Hernia repair surgery: local vs. general anaesthetic

Escrito por: Mr James Kirkby-Bott

There are three different types of anaesthesia that may be used in cases of surgery; general, epidural or local anaesthesia. Often, a procedure such as open hernia repair is performed under local anaesthetic as it is the most effective and comfortable choice for this type of technique.

One of our top surgeons Mr James Kirkby-Bott explains the main differences between local and general anaesthetic and what happens during surgery under both types of pain medicine.


Can local anaesthetic be used for both keyhole and open hernia repair?

No. You can only use local anaesthetic to perform an open repair. It is not possible to do a keyhole repair under local anaesthetic.

Who has had open inguinal hernia repair with local anaesthesia?

Local anaesthetic open hernia repair is a very popular technique with patients that have undergone this procedure and surgeons that have the experience to perform it well. There is good evidence from a series of thousands of patients that local anaesthetic repair is comfortable, safe and effective.

The British Hernia Society recommends it and many hernia clinics all over the UK recommend this technique as having equivalent or better outcomes compared to keyhole (laparoscopic) surgery or open repairs performed under general anaesthetic. It is suitable for anyone; I have even performed this successfully in those with serious mental illness and anxiety issues.

It is considered to be the safest technique with the quickest recovery in those usually felt to be too old or frail for a repair under general anaesthetic. In frail patients or those with a lot of other health problems that can affect recovery from general anaesthetic, having local anaesthetic repair can make surgery both feasible and day-case care also possible where otherwise a longer inpatient stay might have required.

However, it is a good choice of technique for anyone having groin hernia surgery. The limitation to local anaesthetic repair is the size of the defect and the body habits of the patient. Large hernias can be repaired successfully and comfortably in very slim patients while in patients who are overweight very large hernias are more difficult in obese patients any local anaesthetic repair is difficult or impossible to do comfortably.

How do I know if local anaesthesia is best for me? (instead of regional or general)

There are pros and cons to every technique. Each have their advocates and some techniques do suit some more than others. The following will hopefully explain the pros and cons of the techniques available. Consider the choice as being between an open or keyhole technique and then between a local and general anaesthetic approach.

To understand the difference, it is helpful to think of the risks of each. One aspect of local anaesthetic I like is that the patient can cough when asked during the procedure. This helps demonstrate that the hernia has been fully and completely repaired. It is not possible to check the quality of the repair in a patient that is asleep.



Open repair

Keyhole (laparoscopic) repair

What is the risk of the hernia recurring?

Up to 5% in a lifetime.

Up to 5% in a lifetime.

What is the chance of altered skin sensation?

Moderate risk, though most are temporary.

Low risk of happening.

What is the chance of bowel or bladder injury and the consequence?

No or very little chance

The chance is real but the risk is low. If it happens it is important to notice it at the time of surgery. If not, the consequence is severe, if not fatal

Is there a risk of chronic pain?

Approximately 0.5% can experience longstanding discomfort.

Less chance than with an open repair but still happens.

What is the recovery time?

For a one-sided (unilateral) hernia repair there is no proven difference in recovery time for keyhole over open repair.

For either technique, the recovery time is around 10 days to return to normal daily activity. Certain sports and occupations, however, might take longer (4-6 weeks) to get back to.



Local anaesthetic

General anaesthetic

Will I be awake?

Yes, unless some light sedation is used, but that is not suitable for everyone.

No, you will be fully unconscious and paralysed if having keyhole surgery.

Will I feel any pain?

A local anaesthetic is injected and like going to the dentist, this can sting for 15-20 seconds. Then the area becomes numb. You will be ‘aware’ that we are doing something, but not feel pain

No pain but you will have the discomfort of the first needles and anaesthetic agent that can last 15-20 seconds.

How long does the effect of the anaesthetic last?

About 6 hours initially but the total pain felt post-surgery seems to be less with a return to comfortable activity. You will still need some pain relief in the days that follow. No nausea or the ‘hangover’ effect of a general anaesthetic.

It takes about 30 minutes to 2 hours to recover and wake up. You will then feel discomfort, nausea and have a ‘hangover’ effect. This can last a couple of days.

Can hernia repair cause problems with passing urine?

There is less chance of not being able to pass urine with a local anaesthetic. Even in older and frailer patients with pre-existing prostate enlargement and altered urine flow, not being able to pass urine is rare. I have seen it once in 200 cases. The reason is with local anaesthetic no opiate painkillers are needed and the inflammatory effect of surgery is reduced.

Moderate to high risk depending upon any pre-existing prostate problems. A combination of opiate painkillers, pre-existing poor urine flow and the inflammatory effect of surgery can make passing urine impossible at least for a couple of days. Usually, a catheter is required in this group for 48 hours.


How long will my hospital stay be after my hernia repair surgery?


Daycare is the aim in all patients so that they go home on the same day. An overnight stay is recommended for those with no one at home especially if a general anaesthetic has been given.
