Endoscopic Submucosal Dissection (ESD) is a minimally invasive procedure used to remove certain types of gastrointestinal tumors. It allows doctors to excise lesions from the digestive tract with precision, reducing the need for more invasive surgeries. ESD has gained prominence for its ability to treat early-stage cancers and precancerous conditions effectively. As technology advances, ESD procedures are becoming safer, faster, and more accessible worldwide.

Preparation: The patient undergoes initial assessment, including imaging and endoscopy, to locate the lesion. The area is cleaned, and anesthesia is administered to ensure comfort during the procedure.
Injection: A solution, often saline mixed with a dye, is injected into the submucosal layer beneath the lesion. This lifts the tissue, creating a cushion that facilitates safe dissection and reduces the risk of perforation.
Incision: Using specialized endoscopic tools, the surgeon makes a precise incision around the lesion’s perimeter, marking the boundaries for removal.
Dissection: The submucosal layer is carefully dissected to free the lesion from the underlying tissue. This step requires skill to avoid damaging adjacent structures.
Retrieval and Closure: The excised tissue is retrieved for pathological examination. The site may be closed with clips or other devices to promote healing and prevent complications.
Each step emphasizes precision and safety, leveraging advanced endoscopic instruments and imaging technologies. Continuous innovations aim to streamline these steps, making ESD more efficient and accessible.

ESD is primarily used in gastroenterology to treat early-stage cancers of the stomach, esophagus, and colon. For example, early gastric cancer detected during routine screening can be removed via ESD, often leading to better outcomes and less invasive procedures compared to traditional surgery.
In addition, ESD is employed for removing precancerous lesions, such as dysplastic polyps, which could develop into malignancies if left untreated. Hospitals and specialized clinics benefit from ESD by offering minimally invasive options that reduce patient recovery time and hospital stays.
Beyond gastroenterology, ESD techniques are being adapted for other fields, including pulmonology and urology, where precise tissue removal is necessary. The outcomes generally include higher success rates, fewer complications, and improved patient satisfaction.
