Abdominal Wall Reconstruction

Who Needs Abdominal Wall Reconstruction?

• Patients with large incisional hernias — often following prior open abdominal surgery (such as a midline laparotomy)
• Patients whose hernias have recurred after one or more prior repair attempts
• Loss of domain — where a significant volume of abdominal contents has migrated into the hernia sac and the abdominal cavity has contracted, making simple reduction impossible
• Patients with infected or exposed mesh from prior repairs
• Patients with significant diastasis recti (separation of the rectus muscles) combined with a hernia

Surgical Techniques

Component Separation

Component separation is a technique that releases specific muscle layers of the abdominal wall, allowing the surgeon to advance the muscles back to the midline and achieve a tension-free closure. The two primary approaches are:

• Anterior component separation — releasing the external oblique muscle aponeurosis
• Posterior component separation (Transversus Abdominis Release, or TAR) — releasing the transversus abdominis muscle to create a retromuscular space for mesh placement. TAR has become the preferred technique for many complex reconstructions due to the large retromuscular pocket it creates for mesh and the low recurrence rates reported in surgical literature

Mesh Reinforcement

Mesh is almost always used in abdominal wall reconstruction to reinforce the repair and reduce recurrence rates. The type and placement of mesh (retromuscular, intraperitoneal, or onlay) depend on the specifics of the defect and whether contamination is present. In contaminated or infected fields, biologic mesh may be used as a bridge to future definitive repair.

Robotic-Assisted Reconstruction

For appropriately selected patients, robotic-assisted abdominal wall reconstruction — including robotic TAR — offers the benefits of minimally invasive surgery (smaller incisions, reduced wound complications) while still achieving the structural goals of open reconstruction. The robotic platform is particularly well-suited to the dissection required for component separation.

Recovery

Abdominal wall reconstruction is more involved than a standard hernia repair, and recovery is correspondingly longer:

• Hospital stay: Typically two to five days, depending on the complexity of the repair
• Activity restrictions: Heavy lifting is restricted for six to eight weeks to allow the repair to gain strength
• Abdominal binder: A supportive binder is typically worn for several weeks after surgery
• Full recovery: Most patients return to full, unrestricted activity within eight to twelve weeks

Why Expertise Matters

Abdominal wall reconstruction is one of the most technically demanding areas of general surgery. The surgeon must understand the anatomy of the abdominal wall in detail, select the appropriate technique for each patient's unique defect, and manage mesh placement in a way that minimizes recurrence and complications. Dr. Abbassi brings the training and experience needed to navigate these complex cases for patients in Rockwall, McKinney, and across North Texas.

Frequently Asked Questions

What is a TAR hernia repair?

TAR stands for Transversus Abdominis Release. It is a type of posterior component separation where the transversus abdominis muscle is released to create a large retromuscular space for mesh placement. This technique allows tension-free closure of even very large abdominal wall defects and is associated with low recurrence rates.

Can a hernia that has been repaired multiple times still be fixed?

Yes. Multi-recurrent hernias are among the most challenging cases, but abdominal wall reconstruction techniques — particularly component separation with mesh reinforcement — can successfully restore abdominal wall integrity even after multiple failed repairs. A thorough evaluation with Dr. Abbassi can help determine the best approach for your situation.
