Inguinal hernia repair is one of the most common operations in general surgery. Today it can be performed in three main ways — open, laparoscopic or robotic — and all of them, in their modern form, use a synthetic mesh to reinforce the wall without tension. No single method is "best" for everyone; the right choice depends on the type of hernia and each patient's characteristics. Below we compare the pros and cons of each.

The three main approaches

  • Open repair: through a single groin incision, the mesh is placed in front of the defect (the best-known technique is the Lichtenstein repair).
  • Laparoscopic repair: through small ports, with a camera and fine instruments, the mesh is placed behind the wall. The two variants are TEP (totally extraperitoneal) and TAPP (transabdominal preperitoneal).
  • Robotic repair: follows the same principle as laparoscopy, but the surgeon controls the instruments through a robotic console with three-dimensional vision.

Open repair

This is the most established method, with decades of experience and excellent long-term results.

Advantages

  • It can be done under local or spinal anaesthesia — useful for patients with serious comorbidities who are not ideal candidates for general anaesthesia.
  • Lower cost and wide availability.
  • It remains an excellent option for large, incarcerated or emergency hernias.

Disadvantages

  • Often slightly more pain around the incision in the first days.
  • For bilateral hernias, two separate incisions are needed.

Laparoscopic repair (TEP / TAPP)

This places the mesh behind the wall, covering the whole "weak" area of the groin.

Advantages

  • Smaller incisions, less post-operative pain and a tendency toward a lower rate of chronic pain.
  • Faster return to daily activities and work.
  • Particularly useful for bilateral hernias (treated through the same ports) and for recurrences after a previous open operation.

Disadvantages

  • Requires general anaesthesia.
  • Has a more demanding learning curve for the surgeon.
  • Higher equipment cost compared with open repair.

Robotic repair

This is an evolution of the laparoscopic approach. The robotic console offers magnified three-dimensional vision and instruments that articulate like a human wrist.

Advantages

  • Excellent precision in dissection and easier suturing/fixation of the mesh.
  • Better ergonomics for the surgeon, which may help in more complex or recurrent cases.

Disadvantages

  • The highest cost of the three methods.
  • Longer set-up and, often, operative time.
  • Based on current evidence, clinical outcomes are broadly comparable to laparoscopy — the benefits are mainly technical/ergonomic rather than a clear advantage in results.

What the guidelines show

International guidelines (HerniaSurge) recommend the use of mesh in adults and consider both the open (Lichtenstein) and the laparoscopic approach acceptable for unilateral primary hernia, when performed by an experienced surgeon. The laparoscopic approach is often preferred for bilateral hernias and for recurrences after an open operation. For robotic repair, the evidence to date does not show superiority over laparoscopy in the main outcomes.

How the right method is chosen

The main factors taken into account are:

  1. Unilateral or bilateral hernia.
  2. Primary or recurrent (and with which previous technique).
  3. Size and characteristics of the hernia.
  4. Suitability for general anaesthesia and overall health.
  5. The surgeon's experience and familiarity with each technique.

Recovery and return to activities

With the minimally invasive methods (laparoscopic/robotic), return to light daily activities is usually faster, while avoiding heavy lifting is advised for a few weeks regardless of method. The exact timing is individualised and determined by your treating physician.

Which method hurts less?

In general, the laparoscopic and robotic approaches are associated with less early pain and a lower tendency toward chronic pain, but the difference is individualised to each case.

Is mesh always needed?

In adults, tension-free mesh repair is the rule, as it significantly reduces the risk of recurrence. There are exceptions that are assessed case by case.

When is the laparoscopic or robotic approach preferred?

Often for bilateral hernias, for recurrences after an open operation, and when a faster return to activities is desired — provided the patient is suitable for general anaesthesia.

Is robotic "better" than laparoscopic?

Based on current evidence, outcomes are comparable. Robotic repair offers technical and ergonomic advantages at a higher cost; the choice depends on the case and the team's experience.
