Articulating Enseal Versus Ligasure Energy Devices

This is an exploratory study to assess the ability of the raw-TLX (raw Task Load Index) ergonomic assessment tool to detect differences in surgeon workload when using commercially available advanced bipolar devices. It is anticipated that the raw-TLX version of the validated NASA-TLX ergonomic assessment tool will detect less surgeon effort required in the procedure when articulating ENSEAL is utilized. The Articulating ENSEAL device may also positively impact other variables such as blood loss, operative time and cost.

About this study

This study is a single-center, single-blinded, randomized control, pilot trial that will be conducted at the University of Louisville Hospital. It is designed to assess whether there are different surgical outcomes with regard to surgeon perception of ease of instrument use, operative time, estimated blood loss, cost and perioperative complication rates between the Ethicon Articulating Enseal versus the LigaSure for total laparoscopic hysterectomy. This will be assessed using the raw-TLX version of the validated NASA-TLX scale.

The study will be single-blinded in that the patient will not be informed of their group assignment; it is impossible to blind the surgeon using the devices.

Methods and Procedures:

Patients undergoing total laparoscopic hysterectomy will be recruited from our University of Louisville Health Care Outpatient Center (HCOC) outpatient office and will be consented for participation in the study during their preoperative office visit.

Patients will be randomized pre-operatively on their date of surgery to one of two groups:

Group 1: The articulating Enseal device will be used during the hysterectomy. Group 2: The Ligasure device will be used during the hysterectomy.

All cases will be videotaped for review of operative time and complications; this is standard procedure at our institution.

To evaluate our primary objective, i.e., the potential ergonomic and surgical advantages of an articulating tip in an energy device, the raw-TLX of the validated NASA-TLX scale will be completed by the primary surgeon at the end of each surgery.

Subjects will be seen for study follow-up during their routine post-operative visits at 2 weeks, 6 weeks and within 3 months after surgery in the event of a hospital admission for a surgery-related complication.

No compensation for participation will be offered to patients and no compensation for subject recruitment will be gained by investigators. This will be disclosed during the informed consent process.

Primary outcomes

  1. Raw Task Load Index (TLX) Score Assigned by Surgeons

    Time frame: 18 months

    The Official NASA Task Load Index (TLX) is a subjective workload assessment tool to allow users to perform subjective workload assessments on operator(s) working with various human-machine interface systems. By incorporating a multi-dimensional rating procedure, NASA TLX derives an overall workload score based on a weighted average of ratings on six subscales given below. The overall workload score ranges between 0 and 100 with 100 being the most demanding.

    Mental Demand Physical Demand Temporal Demand Performance Effort Frustration

Secondary outcomes

  1. Intra- and Post-operative Complications

    Time frame: 18 months

  2. Estimated Blood Loss

    Time frame: 18 months

  3. Need for Second Energy Device Intra-operatively

    Time frame: 18 months

  4. Time From Port Placement to Bilateral Uterine Artery Ligation and Hemostatsis.

    Time frame: During procedure

  5. Time Required to Complete Procedure

    Time frame: End of surgery up to 4 hours
