Endoscopic Submucosal Dissection (ESD): Advanced Minimally Invasive Tumor Removal Endoscopic Submucosal Dissection (ESD) is an advanced endoscopic procedure used to remove abnormal or cancerous growths from the lining of the digestive tract. It allows for precise removal of larger or deeper lesions in areas such as the esophagus, stomach, and colon. The procedure is performed using specialized instruments inserted through the mouth, avoiding the need for open surgery. One of its key advantages is the ability to remove the entire lesion in a single piece, which supports accurate diagnosis and reduces the risk of recurrence. ESD is often considered for early-stage conditions where preserving surrounding healthy tissue is important. Careful evaluation is required to determine suitability for this technique. Recovery time may vary, but it is generally shorter compared to traditional surgical methods. Patients are monitored after the procedure to ensure proper healing. Follow-up assessments help track recovery and long-term outcomes. With proper care, ESD can support effective treatment while maintaining digestive function.
