Imagine surgery that could be performed without general anaesthetic, requires hardly any recovery time, and leaves you with no visible scars. The catch: it may also leave a very unpleasant taste in your mouth – along with part of your spleen, prostate or perhaps your gall bladder.
Transgastric surgery, or natural orifice translumenal endosurgery (NOTES), as it is officially known, involves passing flexible surgical tools and a camera in through the patient’s mouth to reach the abdominal cavity via an incision made in the stomach lining. Once the operation is over, the surgeon draws any removed tissue back out through the patient’s mouth and stitches up the hole in the stomach.
