METHODS： Thirty-one patients with hypopharyngeal squamous cell carcinoma had been operated, with radical intent, at our Institution in the period between 1978 and 2004. Due to obstructive tumor mass, in 7 （22.6%） patients, preoperative endoscopic evaluation of the esophagus and stomach could not be performed. In those patients, intraoperative endoscopy, made through an incision in the cervical esophagus, was standard diagnostic method for examination of the esophagus and stomach. RESULTS： We found synchronous foregut carcinomas in 3 patients （9.7%）. In two patients, synchronous carcinomas had been detected during preoperative endoscopic evaluation, and in one （with obstructive carcinoma） using intraoperative endoscopy. In this case, preoperative barium swallow and CT scan did not reveal the existence of second primary tumor within esophagus, despite the fact that small, but T2 carcinoma, was present. CONCLUSION： It is reasonable to use intraoperative endoscopy as a selective screening test in patients with obstructive hypopharyngeal carcinoma.展开更多
