Background And Study Aims:
Endoscopic full-thickness resection of gastric subepithelial tumors with a full-thickness suturing device has been described as feasible in two small case series. The aim of this study was to evaluate the efficacy, safety, and clinical outcome of this resection technique.
Patients And Methods:
After 31 patients underwent endoscopic full-thickness resection, the data were analyzed retrospectively. Before snare resection, 1 to 3 full-thickness sutures were placed underneath each tumor with a device originally designed for endoscopic anti-reflux therapy.
Results:
All tumors were resected successfully. Bleeding occurred in 12 patients (38.7 %); endoscopic hemostasis could be achieved in all cases. Perforation occurred in 3 patients (9.6 %), and all perforations could be managed endoscopically. Complete resection was histologically confirmed in 28 of 31 patients (90.3 %). Mean follow-up was 213 days (range, 1 - 1737), and no tumor recurrences were observed.
Conclusion:
Endoscopic full-thickness resection of gastric subepithelial tumors with the suturing technique described above is feasible and effective. After the resection of gastrointestinal stromal tumors (GISTs), we did not observe any recurrences during follow-up, indicating that endoscopic full-thickness resection may be an alternative to surgical resection for selected patients.
