Complication-Free Laryngeal Surgery after Irradiation Failure with Prostaglandin E1 Administration

Abstract

To examine the usefulness and efficacy of administration of prostaglandin E1 (PGE1) after laryngeal surgery in patients who were previously treated with radiotherapy, we retrospectively examined the clinical data of 12 patients who had undergone partial laryngectomy and 21 patients who had undergone total laryngectomy. Complications were observed in 5 of the 7 cases treated with partial laryngectomy without PGE1 administration, while no complications were observed in the 5 cases treated with PGE1 after operation. Also, complications, including major leakage, were observed in 6 of the 15 patients who underwent total laryngectomy without PGE1, and no complications were observed in the 6 patients who received PGE1. The hospital stay was shorter for the patients treated with PGE1 than for those not receiving such treatment. Although this study was a small, nonrandomized pilot trial, the results indicated that PGE1 administration may be useful and effective for patients who undergo laryngeal surgery after irradiation failure, in decreasing the risk of postoperative complications and increasing the quality of life of the patients.
