Laparoscopic vs open hernia surgery

There are two main approaches to hernia surgery: open surgery through a single incision directly over the hernia, and keyhole (laparoscopic) surgery through two or three smaller incisions placed away from the hernia site. Both approaches use a mesh to reinforce the repair, and in published series both achieve similarly low rates of recurrence. Neither is universally "better" — the right choice depends on you, your hernia, and your circumstances.

This page explains what each technique involves, how recovery compares, and when one is typically recommended over the other.

The most common form of open inguinal hernia repair is called the Lichtenstein repair. It involves a single cut of around 5–7 cm in the groin, directly over the hernia. The hernia is identified and gently pushed back into place, and a flat piece of mesh is placed over the groin floor and stitched in position to reinforce it.

Key things to know about open repair:

• Can be done under local, regional (spinal), or general anaesthesia — which means it is an option for people who cannot safely have a general anaesthetic
• The operation itself takes approximately 30–45 minutes for one side
• You go home the same day in most cases
• Gives direct, clear access to the hernia — a particular advantage with very large hernias or unusual anatomy
• More wound discomfort in the first 1–2 weeks compared to keyhole surgery
• If both sides need repair, two separate groin incisions are needed

Keyhole hernia repair is done through two or three small cuts of 5–10 mm, placed near the navel and lower abdomen rather than directly over the hernia. Using a tiny camera and fine instruments, the surgeon approaches the hernia from behind the abdominal wall and places a larger mesh in the space behind it — covering both the groin and femoral spaces on that side.

There are two main keyhole techniques:

• TAPP (transabdominal preperitoneal) — the surgeon enters the abdominal cavity, opens the inner lining, places the mesh, then closes the lining back over it
• TEP (totally extraperitoneal) — the repair is done entirely in the space behind the abdominal wall, without entering the abdominal cavity itself

Both techniques require general anaesthesia. The operation takes around 45–60 minutes for one side, slightly longer for both sides.

Hernias on both sides

If both your groins are affected, keyhole surgery has a clear advantage: both hernias can be repaired in a single operation through the same small incisions, with one large mesh covering both sides at once. Open surgery would require two separate groin cuts, which means more wound discomfort.

A hernia that has come back after open surgery

If your hernia has recurred after a previous open repair, the tissue in your groin will be scarred from the first operation. Going back in through that scar is technically difficult and carries a higher risk of damage to delicate nearby structures. Keyhole repair approaches from a completely different direction — a space that was not touched by the previous operation — making it the preferred approach in this situation.

People whose work is physically demanding

In published series, keyhole repair is associated with less wound pain and a faster return to physical activity — typically 2–4 weeks compared with 4–6 weeks for open repair in people doing manual work. If your livelihood depends on being physically active, this can make a real difference to the impact of surgery on your life.

• If general anaesthesia is not suitable for you — open repair can be done under local or spinal anaesthesia, which makes it a useful option if you have heart or lung conditions that make a full general anaesthetic riskier
• A hernia that has come back after keyhole surgery — if your previous repair was done by keyhole, the space behind the abdominal wall will be scarred, making another keyhole approach more difficult; open repair is then preferred
• Very large hernias — direct access through an open incision can be an advantage when the hernia is large or the anatomy is complex
• Emergency surgery — a hernia that becomes trapped or strangulated is usually managed through an open approach because it is faster and provides the most direct access
• Your surgeon's experience — results are closely tied to how experienced your surgeon is with a given technique. Your surgeon will use the approach they are most skilled in for your specific hernia — and they will tell you why

Both operations are done as day procedures in most cases — you go home the same day and can move about from that first evening. The key differences in how recovery feels are:

• Wound discomfort — open repair causes more wound pain in the first 1–2 weeks; keyhole repair causes less wound pain but may produce a shoulder-tip ache from the gas used to inflate the abdomen during surgery (this resolves within 24–48 hours)
• Getting back to desk work — both approaches: typically 1–2 weeks
• Getting back to driving — usually 1–2 weeks, once you can perform an emergency stop comfortably without pain. Check with your surgeon and your insurer.
• Light gym and physical activity — keyhole: 3–4 weeks; open: 4–6 weeks
• Heavy lifting and manual work — both: 6–8 weeks. The mesh needs the same amount of time to integrate regardless of which technique was used.

For long-term outcomes — in particular, the chance of the hernia coming back — both techniques are equivalent when performed by experienced surgeons. In published series both approaches achieve similarly low recurrence rates — roughly 1–3 in every 100 for keyhole inguinal repair and 2–5 in every 100 for open inguinal repair. Where keyhole repair has an edge is in the short-term recovery: studies show less post-operative pain and a faster return to normal life with keyhole surgery.

Chronic groin pain — an uncommon but real complication that can follow any hernia repair — appears to be slightly less common after keyhole repair in some studies, possibly because it avoids directly handling the nerves in the groin. This is still being studied, but it is worth knowing about if long-term comfort is a priority for you.
