ADVANCED ENDOSCOPIC PROC
Endoscopic mucosal resection (EMR) is an outpatient procedure used for resection of gastrointestinal mucosa for staging and treatment of neoplasms. This technique originates from Japan, where it was used for the diagnosis and treatment of EGC (early gastric cancer). Nowadays, this technique is used around the globe for various indications, including sessile colonic neoplasms and dysplastic Barrett mucosa.
Why Is EMR Performed?
It is a less invasive technique that is alternative to invasive and complicated surgeries for removing abnormal tissues. Your physician may recommend EMR to remove certain precancerous growths or early-stage cancers. Following are some of the benign and cancerous conditions that Endoscopic mucosal resection has been used to treat;
- Colon polyps
- Barrett’s oesophagus
- Oesophageal cancer
- Colorectal cancer
- Cancer of the small intestine (duodenum)
- Stomach (gastric) cancer
How to prepare

- Whether or not you have any previous medical (especially blood-clotting disorders, lung disease, heart disease, or diabetes) or surgical history
