The National Institute for Health and Clinical Excellence (NICE) has issued full guidance to the NHS in England, Wales, Scotland and Northern Ireland on Endoscopic submucosal dissection (ESD) of gastric lesions.


This procedure can be used to treat abnormalities on the wall of the stomach. A long camera (endoscope) is inserted through the oesophagus and into the stomach to view the affected area. A solution is injected into the wall of the stomach, and then the part of the stomach wall that looks abnormal is removed with special instruments. The aim of the procedure is to help avoid the need for open surgery, and to obtain a good quality sample for examination under the microscope.
