of drainage. No significant difference was observed in mean hospital stay and perioperative, and postoperative complications.Conclusion.The HS is a reliable and safe tool for reducing intraoperative blood loss, operative time, volume of drainage and postoperative pain in patients undergoing ND for HNSCC. Multicenter randomized studies need to be done to confirm the advantages of this technique and to evaluate the cost-benefit ratio.

Background: Post-operative pain and bleeding are two major dilemmas associated with haemorrhoidectomy. Recent advances in energy sources have provided an alternative in reducing both the issues. This study was conducted with an aim to compare use of ultrasonic scalpel (Harmonic Scalpel) and bipolar diathermy in reducing post-operative pain and bleeding in Milligan-Morgan haemorrhoidectomy (MMH).Methods: Sixty patients with grade III and IV haemorrhoids underwent MMH, after being randomized into two groups, one half of them using Harmonic Scalpel and other group, using Bipolar diathermy scissors over a period of one year at Department of General Surgery at Sir Sayajirao Gaekwad (SSG) Hospital, Baroda. Operative data were recorded, and the patients were followed-up accordingly. Independent assessors were assigned to obtain blood loss, post-operative pain scores, analgesic requirements and other secondary outcomes.Results: Intra-operative bleeding, post-operative pain scores and duration of hospital stay were significantly lower with Harmonic scalpel as compared to bipolar diathermy scissors. However, there was no significant difference in both the groups with respect to first bowel movement and early or late complications.Conclusions: Harmonic scalpel can be used as an alternative to bipolar diathermy, in view of its good haemostatic capability, reduced post-operative pain and analgesic requirements.

The Mean

Introduction: The aim of this pilot retrospective study is to evaluate the complication rate in patients after axillary dissection comparing preparation with harmonic scalpel vs traditional ligation technique, and to analyse risk factors for complications occurrence. Methods: 144 patients with 148 axillary dissections operated in a single centre between January 2014 and 2019 were included into the study. Axillary dissection was performed using harmonic scalpel in 73 and absorbable ligations in 70 cases. Results: Seroma formation was observed in 41 patients (56.2%) in the harmonic scalpel group and in 21 patients (30.0%) in the ligations group (p=0.003). The mean period from the surgery to drain removal was 4.0 days in the harmonic scalpel group and 3.0 days in the ligations group (p<0.001). The mean amount of the drained fluid after mastectomy was 300.9 ml in the harmonic scalpel group and 168.7 ml in the ligations group (p=0.005); after breast conserving surgery, it was 241.9 ml and 107.4 ml, respectively (p =0.023). Conclusion: In comparison with traditional ligations with absorbable material, axillary dissection using harmonic scalpel significantly increases the risk of postoperative seroma formation, prolongs the time from the surgery to drain removal, and increases the amount of drained fluid.ut any suspicion of nodal involvement, hemithyroidectomy is considered to be a sufficient procedure or the method of choice, respectively.
