Incisional Hernia Surgery

Definition and Functional Impact of Incisional Hernia

Incisional hernias develop at the site of a previous surgical incision when healing of the abdominal wall is incomplete or progressively weakened. Their defining characteristic is prior surgical disruption of normal anatomy and tissue planes, creating a specific need for anatomical and functional restoration.

Incisional hernias combine a structural defect with altered tissue quality and often evolve over time. Symptoms range from mild discomfort to significant functional limitation, progressive enlargement or instability of the abdominal wall. As defects enlarge, reconstruction becomes more complex and requires comprehensive planning.

At Geneva Surgery, incisional hernias are approached as a reconstructive condition of the abdominal wall, rather than an isolated defect.

Clinical Assessment and Indications

Assessment includes detailed analysis of prior surgical history, defect characteristics, tissue quality and functional impact. Particular attention is paid to progression over time and to patient-specific factors that influence reconstructive strategy.

Imaging is used selectively to characterise complex anatomy, define hernia content and support accurate planning.
Surgical repair is generally recommended when incisional hernias are symptomatic, progressive or associated with functional impairment, with the objective of intervening before further deterioration occurs.

Surgical Strategy and Abdominal Wall Reconstruction

Reconstruction is planned as a global restoration of abdominal wall function, integrating compartment release and reinforcement strategies to re-establish physiological tension and durable performance.

Wide extraperitoneal reinforcement is a core element of reconstruction, supporting long-term stability while allowing re-establishment of normal biomechanical behaviour.

Principles of Abdominal Wall Reconstruction

Prosthetic choices are tailored to tissue quality and clinical context.

By avoiding intraperitoneal placement of foreign material, this approach reduces the risk of adhesions and long-term complications while supporting wide, stable reinforcement.

Extraperitoneal reinforcement allows stabilisation through anatomical reconstruction and tissue integration rather than extensive invasive fixation.

This limits tissue trauma, improves postoperative comfort and contributes to durable outcomes.

Robotic surgery is the standard operative modality.

It enables precise dissection and controlled reconstruction within altered anatomical planes. Its value increases exponentially with defect size, recurrence and tissue alteration, supporting safe and reproducible reconstruction in complex settings.

Loss of Domain and Preconditioning

In advanced incisional hernias, a significant portion of abdominal contents may reside chronically outside the abdominal cavity.

This situation, referred to as loss of domain, represents a physiological and reconstructive challenge that must be addressed during planning.

When indicated, preconditioning strategies are integrated to improve abdominal wall compliance and facilitate safe reintegration of herniated contents.

These may include targeted botulinum toxin injections to temporarily increase abdominal wall flexibility or progressive pneumoperitoneum to allow gradual physiological adaptation.

Compartment Release and TAR

In complex reconstructions, controlled abdominal wall compartment release may be required to achieve tension-free anatomical restoration.

The Transversus Abdominis Release (TAR) allows strategic mobilisation of deep muscular layers, supporting midline reconstruction and wide extraperitoneal reinforcement.

At Geneva Surgery, TAR has been adopted since its original description and is integrated into surgical planning when indicated.

Dr Inan has been teaching and proctoring this advanced technique internationally for more than a decade, contributing to its safe dissemination in complex abdominal wall reconstruction.

When combined with robotic surgery, TAR can be performed with precision and control, limiting surgical trauma and supporting durable functional outcomes.

INCISIONAL HERNIA

The following answers address the most common questions about incisional hernia, including symptoms, indications for surgery, preparation and recovery.

What is an incisional hernia?

An incisional hernia develops at the site of a previous surgical incision when healing of the abdominal wall is incomplete or progressively weakened. Unlike primary ventral hernias, incisional hernias result from prior surgical disruption of the abdominal wall anatomy and are associated with altered tissue quality. They often evolve over time and may increase in size or functional impact.

What symptoms can an incisional hernia cause?

Incisional hernias may present as a visible bulge, discomfort, pain or functional limitation. Symptoms can progress gradually and may interfere with posture, mobility or daily activities. Beyond local symptoms, incisional hernias can compromise abdominal wall function and core stability.

Does every incisional hernia require surgery?

Not necessarily. The indication for surgery depends on symptoms, functional impairment and individual risk profile. Some incisional hernias can be monitored safely, while others benefit from reconstruction to restore abdominal wall integrity and function. The decision is approached as a structured risk management process based on objective assessment.

Why are incisional hernias considered more complex?

Incisional hernias combine a structural defect with altered anatomy and reduced tissue quality due to previous surgery. Adhesions, scar tissue and muscle retraction increase technical complexity and influence reconstructive strategy. These factors require careful planning and tailored surgical execution.

What are the principles of incisional hernia repair at Geneva Surgery?

Repair follows modern reconstructive principles within a minimally invasive philosophy. The objectives are full anatomical restoration of the abdominal wall, wide extraperitoneal reinforcement for durability and functional reorganisation of the core. Avoidance of invasive fixation and minimisation of surgical trauma are central objectives. Functional restoration is prioritised over purely anatomical correction.

How are large or complex incisional hernias prepared?

Large or complex incisional hernias may require preoperative conditioning to optimise outcomes. Strategies such as abdominal wall preconditioning, including component separation techniques, progressive pneumoperitoneum or botulinum toxin when appropriate, are integrated within a structured multidisciplinary framework. The objective is to restore abdominal domain and facilitate safe reconstruction.

Why is robotic surgery used for incisional hernia repair?

Robotic surgery allows precise dissection in scarred and altered anatomical planes, controlled reconstruction and accurate placement of large extraperitoneal reinforcement. Its value increases with complexity and supports durable repair while limiting surgical trauma and conversion to open surgery.

How is recovery after incisional hernia surgery?

Recovery is structured and individualised. Pain management follows an opioid-free strategy, early mobilisation is encouraged and functional recovery is guided progressively. Patients remain hospitalised until predefined recovery criteria are achieved, ensuring a safe and predictable return to daily life.

Perioperative Care and Recovery

The same structured perioperative pathway applies to incisional hernia repair, ensuring consistency of care, safety and predictable recovery. Pain management follows an opioid-free strategy, mobilisation is prioritised, thrombosis prophylaxis is systematic and discharge criteria are clearly defined.

Expected Outcomes

Incisional hernia repair aims to restore abdominal wall integrity, stability and function while supporting long-term quality of life. Durable reconstruction and preservation of abdominal wall dynamics are central goals of treatment.
