Application of ligating loops to control bleeding during endoscopic surgery for a highly vascular hypopharyngeal tumour.

Endoscopic treatment of hypervascular lesions of the hypopharynx is challenging because of difficulty in controlling bleeding during surgery. We report a highly vascular hypopharyngeal solitary fibrous tumour treated by endoscopic laser surgery combined with ligating loops. Application of dual ligating loops provided easy and secure haemostasis of the feeding artery before resection. Since the endoscopic approach is less invasive than the external approach, we confirm that it is worthwhile to attempt an endoscopic approach using ligating loops before resorting to the external approach in the treatment of hypervascular hypopharyngeal lesions.
