Laparoscopic hernia repair--what are the results?

Area of Science:

• Surgical Innovation
• Minimally Invasive Surgery
• Hernia Repair Techniques

Background:

• Trans-abdominal preperitoneal (TAPP) and trans-extraperitoneal preperitoneal (TEPP) are established laparoscopic groin hernia repair methods.
• Open surgical techniques like Shouldice and Lichtenstein's are traditional standards for groin hernia repair.

Purpose of the Study:

• To evaluate the efficacy and safety of laparoscopic versus open techniques for groin hernia repair.
• To compare recurrence rates and complication profiles between laparoscopic and open methods.
• To assess the suitability of laparoscopic repair for recurrent groin hernias.

Main Methods:

• Review of existing literature and early results for TAPP and TEPP laparoscopic groin hernia repairs.
• Comparison of recurrence rates and complication data with standard open repair techniques.
• Analysis of outcomes for laparoscopic repair of recurrent groin hernias versus conventional methods.

Main Results:

• Laparoscopic techniques (TAPP, TEPP) demonstrate low recurrence rates (0-2%), comparable to open repairs.
• Initial laparoscopic repair may have higher complication rates due to surgeon learning curve, expected to decrease with experience.
• Laparoscopic repair shows significant superiority for recurrent groin hernias with zero recurrence rates compared to 1.5-35% for conventional repair.
• Open repair is associated with higher postoperative discomfort and societal costs due to prolonged work absence.

Conclusions:

• Laparoscopic groin hernia repair is a safe and effective alternative to open repair, with the learning curve now largely overcome.
• Laparoscopic techniques offer advantages, particularly for recurrent hernias, despite initial challenges.
• Further well-designed prospective randomized trials are needed to solidify evidence for laparoscopic groin hernia repair.
