Open Mesh Inguinal Hernia Repair Surgery in Jaipur

What is open mesh inguinal hernia repair

Open mesh inguinal hernia repair uses the Lichtenstein tension-free technique, which is the most widely applied open method for primary inguinal hernias in adults. The operation places a flat polypropylene mesh behind the floor of the inguinal canal to reinforce the weak area without pulling the patient's own tissues together under tension. International guidelines recommend this approach as the preferred open technique for primary unilateral inguinal hernias.

The mesh is usually a lightweight or medium-weight macroporous polypropylene sheet measuring about 7.5 cm by 15 cm. It is shaped to extend 2 cm beyond the pubic tubercle medially and 3 to 4 cm beyond the internal ring laterally, with a slit that allows the two tails to wrap around the spermatic cord and recreate the internal ring.

The mesh lies slightly relaxed so that when the abdominal muscles contract during effort, they press the mesh more firmly against the inguinal floor.

Surgeons identify and protect the three main inguinal nerves — the ilioinguinal, iliohypogastric and the genital branch of the genitofemoral nerve — during the dissection. Meticulous nerve preservation and limited fixation are key to minimising chronic pain.

The medial edge of the mesh is secured with absorbable stitches to the rectus sheath and the internal oblique aponeurosis, while the lower edge is fixed to the inguinal ligament with a continuous non-absorbable suture. Fixation stitches are placed parallel to the iliohypogastric nerve and tied loosely to reduce the risk of nerve entrapment.

Who is suitable for this operation

The Lichtenstein repair is indicated for primary reducible inguinal hernias, whether direct or indirect, in adults. It is the preferred open approach when laparoscopic repair is not suitable.

This includes patients with significant comorbidities who may not tolerate general anaesthesia, those with previous lower abdominal or pelvic surgery that makes keyhole access difficult, and situations where laparoscopic expertise or equipment is not available. Patient preference for an open operation is also a valid indication.

Local anaesthesia is a particular advantage of this technique, making it a good choice for elderly or high-risk patients who benefit from avoiding spinal or general anaesthesia. The repair can also be performed under spinal or general anaesthesia depending on the patient's condition and the surgeon's assessment.

Relative contraindications include incarcerated or strangulated hernias that need urgent exploration, active groin infection or systemic sepsis, patient refusal of synthetic mesh, and extensive lower abdominal scarring. In female patients, the surgeon will exclude a femoral hernia during the operation by opening the transversalis fascia to inspect the femoral canal.

Anaesthesia options for open repair

Three anaesthesia options are available for Lichtenstein repair: local anaesthesia with light sedation, spinal (regional) anaesthesia, and general anaesthesia. Local anaesthesia with sedation is the classic approach for this operation and is excellent for most patients. It allows real-time feedback from the patient, provides excellent muscle relaxation for visualisation, and avoids airway manipulation.

Spinal anaesthesia is a standard alternative when the patient or surgeon prefers a regional block.

General anaesthesia is used when local or spinal anaesthesia is not appropriate, such as for:

• Very anxious patients
• Those who cannot lie flat for the duration
• When the hernia is large and the operation may take longer

The choice depends on the patient's overall health, the size and complexity of the hernia, and the preference of the anaesthetist and surgical team. Your surgeon and anaesthetist will discuss the most suitable option with you before the operation. The hospital's anaesthesia department follows standard protocols for monitoring and safety regardless of the method chosen.

Step-by-step procedure

The operation begins with a 4 to 6 cm transverse or oblique incision centred over the inguinal canal, 1 to 2 cm above the pubic symphysis and medial to the inguinal ligament. Local anaesthetic is injected beneath the external oblique aponeurosis to hydrodissect the canal, anaesthetise the inguinal nerves and protect the cord structures. The external oblique aponeurosis is then incised along its fibres from the superficial ring laterally.

The ilioinguinal nerve and the spermatic cord structures are identified early and preserved. The cord is separated from the inguinal ligament laterally up to the pubic tubercle, preserving the cremasteric sheath. The external spermatic vein within the cremasteric envelope marks the nearby genital branch of the genitofemoral nerve.

Medially, the cord is freed from the pubic tubercle by sweeping from the conjoined tendon towards the tubercle. Dissection is done with instruments, not digitally, to avoid disrupting cremasteric fibres or injuring the genital nerve or vas deferens.

For an indirect hernia, the sac is dissected to the internal ring. Narrow-neck sacs are ligated high and inverted; thick-walled sacs are resected and closed securely. The transversalis fascia is not routinely opened; it may be imbricated with absorbable suture to flatten the canal floor and reduce dead space.

A standard lightweight mesh (about 12 x 7 cm) is tailored, slit laterally, and positioned with adequate overlap. The lateral edge is fixed to the inguinal ligament with a continuous non-absorbable suture, avoiding deep bites near the femoral vessels. The medial edge is secured with absorbable sutures to the conjoint tendon.

The slit tails are reapproximated around the cord with a single U-stitch to form a snug but not constrictive new internal ring. The external oblique aponeurosis is closed with a running absorbable suture. Prophylactic antibiotics are given as a single preoperative dose per institutional protocol.

Recovery timeline and activity restrictions

After open mesh repair, most people go home the same day or stay one night in hospital. You will be encouraged to walk as soon as the anaesthesia wears off, usually within a few hours. Mild pain is managed with simple analgesics such as paracetamol or ibuprofen.

You can return to desk work or light daily activities in about 1 to 2 weeks. Studies show that patients having Lichtenstein repair took an average of 18.4 days to resume normal daily activities, compared with 13.9 days for laparoscopic repair.

Avoid heavy lifting, strenuous exercise or straining for 4 to 6 weeks. This allows the mesh to become firmly incorporated into the tissues. Your surgeon will advise when it is safe to resume specific activities based on your progress.

Follow-up visits are usually scheduled at 1 to 2 weeks and again at 6 to 12 weeks after surgery. At these visits the surgeon checks wound healing and looks for any early signs of recurrence.

Watch for:

• Excessive swelling
• Redness
• Wound drainage
• Fever
• Persistent pain that does not improve with simple painkillers

Contact the hospital or your surgeon promptly if any of these occur.

Risks and complications

Short-term complications after open mesh repair are generally uncommon. Seroma (fluid collection) and haematoma (blood collection) can occur but usually resolve without further treatment. Wound infection rates are low; no study reported deep wound infection or mesh infection in the compared trials.

Chronic pain lasting more than three months (post-herniorrhaphy neuralgia) is a recognised long-term risk. In studies, the incidence of chronic pain after Lichtenstein repair was around 21.5%, compared with 9.2% after laparoscopic repair.

Numbness or altered sensation in the groin or upper thigh can happen because small nerves may be bruised or caught during mesh fixation. Impairment of inguinal sensibility was reported in about 22% of Lichtenstein patients versus 1% after TEP repair.

Recurrence rates for Lichtenstein repair are consistently low, generally less than 1–5% in experienced hands. Long-term data show comparable reoperation risks between open and keyhole approaches for primary hernias.

Mesh infection is rare but serious; if it occurs it may need antibiotics or, very rarely, mesh removal.

Other rare complications include:

• Urinary retention
• Testicular atrophy
• Mesh migration

Open repair compared with laparoscopic repair

Operation time for open Lichtenstein repair is typically shorter than for laparoscopic (TEP or TAPP) repair. Meta-analyses report mean durations around 32–39 minutes for open versus longer times for keyhole, especially during a surgeon's learning curve.

Acute postoperative pain is significantly less after laparoscopic repair. Patients having keyhole surgery used 42% fewer analgesics in the first 48 hours and had lower pain scores at discharge and at 7 days.

Recovery to normal daily activities is faster with laparoscopy: an average of 13.9 days versus 18.4 days for open repair. Return to work is also earlier by about 3 to 4 days on average.

Chronic pain rates are consistently lower after laparoscopic repair. At 12 months, disabling complications (pain, numbness, discomfort) were significantly less after keyhole surgery; at 5 years the difference remained significant.

Recurrence rates are similar between the two techniques when performed by experienced surgeons. Large trials and registry data show no statistically significant difference in long-term recurrence.

Cost of open repair in Jaipur typically falls in the range of ₹45,000 to ₹80,000, while laparoscopic repair ranges from ₹60,000 to ₹1,20,000. The final bill depends on mesh type, hospital stay and any comorbidities.

When to see your surgeon and what to ask

Contact your surgeon or visit the emergency department if you develop any of the following after discharge:

• Increasing wound redness, swelling or discharge
• Fever above 38°C
• Sudden severe pain not relieved by prescribed tablets
• Inability to pass urine
• A new lump in the groin

These may signal infection, haematoma, urinary retention or early recurrence.

At your pre-operative consultation, ask your surgeon which anaesthesia option (local, spinal or general) is most suitable for you and why. Local anaesthesia with light sedation is the classic Lichtenstein approach and avoids airway manipulation, which can be advantageous for elderly or high-risk patients.

Ask about the type of mesh that will be used. Lightweight, large-pore polypropylene mesh is associated with less inflammation and foreign-body sensation. Your surgeon can explain the specific mesh chosen for your case.

Discuss how the nerves in the groin will be identified and protected during the operation. Meticulous nerve preservation and limited fixation (such as glue or self-gripping mesh) reduce the risk of chronic pain and numbness.

Clarify the expected timeline for returning to your usual work and activities, and when you should attend follow-up visits. Understanding the plan helps you arrange support at home and time off work.
