Open inguinal hernia repair

Open inguinal hernia repair — sometimes called the Lichtenstein technique — is one of the most common operations performed anywhere in the world. It has built up a well-established track record over many decades. If you have an inguinal hernia (a bulge in your groin where bowel or fatty tissue has pushed through a weak spot in the abdominal wall), this operation fixes it through a single incision made directly in the groin area. The herniated tissue is gently eased back to where it belongs, and a flat mesh patch is then laid over the weak spot to reinforce it and prevent the hernia from pushing through again.

One of the things that makes open repair particularly flexible is the choice of anaesthetic. Depending on what is right for you, it can be done under local anaesthetic (only the groin area is numbed and you stay comfortably awake), spinal anaesthetic (the lower half of your body is numbed and you feel nothing below the waist — you're awake but feel no pain at all), or general anaesthetic (you're fully asleep). This flexibility means that people who can't safely have a general anaesthetic — for example because of heart or lung conditions — can still have the hernia fixed.

While keyhole surgery is often preferred when both sides are affected or a hernia has come back, open repair is a well-established choice for a straightforward, first-time hernia on one side — and is particularly well suited if you're older, or if other health conditions make keyhole surgery less ideal for you.

• You have a hernia on one side of your groin and you'd prefer to stay awake under a local or spinal anaesthetic rather than having a full general anaesthetic — that is a completely reasonable preference
• A general anaesthetic isn't safe for you because of heart, lung, or other health conditions — open repair under local anaesthetic is often a practical alternative that removes that concern entirely
• You have considered keyhole surgery but prefer the open approach — that is a perfectly valid choice, and your preference is respected at consultation
• Your hernia has become strangulated — meaning the tissue has become trapped and its blood supply is at risk. This is an emergency, and open repair is often the safest and most direct way to sort it out quickly
• You have a straightforward, first-time hernia on one side and open repair is simply the most appropriate option for your situation
• You've had significant abdominal surgery in the past that has left internal scarring — this can make the keyhole approach difficult or unsafe, while open repair avoids those areas entirely

• You can have this operation under local or spinal anaesthetic if a general anaesthetic isn't right for you — which means people who might otherwise be turned away from surgery can still have their hernia properly fixed
• This technique has been carefully refined over many decades and has a well-documented safety record
• The operation doesn't require CO2 gas to be pumped into your abdomen (which is how keyhole surgery works), making it a safer choice if you have heart or lung conditions that make gas insufflation undesirable
• It is one of the most widely performed operations in the world — every member of the surgical team is familiar with the technique
• In most cases this is a day procedure — you come in, have your surgery, and go home the same day
• A flat mesh patch is used to reinforce the weak area from the front, meaning the repair is under no tension and is built to hold firmly for the long term

• Long-term groin discomfort — this is the most important thing to understand about open repair. Roughly 5–15 people in every 100 notice some ongoing pain or sensitivity in the groin after the operation. For most, it is mild and fades over months. Published studies suggest keyhole repair carries a lower rate of this, which is part of the reason keyhole is often preferred when circumstances allow. That said, for many people the open approach is still the right operation, and what applies to your specific situation will be discussed at consultation
• Wound infection — affects about 1–3 in every 100 people; when it occurs it is almost always treated straightforwardly with a short course of antibiotics
• The hernia returning — about 2–5 in every 100 people at five years; in published series, this is slightly higher than after keyhole repair, but still a solid result for a well-established operation
• Nerve sensitivity — two small sensory nerves (the ilioinguinal and iliohypogastric nerves) run through the groin area and can be stretched or irritated during the repair. About 5–10 in every 100 people notice some numbness, tingling, or altered sensation in the groin or inner thigh afterwards. This often improves on its own over weeks to months
• Bruising or swelling around the testicle (called a haematoma) — uncommon, and usually resolves without treatment. Very rarely, there can be changes to the size of the testicle (testicular atrophy). The likelihood in your individual case will be discussed with you before your operation
• Seroma — a pocket of fluid that builds up in the space where the hernia used to sit. Occurs in about 5–10 in every 100 cases. It can look or feel as though the hernia has returned, but it almost always settles on its own without any treatment. If you notice swelling after going home, please call us before worrying — it is very likely just this

If you take blood thinners, diabetes medication, GLP-1 weight-loss injectables, or iron supplements, please flag this when you book — these need specific adjustments before the procedure. Full details are in the guide above.

• No bowel preparation is needed — there is no need to take laxatives or do anything special to prepare your bowels beforehand
• Before your operation, everything is explained in detail — what the mesh is and why it is used, the possibility of some ongoing groin sensitivity, and the nerve anatomy involved. This is your time to ask anything you want, and the consent form is signed only once you feel properly informed
• At your pre-admission appointment, a nurse will mark the correct side of your groin with a skin marker pen — this is a standard hospital safety step that happens for every patient, to make absolutely certain the right side is operated on

• You will be admitted to the day-surgery unit at Warringal Private Hospital or Epworth Eastern on the morning of your operation. You will receive the type of anaesthetic planned with your team — local (the groin area is numbed with injections and you stay awake), spinal (the lower half of your body is completely numbed so you feel nothing below the waist, though you are awake), or general (you are fully asleep and completely unaware of anything). All three are safe and effective options
• A single incision is made in your lower groin, just above the crease — typically about 5–7 cm long. This opens up the inguinal canal, which is the channel through which the hernia has passed
• The herniated tissue is carefully eased back to where it belongs. A flat mesh patch is then laid over the back wall of the inguinal canal and gently secured in place — this is what reinforces the weak area and stops the hernia from returning
• The incision is closed neatly in layers. The skin is closed with a fine dissolving stitch just under the surface, so there are no sutures to remove at a later appointment
• You will spend a couple of hours in the day-stay unit while everything settles, and most people are able to go home the same day
• Before you leave, a nurse will walk you through how to care for your wound dressing at home and what signs to watch out for — so you feel confident rather than uncertain when you get through your front door

• First 1–2 days: Rest at home. Your groin will be sore — this is completely normal and expected. Regular paracetamol taken as directed on the packet manages this well for most people. Your team may also suggest an anti-inflammatory such as ibuprofen if that is safe for you. Take it easy, accept help, and do not try to rush yourself
• Days 3–5: You will start to feel noticeably more like yourself. Gentle movement around the house is fine and is actually beneficial for your recovery — the body heals well when it is gently active
• After 1–2 weeks: Most people feel ready to return to a desk-based job. You can drive again once you are confident you could perform an emergency stop comfortably and without hesitation — for most people this is within a week or so
• For the first 1–2 weeks, avoid heavy lifting, pushing, or pulling — a useful guide is nothing heavier than about 5–10 kg (the weight of a small grocery bag), unless told otherwise. Light household tasks, sitting, and walking are fine as long as they do not cause pulling at the wound. After 1–2 weeks, heavier lifting can gradually resume as comfort allows
• After 4 weeks: Most people are easing back into manual work and moderate exercise, such as walking, swimming, and lighter gym sessions
• After 6 weeks: Most people are back to full activity, including heavier lifting and more strenuous sport
• A post-operative review is routinely arranged 2–6 weeks after your operation — this review is provided at no charge, and it is your opportunity to raise anything that has come up during your recovery
• For day-by-day guidance on wound care, activity progression, what a seroma feels like, and when to return to driving, lifting, and sport, see the Post-hernia-repair aftercare guide on the Resources page.
