About this study
Official title: Comparative Study Between Onlay and Sublay Mesh in Treatment of Ventral Hernia
Hernia is defined as aprotrusion of viscus or part of viscus usually within a peritonial sac through a defect in the abdominal wall.
Ventral abdomenal hernias include all the hernias occuring through the anterior abdominal wall excluding groin hernias ( incisinal hernia, epigastric hernias, paraumbilical hernias, umbilical and lumbar hernias)
Read the detailed description
Ventral hernia can be categorized according to their characteristic into reducible, irreducible or incarcerated , strangulated and recurrant ventral hernia.
The cause of a primary ventral hernia ia s far from completely understood, but it is undoubtedly multifactorial. familial prediposing play a role with increasing evidance of connective tissue disorders, they are considered as a leading cause of abdominal surgery and account for 2-10% of all abdomenal wall hernias .
Clinical data show that 52% of incisional hernias occur within 6 months postoperative as a result of excessive tension and inadeqate healing of aprevious incision.
The history of prothetic repair in abdominal wall hernias began in 1844 within the use of silver wire coils placed in the floor of groin to induce an inflammatory fibrosis . meny prosthetic material have been tried in hernia repair, but the two most common in current use are polypropylene mesh and expanded polytetrafluoroethylene.
The repair of ventral hernia varies from primary closure, primary closure with an onlay mesh reinforcement, sublay mesh placement, and intraperitonial mesh placement. Primary closure techniques are usually performed for smal fascial defects less than 5 cm in the greaters diameter
An onlay , usually of polyproptlene mesh is sutured to the anterior rectus sheeth after the fascial defect has been closed primary, thes type of repair has the potential advantage of keeping the mesh separeted from the abdomenal content by full abdominal muscle fascial wall thikness.
The sublay (retrorectus) placement of mesh, became popular in 1990, the recurence rates with this repair have been stated to be less than 10%.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Onlay MeshProcedure or surgery
Also called Sublay Mesh
to compare between two techniques of mesh placement in uncomplicated ventral hernias, onlay (mesh on external oblique) versus sublay (mesh in the retromuscular space).
| Study group | Role | What they receive |
|---|---|---|
| Group I | Active comparator | About 15 patients subjected to ventral hernia of onlay mesh procedure (mesh on external oblique muscle) Receives: Procedure: Onlay Mesh |
| Group II | Active comparator | About 15 patients subjected to ventral hernia of sublay mesh procedure (mesh in the retromuscular space) Receives: Procedure: Onlay Mesh |
What is being measured
The primary outcome is the main question the study is designed to answer.
Post operative Pain
Assessment of post operative Pain by VAS scale
Measured: 4 hours post operative
