Brief Summary:

This study is conducted to compare performance characteristics of staple lines resecting the stomach in excised human gastric tissue with existing Echelon Flex Powered Plus GST System (Ethicon, size: 60mm, "Echelon") stapler and the Titan SGS (Standard Bariatrics, "Titan").

The Study is a single center clinical trial, randomized (1:1, Arm A - Ethicon Echelon 60 application, Arm B - Standard Bariatrics Titan SGS application) which utilizes the excised stomach tissue from up to 75 adults undergoing laparoscopic sleeve gastrectomy (LSG). This study will be conducted in the USA.


Condition or disease Intervention/treatment
Gastric Resection Device: gastric tissue resection

Layout table for study information
Study Type : Observational
Actual Enrollment : 36 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Gastric Tissue Stapler Comparison Study
Actual Study Start Date : July 15, 2019
Actual Primary Completion Date : October 30, 2019
Actual Study Completion Date : October 30, 2019

Group/Cohort Intervention/treatment
Arm A - Echelon Stapler
Excised gastric tissue specimens will be resected with the Echelon Stapler (Ethicon, size: 60mm, "Echelon") and evaluated for burst pressure and staple malformation
Device: gastric tissue resection
human stomach specimens will be resected with the surgical staplers for pressure testing and staple malformation assessment

Arm B - Titan Stapler
Excised gastric tissue specimens will be resected with the Titan SGS Stapler (Standard Bariatrics, "Titan") and evaluated for burst pressure and staple malformation
Device: gastric tissue resection
human stomach specimens will be resected with the surgical staplers for pressure testing and staple malformation assessment




Primary Outcome Measures :
  1. Pressure Evaluation [ Time Frame: immediately post operative ]
    Burst pressure will be assessed in the specimen with one staple line (i.e. the test staple line) with a pressure volume curve recorded.

  2. Staple Malformation [ Time Frame: through study completion, anticipate within 2 months ]
    Staple line specimen will be sent to an independent laboratory for imaging. Percentage of malformed staples in test staple line will be recorded by an independent assessor.
