Esculapio J Services Inst Med Sci Jan ;15(1):7-9.

Objectives: To compare the results of ultrasonic dissector or conventional-surgery in terms of shorter operative time, hospital study and average drain output and to evaluate the incidence of postoperative complications. Material and Methods: A prospective randomized trial was conducted at surgical Unit-II of Services Hospital, Lahore. Duration of study was two years. After approval from ethical committee 100 patients with thyroid disease were included. These patients were divided in Ultrasonic Dissector (UD) group & Conventional Surgery (CS) group (50 each). In UD group patients were under went thyroidectomy with use of harmonic scalpel while in CS group patients were operated with suture ligations of vessels along with use of monopolar or bipolar cautery. All the data was collected on self-designed proforma & SPSS 20 version was used for data analysis. Results: The mean age of patients was 30+-17 with dominant female gender. In UD group the mean operative time was 50.4 +- 7.41 minutes which was significantly lower than in CS group which was 88.6+-3.89 min. Drain output was 23.9+-15 ml & 33.7+-30.2 ml in UD and CS group respectively with p- value of 0.024. P-Value was significant (<0.000) for hospital stay. Most common complication was parathyroid injury (12% cases in UD group & 16.0% in CS group). Hematoma & seroma formation was noted in 12% in each group. Conclusion: We concluded that the use of Ultrasonic Dissector significantly decreases operative time compare to Conventional Surgery techniques. It is also safer in terms of reducing the incidence of postoperative complications.
