BACKGROUND: In laparoscopic cholecystectomy dissection can be with monopolar electrocautery or with ultrasonic shears, and can start at the triangle of Calot or at the fundus of the gallbladder. METHODS: Thirty-seven patients undergoing laparoscopic cholecystectomy were randomized to electrocautery dissection from the triangle of Calot and 43 to fundus-first dissection with ultrasonic shears. All procedures were strictly standardized, and patients and their postoperative carers were blinded to the operation performed. RESULTS: Ultrasonic fundus-first dissection was associated with a shorter duration of operation (mean 46 versus 61 min), fewer overnight hospital stays (two versus eight), lower pain scores 4 and 24 h after surgery, less nausea at 2, 4 and 24 h, and a shorter period of sick leave (mean 5.5 versus 9.3 days) compared with electrocautery from the triangle of Calot. CONCLUSION: Ultrasonic fundus-first dissection during laparoscopic cholecystectomy was quicker and associated with less nausea and pain than electrocautery dissection from the triangle of Calot.
