LigaSure Small Jaw® Versus Conventional Neck Dissection in Head and Neck Cancer Patients

August 24, 2016 updated by: Shih-An Liu, Taichung Veterans General Hospital

A Prospective Randomized Study of LigaSure Small Jaw® Versus Conventional Neck Dissection in Head and Neck Cancer Patients

The aim of this prospective randomized study was to investigate if the LigaSure vessel sealing system can reduce the operation duration and the postoperative drainage amount in patients undergoing neck dissection.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

We compared the differences in perioperative and postoperative variables between LigaSure Small Jaw®-assisted and conventional neck dissection in head and neck cancer patients.

Patients who were scheduled to undergo neck dissection due to head and neck cancer were eligible for this study. After receiving a detailed explanation, all patients signed an informed consent form before randomization. The study group were treated using the LigaSure vessel sealing system (Small Jaw®; Covidien, Colorado, USA) for dissection and hemostasis throughout the whole procedures during neck dissection. Relevant data included tumor-related variables, perioperative parameters, postoperative drainage status, postoperative subjective pain, and analgesic consumption amount were recorded and analyzed.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Active Comparator: Ligusure assisted neck dissection

The study group patients were treated using the LigaSure vessel sealing system (Small Jaw® with ForceTriad®; Covidien, Colorado, USA) for dissection and hemostasis throughout the whole procedures during neck dissection.

Participants were asked to take a Voren enteric-microencapsulated (Diclofenac 50 mg/capsule) capsule 3 times a day for pain relief postoperatively. An additional capsule before sleep was allowed if persistent pain was told by the patient. When intolerable pain was complained in spite of oral analgesic, pethidine (meperidine 50 mg/ampule) injection was prescribed every 6 hours.
Procedure: Neck dissection
The Small Jaw® handpiece (Small Jaw® with ForceTriad®; Covidien, Colorado, USA) was not only used as a dissection forceps but also served as a ligation device.
Other Names:
  • Ligasure vessel sealing system
Other: Conventional neck dissection

The control group patients were treated using conventional cold instrument dissection, monopolar electrocautery hemostasis, and suture ligation during neck dissection.

Participants were asked to take a Voren enteric-microencapsulated (Diclofenac 50 mg/capsule) capsule 3 times a day for pain relief postoperatively. An additional capsule before sleep was allowed if persistent pain was told by the patient.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Opreation Duration
Time Frame: 1 day
The duration from incision of cervial skin till the completion of lymph node dissection
1 day

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Intraoperative Blood Loss
Time Frame: 1 day
Intraoperative blood loss was estimated by the sum of the volume in the suction bottle and the increased weight of wet gauzes containing blood after neck dissection.
1 day
Postoperative Drainage Amount
Time Frame: 2 weeks
The amount of drainage from closed system drainage tube
2 weeks
Postoperative Subjective Pain Status
Time Frame: 2 weeks
Visual analogue scale of subjective pain status after operation
2 weeks
Postoperative Oral Analgesic Consumption
Time Frame: 2 weeks
The amount of analgesic consumption via oral ingestion after operation
2 weeks
Postoperative Injected Analgesic Amount
Time Frame: 2 weeks
The amount of injected form analgesic used (Meperidine 50 mg/ampule)
2 weeks
