1/4. Complication of esophageal self-dilation for radiation-induced hypopharyngeal stenosis.We present an unusual case of hypopharyngeal stenosis, secondary to radiation therapy for laryngeal squamous cell carcinoma, complicated by repeated inadvertent passage of a Maloney dilator through the larynx into the right mainstem bronchus during self-dilation. A brief review of esophageal/hypopharyngeal stenosis and management alternatives is presented. Self-dilation is presented as a therapeutic method for recurrent stenosis of the hypopharynx and esophagus. Recognition and avoidance of this complication is discussed.- - - - - - - - - - ranking = 1keywords = radiation-induced (Clic here for more details about this article) |
2/4. Treatment of a radiation-induced esophageal web with retrograde esophagoscopy and puncture.OBJECTIVE: To present a technique for the treatment of complete esophageal stenosis in the post-radiation patient that may be applied to selected patients with obstructing stenoses. STUDY DESIGN: A case report of the treatment of a post-radiation esophageal web. methods: A review of the patient's history of treatment and a discussion of reported treatment options. RESULTS: A complete obstruction of the cervical esophagus was diagnosed in a patient after chemoradiation for a hypopharyngeal carcinoma. Retrograde esophagoscopy through the patient's percutaneous endoscopic gastrostomy tube site aided visualization and perforation of the obstructing tissue. Subsequent dilation has allowed the patient to resume oral intake of a regular diet without restrictions. CONCLUSION: Combined direct laryngoscopy with retrograde esophagoscopy represents a viable alternative to more extensive approaches for recannulization of selected obstructing esophageal stenoses.- - - - - - - - - - ranking = 1keywords = radiation-induced (Clic here for more details about this article) |
3/4. radiation-induced oesophageal stricture in a case of Bloom's syndrome.A case of Bloom's syndrome with lung cancer treated by radiation therapy is described. Squamous cell carcinoma of the lung responded well to a tumour dose of 50.4 Gy. The most serious complication of therapy was an oesophageal stricture induced by only 30.6 Gy to the mediastinum. Brief reviews of radiation-induced oesophageal stricture and radiosensitivity in Bloom's syndrome are presented.- - - - - - - - - - ranking = 0.25keywords = radiation-induced (Clic here for more details about this article) |
4/4. Severe esophageal toxicity after thoracic radiation therapy for lung cancer associated with the human immunodeficiency virus: a case report and review of the literature.This case report documents severe esophagitis and rapid esophageal stricture formation in a man infected with the human immunodeficiency virus (hiv) who was treated with standard thoracic irradiation for locally advanced non-small-cell lung cancer. Severe late esophageal toxicity is a rare complication of radiation therapy in patients who are hiv negative, but those who are hiv positive may be at increased risk. This article reviews the literature suggesting that hiv infection may lead to unusually severe radiation-induced mucosal injury. High-dose chest irradiation should be performed with caution in this group of patients.- - - - - - - - - - ranking = 0.25keywords = radiation-induced (Clic here for more details about this article) |
