An inguinal hernia repair is surgery for a lump in the groin caused by tissue or part of the bowel pushing through a weak spot. It may be done if the hernia is causing pain or to stop it causing a blocked or strangulated bowel. A hernia that is not causing symptoms may not need treatment.
The operation is done either by keyhole (laparoscopic) surgery or by open surgery, under general or local anaesthetic. Hospital-level numbers for this operation are not published as open data, so this page shows NHS waiting times for general surgery.
London hospitals
21 London trusts with published figures. Sorted by name. This is not a ranking: read how to read this first.
Hospital-level numbers for this specific operation are not published as open data. The activity column is context only: it shows the trust's overall NHS-funded activity in OPCS-4 chapter T (soft tissue (including hernias)) in 2025-26, from Hospital Episode Statistics, in bands. It covers many other procedures as well as this one, it is for the whole trust rather than one hospital, and it does not include private patients. It is not a count of this operation.

Across England
In 2025-26, NHS-funded care in England (NHS hospitals and NHS patients treated by independent providers; private patients are not included) recorded 64,050 episodes where the main procedure was primary repair of inguinal hernia (OPCS-4 T20). 75% were day cases. Half of the people admitted from a waiting list had waited less than about 95 days from the decision to admit them. These are national figures from Hospital Episode Statistics (NHS England, 2025-26, Open Government Licence v3.0); the same detail is not published for each hospital.
How to read this
- Not a ranking. The table is in alphabetical order. A higher volume does not on its own mean better care, and we do not combine the columns into a score.
- Trust activity (Hospital Episode Statistics). The bands show the trust’s overall NHS-funded activity in a whole chapter of the procedure classification (OPCS-4), for context. They are not a count of this operation, they are for the whole trust rather than one hospital, they exclude private patients, and we show bands only, not exact counts. Cut points are the lower quartile, median and upper quartile of all 136 NHS trusts in England with activity in OPCS-4 chapter T in the published table, rounded.
- Risk adjustment. Where a figure says “adjusted”, the audit has allowed for differences in the patients each hospital treats, such as age and other illnesses. Hospitals that take on more complex cases can still look different for reasons the adjustment does not capture.
- Bands and limits. We only say a result is higher or lower than expected when the source itself says so (for example NJR outlier status, NELA funnel limits, SSNAP levels, CQC survey bands). Where the source publishes a rate without limits we show the rate and the national figure, and say “No banding published”.
- Small numbers. A small hospital can have 0% or a high percentage by chance. Figures the source suppresses are shown as “Not published (small numbers)”.
- Trust or hospital. This audit publishes figures for each NHS trust, which may run several hospitals. The operation may only be done at one of them.
- Different periods. Each figure has its own period, shown next to it. Audit results describe operations done one to three years ago; waiting times are updated monthly.
- Talk to your GP or consultant about what the figures mean for you. If you are referred for planned care in England, you can usually choose your hospital.
