ENDOSCOPIC TUNNELING AND SUB-SEROSAL DISSECTION (ETSSD) USING NOTES APPROACH FOR GASTRIC GASTROINTESTINAL STROMAL TUMOR (GIST)

Video Transcription

Video Summary

The video details a novel endoscopic technique for resecting exophytic gastric subepithelial tumors in a 74-year-old female patient. The method involves submucosal tunneling and full-thickness myotomy to access the peritoneal cavity, allowing the lesion to be approached from the serosal side. Adhesions were dissected, and the tumor was carefully resected using a snare and clip method to prevent tumor spillage. After resection, the mucosal defect was sutured endoscopically. The patient previously received imatinib to reduce tumor size, facilitating this minimally invasive approach. The procedure proved safe and effective, with minimal complications such as bleeding or tumor seeding.
