## Description

Laparoscopic hernia repair is a minimally invasive technique in which the hernia defect is approached from inside the abdominal wall using small ports and a camera, with mesh placed in the preperitoneal space to reinforce the defect. The two main variants are transabdominal preperitoneal (TAPP) repair, which enters the abdominal cavity, and totally extraperitoneal (TEP) repair, which dissects the preperitoneal space without entering the peritoneum. Compared to open repair, laparoscopic approaches offer faster return to normal activity, lower acute pain, and better cosmesis — at the cost of a longer operative time, the requirement for general anaesthesia, and a steeper learning curve for the surgeon.

## Overview

Laparoscopic hernia repair is a minimally invasive operation to repair an inguinal hernia — a weakness or defect in the lower abdominal wall that allows fatty tissue or part of the small intestine to slip into the inguinal canal in the groin. Inguinal hernias are the most common type of hernia, accounting for about 75% of all hernia surgery cases in the US, and are far more common in men, who make up around 90% of cases. A hernia may be asymptomatic, or it may become incarcerated (unable to be pushed back) or strangulated, in which the blood supply to the trapped tissue is cut off. Typical symptoms include a groin lump that appears on standing or straining and disappears on lying down, along with aching or pressure that is often worst at the end of the day or after exertion. The decision to operate is guided by symptom severity, the type and size of the hernia, whether the bowel is incarcerated, and the person's general health; a strangulated hernia is a surgical emergency, and repair within about six hours may save the affected intestine. In a laparoscopic approach the defect is reached through small ports using a camera, and mesh reinforces the weakened area. This route requires general anaesthesia and may be unsuitable for people who cannot undergo it, or who have had major open abdominal surgery, ascites, previous pelvic radiation, or a complex hernia.

## FAQs

### Is laparoscopic better than open hernia repair?

For bilateral and recurrent inguinal hernias, NICE TA160 recommends laparoscopic repair as the preferred approach. For primary unilateral hernias, the choice depends on surgeon experience and patient preference; recurrence rates are comparable but chronic post-operative pain is lower with laparoscopic in experienced hands.

### What is the difference between TAPP and TEP?

TAPP (transabdominal preperitoneal) enters the abdominal cavity, then dissects the preperitoneal space from inside. TEP (totally extraperitoneal) dissects the preperitoneal space from outside without entering the peritoneum. Outcomes are broadly similar; the choice usually depends on surgeon training and preference.

### Can laparoscopic repair be done under local anaesthesia?

No — laparoscopic hernia repair requires general anaesthesia due to the need for muscle relaxation and pneumoperitoneum. Open repair can sometimes be done under local anaesthesia in selected patients.

### How long until I can fly home?

Most surgeons permit flying 3-5 days after uncomplicated laparoscopic repair. DVT prophylaxis per IATA medical guidance is recommended for long-haul flights.

### What is the recurrence rate?

In experienced hands, recurrence rates for laparoscopic primary inguinal hernia repair are 1-3%. Recurrence rates rise significantly with low-volume surgeons or complex cases. The Cochrane review of open vs laparoscopic mesh repair shows comparable overall recurrence rates between approaches in adequately powered studies.

### Will I have visible scars?

Three small port-site scars, each approximately 5-10mm long, typically placed in the umbilicus and the lower abdomen. These usually fade to near-invisibility within 6-12 months.

### Can I have laparoscopic repair if I have had previous abdominal surgery?

Previous abdominal surgery is not an absolute contraindication but may make laparoscopic dissection more difficult due to adhesions. The surgeon may convert to open repair intra-operatively if access is unsafe. Discuss your previous surgery in detail at the pre-operative consultation.

### Can I have laparoscopic hernia repair if I have had previous abdominal surgery?

Previous abdominal surgery is not an absolute contraindication, but extensive adhesions can make laparoscopic access more difficult. The TEP variant (totally extraperitoneal) is sometimes preferred over TAPP in this situation because it avoids entering the abdominal cavity. The surgeon may convert to open repair intra-operatively if safe laparoscopic access is not achievable.

### What is the difference between TAPP and TEP in clinical outcome?

TAPP and TEP have broadly comparable long-term outcomes (recurrence, chronic pain) in adequately powered trials. TAPP allows inspection of the contralateral side and the abdominal cavity, which can reveal occult hernias; TEP avoids peritoneal entry, reducing the rare risk of bowel injury. The choice usually depends on surgeon training and patient anatomy.
