Recruitment status

COMPLETED

Study phase

NA

Target enrollment

120 participants

Primary outcome timeframe

up to 36 months

Participant Flow

19 subjects either withdrew or were excluded from the study. Thermal injury could not be assessed in 18 specimens because of sampling error.

Measure
Cut/Coag
Cut-Coag: Incision using electrothermal cautery, with an attempt made to use the "cut" (continuous low-voltage, high-current) for colpotomy incision following the initial scoring of the cervico-vaginal tissue on the "coag" (pulsed high-voltage, low-current) mode. Valleylab G3000 Electrosurgical Device: Use of surgical device Valleylab G3000 Electrosurgical Device
V-mode
V-mode: Incision using electrothermal cautery in the "V mode". The V mode combines real-time tissue sensing technology with the cut and coag waveforms to reduce the amount of thermal spread to the tissue without sacrificing hemostasis during monopolar electrothermal procedures.

PRIMARY outcome

Timeframe: up to 36 months

Population: 49 participants were included in the cut/coag arm and 52 participants in the V mode arm. Thermal injury was assessed at the anterior margin in 91 specimens and at the posterior margin in 93 specimens.
