Endoscopic laser therapy for carcinoma involving the esophagus: the value of pretreatment computed tomography

Computed tomographic (CT) scans of the esophagus were performed on 15 patients with carcinoma of the esophagus or gastroesophageal junction prior to endoscopic laser therapy (ELT). The scans were evaluated for proximity to adjacent structures, symmetry, and luminal deviation, to help the endoscopist plan the route for therapy. A total of 50 procedures were performed without any serious complications. Pretreatment CT scans are a useful adjunct to ELT for carcinomas of the esophagus.
