Ectopic (heterotopic) gastric mucosa (EGM) of the upper esophagus, referred as inlet patch, is an asymptomatic benign lesion that is often detected during endoscopic examination. Although it is considered a source of adenocarcinoma in the upper esophagus, only 17 cases of adenocarcinoma have been reported previously. We report a rare case of adenocarcinoma(More)
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)
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)
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)
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)
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)
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)
