Summary

Internal hernias after Roux-en-Y gastric bypass (RYGB) can be reduced by using a BIO Mesh closure technique. This method significantly lowers the risk of internal hernias and open defects compared to traditional suturing or gluing methods.

Area of Science:

  • Bariatric Surgery
  • Surgical Techniques
  • Hernia Prevention

Background:

  • Internal hernias are a complication following Roux-en-Y gastric bypass (RYGB).
  • The method used to close surgical defects influences internal hernia risk.
  • Non-resorbable sutures reduce risk, but BIO Mesh may offer further improvement.

Purpose of the Study:

  • To evaluate the efficacy of a BIO Mesh closure technique in preventing internal hernias after RYGB.
  • To compare the outcomes of BIO Mesh closure with traditional suturing and glue methods for Peterson's space defects.

Main Methods:

  • Retrospective study of RYGB patients from 2014-2018 at two specialized bariatric surgery hospitals.
  • Entero-enterostomy (EE) closure used double-layered non-absorbable suture.

  • Peterson's space closure initially used glue, later transitioned to glue with BIO Mesh.

    • Main Results:

    • BIO Mesh closure of Peterson's space resulted in only 0.5% of patients with internal hernias or open defects, a significant reduction from 25% in the glued group.
    • The BIO Mesh technique was safe and effective, almost eliminating Peterson's space internal hernias.
    • A 1% rate of entero-enterostomy kinking was observed with the BIO Mesh technique due to adhesion formation.

    Conclusions:

    • Gluing intermesenteric spaces is not beneficial for preventing internal hernias.
    • BIO Mesh placement in Peterson's space is a safe and effective technique for inducing local adhesions and reducing internal hernias.
    • Further research via randomized controlled trials is recommended to compare BIO Mesh closure with double-layered non-absorbable sutures for optimal technique selection.
