Background and Objectives : Narrow Band Imaging(NBI) is a novel optical technique that enhances the visualization of superficial microvascular architecture which is commonly increased and founded as an irregular shape in a neoplastic lesion. The aim of this study is the evaluation of the usefulness of NBI in the diagnosis of Head and Neck Cancer. Subjects and Methods : From December 2009 to January 2011, 31 consecutive patients who were diagnosed with head and neck malignancy were enrolled in this prospective study. The malignant findings of NBI were demarcated brownish lesion or increased intraepithelial papillary capillary loops(IPCLs) with or without irregularity. Results : There were 29 cases(93.5%) of well demarcated brownish lesion, 26 cases(83.9%) of increased IPCLs and 4 cases(12.9%) of satellite lesions. Diagnostic accuracy of endoscopic examination was increased from 83.9% to 93.5%, when NBI was applied to the conventional endoscopy(p>0.05). Conclusion : NBI is a powerful and safe screening test, which can be performed in out patient clinic without any supplementary procedure.

성별, 직업, 성품, 생활양식이 전혀 다른 K43과 C45 환자의 위 내시경적 소견과 치료방법을 논의하였다. K43은 잘못된 식습관과 스트레스에 의한 미란성 위염환자로서 제산제와 함께 H2-수용체 길항제, H+/K+-pump 억제제, prostaglandin 제제, colloidal bismuth, sucralfate prokinetics 등 전통적인 약물에서부터 부작용을 감소시킨 최근에 개발된 약물에 이르기까지 효과가 인정된 약물들을 폭넓게 사용하였으나 증상을 개선치 못하였으며, 임상병리 검사와 상복부 초음파 검사는 정상이었으나, 소화생리기능 검사에서 visceral hypersensitivity를 나타내었다. 그러나 C45는 평소에 두통으로 NSAIDs를 습관적으로 복용한 경험에 의하여 발생되었을 것으로 추정되는 전형적인 위·십이지장 궤양의 환자로서 H. pylori 박멸제와 함께 일반적인 소화성 궤양의 치료제로 활동기에서 치유기로 증상을 크게 완화시켰다. 특히 K43은 amitryptyline을 투여하였으나 난치성 환자로 남아 있다. 이러한 원인불명의 비궤양 환자는 미국에서 해마다 15%씩 증가하는 추세에 있고 적절한 치료법도 없으며, 우리 나라에서는 통계치도 없는 실정인 점을 지적하고 싶다.

Benign pulmonary tumors are rare entities, and among them bronchial lipomas are the most uncommon. Up to date, about 80 cases have been reported in the English literature. But, the bronchial lipoma with extrabronchial growth causing middle lobe syndrome and pneumonia is extremely rare. Bronchial lipomas, mainly arising from normal fatty tissue of the proximal portion of the lobar or segmental bronchi, are histologically benign. But if diagnosis and treatments are delayed, they can produce extensive pulmonary parenchymal damage and irreversible brochiectasis distally. So whenever possible, the treatment of choice is resection by means of bronchoscopy via early diagnosis. But if endoscopic removal is not possible because the distal end of the tumor could not be visualized by fiberoptic bronchoscopy or if the nature of the tumor is unclear, surgery is necessary, with lobectomy or pneumonectomy being required in most cases due to the extensively damaged pulmonary parenchyma. We present a case of bronchial lipoma with extrabronchial growth, with a review of the literature and report of an unusual case.

The pathomechanism of obstructive sleep apnea(OSA) is not clearly elucidated. The possible mechanisms are pathologic reduction of pharyngeal muscular tonus during sleep, abnormal anatomical stenosis of nasopharyx or a combination of the above two mechanisms. It is very important to find the cause(anatomical location or pathologic dynamic change) of OSA in order to treat it. Cephalometric analysis in patients with obstructive sleep apnea is a good method for evaluating anatomical morphologic change but it cannot give any information about the dynamic changes occurring during sleep. On the contrary, nasopharyngeal endoscopy offer 3 dimensional image and information about the dynamic changes. Accordingly, these two diagnostic tools can be utilize in the diagnosis and treatment planning of OSA Cephalometric analysis of craniofacial skeletal and soft tissue morphology in 53 patients with OSA and 43 controls was performed and cephalometric analysis and nasopharygeal endoscopy were performed in 9 patients with OSA in order to come up with individualized therapy plans. Following results were obtained ; Patients with OSA showed 1. body weight gain 2. clockwise mandibular rotation 3. increased anterior lower facial height 4. inferiorly positioned hyoid bone 5. increased length of soft palate 6. decreased sagittal dimension of nasopharyx 7. increased vertical length of inferior collapsable nasopharyx 8. increased length of tongue Through cephalometric analysis and nasopharygeal endoscopy(mutually cooperative in diagnosis), 9. one can find the possible origin of OSA and make a adequate individualized therapy plan and predict accurate prognosis. Cephalometric analysis and nasopharygeal endoscopy are highly recommended as a diagnostic aid in OSA patients

Purpose: Recently, the prevalence of eosinophilic gastrointestinal disease (EGID) has shown an increasing trend worldwide. As the diagnosis of EGID requires invasive endoscopy with biopsy, noninvasive markers for detecting EGID in suspected patients, particularly children, are urgently needed. Therefore, this study aimed to evaluate the diagnostic accuracy of serum eosinophil cationic protein (ECP) beyond peripheral eosinophil counts in pediatric patients with EGID. Methods: Overall, 156 children diagnosed with EGID were enrolled and 150 children with functional abdominal pain disorder (FAPD) were recruited as controls. All participants underwent endoscopic biopsy in each segment of the gastrointestinal (GI) tract and serum ECP measurement, as well as peripheral eosinophil percent and absolute eosinophil count. Results: Comparing EGID (n=156) with FAPD (n=150) patients, serum ECP levels were significantly higher in pediatric patients with EGID than in those with FAPD (25.8±28.6 ㎍/L vs. 19.5±21.0 ㎍/L, p=0.007), while there was no significant difference in peripheral eosinophil percent and absolute eosinophil counts between the two groups. Serum ECP levels were correlated with peripheral eosinophil percent (r=0.593, p<0.001) and the absolute eosinophil count (r=0.660, p<0.001). The optimal cutoff value of serum ECP for pediatric EGID was 10.5 ㎍/mL, with a sensitivity of 69.9% and a specificity of 43.4% with an area under the receiver operating characteristic curve of 0.562. Conclusion: The combination of serum ECP levels and peripheral eosinophil counts, when employed with appropriated thresholds, could serve as a valuable noninvasive biomarker to distinguish between EGID and FAPD in pediatric patients manifesting GI symptoms.

Carcinosarcoma is a rare malignant, biphasic tumor comprised of carcinoma and sarcoma components. In the gastrointestinal tract, carcinosarcoma is most frequently seen in the esophagus and rarely in the stomach. We report a 51-year-old female patient with 2-month-history of epigastric pain and dyspepsia. Endoscopic finding revealed a huge ulcerative lesion that infiltrated from the antrum to the mid-body. An endoscopically taken biopsy revealed poorly differentiated malignant round cell neoplasm. After the palliative subtotal gastrectomy, immunohistochemical studies showed two positive reactions for the epithelial marker and mesenchymal marker. Based on the above findings, the patient was diagnosed with gastric carcinosarcoma. The immunohistochemical analysis is a critical method in making an accurate diagnosis of carcinosarcoma.

Gardner syndrome is known as a variant of familial adenomatous polyposis. This syndrome is characterized by multiple intestinal polyposes, osteomas, and epidermoid cysts. In addition, dental abnormalities include an increased frequency of multiple odontomas, as well as supernumerary and impacted teeth. The authors report the case of a 7-year-old male patient with Gardner syndrome. Radiographic findings revealed multiple osteomas in both sides of the maxilla, multiple diffuse enostoses in both jaws, and a complex odontoma in the left mandibular body. Two years later, multiple epidermoid cysts on the scalp were found. Since this patient was suspected to have Gardner syndrome, the authors recommended gastrointestinal endoscopy to check for intestinal polyposis. Gastrointestinal endoscopic examination revealed multiple polyposes in the upper gastrointestinal tract and fundus of the stomach. As a result, the final diagnosis was Gardner syndrome.

Bilateral vocal fold immobility (BVFI) is a challenging condition which may result from diverse etiologies including vocal fold paralysis, synkinesis, cricoarytenoid joint fixation, and interarytenoid scar. Most patients present with dyspnea and stridor, but sometimes with a breathy dysphonia. Careful history taking, laryngoscopic evaluation under general anesthesia or awaken status, laryngeal EMG, and imaging studies with CT and/or MRI are helpful for providing a precise diagnosis and planning appropriate managements. In children, congenital neurological disorder is one of the most common etiologies, and spontaneous recovery has been reported in more than 50% of cases. Therefore, observation for more than 6 months while securing the upper airway with tracheostomy if needed is a generally accepted rule before deciding any destructive procedure to be undertaken. In children with advanced posterior glottic stenosis, laryngotracheal reconstruction with rib cartilage graft should be considered. In contrast to children, BVFI most commonly occurs as sequalae of surgical complication in adults. Diverse static or dynamic procedures can be applied; posterior cordotomy, vocal fold lateralization, endoscopic or open arytenoidectomy, arytenoid abduction, and reinnervation, electrical laryngeal pacing, which need to be carefully selected according to each patient's needs and pathophysiology of BVFI.

A 54 year old man was referred to our hospital with gastric cancer. The patient had a history of splenectomy and a left nephrectomy as a result of a traffic accident 15 years earlier. The endoscopic findings were advanced gastric cancer at the lower body of the stomach. Abdominal ultrasonography (USG) and magnetic resonance imaging demonstrated a metastatic nodule in the S2 segment of the liver. Eventually, the clinical stage was determined to be cT2cN1cM1 and a radical distal gastrectomy, lateral segmentectomy of the liver were performed. The histopathology findings confirmed the diagnosis of intrahepatic splenosis, omental splenosis. Hepatic splenosis is not rare in patients with a history of splenic trauma or splenectomy. Nevertheless, this is the first report describing a patient with gastric cancer and intrahepatic splenosis that was misinterpreted as a liver metastatic nodule. Intra-operative USG guided fine needle aspiration should be considered to avoid unnecessary liver resections in patients with a suspicious hepatic metastasis.
