Early observations and pilot data that first suggested a new direction
Open tissue repair (Bassini, Shouldice) dominated inguinal hernia surgery for a century, with recurrence rates of 5-15%. Lichtenstein's introduction of tension-free mesh repair in 1989 reduced recurrence to below 2% and fundamentally changed the field. The question then became whether laparoscopic approaches could match or improve upon open mesh repair.
Proof
Landmark RCTs and pivotal trials that established the evidence base
The EU Hernia Trialists Collaboration (2002) meta-analysis pooled data from multiple RCTs comparing laparoscopic to open repair. Laparoscopic techniques (TEP and TAPP) showed equivalent recurrence rates to open mesh repair with faster return to normal activities and less chronic pain, but longer operating times and higher initial costs. Separately, the observation that many inguinal hernias in men were minimally symptomatic led to trials of watchful waiting as an alternative to immediate surgery.
Follow-up studies, subgroup analyses, and real-world validation
The HerniaSurge international guidelines (2018) synthesised evidence across 900+ studies to produce comprehensive groin hernia management recommendations. These guidelines endorsed both open Lichtenstein and laparoscopic (TEP/TAPP) as acceptable techniques, emphasised the importance of surgical expertise over technique, and supported watchful waiting for minimally symptomatic inguinal hernias as a safe initial strategy.
Integration into clinical practice guidelines and recommendations
HerniaSurge and EHS guidelines recommend mesh-based repair as the standard for primary inguinal hernia, with both open Lichtenstein and laparoscopic approaches as valid options. The choice is guided by surgeon expertise. Watchful waiting is endorsed for minimally symptomatic hernias in men, with surgery reserved for when symptoms develop.

Now
Current standard of care and ongoing research directions
Inguinal hernia repair is one of the most commonly performed operations worldwide. The field has moved toward tailored approaches: laparoscopic repair for bilateral and recurrent hernias, open Lichtenstein for unilateral primary hernias, and watchful waiting for minimally symptomatic patients. Robotic-assisted repair is growing but evidence of superiority over standard laparoscopic techniques is lacking.
No. Watchful waiting is a safe initial strategy for minimally symptomatic inguinal hernias in men. HerniaSurge guidelines endorse observation with surgery reserved for when symptoms develop. However, femoral hernias always require repair due to high strangulation risk.
Is laparoscopic hernia repair better than open repair?+
The EU Hernia Trialists meta-analysis showed laparoscopic repair (TEP/TAPP) has equivalent recurrence rates to open mesh repair with faster return to normal activities and less chronic pain. However, laparoscopic approaches have longer operating times and a steeper learning curve. HerniaSurge guidelines recommend the choice be guided by surgeon expertise rather than technique alone.
