Outpatient management of esophageal cancer with endoscopic Nd:YAG laser.

In 50 inoperable patients with advanced malignant obstruction of the esophagus, endoscopic Nd:YAG laser treatment was used for palliation of dysphagia. In 30 of these patients, treatment was carried out entirely in an outpatient setting, providing more time at home and saving costs of hospitalization. Most patients had received prior radiation and chemotherapy. All were unable to swallow solid food; 16 had difficulty with liquids. Palliation was achieved in 69% allowing patients to eat a nearly normal diet. Therapy was least successful in cancers involving the cervical esophagus, in cancers more than 8 cm in length, and in cancers that were primarily infiltrating or extraluminal. Epidermoid carcinomas and adenocarcinomas were effectively treated, except for adenocarcinomas of the gastric cardia, which tended to be infiltrating. There were two serious but nonfatal complications, one perforation and one episode of bleeding, directly attributable to Nd:YAG laser therapy. An esophageal dilation prior to endoscopic Nd:YAG laser treatment facilitated outpatient management.
