Introduction
In abdominal wall reconstruction, the retro rectus plane presents an excellent site for mesh placement. However, mesh fixation in this site is usually executed utilizing transracial sutures, which risk entrapping intercostal nerves and inducing consequential pain, and will take time to place. An alternative is the usage of sutureless self-adhering mesh. Laparoscopic repair of ventral abdominal hernias normal care.
The surgery includes the arrangement of a composite mesh with a three to five-cm overlap at the borders of the fault. The drawback of this type of restoration is the composite mesh used for intraperitoneal placement is expensive, leaving a foreign body inside the peritoneal cavity, possibly generating future problems. To avoid these problems, we have created a renewed process called the retro rectus sub-lay mesh repair, which allows the sequence of a plain polypropylene mesh in an extraperitoneal plane.
What Is Retro-rectus Placement Surgery?
Incisional ventral hernias are a predominant problem, affecting up to ten percent of patients who have undergone laparotomy. During the initial hernia repair period, executing the most stable reconstruction is significant as the threat of hernia recurrence improves with every subsequent reconstructive try. Multiple well-designed analyses have revealed that most of the repairs should be strengthened with mesh to decrease the recurrence of the hernia.
Also, primary fascial reapproximation should be obtained to reduce the risk of recurrence and bulge. Similarly, to reduce the risks of surgical-site occurrences and hernia recurrence, the ideal place for mesh placement is the retro rectus plane, with at least 4 cm of overlap between the mesh and the fascia on both sides. This highly vascular plane is especially tempting as it avoids contact between the mesh and the intra-abdominal contents and protects the mesh from exposure if any complications result from wound healing.
The fixation of mesh in the retro rectus plane can be achieved by utilizing the stitches done at the center of the mesh and the sheath reflection of the rectus at the semilunar plane. Also, percutaneous sutures can be seated via the anterior rectus sheath or through the obliques or transversus abdominis complex, which endangers entrapping intercostal nerves in the sutures or even de-vascularizing components of the muscle. Another choice, which is the method assessed, is the usage of self-adhering mesh.
What Are the Preoperative Measures Done in Patients Undergoing Retro-rectus Placement Surgery?
-
In patients, the surgery begins with an exploratory laparotomy, including lysis of adhesions. The retro rectus plane was then created: palpation was done on the rectus muscles on both sides, mentioning that they were often little lateralized. Manual palpation was used to recognize the medial edge of all the rectus muscles. A small incision was created along the medial rectus reflection, which is resumed superiorly and inferiorly. The rectus muscle and the retro rectus fat were then removed rectus sheath on the back side, beginning towards the cranium and the medial plane and directing caudally and toward the lateral plane. With a special carefulness caudal to the arcuate line, retaining the continuity of the posterior sheath. Special care should be executed to prevent damage in the inferior epigastric artery to give their axial blood supply to the muscles.

The retro rectus plane is built laterally to the semilunar line, sustaining segmental motor nerves to the rectus muscles. After retro rectus planes are constructed on both sides, they are connected across the midline cranially and caudally to start a contiguous space to acquire the mesh. After this, the capability to seal the posterior rectus sheath is evaluated. Two Kocher or Allis clamps are kept on the medial edge of the posterior rectus sheath on both sides, and an attempt was made to reapproximate the two sides in the midline. If there is any unnecessary tension at that point, the unilateral or bilateral minimally invasive anterior component split is done, identical to the definition by Butler and Campbell, with minimal skin undermining.
Also, unilateral or bilateral posterior component detachment is done, similar to the explanation by Novitsky et al. The options to execute separation of anterior or posterior components relied on several factors: in patients with very wide defects, in patients, with an additional excursion of both the anterior and posterior sheaths is required, and in those with preexisting skin undermining, in whom anterior component partition would not need to be significant additional undermining, anterior component separation was executed. In difference, the components partition was executed on the backside in patients with moderately sized defects in whom additional excursion is required in the sheath of the back side and not the front sheath, not in the previously present skin. The front-side component split and rearward component detachment were not integrated into the exact patient. The rearward sheath was reapproximated using single or double-directional running (#0-looped) polyglyconate sutures.
What Are the Advantages of Self-Adhering Mesh Over Transfascial Suture Fixation?
In the past, mesh with transfascial suture fixation was done. The main risk of transfascial sutures was the risk of entrapment of the intercostal nerve and also pain which was acute and chronic. Self-adhering mesh has a better outcome in this aspect, that is, in cases of self-adhering mesh, which is sutureless, and thus, they need fewer narcotics after the operation than those who had transfascially sutured mesh.
In both these cases, the preoperative narcotics are at the same rate for chronic pain. The contrast in postoperative narcotic necessity stayed when controlling for the presence of an epidural catheter. The usage of self-adhering mesh in inguinal hernia repair has been shown to result in less acute pain without impacting chronic pain. Decreasing acute pain is crucial in securing patient satisfaction and limiting patient suffering. Similarly, uncontrolled acute pain is accepted to improve the vulnerability to ]infections at the surgery site, especially problematic difficulties for patients experiencing abdominal wall reconversion. Those who are with additional discomfort tend to mandate large doses of narcotics.
Adverse effects of postoperative narcotics include constipation, nausea, and confusion. To reduce the pain and the requirement of narcotics in abdominal wall reconstruction, certain methods are recommended, such as instituting multimodal analgesia with non-opioid medications, performing a transversus abdominis plane block, and considering a neuraxial catheter. It was discovered that patients who received sutureless self-adhering mesh required particularly lower doses of opioids postoperatively resembled patients who accepted transfascially sutured mesh, with no deterioration in the reconstructive outcome.
What Are the Disadvantages of Self-Adhering Polyester Mesh?
It can be done only to a category of patients without current abdominal wall infection or contamination and those with an intact posterior rectus sheath. Another disadvantage is that it is not seated under significant tension using sutures. Still, it is just laid on top of the revised posterior rectus sheath with multiple points of adherence. Netting does not bear large pressure on the fascial healing repair in the early period after surgery.
Conclusion
Assessing the outcomes of incisional ventral hernia repair using self-adhering mesh has shown good outcomes in a low recurrence rate of hernia recurrence and low surgical site occurrence rate. Also explained lower narcotic requirements in patients who accepted self-adhering mesh resembled patients who received transfascially sutured mesh.
