Laparoscopic surgery is often described as “keyhole” or minimally invasive surgery, which can make it sound automatically better. Open surgery, meanwhile, involves a larger incision and may seem like the more traditional option. But the choice is not quite that simple.
Both open and laparoscopic hernia repair are established surgical techniques. The better option depends on where your hernia is, whether it is on one or both sides, whether it has been repaired before, its size and complexity, your previous operations, your general health, and the surgeon’s experience with each technique. The overall aim of hernia repair is to return the protruding tissue to its proper position and strengthen the weak area so that the hernia is less likely to return.
What Is the Main Difference Between Open and Laparoscopic Hernia Repair?
*AI-generated image - for illustration only. Clinical accuracy is not guaranteed.
During laparoscopic hernia repair, several small incisions are made. A camera called a laparoscope and specialised surgical instruments are inserted through these openings so the surgeon can repair the hernia from inside. Mesh is commonly used to reinforce the weak area in many adult hernia repairs, although the exact technique depends on the type of hernia and individual circumstances.
| Open Hernia Repair | Laparoscopic Hernia Repair |
|---|---|
| Usually involves one larger incision near the hernia | Uses several small abdominal incisions |
| The hernia is approached directly | The hernia is repaired internally using a camera and instruments |
| Some repairs can be performed without general anaesthesia | Usually requires general anaesthesia |
| May be especially useful for certain large or complex hernias | Can offer faster early recovery in appropriately selected patients |
| Common and well-established technique | Established minimally invasive technique requiring specific surgical expertise |
| One larger scar | Several smaller scars |
Which Approach Causes Less Pain?
This is understandably one of the first things patients want to know. For inguinal hernia repair, laparoscopic surgery is often associated with less early postoperative pain and numbness compared with open repair.
Which Has a Faster Recovery?
For many uncomplicated inguinal hernias, laparoscopic repair can allow an earlier return to normal activities compared with open surgery. But “faster recovery” should not be interpreted as “fully healed within a few days.”
Which Surgery Leaves a Smaller Scar?
Laparoscopic repair usually produces several small scars across the abdomen. Open surgery produces one longer scar near the site of the hernia. If cosmetic appearance matters to you, this can be worth discussing with your surgeon, but scar size should not be the main factor used to choose an operation. The safest and most durable repair is more important than having the smallest possible incision.
Which Has a Lower Risk of Infection?
For inguinal hernia surgery, minimally invasive repair may have a somewhat lower risk of wound-related problems because there is no larger incision directly through the groin. However, infection can occur after either technique. Personal factors also matter. Smoking, poorly controlled diabetes, obesity, immune suppression, and other health conditions can affect wound healing and infection risk regardless of the surgical approach.
Can a Hernia Come Back After Either Operation?
Yes. A hernia can recur after both open and laparoscopic repair. When modern techniques are used appropriately by experienced surgeons, recurrence rates for inguinal hernia repair can be low with either approach. Recurrence depends on much more than incision size. Factors can include:
- The type and size of the hernia
- Surgical technique
- Mesh choice and placement when mesh is used
- Previous hernia repairs
- Smoking
- Obesity
- Wound complications
- Individual tissue quality
So it would be misleading to say that one approach always guarantees a lower chance of recurrence.
What About Long-Term Groin Pain?
Persistent groin discomfort is an important consideration after inguinal hernia repair. Nerves pass through the groin, and they may occasionally become irritated or affected during surgery or healing.
Minimally invasive inguinal hernia repair may reduce the likelihood of some chronic pain problems compared with open repair, although long-term pain can still occur after either approach. Persistent pain after surgery deserves medical assessment, particularly when it interferes with walking, work, sleep, or normal daily activities.

When May Laparoscopic Repair Have a Particular Advantage?
There are some situations where a laparoscopic approach may be especially useful.
Hernias on Both Sides
If someone has an inguinal hernia on both the right and left sides, laparoscopic surgery can allow the surgeon to repair both sides through the same small abdominal access points. This can make minimally invasive repair particularly attractive for suitable patients with bilateral inguinal hernias.
A Hernia That Returned After Previous Open Surgery
If an inguinal hernia comes back after an open repair, a laparoscopic approach may allow the surgeon to reach the hernia through a different tissue plane instead of operating again through the previous groin scar. Likewise, if a hernia has recurred after a posterior or laparoscopic repair, an open anterior approach may sometimes be preferred. The general idea is to avoid repeatedly operating through heavily scarred tissue when a suitable alternative route is available.
When Might Open Hernia Repair Be Preferred?
Open surgery remains extremely useful and may be preferable in several circumstances. Examples can include certain:
- Large hernias
- Complex abdominal wall defects
- Very large inguinal or scrotal hernias
- Emergency hernias
- Patients in whom general anaesthesia is undesirable
- Patients with previous operations that make laparoscopic access difficult
Some open inguinal repairs can be performed using local anaesthesia with sedation rather than general anaesthesia, which may be useful for selected patients.
What If You Have Had Previous Abdominal Surgery?
Previous abdominal operations can leave scar tissue inside the abdomen. This does not automatically prevent laparoscopic hernia repair, but the location and extent of the previous operation may affect whether minimally invasive access is practical or safe.
Your surgeon will consider:
- Where the previous incision was made
- What operation was performed
- Whether significant scar tissue is expected
- The position of the current hernia
This is another example of why the choice cannot be made from the words “open” and “laparoscopic” alone.
Does the Comparison Change for Ventral or Incisional Hernias?
Yes—and this is important. Much of the straightforward open-versus-laparoscopic comparison patients encounter online relates specifically to inguinal or groin hernia repair. Ventral and incisional hernias can be very different.
An incisional hernia, for example, develops through or around the scar from a previous abdominal operation. Some may be relatively small, while others involve a much larger area of the abdominal wall. For larger or more complex ventral and incisional hernias, the surgeon may need to consider:
- The width of the abdominal wall defect
- Whether the muscles can be brought back together
- Where mesh can be placed safely
- Previous abdominal operations
- Existing scar tissue
- Skin and wound condition
- Whether abdominal wall reconstruction is needed
In these cases, both open and minimally invasive approaches may be appropriate depending on the individual anatomy and surgical plan.
You can learn more about this type of abdominal wall hernia in our guide to ventral hernia.
Does Laparoscopic Surgery Always Mean a Shorter Hospital Stay?
Not necessarily. Many uncomplicated hernia repairs—both open and laparoscopic—can be performed as day surgery. Whether you stay overnight depends on factors such as:
- Your age and general health
- The complexity of the operation
- The type and size of the hernia
- How you recover from anaesthesia
- Pain control
- Whether you can eat, walk, and urinate normally
- Whether complications occur

A small uncomplicated open repair may therefore involve a much easier recovery than a complicated laparoscopic abdominal wall reconstruction.
Does Laparoscopic Hernia Repair Always Require General Anaesthesia?
Usually, yes. Laparoscopic hernia repair generally requires general anaesthesia because the abdomen needs to be inflated with carbon dioxide and the surgeon works internally using specialised instruments.
Open inguinal hernia repair offers more flexibility and may sometimes be performed using local anaesthesia with sedation, spinal anaesthesia, or general anaesthesia. For someone with health problems that make general anaesthesia less desirable, this difference may influence the surgical plan.
Which One Is Better for an Inguinal Hernia?
For an uncomplicated inguinal hernia, both open and laparoscopic repair can provide effective treatment. Laparoscopic repair may be particularly attractive when:
- A faster early recovery is important
- The patient has hernias on both sides
- A previous open repair has failed
- Reducing postoperative groin pain is an important consideration
Open repair may be particularly useful when:
- General anaesthesia should preferably be avoided
- The hernia is very large or extends significantly into the scrotum
- Previous abdominal surgery makes minimally invasive access difficult
- The clinical situation is better suited to direct open access
These are general patterns, not absolute rules.
What Matters More Than the Size of the Incision?
One factor patients sometimes overlook is surgeon experience with the chosen technique. Laparoscopic hernia surgery has a learning curve and requires specific training. Open repair also includes multiple techniques that require appropriate expertise. A theoretically ideal operation performed without sufficient experience is not automatically better than another established approach performed well.
- Why do you recommend this approach for my hernia?
- Is my hernia straightforward or complex?
- Will mesh be used, and where will it be placed?
- What type of anaesthesia will I need?
- What recovery should I realistically expect?
- What are the main risks in my particular case?
*AI-generated image - for illustration only. Clinical accuracy is not guaranteed.
So, Which Is Better: Open or Laparoscopic Hernia Repair?
There is no universal winner. Laparoscopic repair can offer smaller incisions, less early discomfort, and faster recovery in many appropriately selected patients—particularly for inguinal hernias.
But open surgery remains an excellent and sometimes preferable option, especially when anaesthesia considerations, previous operations, large hernias, complex anatomy, or the need for more extensive abdominal wall reconstruction influence the decision. The type of hernia matters too. Evidence that supports laparoscopic repair for one type of inguinal hernia should not automatically be applied to a large incisional or ventral hernia.
