Introduction Only a few studies compare the efficacy of the harmonic scalpel and electrocautery in performing mastectomies, and these have mainly compared their intraoperative parameters. But the main concern with electrocautery is the incidence of flap necrosis and seroma formation. Therefore, this study was done to determine if the harmonic scalpel has any advantages over electrocautery in reducing postoperative flap necrosis and seroma formation in patients undergoing a modified radical mastectomy (MRM)...

Introduction: With the development of laparoscopic skills, the laparoscopic common bile duct exploration (LCBDE) and laparoscopic cholecystectomy (LC) has become the standard surgical procedure for choledocholithiasis. We usually use Hem-o-lok clips to control cystic duct and vessels, which is safe on most occasions and has few perioperative complications such as major bleeding, wound infection, bile leakage, and biliary and bowel injury. However, a rare complication of post-cholecystectomy clip migration (PCCM) increases year by year due to the advancement and development of LC, CBD exploration as well as the wide use of surgical ligation clips...

INTRODUCTION: A muscle flap can survive a pedicle injury under favourable conditions. In the reconstruction of compound limb injuries, the wound milieu is variable and may affect the rate and manner of neovascularisation. Our aim is to determine the effect of some key clinical variables on neovascularisation in muscle flaps in an animal model. METHODOLOGY: The pectoralis profundus was raised in 60 rats and covered with a skin graft. Fifteen rats were allocated to each of the following groups: separation of the flap from the skin inset (S), inflammation by inoculation with Staphylococcus aureus (I), flap elevation with harmonic scalpel (H) and preservation of the motor nerve (N) as well as compared to controls (C)...

Introduction Laparoscopic cholecystectomy (LC) is the most commonly done, minimally invasive surgical procedure. Routinely used electrocautery produces more smoke, which masks the operating field, thereby prolongs the surgery and posing an increased risk of gallbladder (GB) perforation. The titanium clips used for clipping the cystic artery and cystic duct have a risk of slippage, which may lead to bleeding, and an increased risk for bile leakage. In addition, it may act as a nidus for stone formation. Advanced energy sources, such as the harmonic scalpel, though expensive, may provide the advantage of shorter operating time by reducing smoke, bloodless dissection in the GB bed, lower risk of bleeding from the cystic artery due to secure vessel sealing, and avoiding the use of a larger number of titanium clips...

Energy devices can cause significant thermal damage to surrounding tissues causing unanticipated organ trauma. To evaluate the safety and feasibility of a novel electric device (DD1) for soft tissue dissection. Three series of measurements were performed in a pig model. First, macro- and microscopic tissue damage was compared between the DD1 and an electric scalpel (ES). Second, the time course of tissue temperature was measured for the DD1 and three other energy devices (ES, Harmonic and LigaSure). Third, the time required for mobilization of a peripheral artery of the intestine was compared between the DD1 and manual, non-energized forceps...
