Mesh fixation in laparoscopic groin hernia repair: a comprehensive review of techniques and devices

Laparoscopic groin hernia repair has increased in popularity in recent years. Many laparoscopic mesh fixation techniques and devices are available, but there is a lack of high-certainty evidence favoring one fixation technique over another. This narrative review aimed to provide a comprehensive summary detailing the available mesh fixation techniques and devices used in laparoscopic groin hernia repair.

Information about mesh fixation techniques and devices was searched in PubMed, groin hernia guidelines, and medical technology companies webpages.

This review outlines various mesh fixation techniques, materials, and their features in laparoscopic groin hernia repair. We have summarized and presented in detail the available information on both penetrating and non-penetrating mesh fixation techniques, including the option of not fixating the mesh. Penetrating mesh fixation includes tacks, staples, and sutures. Tacks vary in size, absorption time, and shape and can be further categorized into absorbable and permanent materials. Additionally, this review describes two types of permanent titanium staples and the use of permanent and absorbable sutures as mesh fixation. Non-penetrating mesh fixation includes self-fixating mesh and glue. The types of glue are cyanoacrylate glue and fibrin sealant. While fibrin sealant requires careful thawing from a frozen state before use, cyanoacrylate glue offers easier storage but poses a risk of exothermic reaction with the surrounding tissue. Self-fixating meshes have an adhesive side made of microgrips or adhesive material, and a permanent side.

This review provided a comprehensive overview of the various mesh fixation techniques and devices in laparoscopic groin hernia repair.
