Brief summary
To analyse the effectiveness and safety of endoscopic band ligation without resection in small gastrointestinal subepithelial tumours.
Detailed description
Multicenter prospective study analysing the effectiveness and safety of endoscopic band ligation without resection in small (≤15-mm) gastrointestinal subepithelial tumours. This endoscopic technique will be complemented with a SINK (single-incision needle-knife) biopsy for ensuring the pathological diagnosis of the treated subepithelial tumour.
Interventions
Endoscopic treatment of subepithelial tumors: autoamputation by endoscopic band ligation without resection.
To obtain sample tissue biopsies after the endoscopic band ligation without resection, performing a single-incision with a needle-knife.

Eligibility
Inclusion criteria
* Age between 18 and 80 years old. * Endoscopic ultrasound (EUS) image of a gastrointestinal subepithelial tumour (SET) ≤15-mm. * Patient capable of understanding and signing informed consent form. * Patient understanding the type of study and complying with the follow-up of complementary tests during the study duration.
Exclusion criteria
* SETs \>15-mm. * SETs with clear diagnosis of EUS benign semiology: ie., lipoma, ectopic pancreas. * Patients with multiple SETs (e.g., carcinoids). * Vascular SETs (Doppler effect by EUS). * Severe coagulation disorder: INR \>1.5 not correctible with administration of plasma and/or platelets \<50,000/mm3. * Conditions that preclude upper digestive endoscopy, such as stenosis. * Pregnancy or breast-feeding. * Failure to sign informed consent form. * Patients with functional diversity who are unable to understand the nature and possible consequences of the study, unless there is a competent legal representative. * Patients unable to adhere to subsequent follow-up requirements. * Patients with a life expectancy of less than 12 months.
