Endoscopic submucosal dissection (ESD) has emerged as a pivotal therapeutic modality for early gastrointestinal (GI) cancers, providing a minimally invasive approach with curative potential. This technique enables the en bloc resection of neoplastic lesions confined to the mucosa and submucosa, thereby preserving organ function and reducing the need for more radical surgical interventions. ESD provides diagnostic clarity and enhances patient survival rates when performed by skilled practitioners in the early stages of GI cancers such as esophageal, gastric, and colorectal carcinomas. This article examines the indications, procedural advancements, technical considerations, and outcomes associated with ESD in early GI cancers. The challenges and complications that can arise are also highlighted. Additionally, we discuss the evolving role of novel techniques and adjunctive therapies to improve safety and efficacy. As the field progresses, ESD remains a cornerstone in managing early GI cancers, offering patients a promising option for organ preservation and long-term survival.
