Endoscopic Submucosal Dissection

Endoscopic submucosal dissection (ESD) is a minimally invasive procedure used to remove large or deeply embedded gastrointestinal tumors. It is a type of endoscopy where a thin, flexible tube is inserted into the gastrointestinal tract and the tumor is excised using a high-frequency electric current. The procedure is usually done under general anesthesia. In ESD, the endoscope is inserted through the mouth into the stomach and duodenum. Once the tumor is located, a thin knife is used to dissect the tumor from the underlying tissue. The knife is then used to cut a narrow channel around the tumor, and the tumor is then removed by cutting it away from the surrounding tissue. The cut is sealed with an endoscopic clip or suture. The advantages of ESD include less pain, fewer complications, and a shorter recovery time compared to traditional surgery. It is also less costly due to less time spent in the operating room and fewer complications. The risks associated with ESD include bleeding, infection, and perforation of the gastrointestinal tract. In addition, some tumors may not be completely removed, and there is a risk of recurrence. ESD is a safe and effective procedure for the removal of large or deeply embedded tumors in the gastrointestinal tract. It is less invasive than traditional surgery and has a shorter recovery time. However, it is important to discuss the risks with your doctor before undergoing the procedure.
