Groin hernia repair: open techniques

Area of Science:

• Surgical Innovation
• Hernia Repair Techniques
• Biomaterials in Surgery

Background:

• Over 70 pure tissue repair methods for inguinal hernias exist since the Bassini method (1887).
• High recurrence rates and prolonged recovery from tissue repair led to tension-free mesh hernioplasty.
• Current repair categories include open and laparoscopic approaches, with open repairs using either tissue or mesh.

Purpose of the Study:

• To compare the efficacy and safety of tension-free mesh inguinal hernia repair versus traditional tissue approximation.
• To evaluate the optimal mesh placement strategy in open inguinal hernia repair: anterior versus posterior to the transversalis fascia.

Main Methods:

• Review of surgical literature detailing various inguinal hernia repair techniques.
• Analysis of comparative randomized trials evaluating mesh repair versus tissue repair.
• Examination of studies comparing anterior (e.g., Lichtenstein) versus posterior (e.g., Nyhus, Stoppa) mesh placement in open repairs.

Main Results:

• Numerous randomized trials demonstrate the superiority of tension-free mesh repair over pure tissue approximation.
• Posterior preperitoneal mesh placement requires extensive dissection, risks pelvic structure injury and hematoma.
• Prospective studies show no advantage of posterior over anterior mesh placement, with increased procedural difficulty.

Conclusions:

• Level A evidence confirms mesh repair is superior to pure tissue approximation for inguinal hernias.
• Mesh implantation anterior to the transversalis fascia is superior, safer, and easier than posterior preperitoneal placement.
• Posterior mesh placement complicates future pelvic surgeries and offers no additional benefit over anterior placement.
