If you have been told you need hernia surgery, one of the first questions you will face is: should it be done laparoscopically (keyhole) or open? Both techniques are well-established and both are effective — but they have meaningful differences in recovery time, pain levels, scarring, and suitability for different patients.
Understanding these differences will help you have an informed conversation with your surgeon and make the right decision for your situation.
Dr Devesh Kaushal is an upper GI and general surgeon in Liverpool who performs both laparoscopic and open hernia repair. In this guide, he explains both techniques in plain language — their advantages, limitations, and who each approach is best suited for.

How Laparoscopic (Keyhole) Hernia Repair Works
Laparoscopic hernia repair — also called keyhole or minimally invasive hernia surgery — uses small incisions (typically 5–10mm) and a tiny high-definition camera to repair the hernia without a large cut. It is performed under general anaesthesia.
Step-by-step — laparoscopic repair:
- Three small incisions (5–10mm) are made — typically one at the umbilicus and two in the lower abdomen
- A laparoscope (thin camera tube) is inserted through one incision, transmitting live images to a monitor
- Specialised instruments through the other incisions allow Dr Kaushal to work precisely inside the abdomen
- The hernia defect is identified and the hernia contents are gently reduced back into the abdomen
- A synthetic mesh is carefully positioned behind the abdominal wall to cover and reinforce the defect
- The incisions are closed with dissolvable stitches — no removal needed
Two main laparoscopic techniques for inguinal hernia:
- TEP (Totally Extraperitoneal): The repair is performed in the space behind the abdominal wall — without entering the abdominal cavity. This reduces the risk of intra-abdominal complications and is Dr Kaushal’s preferred approach for most inguinal hernias.
- TAPP (Transabdominal Preperitoneal): The abdomen is entered, the hernia is repaired from inside, and the mesh is placed behind the peritoneum. Useful when the anatomy requires a different approach or when combined with other abdominal procedures.
Key advantage: For bilateral inguinal hernias (both sides), laparoscopic repair allows both hernias to be fixed through the same three small incisions in a single operation — a major practical advantage over open repair. |
How Open Hernia Repair Works
Open hernia repair is the traditional surgical approach, used since long before laparoscopic techniques became available. It remains an important and effective option — particularly in certain clinical situations.
Step-by-step — open repair:
- A single incision is made directly over the hernia site — typically 5 to 8cm for an inguinal hernia
- The hernia contents are identified and gently pushed back into the abdomen
- A mesh is placed over the hernia defect (Lichtenstein tension-free repair — the gold standard open technique) OR in selected cases, the defect is repaired with sutures alone
- The incision is closed in layers with sutures — which may be dissolvable or require removal
Open repair can also be performed under local anaesthesia:
Unlike laparoscopic repair, open inguinal hernia repair can be performed under local anaesthetic with sedation — making it accessible to patients who cannot safely tolerate general anaesthesia. This is a significant advantage for elderly patients or those with serious cardiac or respiratory conditions.
Complete Comparison: Laparoscopic vs Open Hernia Repair
Factor | ✔ Laparoscopic (Keyhole) | Open Repair |
Incision size | 3 cuts of 5–10mm | Single cut of 5–8cm at hernia site |
Anaesthesia | General anaesthesia required | General OR local anaesthesia possible |
Post-op pain | Mild to moderate — generally less | Moderate — more wound discomfort |
Hospital stay | Day surgery — same day discharge | Day surgery or overnight |
Return to desk work | 1 – 2 weeks | 2 – 3 weeks |
Return to manual work | 4 – 6 weeks | 6 – 8 weeks |
Scarring | 3–4 small scars — fade over time | One longer scar at hernia site |
Bilateral hernias | Both sides — one operation, same cuts | Two separate incisions needed |
Recurrent hernia repair | Excellent — avoids previous scar tissue | Can be technically more difficult |
Wound infection risk | Lower — smaller wounds | Slightly higher — larger incision |
Chronic groin pain risk | Comparable to open with modern technique | Comparable to laparoscopic |
Recurrence rate | ~1–3% with mesh (comparable to open) | ~1–3% with mesh (comparable to lap) |
Recovery comfort | Generally faster, less discomfort | Longer discomfort period |
Best for | Most hernias, bilateral, recurrence | High anaesthetic risk, complex, large |
When Is Laparoscopic Hernia Repair the Preferred Choice?
For most patients presenting with an inguinal, umbilical, or small incisional hernia, laparoscopic repair offers clear advantages — and is Dr Kaushal’s recommended approach in the majority of cases.
- Bilateral inguinal hernias — both repaired through same incisions in one operation
- Recurrent inguinal hernia — laparoscopic approach avoids the scar tissue from previous open repair
- Young, active patients who want the fastest return to work and physical activity
- Patients concerned about scarring and cosmetic outcome
- Umbilical and small to medium incisional hernias — excellent laparoscopic results
- Patients who are fit for general anaesthesia
- Patients who want to minimise hospital stay
When Is Open Hernia Repair the Better Option?
Open repair remains an excellent option — and in certain clinical circumstances, it is the safer or more appropriate choice:
- High anaesthetic risk: Patients with significant cardiac, respiratory, or medical conditions who cannot safely receive general anaesthesia can undergo open repair under local anaesthetic with sedation.
- Very large or complex hernias: Exceptionally large inguinal or incisional hernias may be better approached open, where direct visualisation provides better control.
- Extensive previous lower abdominal surgery: Dense scar tissue from prior operations (particularly previous laparoscopic hernia repair, prostatectomy, or lower abdominal procedures) may make the laparoscopic space difficult to safely navigate.
- Strangulated hernia requiring emergency surgery: Emergency hernia repair for strangulation or incarceration is often best performed open for speed, safety, and direct access.
- Patient preference: Some patients, after being fully informed of both options, prefer an open repair. This preference is respected and accommodated.
Choosing the right approach is not always straightforward. It requires a thorough assessment of the hernia type, size, complexity, previous surgical history, medical fitness, and patient preferences. Dr Kaushal will recommend the approach most appropriate for your individual situation — and explain clearly why. |

Hernia Mesh Surgery: Everything You Need to Know
Hernia mesh is used in the vast majority of hernia repairs today — both laparoscopic and open. It has transformed the outcomes of hernia surgery by dramatically reducing recurrence rates. Understanding mesh, its benefits, and its risks is an important part of making an informed surgical decision.
What is hernia mesh?
Hernia mesh is a synthetic fabric — most commonly made from polypropylene — that is placed over or behind the hernia defect to reinforce the weakened abdominal wall. Over time, the body’s own fibrous tissue grows into the mesh, creating a strong, durable repair that is significantly more resistant to recurrence than suture-alone techniques.
Types of mesh used in hernia repair:
Mesh Type | Weight | Typical Use |
Lightweight polypropylene | Low | Most laparoscopic inguinal repairs — minimises foreign body sensation |
Heavyweight polypropylene | Higher | Open repair (Lichtenstein) — well-established long-term record |
Composite / coated mesh | Low | Repairs adjacent to bowel — anti-adhesion coating on inner surface |
Biological mesh | N/A | Infected fields, contaminated repairs — absorbed over time |
Self-fixing / tack-free | Low | Laparoscopic — sticks in place without fixation devices |
Mesh and chronic pain — addressing a common concern:
Chronic post-hernia repair pain (also called inguinodynia) is one of the most significant quality-of-life issues following hernia surgery — occurring in approximately 10–15% of patients to some degree. Importantly, most chronic pain after hernia repair is not caused by mesh itself, but by nerve handling during surgery.
Modern lightweight mesh and careful nerve-sparing technique — which Dr Kaushal employs — significantly reduce the risk of chronic pain compared to older techniques and heavier mesh materials. The risk of mesh-specific complications such as migration or infection is low with modern materials and correct surgical technique.
Can hernia be repaired without mesh?
In very selected cases — small umbilical or epigastric hernias, or patients with documented mesh intolerance — primary suture repair without mesh can be considered. However, recurrence rates are significantly higher without mesh, and this approach is only appropriate in carefully selected circumstances. Dr Kaushal will advise you honestly on the trade-offs.
Laparoscopic Hernia Repair Techniques Explained
TEP — Totally Extraperitoneal
In TEP repair, the surgery is performed entirely in the space between the abdominal wall and the peritoneum (the membrane lining the abdominal cavity), without entering the abdominal cavity itself. This approach avoids the risks associated with entering the peritoneum — such as bowel or bladder injury — and has become the preferred laparoscopic technique for most inguinal hernias.
TAPP — Transabdominal Preperitoneal
In TAPP repair, the abdomen is entered through the peritoneum, the hernia is repaired, mesh is placed behind the peritoneum, and the peritoneum is then closed over the mesh. This approach provides a wider view of the anatomy and is useful when the anatomy is complex, when combined procedures are needed, or when TEP is technically difficult.
Which technique will Dr Kaushal use? Dr Kaushal selects the most appropriate laparoscopic technique based on your specific anatomy, hernia characteristics, and surgical history. Both TEP and TAPP produce excellent results in experienced hands — technique choice is a surgical decision, not a patient preference question. Dr Kaushal will explain the planned approach at your consultation. |

Frequently Asked Questions
Is laparoscopic hernia repair better than open?
For most patients with straightforward inguinal hernias — especially bilateral or recurrent hernias — laparoscopic repair offers meaningful advantages: less post-operative pain, faster return to normal activities, and smaller scars. For patients who cannot have general anaesthesia, or those with very complex anatomy, open repair may be the safer choice. Both techniques produce similar long-term recurrence rates with mesh.
Will I be awake during hernia surgery?
Laparoscopic hernia repair requires general anaesthesia — you will be completely asleep. Open hernia repair can be performed under local anaesthetic with sedation — meaning you are awake but comfortable and pain-free. The choice of anaesthetic is based on the surgical approach and your medical suitability.
Is hernia mesh safe?
Modern lightweight hernia mesh has an excellent safety profile and is the globally recognised standard of care for hernia repair. Serious mesh-related complications — such as infection, migration, or severe chronic pain — are uncommon with modern materials and correct surgical technique. Mesh has dramatically reduced hernia recurrence rates compared to suture-only repair. Dr Kaushal discusses mesh use and any specific concerns at your consultation.
How long does keyhole hernia surgery take?
Laparoscopic inguinal hernia repair typically takes 45 to 75 minutes for a single-sided repair and 75 to 90 minutes for bilateral repair. The total time at hospital on the day of surgery is approximately 4 to 6 hours, including admission, preparation, the procedure, and recovery.
Can I have laparoscopic repair if I have had previous abdominal surgery?
This depends on the nature and location of your previous surgery. Some previous abdominal procedures — particularly previous laparoscopic hernia repair on the same side, or major lower abdominal surgery such as prostatectomy — can make laparoscopic repair more technically challenging. Dr Kaushal reviews all previous surgical history at consultation and recommends the safest and most appropriate approach for your specific situation.
