About this study
Official title: 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.
Read the 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Intraoperative Endoscopic Staple Line Bleeding Score
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.
Measured: Within surgery, after the last stapler firing
Intraoperative Laparoscopic Staple Line Bleeding Score
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.
Measured: Within surgery, images captured 10 seconds after the last stapler firing
Secondary outcomes (4)
Number of Participants With Postoperative Leakage Requiring Intervention
Number of participants with postoperative leakage requiring intervention
Measured: Within 30-day post-operative period
Number of Participants With Intraoperative or Postoperative Blood Transfusion
Number of participants with intraoperative or postoperative blood transfusion
Measured: Within 72 hours of surgery start time
Number of Participants With Reported Device-related Adverse Events
Number of participants with reported device-related adverse events
Measured: Within 30-day post-operative period
Number of Participants With Product Malfunction
Number of participants with product malfunction. Product malfunction means any occurrence during the surgery where the stapler does not perform as intended.
Measured: Within surgery

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Intraoperative Endoscopic Staple Line Bleeding Score (time frame: Within surgery, after the last stapler firing). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
