Inguinal Hernia Repair (Laparoscopic, Robotic & Open)

An inguinal hernia happens when abdominal contents, usually fat or a loop of intestine, push through a weak spot in the groin muscles. It typically appears as a bulge that gets bigger when standing, coughing, or lifting, and it may cause aching, burning, or heaviness.

Inguinal hernias are extremely common:

• Lifetime risk of surgery: about 27% in men and 3% in women (Rancke-Madsen et al., Cochrane Database of Systematic Reviews, 2026)

• Worldwide volume: more than 20 million groin hernia repairs every year (HerniaSurge Group, Hernia, 2018)

• Surgery is the only cure. Hernias don't heal on their own, and trusses or binders don't repair the defect.

Modern repair uses a mesh to reinforce the weakened area, which lowers recurrence compared with stitch-only repairs (HerniaSurge Group, Hernia, 2018). The international HerniaSurge guidelines recommend a laparoscopic technique for primary unilateral hernias when a surgeon with specific expertise is available. That recommendation reflects less chronic pain and faster recovery (Rosenberg et al., Nature Reviews Disease Primers, 2025).

The three most common mesh techniques are (Rancke-Madsen et al., Cochrane Database of Systematic Reviews, 2026):

• Open Lichtenstein repair, through a groin incision

• Laparoscopic TAPP (transabdominal preperitoneal) repair

• Laparoscopic TEP (totally extraperitoneal) repair

Robotic-assisted TAPP is a variation of the laparoscopic approach.

‍

• The weak area. The groin has three potential hernia sites: indirect, direct, and femoral. Together they're called the myopectineal orifice.

• Laparoscopic and robotic repair (posterior approach). The surgeon works from behind the abdominal wall and places a mesh in the preperitoneal space, between the muscles and the abdominal lining. All three hernia sites are covered at once (Rosenberg et al., Nature Reviews Disease Primers, 2025).

• Both sides are seen. The camera shows both groins through the same incisions. Hidden (occult) hernias on the other side are found in about 10–25% of patients having a one-sided repair (Morais et al., Hernia, 2026).

• Open Lichtenstein repair (anterior approach). The mesh is placed from the front, through a groin incision of about 5–6 cm. It can be done under local anesthesia and has lower initial costs (Fitzgibbons and Forse, New England Journal of Medicine, 2015).

• Mesh becomes part of the abdominal wall. Tissue grows into the mesh over the following weeks, creating a tension-free reinforcement.

‍

• Less chronic groin pain. Compared with Lichtenstein repair, chronic pain was 64% lower with TAPP and with TEP (risk ratio 0.36) in a 35-trial network meta-analysis (Aiolfi et al., Annals of Surgery, 2021). Overviews of systematic reviews consistently show about half the odds of chronic pain after laparoscopic repair (Haladu et al., Surgical Endoscopy, 2022).

• Faster return to work and activity: about 3–4 days sooner than open repair (Aiolfi et al., Annals of Surgery, 2021).
• Fewer wound problems. In a 2026 meta-analysis, TAPP lowered (Butt et al., Surgery, 2026):
  • Surgical site infection: risk ratio 0.36
  • Hematoma: risk ratio 0.27

• Low recurrence. With mesh, recurrence is about 1.8%, vs 4.0% for non-mesh repair (Meuzelaar et al., Hernia, 2025).

• Both sides fixed through the same incisions when bilateral hernias are present (Rosenberg et al., Nature Reviews Disease Primers, 2025).

• Femoral hernias aren't missed, which matters most for women (Silveira et al., Surgical Endoscopy, 2024).

• Relief of pain and activity limits, and removal of the small but real risk of incarceration and strangulation.

‍

• Men with symptomatic inguinal hernias. Repair is recommended for hernias causing pain, discomfort, or activity limits (HerniaSurge Group, Hernia, 2018).
• Men with no or minimal symptoms. Watchful waiting is safe, but most eventually need surgery (Fitzgibbons and Forse, New England Journal of Medicine, 2015; HerniaSurge Group, Hernia, 2018):
  • About 70% cross over to surgery within 5 years, mostly because of pain.
  • 68–72% had surgery by 7.5–10 years in the two major randomized trials.
  • Delaying surgery didn't increase complications when surgery was eventually done.

• All women with groin hernias. Timely repair is recommended. Women have a higher risk of femoral hernia and emergencies, and about 17% of women with groin hernias need emergency repair (HerniaSurge Group, Hernia, 2018).

• Bilateral or recurrent hernias. Laparoscopic repair is especially useful: both sides through one set of incisions, or a fresh, unscarred plane after a prior open repair (Shakil et al., American Family Physician, 2020).

• Athletes and active patients who want the fastest return to training.

• Older adults or high-risk patients who may benefit from open repair under local anesthesia (Fitzgibbons and Forse, New England Journal of Medicine, 2015).

Emergency surgery is needed for a hernia that becomes stuck, painful, red, or tender, or that comes with nausea, vomiting, or inability to pass gas. These are signs of incarceration or strangulation.

‍

Laparoscopic TAPP or robotic TAPP:

1. General anesthesia.
2. Three small incisions, usually 5–12 mm.
3. Inspection of both groins through the abdomen.
4. A peritoneal flap is opened and the hernia sac is reduced back into the abdomen.
5. The entire myopectineal orifice is exposed, including the indirect, direct, and femoral spaces.
6. A large mesh is placed to cover all three sites.
7. The peritoneal flap is closed over the mesh.

Laparoscopic TEP: the same repair, but done entirely in the preperitoneal space without entering the abdomen (Rancke-Madsen et al., Cochrane Database of Systematic Reviews, 2026).

Open Lichtenstein repair: a groin incision, reduction of the hernia, and mesh fixation to the floor of the inguinal canal. It's often done under local anesthesia with sedation.

Mesh fixation is tailored. Many laparoscopic repairs need little or no fixation, while fixation is considered for large direct defects over 3 cm and large bilateral hernias (Meuzelaar et al., Hernia, 2025).

Typical operating time is about 30–90 minutes, depending on the technique and whether one or both sides are repaired.

‍

• Overall, modern hernia repair is very safe. Serious adverse events are rare (Rosenberg et al., Nature Reviews Disease Primers, 2025).

• Seroma or hematoma. These are fluid or blood collections in the groin or scrotum. They're the most common early issue and usually resolve on their own (Rosenberg et al., Nature Reviews Disease Primers, 2025).

• Urinary retention right after surgery, usually temporary.
• Chronic groin pain, meaning pain lasting more than 3 months:
  • Overall: about 10–12% of patients (Rancke-Madsen et al., Cochrane Database of Systematic Reviews, 2026)
  • After laparoscopic repair: about half the risk of Lichtenstein repair
  • Moderate or severe chronic pain: about 3% in randomized trials, similar with or without mesh (Öberg et al., Surgery, 2018)

• Recurrence: about 2–3% overall in practice (Rosenberg et al., Nature Reviews Disease Primers, 2025). Reoperation for recurrence was around 5% at 5 years after both open and laparoscopic repair (Rancke-Madsen et al., Cochrane Database of Systematic Reviews, 2026).

• Mesh infection. It's uncommon, but it may require antibiotics, drainage, or rarely mesh removal (Rosenberg et al., Nature Reviews Disease Primers, 2025).

• Injury to bowel, bladder, or blood vessels. These are rare, slightly more possible with TAPP because the abdomen is entered (Rosenberg et al., Nature Reviews Disease Primers, 2025; Shakil et al., American Family Physician, 2020).

• Testicular complications, such as swelling or, rarely, reduced blood flow.

• Anesthesia risks. Laparoscopic repair routinely requires general anesthesia (Fitzgibbons and Forse, New England Journal of Medicine, 2015).

‍

• Most patients go home the same day.

• Daily activities: walking and light household tasks immediately (Rosenberg et al., Hernia, 2025).

• Return to work and leisure: HerniaSurge found no need for activity restrictions after uncomplicated repair, with return to activities in about 3–5 days (Schaaf et al., Hernia, 2022).

• Strenuous exercise and contact sports: generally avoided for the first 2–4 weeks (Rosenberg et al., Hernia, 2025).

• Heavy lifting: leading hernia surgeons recommended a median of 14 days after Lichtenstein and 21 days after laparoscopic repair (Harmankaya et al., Surgical Endoscopy, 2023). There's no evidence that early activity increases recurrence (Schaaf et al., Hernia, 2022).

• Pain control: mostly non-opioid medication and ice.

• Driving once off narcotic pain medication and able to brake comfortably.

‍

• Durable repair for most patients. Recurrence is about 2–3% with standardized mesh techniques (Rosenberg et al., Nature Reviews Disease Primers, 2025).

• Large improvements in pain, function, and quality of life, usually evident by 6 weeks and sustained at 1 year (Mommers et al., Hernia, 2017).

• A new hernia on the other side can develop later. It occurred in about 8.3% of patients after one-sided repair in a meta-analysis (Vissers et al., Surgical Endoscopy, 2024). That's one reason both sides are inspected during laparoscopic repair.

• Modifiable risks for recurrence include obesity, smoking, and chronic cough (Rosenberg et al., Nature Reviews Disease Primers, 2025).
