Endoscopic Submucosal Dissection

Removing early cancers of the esophagus, stomach and colon
UH Digestive Health Institute- January 2016
The goal of ESD is to remove lesions or neoplastic growths in one piece (also known as en bloc). These are growths that have clear lateral and deep margins. This can be achieved when the neoplasm is of favorable histology (well or moderately differentiated) and involves only the most superficial layers of the gastrointestinal tract. Deeper invasion or poorly differentiated neoplasms require more traditional surgical approaches, or a combination of radiation and chemotherapy.
This case (Figures 1-5) illustrates endoscopic resection of an early squamous cell esophageal cancer from the mid-esophagus. The patient presented with non-cardiac chest pain, which was thought to be unrelated to this early stage neoplasm. The ESD procedure removed the lesion with clear lateral and deep margins. The resection specimen measured 2.5 x 1.9 x 0.4 cm.
After the procedure, the patient was hospitalized for observation due to symptoms of chest pain and exposure of the muscle layer fibers. A CT scan of the chest revealed a small leakage of carbon dioxide, which had been used for insufflation during the procedure. The patient had an otherwise uneventful recovery.
