Overview

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 an excellent track record over many decades, and the results speak for themselves. 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. Mr Nguyen will gently ease the herniated tissue back to where it belongs, and then lay a flat mesh patch over the weak spot to prevent it from ever 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 an excellent, proven 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.

Who needs this procedure?

  • 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 an excellent and practical alternative that removes that concern entirely
  • You've thought about keyhole surgery but prefer the open approach — that's a perfectly valid choice, and Mr Nguyen will support whatever you decide together
  • 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

Benefits

  • 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 an excellent, well-documented safety record — you can feel genuinely confident in it
  • 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 your surgical team will be completely familiar and comfortable with every step
  • 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

Risks & considerations

  • Long-term groin discomfort — this is the most important thing to understand about open repair, and Mr Nguyen will be honest with you about it. 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. This is the main reason keyhole repair tends to be preferred when circumstances allow — it carries a lower rate of this. That said, for many people the open approach is still the right operation, and Mr Nguyen will talk through what applies to your specific situation
  • 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; slightly higher than 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). Mr Nguyen will talk you through the actual likelihood in your individual case
  • 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, call us before worrying — it's very likely just this

Before the procedure

For Mr Nguyen’s patients only. These instructions are intended solely for patients who have been seen by Mr Ba Nguyen and have been specifically directed to use them. If you are not a current patient of Mr Nguyen, please do not follow these instructions — consult your own treating doctor instead.
Fasting & medication instructions

Food: You may eat up until 6 hours before your admission time, then fast completely. Do not eat anything after this point — your procedure may be cancelled if you do.

Clear fluids: You may drink clear fluids up until 2 hours before your admission time. Clear fluids include: water (still or sparkling), cordial, sports drinks, lemonade, pulp-free apple juice, black tea or coffee, clear broth. Avoid red or purple coloured drinks.

Medications: Continue all regular medications as usual, taken with a small sip of water. Do not chew gum on the day of your procedure.

Supplements: Stop all non-prescribed vitamins, minerals, and herbal supplements (including fish oil, glucosamine, and vitamin E) at least 5 days before your procedure. Also stop iron supplements at least 7 days before.

Blood thinners: If you take warfarin, rivaroxaban (Xarelto), apixaban (Eliquis), dabigatran (Pradaxa) or clopidogrel, contact Mr Nguyen’s rooms for specific advice — these may need to be stopped or bridged before your procedure.

Diabetes medications: If you take oral or injectable diabetic medications (e.g. Metformin, Diamicron, Jardiance, Forxiga), stop these 2 days before your procedure. Do not stop insulin — contact our rooms for personalised dose adjustment instructions.

Weight loss injectables (GLP-1 agonists): If you take semaglutide (Ozempic, Wegovy), liraglutide (Saxenda), dulaglutide (Trulicity), or similar medications, remain on clear fluids for the full 24 hours prior to your admission time. You do not need to stop your medication. Please inform Mr Nguyen’s rooms when booking.

  • No bowel preparation is needed — you don't need to take laxatives or do anything special to prepare your bowels beforehand
  • Before your operation, Mr Nguyen will sit down with you to go through the mesh (what it is and why it's used), the possibility of some ongoing groin sensitivity, and the nerve anatomy involved — so that you can ask anything you want and sign your consent form feeling genuinely comfortable and informed, not just rushed through the paperwork
  • 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

On the day

  • You'll receive the type of anaesthetic that was 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're awake), or general (you're fully asleep and completely unaware of anything). All three are safe and effective options
  • Mr Nguyen makes a single incision 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'll 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'll feel confident rather than uncertain when you get through your front door

Recovery & aftercare

  • 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 like ibuprofen if that's safe for you. Take it easy, accept help, and don't try to rush yourself
  • Days 3–5: You'll start to feel noticeably more like yourself. Gentle movement around the house is fine and is actually beneficial for your recovery — your body heals well when it's gently active
  • After 1–2 weeks: Most people feel ready to return to a desk-based job. You can drive again once you're confident you could perform an emergency stop comfortably and without hesitation — for most people this is within a week or so
  • After 4 weeks: You can ease back into manual work and moderate exercise, such as walking, swimming, and lighter gym sessions
  • After 6 weeks: You should be able to return to full activity, including heavier lifting and more strenuous sport
  • For the first 4 weeks, please avoid straining and don't lift anything heavier than about 10 kg — this is genuinely important. It gives the mesh time to bond and the repair time to fully strengthen
  • A follow-up appointment with Mr Nguyen is routinely scheduled 2–6 weeks after your operation — this review is provided at no charge, and it's your opportunity to raise anything that has come up during your recovery
