✦ Synopsis

Abstract

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.
