Gastric Neoplasms, Gastrointestinal Stromal Tumors
Conditions
Brief summary
Prospective observational trial. A full thickness resection of gastric subepithelial tumors is performed after application of full thickness sutures underneath the tumor with the GERDX(TM) device. Hypothesis: This endoscopic method is feasible, effective and safe.
Interventions
Endoscopic full thickness resection of subepithelial gastric tumors using the GERDX suturing device.

Eligibility
Inclusion criteria
* presence of a subepithelial gastric tumor with signs of potential malignancy in endoscopic ultrasound * age 18 years or older * participant has given informed consent
Exclusion criteria
* tumor size \> 40 mm (endosonographic measurement) or large extramural tumor mass * signs of systemic dissemination of tumor * current presence of a different neoplastic disease (except after successful curative treatment without continued medication) * former surgery or disease of esophagus or stomach that impedes insertion of the suturing device * moribund patient * limited possibility to give informed consent (e.g. language barrier, psychiatric disease) * pregnancy and lactation period
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Rate of cases in which a complete macroscopic en bloc resection of the gastric subepithelial tumor could be achieved | intraoperative |
Secondary
| Measure | Time frame |
|---|---|
| Rate of cases in which a complete microscopic resection of the gastric subepithelial tumor could be achieved | within one week after resection (as soon as result of pathologic analysis of resected specimen is available) |
| Rate of complications (bleeding, perforation) | 6 months after resection |
| Duration of hospitalization | within one week after resection |
| Number of participants with local or systemic recidive of tumor | 6 months after resection |
