Endostapler Sleeve Gastrectomy Study

September 27, 2021 updated by: Lexington Medical Inc.

A Randomized Study Comparing Endostaplers in Sleeve Gastrectomy

The goal of this prospective, post-market study is to measure AEON™ Endostapler performance for laparoscopic sleeve gastrectomy surgery versus the Endo GIA™ Reloads with Tri-Staple™ Technology from Medtronic.

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

Stapler performance will be evaluated primarily by incidence and degree of staple line bleeding from endoscopic images, evaluated by a blinded third-party. The study will include 60 total consecutive cases of individuals undergoing a planned laparoscopic sleeve gastrectomy (LSG). The LSG procedure will be performed according to institutional standard-of-care and all subjects will undergo standard preoperative evaluation as well as post-operative care.

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.

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
Intraoperative Endoscopic Staple Line Bleeding Score
Time Frame: Within surgery, after the last stapler firing
Intraoperative staple line bleeding score from endoscopic images as measured by the provided Bleeding Severity Scale (1 = No bleeding; 2 = Minimal bleeding; 3= Moderate bleeding; 4 = Excessive bleeding; 5 = Profuse bleeding). A lower value represents a better outcome.
Within surgery, after the last stapler firing
Intraoperative Laparoscopic Staple Line Bleeding Score
Time Frame: Within surgery, images captured 10 seconds after the last stapler firing
Intraoperative staple line bleeding score from laparoscopic images as measured by the provided Bleeding Severity Scale (1 = No bleeding; 2 = Minimal bleeding; 3= Moderate bleeding; 4 = Excessive bleeding; 5 = Profuse bleeding). A lower value represents a better outcome.
Within surgery, images captured 10 seconds after the last stapler firing

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
Number of Participants With Postoperative Leakage Requiring Intervention
Time Frame: Within 30-day post-operative period
Number of participants with postoperative leakage requiring intervention
Within 30-day post-operative period
Number of Participants With Intraoperative or Postoperative Blood Transfusion
Time Frame: Within 72 hours of surgery start time
Number of participants with intraoperative or postoperative blood transfusion
Within 72 hours of surgery start time
Number of Participants With Reported Device-related Adverse Events
Time Frame: Within 30-day post-operative period
Number of participants with reported device-related adverse events
Within 30-day post-operative period
Number of Participants With Product Malfunction
Time Frame: Within surgery
Number of participants with product malfunction. Product malfunction means any occurrence during the surgery where the stapler does not perform as intended.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
