INTRODUCTION: Harmonic scalpel is being increasingly used in neck dissection as alternative to conventional electro-cautery for achieving haemostasis. Use of harmonic scalpel has been shown to significantly reduce intra operative blood loss and intra operative time in neck dissection. But how safe is it with regards to nerve injury (spinal accessory nerve and other nerves) during neck dissection. We intended to study the spinal accessory nerve injury during neck dissection by both harmonic scalpel and electro cautery technique and compared postoperative recovery of shoulder function after neck dissection...

The transoral division of the esophageal-diverticula septum with a linear stapler, with CO2 laser, or with harmonic scalpel under rigid endoscopy has revolutionized the surgical management of Zenker's diverticula. Nevertheless, the open approach still plays a role in select cases. Our goals are to illustrate the techniques and the results of our tailored approach to the surgical management of Zenker's diverticula in U.S. veterans.

INTRODUCTION AND OBJECTIVE: Appendectomy is one of the most common operations carried out by general surgeons. The recent introduction of the alternative energy-based devices in surgery and their use in the laparoscopic appendectomy shortened the duration of operations, but these devices are used generally for meso dissection. These devices did not receive wide acceptance among surgeons as there is not enough evidence confirming their use in appendicular lumen operations. Our objective in this study was to test the safety of three types of appendectomy...
