BACKGROUND: In ventral hernia repair, closure of the defect is one of the most significant challenges, especially in a wide defect, large hernias with loss of domain, and recurrent hernias. Posterior component separation with transverses abdominis muscle release (TAR) is a novel approach that offers a solution for complex ventral hernias. AIMS AND OBJECTIVES: To assess the clinical effectiveness of posterior abdominal wall components separation with transversus abdominis muscle release (PCS-TAR) in the management of ventral abdominal hernia with loss of domain. METHOD: The posterior component separation by transversus abdominis muscle release (simply TAR) is a modification of the Rives-Stoppa procedure which combines it with developing of a large retro-muscular/pre-peritoneal plane and a consistent medial advancement of the abdominal wall musculature and accompanying fascia. This preserves the neurovascular bundles innervating the medial abdominal wall. Mesh is placed in a sublay fashion above the posterior layer. In an overwhelming majority of patients, the linea alba is reconstructed, creating a functional abdominal wall with wide mesh reinforcement. RESULT: We used this procedure in a case of large median ventral incisional hernia. Our patient was a known post-operative case of exploratory laparotomy for ileal perforation following blunt abdominal trauma. Ileostomy was done due to gross intraperitoneal contamination. His post-operative recovery was complicated by wound dehiscence previously. Patient presented with a hernia along the midline wound with a gap of 12*7 cm. After the abdominal wall reconstruction procedure (TAR) with mesh placement over posterior rectus sheath (15*20cm) his post op recovery was uneventful. There was no recurrence till follow up of 3 months. CONCLUSION: TAR seems to be the effective approach for complex hernias with good immediate outcomes.

Many experts in abdominal wall reconstruction believe that the combination of simultaneous ipsilateral anterior component separation (ACS) and posterior component separation (PCS) is contraindicated. We performed ipsilateral endoscopic ACS and either endoscopic or open PCS-transversus abdominis release (TAR) in 5 fresh cadaver models. The full length of the semilunar line and the lateral abdominal wall remained well reinforced by 2 complete layers, comprising the internal oblique (IO) and TA muscles and their investing fasciae. Myofascial releases occurred 4 cm (median) apart. Additionally, we reviewed computed tomography images at 1 month and 1 year after PCS-TAR in 17 patients (30 PCS-TARs). Lateral displacement of the TA relative to the rectus abdominis (RA) was significant only at the superior mesenteric artery level, where it was <1 cm (median). Muscle mass changed minimally over time. Several studies showed that abdominal wall reconstruction after PCS-TAR results in compensatory muscular hypertrophy of the RA, external oblique (EO), and IO muscles and provides better quality of life and improved core physiology. These changes did not occur when the midline was not restored. Theoretically, endoscopic ACS-EO may be added to PCS-TAR to avoid partially bridged mesh repair in patients in whom complete midline restoration is impossible via PCS-TAR alone. Nevertheless, we advise most surgeons to perform a small-bridged repair instead of risking increased morbidity by attempting a highly complicated procedure.

Abstract Aim Complex ventral hernia (CVH) treatment due to large abdominal wall defects or loss of domain is challenging. BTA-injection in lateral abdominal wall causing flaccid paralysis and elongation, so called chemical component separation (CCS), might facilitate closure of large fascial defects. Combining preoperative progressive pneumoperitoneum might help restore abdominal content in severe loss of domain situations. We studied the results after CAWR following abdominal wall preparation with BTA and possible PPP. Primary aim was to report fascial defect closure rate without need for surgical component separation. Material and Methods All electively operated patients to date that were treated preoperatively with BTA, including all patients treated with PPP. Results Hospital index patient received preoperative BTA in January 2018. Since then, altogether 42 patients underwent CCS prior to CAWR. Average patient suffered from obesity (mean BMI 31), 30% had diabetes, and a third were active smokers. Mean hernia defect area exceeded 200 cm2. All operations were mesh repairs. Surgical approach was mostly (88%) open retromuscular. Abdominal wall reconstruction via fascial closure was achieved in 93% of cases with only 21% needing surgical component separation. Preoperative morbidity was common in patients undergoing PPP. Around 40% of all patients had postoperative complications, half of which were surgical complications. One patient died of a yet unknown cause on the third postoperative day. There were no recurrences within median 15 months follow-up. Conclusions Restoring abdominal wall continuity without frequent need for surgical component separation seems likely in CVH following CCS.

Abdominal Reconstruction

AbstractThe principle of targeted separation or weakening of individual components of the abdominal wall to relieve tension in the median line during major abdominal reconstruction has been known for over 30 years as anterior component separation (aCS) and is an established procedure. In search of alternatives with lower complication rates, posterior component separation (pCS) was developed; transversus abdominis release (TAR) is a nerve-sparing modification of pCS. With the ergonomic resources of robotics (e.g., angled instruments), TAR can be performed in a minimally invasive manner (r-TAR): hernia gaps of up to 14 cm can be closed and a large extraperitoneal mesh implanted. In this video article, the treatment of large incisional hernias using the r‑TAR technique is presented. Exemplary results of a cohort study in 13 consecutive patients are presented. The procedure is challenging, but our own results—as well as reports from the literature—are encouraging. The r‑TAR is becoming the pinnacle procedure for abdominal wall reconstruction.
