Endoscopy Of The Upper Gastrointestinal Tract.
Photodynamic therapy can be a curative modality in advanced esophageal carcinoma.
Endoscopic ultrasound is the method of choice for determining the stage of gastric lymphoma and monitor the response to therapy. Patients that rebleed after the first attempt at endoscopic hemostasis should go to surgery. The most common submucosal masses in the upper GI tract are lipomas. Currently there are no reliable medical, endoscopic or surgical therapy to eliminate intestinal metaplasia of the esophagus. Endoscopic ultrasonography is more accurate than CT scanning in determining the stage of esophageal tumors.
