1.1 Evidence on the safety and efficacy of endoscopic full thickness removal of gastrointestinal stromal tumours of the stomach is inadequate in quality and quantity. Therefore, this procedure should only be used in the context of research. Find out what only in research means on the NICE interventional procedures guidance page.
1.2 Further research should ideally be randomised controlled trials or registry studies. It should report patient selection, tumour type, size and anatomical position, and long-term outcomes (such as tumour recurrence).
1.3 Patient selection should be done by a multidisciplinary team.
1.4 This procedure should only be done in specialist centres by interventional upper gastrointestinal endoscopists with specific training in this procedure.
