OBJECTIVES To evaluate the diagnostic value of rhinolaryngoscopy using a narrow band imaging (NBI) system in detecting squamous cell carcinoma of the head and neck (SCCHN) in patients with esophageal cancer (EC). STUDY DESIGN Prospective study. SUBJECTS AND METHODS Between January 2006 and December 2006, 667 consecutive EC patients underwent(More)
The clinical profile of thromboangiitis obliterans (TAO) has been changing. The purpose of this study was to clarify the distribution of arterial involvement in this disease, based on a nationwide survey carried out in 1993. A total of 825 TAO patients with complete records were analyzed. There were 749 men and 76 women, with a mean age of 50.8 ± 0.4 years.(More)
PURPOSE We report early outcome of our modified papillary muscles approximation (PMA) as an adjunct to mitral annuloplasty (MAP) by analyzing the mitral coaptation zone echocardiographically and clinical outcome in three different procedures. METHODS Mitral valve coaptation depth (MVCD) and tenting area were measured in patients with ischemic (n=8) or(More)
Percutaneous cardiopulmonary bypass support (PCPS) has become a widespread standard modality for the treatment of circulatory collapse; however, its clinical use for postcardiotomy low cardiac output syndrome (LOS) has been reported to be unsatisfactory. We reviewed the clinical outcomes of twenty-three patients undergoing cardiac surgery and treated with(More)
Mitral valvuloplasty using Gore-Tex (W.L. Gore & Associates, Inc, Flagstaff, AZ) as artificial chordae is often associated with difficulties in determining the length of the artificial chordae, as well as preventing knot slippage, especially for patients with broad anterior leaflet prolapse. We describe a simple technique that enables surgeons to easily(More)
BACKGROUND The nonrecurrent inferior laryngeal nerve (NRILN) is always associated with the aberrant subclavian artery. CT images can detect this vascular anomaly, which predicts an NRILN. The purpose of this study was to report our procedure to identify the NRILN in patients with the aberrant subclavian artery. METHODS Four of 730 patients undergoing(More)
We evaluate the value of laryngoscopy using narrow band imaging (NBI) system in the diagnosis of precancerous and cancerous laryngeal lesions. Thirty-four patients were suspected of having a total of 35 precancerous or cancerous laryngeal lesions among patients receiving conventional white-light laryngoscopy. All 34 patients underwent laryngoscopy with NBI(More)
OBJECTIVES Narrowband imaging (NBI) is a novel optical technique that enhances the diagnostic capability of endoscopes in characterizing tissues by using narrow-bandwidth filters in a video endoscope system. The purposes of this study were to verify the effectiveness of the NBI system in conducting endoscopic screening at the oropharynx and the hypopharynx.(More)
