About this trial
For patients with non-curative resection after endoscopic submucosal dissection (ESD) for early gastric cancer (EGC), complementary surgery is generally recommended. However, about 2/3 of patients have no remaining tumor in the stomach or regional lymph nodes. In this trial, Indocyanine Green (ICG)-guided lymphadenectomy with or without laparoscopic and endoscopic cooperative surgery (LECS) will be tested as a less invasive alternative in such cases. For patients with a primary radically resected EGC, ICG-guided lymphadenectomy alone will be performed. For patients with deep-margin positive EGC, ICG-guided lymphadenectomy and LECS will be performed, in order to ensure both local tumor control in the stomach and in regional nodes.
