If you have been diagnosed with a hernia, you will quickly discover that there is more than one way to fix it. Open repair has been performed for over a century. Laparoscopic (keyhole) repair became mainstream in the 1990s. Robotic-assisted repair is the most recent development, and the one patients ask me about most.
As a surgeon who performs all three techniques, I have no commercial reason to steer you towards any one of them. This guide explains how they actually differ — and the questions that determine which is right for you.
Open hernia repair
A single incision is made directly over the hernia. The protruding tissue is returned to the abdomen and the weakness is reinforced, almost always with a flat mesh placed on top of the muscle layer (an "onlay" or Lichtenstein-type repair for groin hernias).
Strengths: it can be done under local or spinal anaesthetic in patients unfit for a general anaesthetic; it is well suited to very large or irreducible hernias; and for a first-time, one-sided inguinal hernia the long-term results are excellent.
Trade-offs: a larger scar, more early wound discomfort, and a slightly higher rate of chronic groin pain compared with keyhole approaches in some studies.
Laparoscopic (keyhole) repair
Three small incisions of 5–10 mm are used. A camera and fine instruments allow the mesh to be placed behind the muscle wall, where intra-abdominal pressure pushes the mesh against the defect rather than away from it — a mechanically advantageous position.
Strengths: less post-operative pain, faster return to driving, work and sport, smaller scars, and the ability to repair both groins through the same three incisions if you have hernias on both sides. It is also usually the better option for recurrent hernias previously repaired with an open technique, because the surgeon works in fresh, unscarred tissue planes.
Trade-offs: it requires a general anaesthetic, and outcomes are strongly linked to the surgeon's keyhole experience.
Robotic-assisted repair
Robotic surgery is keyhole surgery performed with a robotic platform: the surgeon controls wristed instruments from a console with a magnified 3D view. The robot does nothing on its own — it translates the surgeon's hand movements with greater precision and a far wider range of motion than straight laparoscopic instruments.
Where it earns its place: complex and recurrent hernias, larger ventral and incisional hernias requiring extensive suturing, repairs where the abdominal wall needs reconstructing rather than simply patching, and patients in whom precise mesh fixation with sutures (rather than tacks) may reduce post-operative pain. I explain the technique in more detail in my guide to robotic hernia surgery in Warwickshire.
Trade-offs: slightly longer operating times, and availability — relatively few surgeons in the region offer it privately.
What the evidence says
Large comparative studies, including a 2024 analysis of inguinal hernia repair outcomes presented by the American College of Surgeons, reach a consistent conclusion: open, laparoscopic and robotic repair all produce excellent results with low recurrence when performed by experienced surgeons. The technique matters less than the experience of the person performing it — which is why repair volume and audited outcomes should be part of your decision. I have set out the questions worth asking in How to Choose a Hernia Surgeon.
How I match the operation to the patient
- First-time, one-sided groin hernia, fit patient: keyhole or open both reasonable; keyhole usually recovers faster.
- Bilateral groin hernias: keyhole or robotic — both sides through the same small incisions.
- Recurrent hernia after open repair: keyhole or robotic, approaching from behind in untouched tissue.
- Large incisional or ventral hernia: robotic repair allows sutured closure of the defect and precise retromuscular mesh placement.
- Patient unfit for general anaesthetic: open repair under local or spinal anaesthetic.
Recovery expectations for each approach — including when you can drive, work and train — are covered in my hernia recovery guide.
Frequently Asked Questions
Is robotic hernia surgery safer than laparoscopic?
Both are forms of keyhole surgery and in experienced hands both are very safe. The robotic platform adds precision, 3D vision and fully wristed instruments, which is most valuable in complex, recurrent or large hernias. For a straightforward first-time hernia, a well-performed laparoscopic repair gives comparable results.
Which hernia repair has the fastest recovery?
Keyhole approaches — laparoscopic or robotic — generally allow a faster return to driving, work and exercise than open repair, typically within one to two weeks for desk-based work. Individual recovery varies with the size of the hernia and the type of repair.
Does the robot perform the operation?
No. The robotic system has no autonomy. The consultant surgeon controls every movement from a console in the same theatre; the platform simply translates those movements with greater precision than handheld instruments.
Can every hernia be repaired with keyhole surgery?
Most can, but not all. Very large long-standing hernias, some emergency presentations, and patients who cannot safely have a general anaesthetic may be better served by an open repair. This is exactly why it helps to see a surgeon who performs all three techniques.
