Endoscopic Resection of Gastric Subepithelial Masses, EndoResect Study

Endoscopic Resection of Gastric Subepithelial Masses, EndoResect Study

Gastric subepithelial masses might harbour gastrointestinal stromal tumors, which should get resected because of their malignant potential. To minimize the associated surgical trauma endoscopic endoluminal resection is favorable. Therefore in the current study endoscopic resection of gastric subepithelial masses is investigated. Since there is a certain risk of perforation due to the procedure, perforations get closed by placement of endoscopic clips (over-the-scope-clip [OTSC] clips).

During an initial pilot phase 8 patients receive endoscopic resection under laparoscopic control. Thereafter and after positive initial results sole endoluminal endoscopy is done for a total of 38 patients.

Inclusion Criteria:

• Endosonographically suspicous gastric subepithelial mass <=3 cm.

Exclusion Criteria:

• American Society of Anesthesiologists (ASA) classes IV or V
• Pregnancy
• Bleeding disorders
• Contraindications for endoscopy
• Endosonographically shown large vessels in the area for resection
