A recurrent hernia is a hernia that returns at the site of a prior repair. Reported recurrence rates after primary repair range from roughly 1% to over 15%, depending on hernia type, technique, mesh, and surgeon volume. Recurrent repair is a different operation than primary repair — and the choice of approach has long-term consequences.
Why hernias recur
- Inadequate mesh size or overlap at the original repair
- Mesh placed in the wrong anatomic plane
- Tissue-only repair where mesh would have been appropriate
- Technical issues with fixation or defect closure
- Patient factors: smoking, obesity, diabetes, chronic cough, connective tissue disorders
- Postoperative wound infection
Why the second repair is harder
Prior surgery distorts anatomy. Scar tissue obscures normal tissue planes, nerves are displaced or encased, and prior mesh may be incorporated into surrounding structures. The risk of nerve injury, vascular injury, and bowel injury rises in any reoperative field. Recurrent hernia repair is appropriately considered specialist surgery.
Choosing the approach based on the first operation
Recurrence after open anterior inguinal repair
When a hernia recurs after an open anterior approach (Lichtenstein, plug-and-patch), most specialists prefer a posterior minimally invasive approach (laparoscopic TEP/TAPP or robotic). This avoids dissecting through the previous scar and approaches the defect from healthy tissue.
Recurrence after laparoscopic or robotic inguinal repair
When the original repair was posterior, an open anterior approach often makes the most sense for the same reason — fresh tissue planes.
Recurrent ventral or incisional hernia
Recurrent ventral and incisional hernias frequently benefit from robotic or open retrorectus repair (eTEP, TAR — transversus abdominis release) with wide mesh overlap. These are complex operations that should be performed by surgeons doing them regularly.
Mesh considerations in recurrent repair
Prior mesh is not always removed. If old mesh is well-incorporated and not infected, it is often left in place and new mesh is added in a different plane. Mesh removal carries significant risk and is reserved for specific indications — infection, erosion, severe chronic pain attributed to the mesh.
What to ask before recurrent repair
- How many recurrent repairs do you perform per year?
- What approach are you recommending and why, given my prior operation?
- Will you attempt to remove or leave the prior mesh?
- What is your recurrence rate for recurrent repair specifically?
- What is the plan if more complex reconstruction is needed intraoperatively?
Bottom line
Recurrent hernia repair is not the same operation as primary repair. The technical demands are higher, the complication risk is higher, and the choice of approach matters more. A surgeon who performs recurrent and complex hernia repair as a regular part of their practice is the appropriate consultant — not the surgeon who performed the original operation by default.
