A HIDDEN CHALLENGE TWO NOVEL ENDOSCOPIC TECHNIQUES TO RESECT GASTRIC EXOPHYTIC SUBEPITHELIAL LESIONS

Video Transcription

Video Summary

This video details two novel endoscopic techniques for resecting gastric exophytic subepithelial lesions, specifically gastrointestinal stromal tumors (GISTs), which originate from the muscularis propria. The techniques utilize natural orifice transluminal endoscopic surgery (NOTES) to access the peritoneum without external incisions. The first method, bidirectional full thickness resection (FCR), involves simultaneous luminal and peritoneal resection. The second method, serosal endoscopic dissection, preserves the mucosa by dissecting from the serosal side, avoiding endoscopic closure. Both techniques ensure complete resection and minimal exposure, marking advancements in treating subepithelial gastric tumors.
