An observational study in Incisional Hernia and Aortic Aneurysm, sponsored by Hôpital Fribourgeois. Recruiting at 1 site in Switzerland. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-06-03.
Sponsored by Hôpital Fribourgeois · Observational
The goal of this retrospective observational study is to evaluate whether prophylactic mesh reinforcement during abdominal wall closure can prevent incisional hernias (IH) in patients undergoing open abdominal aortic aneurysm (AAA) repair. The main questions it aims to answer are:

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Patients who underwent open abdominal aortic aneurysm (AAA) repair with prophylactic retromuscular mesh reinforcement at the Fribourg Cantonal Hospital between 2019 and 2024.
Procedure: Prophylactic retromuscular mesh reinforcement
Prophylactic retromuscular mesh placement involves reinforcing the abdominal wall during closure after open abdominal aortic aneurysm (AAA) repair to prevent incisional hernias. This technique creates a retro-muscular space by carefully dissecting the rectus abdominis muscles from the posterior rectus sheath. A self-gripping polyester mesh or composite mesh is placed in this space, extending 4 cm beyond the midline on each side, ensuring tension-free coverage. The mesh is secured at key points, and the rectus sheaths are closed with continuous sutures. This approach leverages the anatomical integrity of the abdominal wall to reduce hernia risk without increasing postoperative complications.
