Recurrent hernia & complex abdominal wall reconstruction.

The large hernias, the ones that have come back, and the ones other repairs have not held. This is the work Ram is most often sent — and the area he founded a 6,000-member surgeons' community around. A reconstruction, not a patch.

Most hernias are straightforward. A few are not. A hernia that has recurred once or several times, a defect so wide the muscles no longer meet in the midline, a hernia complicated by previous mesh or infection, or one large enough that the abdomen has lost much of its contents — these are problems of engineering as much as surgery. They need to be planned and rebuilt, not simply closed over.

This is the centre of Ram's practice. He founded the Abdominal Wall Reconstruction Surgeons Community, now around 6,000 members, and sits on the Executive Committee of the Australia & New Zealand Hernia Society — and is regularly sent the difficult abdominal walls that other repairs have not held.

Why hernias recur

A recurrence is rarely bad luck. It usually traces back to one of a few causes:

  • A repair done under tension, so the closure was always pulling itself apart.
  • Mesh that was too small, or placed in a plane that could not hold.
  • Risk factors left unaddressed — obesity, smoking, poorly controlled diabetes, or a wound infection at the first operation.
  • A defect that was always too large for the technique used on it.

Understanding which of these applied is the first step, because a recurrent hernia repaired the same way it failed will usually fail again.

Assessment

Complex repair begins with a proper map of the problem. That generally means a CT scan to measure the defect, assess the muscle layers and look for loss of domain, alongside a review of previous operation records and any mesh already in place. The plan — which technique, which plane, what preparation — is built from that assessment rather than decided in theatre.

The reconstruction

The goal is always the same: bring the muscles of the abdominal wall back to the midline, close them without tension, and reinforce them with adequately sized mesh in a durable plane. How that is achieved scales with the defect.

Rives–Stoppa retromuscular repair

For most midline hernias of real size, mesh is placed behind the rectus muscles. The body's own pressure holds it, and the muscle is closed over the top — the workhorse of abdominal wall repair.

Component separation & transversus abdominis release (TAR)

When a defect is too wide to close even with a retromuscular repair, the muscle layers are deliberately released so the wall can stretch back to the midline without tension. TAR is a posterior release that also opens a large, well-vascularised space for mesh. This is the operation behind most large and recurrent reconstructions.

Robotic reconstruction

Selected retromuscular repairs and TAR can be performed with a robotic platform rather than through a long open incision. The wristed instruments make the suturing and mesh-plane work inside the wall more precise, and for suitable patients allow a complex repair to be done minimally invasively — though for the largest defects an open reconstruction remains the right call. The approach is matched to the defect.

The principle. A durable result comes from restoring the anatomy — muscles meeting in the midline, mesh in the right plane, no tension — and from fixing the reasons the last repair failed. The technique follows the defect, not the other way round.

Preparation matters as much as the operation

For large and recurrent hernias, what happens before surgery shapes the result. Weight loss, stopping smoking and good diabetic control measurably lower the risk of wound problems and another recurrence. Very large hernias with loss of domain sometimes need specific preparation of the abdominal wall so the abdomen can re-accommodate its contents. None of this is a delaying tactic — it is part of getting a difficult repair to hold.

Recovery

A large reconstruction is bigger surgery than a routine hernia repair. Expect several days in hospital, a gradual return over six to eight weeks or more depending on the size of the repair, and clear limits on lifting while the reconstructed wall consolidates. The trade-off is a wall rebuilt to last, rather than another patch likely to give way. Your specific recovery plan is discussed in detail beforehand.

Common questions

Recurrent & complex hernia — answered

Usually because the original repair was under tension, the mesh was too small or in the wrong plane, or risk factors — weight, smoking, diabetes, wound infection — were not addressed. A recurrent hernia is harder than a first repair and is best approached as a reconstruction, not another patch.
A family of techniques that release one of the muscle layers so the wall can be brought back to the midline and closed without tension. Transversus abdominis release (TAR) is a posterior version that also creates a large space for mesh — the operation behind most large reconstructions.
A hernia so large that much of the abdominal contents have come to live outside the abdominal cavity. Returning them requires careful planning, sometimes including preparation before surgery, because the abdomen has to re-accommodate its own contents.
Usually, yes. Weight loss, stopping smoking, good diabetic control and, for very large hernias, specific preparation of the abdominal wall all improve the result. This is treated as part of the operation, not a delay to it.
