Component Separation
A specialised surgical technique used to repair very large ventral hernias by releasing abdominal wall muscle layers to achieve tension-free midline closure.
What is Component Separation?
Component separation is an advanced reconstructive technique used for very large, complex ventral hernias where the midline cannot be closed by standard repair. The procedure involves releasing specific layers of the abdominal wall — most commonly the external oblique aponeurosis (anterior CS) or the transversus abdominis (posterior CS / TAR) — to allow the rectus muscles to advance medially and close the defect under minimal tension. Dr. Abhishek performs this at Lux Hospitals for patients with large hernias, loss of domain, or multiple failed previous repairs.
How the Procedure Works
Anaesthesia & Planning
General anaesthesia is administered; hernia defect size and abdominal wall anatomy are assessed.
Adhesiolysis
The hernia sac is opened, adhesions are carefully released, and abdominal contents are reduced.
Component Release
The external oblique aponeurosis (anterior CS) or transversus abdominis (posterior CS/TAR) is divided to mobilise the rectus muscles.
Mesh Reinforcement
A large mesh is placed in the retromuscular or preperitoneal plane with wide overlap for durable support.
Midline Closure
The midline is closed primarily over the mesh; skin is closed with drains placed to prevent seroma.
Outcomes
Who Needs This Treatment?
- →Enables closure of very large defects that cannot be bridged
- →Restores midline abdominal wall anatomy and function
- →Substantially reduces recurrence compared to bridged repairs
- →Allows treatment of loss-of-domain hernias safely
- →Improves abdominal core strength and quality of life
- →Performed with mesh reinforcement for durable long-term results
Component separation transformed how we approach giant hernias — patients who were once told they were inoperable now receive durable midline reconstruction. It is demanding surgery, but it gives them their abdominal wall and their life back.
