Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
In this trial, Indocyanine Green (ICG)-guided lymphadenectomy including sentinel node resection, with or without complementary laparoscopic and endoscopic cooperative surgery (LECS) will be tested as a less invasive treatment option. For patients with radically resected EGC, ICG-guided lymphadenectomy alone will be performed. In patients with deep margin positive EGC, ICG-guided lymphadenectomy and LECS will be performed.
ICG-guided lymphadenectomy is performed by first injecting 100 times diluted ICG in four quadrants in the submucosa around the tumor scar with gastroscopy. After 15 minutes, the draining nodes will be visualized with laparoscopy, and locally resected. LECS is performed by endoscopic marking of the scar followed circumferential mucosal cutting, trimming, and perforation of the stomach followed by full-thickness resection of the scar with laparoscopy. After resection, the resected specimen will be taken out and the stomach defect sutured laparoscopically.
After the procedure, the patient will be presented at a multidisciplinary tumor board. If only clinical follow-up is recommended, the patient will be followed closely with gastroscopy and computer tomography (CT) scan every 3 months for the first year.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
ICG-guided lymphadenectomy +/- LECS
Laparoscopic and endoscopic cooperative surgery to locally resect the gastric scar. This method will we be used for cases where pathology showed positive vertical margin after ESD. Otherwise, submucosal injection of ICG in quadrants around the scar after ESD, followed by laparoscopic resection of positive lymph nodes after 15 minutes
ICG-guided lymphadenectomy
Submucosal injection of ICG in quadrants around the scar after ESD, followed by laparoscopic resection of positive lymph nodes after 15 minutes
Laparoscopic and endoscopic cooperative surgery (LECS)
Endoscopic marking and submucosal cutting around the scar after ESD, followed by perforation of the gastric wall and laparoscopic full thickness resection of the area under endoscopic guidance.
