NCT02080546

Brief Summary

Purpose of this randomized control study is to determine if the mode of electrothermal colpotomy incision affects (1) the degree of thermal injury at the time of laparoscopic hysterectomy or (2) the incidence of clinical surrogates of compromised vaginal cuff healing. Women already scheduled for TLH will be randomized to colpotomy incision with the V mode or standard cut/coag form of electrothermal energy. Prevalence of vaginal cuff injury will be calculated, and cross tabulation tables will be used to examine the association fo dehiscence with proposed risk factors in the retrospective part of the study. In the randomized controlled trial, depth of thermal injury will be compared between the two groups, and a chi-square test will be used to test for a difference in clinical outcomes between the two groups. There is little risk associated with this study above the normal surgical risks; however, the V mode has not been previously been studied for its use in making a colpotomy incision. Loss of confidentiality is a risk of the study, but all samples will be de-identified and given a unique study number, and only individuals directly involved in the study will be given access to the study information.

Outcome Measures

Primary Outcomes (1)

  • Degree of Thermal Injury at the Time of Laparoscopic Hysterectomy

    distance in millimeters over which thermal tissue injury extends (henceforth referred to as "injury").

    up to 36 months

Secondary Outcomes (1)

  • Incidence of Clinical Surrogates of Compromised Vaginal Cuff Healing

    4 weeks, 3 months, and 6 months after hysterectomy for a post-operative check and pelvic examination

Study Arms (2)

Cut/Coag

ACTIVE COMPARATOR
Procedure: Cut-CoagDevice: Valleylab G3000 Electrosurgical Device

V-mode

EXPERIMENTAL
Procedure: V-modeDevice: Valleylab G3000 Electrosurgical Device

Interventions

Cut-CoagPROCEDURE

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.

Also known as: Valleylab G3000 Electrosurgical Device
Cut/Coag
V-modePROCEDURE

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.
