  • Gallstones

    Need to know

    Sometimes gallstones (small stones of cholesterol) develop in the gallbladder or nearby bile duct. The gallbladder is a pear-shaped organ beneath your liver.

  • Achalasia

    Need to know

    Achalasia is where the oesophagus and ring fail to contract and relax. This leads to a build up of food and stops it from entering the stomach. When you swallow food, the muscles in your oesophagus (the tube from your mouth to your stomach) contract to push it along. A valve at the end of the oesophagus...

  • Inguinal hernia repair

    Need to know

    A groin-area hernia is the most common type of hernia. It's caused by a weakness in your abdominal wall, which allows the contents of your abdomen to push through the muscle, producing a lump called a hernia. If left untreated, a hernia will not heal on its own and can cause serious complications.

  • Umbilical hernia repair

    Need to know

    An umbilical hernia occurs near the belly button (umbilicus). It is a condition caused by a weakness in the muscles of the abdominal wall. This weakness allows part of the bowel or internal tissue to push through, forming a pouch or painful bulge called a hernia. Surgery to repair a hernia and strengthen...
