Prospective Case-Series of Ligasure Advance Pistol Grip and LigaSure Blunt Tip

January 16, 2024 updated by: Duke University

Prospective Case-Series of LigaSure Advance Pistol Grip and LigaSure Blunt Tip in Gastric Procedures

The study is primarily to evaluate the safety and efficacy of the LigaSure Advance™ Pistol Grip and LigaSure™ Blunt Tip using the Force Triad™ Energy Platform during Roux-en-Y and gastric reduction procedures (sleeve gastrectomy or placation), respectively. Also, Economic value of using LigaSure in gastric surgeries will be appraised.

In this prospective case series, 60 patients previously scheduled to undergo a Roux-en-Y or gastric reduction procedure (sleeve gastrectomy or placation) will have hemostasis controlled with LigaSure Advance ™ Pistol Grip or LigaSure™ Blunt Tip, respectively. All subjects undergoing Roux-en-Y or gastric reduction procedures (sleeve gastrectomy or placation) procedure at Durham Regional Hospital will be recruited.

Data Analysis will be performed using the data collected in the software program titled MetaBar at Duke University Medical Center. Categorical variables will be summarized as proportions for each category; continuous measures will be summarized by mean and standard deviation or median and range as appropriated for the data distribution. Procedure-related risks are those typically associated with gastric procedures and general anesthesia including intra-operative bleeding, infection, and injury to surrounding organs and structures. Device related risks include those normally associated with the use of electrosurgery including intra-operative bleeding, unintended tissue burns, electrical shock, and electrical stimulation of muscles and nerves.

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

18 years and older (Adult, Older Adult)

Sampling Method

Non-Probability Sample

Study Population

This study will include 60 patients previously scheduled to undergo a Roux-en-Y or gastric reduction precodures (sleeve gastrectomy or placation) using the LigaSure Advance Pistol Grip or LigaSure Blunt Tip, repectively. The pricipal investigator will be responsible for patient selection.

Description

Inclusion Criteria:

  • Patients 18 years of age or older
  • Patients who will undergo a Roux-en-Y or gastric reduction procedures (sleeve gastrectomy or placation)
  • Patients with a BMI between 40-60

Exclusion Criteria:

  • Patients under 18 years of age
  • Patients participating in other competing research protocol(s)
  • Patients for whom electrosurgery is contraindicated

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
LigaSure Device
In this prospective observational study, 60 patients scheduled to undergo a Roux-en-Y or gastric reduction procedure (sleeve gastrectomy or plication) will have hemostasis controlled with LigaSure Advance ™ Pistol Grip or LigaSure™ Blunt Tip, respectively. Both devices are regularly used at Duke in the Bariatric Surgery division. The surgeon will select which device is used. There will be no randomization. The device decision tree will be based upon the procedure. Cases that require enterotomy will utilize the AdvanceTM pistol grip. Cases which don't need enterotomy will utilize the 5 Blunt Tip. The LigaSure AdvanceTM pistol grip and LigaSureTM Blunt Tip are used exclusively with the Force TriadTM Energy platform. There is no simultaneous use.

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
Safety and Efficacy of the LigaSure Advance Pistol Grip and LigaSure Blunt Tip using the Force Triad Energy Platform during Roux-en-Y and gastric reduction procedures.
Time Frame: 1 month
Primary study variables include patient demographic information (age, pre- and post-operative BMI, gender, and presence of obesity associated co-morbid disease conditions such as hypertension, diabetes, sleep apnea, obesity hypoventilation, heart failure, prior blood clots, etc.), procedure time, American Society of Anesthesiologists (ASA) score, operative blood loss,length of hospital stay, and any complications noted up to one month post-operative.
1 month

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
Economic value of using LigaSure in gastric surgeries
Time Frame: 1 month
These variables include the costs of the instrument, duration and costs of anesthesia, postoperative analgesic use, and hospital day rate costs to study the economic impact of different hemostatic devices and observe trends towards cost differences. Outcomes such as perceived ergonomics, multi-functionality, and access to organs will be collected.
