Vaginal cuff thermal injury by mode of colpotomy at total laparoscopic hysterectomy: a randomized clinical trial.

Study Objective: To evaluate if the use of Valleylab mode ("V mode") (Covidien, Mansfield, MA) electrothermal energy for colpotomy during total laparoscopic hysterectomy (LH) results in a smaller margin of thermal injury to the upper vagina compared with traditional cut/coagulate (cut/coag) electrothermal energy.

Design: Prospective randomized clinical trial (Canadian Task Force classification I).

Setting: University medical center.
