The Sponsor terminated the study.

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.

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
• Patients unable to tolerate general anesthesia
• Patients who are pregnant
• Patients unwilling or unable to provide informed consent
• Patients who have undergone significant upper GI surgery leading to adhesion formation, as determined by the Principal Investigator.

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.
