The gastrointestinal endoscopic mucosal resection treatmentis a process for removal of cancerous or other abnormal tissues present in the digestive tract. TheEMR procedureis executed with the help of a long and slender tube with a video camera, light, and other needful instruments. During the EMR of the upper digestive tract, the endoscope or the tube is passed down the throat for detecting and reaching out an abnormality in the esophagus, stomach, and duodenum. This tube is inserted and guided upwards from the anus.Gastroenterologistsgenerally recommend thisEMR surgeryfor collecting tissues that can be diagnosed. If there is the presence of cancerous cells, the endoscopic mucosal resection treatment can help in determining whether cancer has reached the tissues underlying the stomach lining. This process is a less invasive alternative to a comprehensive surgery that can help in removal of lesions from the digestive tract lining. Then the tissues are thoroughly diagnosed to determine whether they are early stage cancer or precancerous lesions that may become cancerous in near future. Gastroenterologists, who have ample knowledge and education on this technique, normally perform the endoscopic mucosal resection. The procedure is quite short. There are also some risks involved with the process, which may include bleeding though it can be corrected during the process. Puncture or perforation of the digestive tract wall and narrowing of the esophagus due to removal of lesion encircling the esophagus, may cause difficulty in swallowing. However, the result is a body, free from life threatening cancer.
