Mesh was first introduced in the late 19th century when Witzel first used silver mesh in a groin hernia surgery. Many other materials were tested but none surfaced as the standard of care until the development of polypropylene mesh in 1954.
The advantages of mesh for hernia surgery included decreased postoperative pain and decreased hernia recurrence. While this has generally been accepted as the gold standard for abdominal wall hernias, rare complications such as mesh infections and foreign body irritation/mesh discomfort have led to the development of new forms of mesh—such as lightweight mesh, antibiotic coated mesh, absorbable mesh, and biocompatible mesh—in an attempt to improve outcomes and patient satisfaction.
In modern day hernia surgery, mesh can be divided into synthetic and biologic mesh types. Synthetic meshes such as polypropylene are permanent and nonabsorbable while biocompatible meshes (derived from human or animal materials) are integrated into the body.
Umbilical / Ventral / Incisional Hernia Repair
Surgical repair of Umbilical/Ventral/Incisional Hernias involves reducing the abdominal contents back into the abdomen and repair or the wall defect either primarily with suture or with a covered material placed over the defect, such as mesh.
Hernia surgery has been around for quite sometime, being identified as early as 1500 BC in Egyptian records and soon thereafter in Greek history. More recently in the 19th century advances in groin hernia surgery were made such as proper primary suture repair, the use of local anesthesia (Lidocaine), and the use of mesh.
With the advent of laparoscopic surgery in the 20th century and robotic surgery in the 21st, multiple approaches now exist to fix an abdominal wall hernia in addition to the standard open approach.
Depending on the severity of the hernia, hernia surgery is usually an outpatient procedure performed with general anesthesia with discharge the same day, however for more complex ventral hernias, observation in the hospital may be warranted. Most postoperative instructions include no heavy lifting or strenuous exercise for four to six weeks.
A hernia occurs when there is a hole in the muscles of the abdominal wall, allowing a loop of intestine or abdominal tissue to push through the muscle layer. A ventral hernia is a hernia that occurs at any location along the midline (vertical center) of the abdomen wall. There are three types of ventral hernia: Epigastric (stomach area) hernia, Umbilical (belly button) hernia, Incisional hernia.
Gentrix surgical mesh is a product produced by Acell and is used to repair hernia defects. The mesh falls into the category of surgical meshes called “biologics,” which describe mesh material whose purpose is to be incorporated and become part of the body over time. This is in contrast to “prosthetic” mesh, which is much more permanent.
