Esophageal schwannoma is a very rare submucosal tumor. We report successful management of esophageal schwannoma in a 41-year-old man who complained of progressively worsening dysphagia. A huge submucosal tumor was found via endoscopy and a chest computed tomography scan. Esophagectomy was performed with no post-operative complications. Post-operative immunohistochemistry staining showed a positive result for S-100 and negative results for c-kit and CD34. The post-operative mild dysphagia persisted, and the follow-up endoscopic findings revealed anastomosis site stenosis. Approximately 2 months later, we performed endoscopic balloon dilatation. We report herein a case of esophageal schwannoma with reviews.

Ossification of the yellow ligament (OYL) is a pathologic condition that causes spinal stenosis, which is a form of ectopic ossification. OYL causes compressive myelopathy and radiculopathy. Although the pathogenesis of OYL is still unclear, diffuse mechanical stresses and degenerative changes caused by extreme ranges of motion may be related to the development of OYL in young sportsmen. Here we report an interesting case of thoracic radiculopathy due to OYL in a 35-year-old male amateur judo player who was successfully treated with continuous thoracic patient controlled epidural analgesia and epidural adhesiolysis.

Objective : With the increased use of interspinous spacers in the treatment of lumbar stenosis, knowledge of the geometry of the interspinous space is important. To prevent dislodgment of an interspinous spacer, the accurate depth and width of the interspinous space needs to be established to facilitate the best intraoperative selection of correct spacer size. Methods : To determine the depth and width of the interspinous space, two methods are available which utilize plain film and magnetic resonance imaging (MRI). Data analysis of the interspinous depth and width was undertaken in 100 patients. Results : The standard deviations were variable, since skin thickness (zone 1) was altered by sex and age. The difference in the zone 1 distance between adjacent interspinous processes varied according to gender (p<0.05), but was not influenced by age [p=0.32 by analysis of variance between groups (ANOVA)]. Zone 2, the supraspinous, and zone 3, the interspinous ligament depths, comprise the operative working area during insertion of an interspinous spacer. There were no differences with regard to gender or age (p>0.05). For zones 6 and 7, the interspinous distances at the narrowest and widest points, respectively, were found to decrease with the aging process, but the decrease was not statistically significant. There were no differences with regard to gender (p>0.05). Conclusion : This study provides additional information on the interspinous space. This statistical data are valuable for use in the design of interspinous spacers.

Kawasaki disease (KD) is an acute vasculitis of small and medium sized arteries. Even many years after onset, aneurysms and stenosis in coronary arteries may lead to an acute myocardial infarction, which is described as atypical or missed KD in childhood. KD is an underlying disease of young adults with acute myocardial infarction. We report on a rare case involving a total occlusion in the proximal left anterior descending coronary artery combined with a giant left main aneurysm in a young adult patient with acute myocardial infarction ascribed to antecedent KD that is undefined but almost certain.

Objective : The purpose of this study was to review the safety and durability of aneurysms treated with stent-assisted coiling of ruptured anterior communicating artery aneurysms with small parent vessels (< 2.0 mm). Methods : Retrospective review of all ruptured aneurysm treated with stent assisted endovascular coiling between March 2005 and March 2009 at our institution was conducted. We report 11 cases of the Neuroform stent placement into cerebral vessels measuring less than 2.0 mm in diameter (range, 1.3-1.9 mm) in anterior cerebral artery. Clinical follow-up ranged from 3 to 12 months and imaging follow-up was performed with cerebral angiography at 6 months and 12 months after discharge. Results : Complete occlusion was achieved in 10 patients, and a remnant neck was evident in one. No stent displacement or no dislodgement occurred during stent placement. There was no evidence of thromboembolic complication, arterial dissection and spasm during procedure. We performed follow-up angiography in all patients at 6 months and/or 12 months from the first procedure. The follow-up angiographic data showed successfully results except one in-stent stenosis case. All patients improved clinical performances except one patient with severe vasospasm who showed poor clinical condition initially. Conclusion : We have safely and successfully treated 11 vessels smaller than 2.0 mm in diameter with self-expanding stents with good short and intermediate term results. More clinical data with longer follow-ups are needed to establish the role of stent-assisted coiling in ruptured aneurysms with small parent vessels.

OBJECTIVE : To study the management (diagnostic and therapeutic) of esophageal foreign bodies with rigid esophagoscopy. MATERIAL AND METHODS : All 100 patients admitted to the Dankook University Hospital for ingestion of foreign bodies between May 1994 and July 1999. The outcome for each patient was determined by examining hospital records of demographic information, identification of the foreign body and the removal procedure used. RESULTS : Rigid esophagoscopy was performed for suspected foreign bodies in 100 cases an impacted. The most frequent location was the upper third of the esophagus (68%). The most common type of foreign body was fish bones in adult(61%) and coins in children(70%). In 12 patients. flexible endoscopy had failed previously to remove the foreign body and 4 cases were migrated esophageal metal stent in esophageal stenosis. CONCLUSIONS : The rigid esophagoscopy is appropriate techniques for managing esophageal foreign bodies.

Aspiration of foreign bodies into the tracheobronchial tree is unusual in adults and it may result in Proximal airway obstruction and acute life-threatening asphyxia. It can be diagnosed by history of aspiration or visualizing the foreign body by chest roentgenogram or bronchoscopy. But it is rarely considered in adults with subacute or chronic respiratory symptoms without a definite history which suggests an aspiration. A 70-year-old woman was admitted to the hospital due to productive cough for two months and dyspnea which aggravated since the day before admission. Chest X-ray showed Pneumonic infiltration on left upper lobe and right lower lobe. Despite several days of conventional therapy, the patient complained of severe dyspnea and wheezing. We performed chest CT to rule out endobronchial stenosis, and it revealed the narrowing of left main stem bronchus compatible with endobronchial tuberculosis. Fiberoptic bronchoscopy for confirmation disclosed a $3.2{\times}0.7{\times}0.2$cm sized foreign body located longitudinally at the left main stem bronchus. We removed it with alligator forcep and it proved In be a piece of artificial denture. The patient remembered losing it while severe coughing on the day before admission. The microscopic examination of bronchial washing fluid revealed numerous acid fast bacilli. After removal of the foreign body, the patient showed marked improvement in symptom and pulmonary function test. Here we report a case of Pulmonary aspiration of foreign body which is confused with endobronchial tuberculosis with a review of the literature.

Pure esophageal atresia without tracheoesophageal fistula is a uncommon form of congenital malformation of the esophagus, which is able to be suspected by fetal ultrasonograpy before delivery and diagnosed definitely by simple chest X-ray and esophagogram immidiately after delivery. We performed delayed primary repair in 2 cases of pure esophageal atresia by using stomach for conduit in one case and colon in the other case. But there were graft failure in the latter case, so reoperation was performed by using stomach. Postoperatively, two patients showed no stenosis and leakage in anastomotic site and were discharged in good oral intake without dysphagia.

Purpose : This study was carried out to evaluate correlation between Bone Mineral Density(BMD) and degenerative lumbar disease in postmenopausal low back pain patients. Methods : 69 postmenopausal patients with low back pain were examined. Magnetic resonance imaging was performed to evaluate degenerative lumbar disease and bone mineral density of lumbar spine was measured by Dual energy X-ray absorptiometry. Data were analyzed by Pearson's Linear Correlation Coefficient. Results : In postmenopausal patients with low back pain, BMD(T-score, Z-score) had negative correlation with the grade of intervertebral disc herniation and positive correlation with weight. Other lumbar diseases including Spinal stenosis, Spondylolisthesis and Facet joint arthrosis didn't have significant correlation with BMD. Conclusion : In postmenopausal patients with low back pain, BMD(T-score, Z-score) had inverse relationship with the grade of intervertebral disc herniation.

With the adevance of widespread mechanization and high-speed era, the incidence of traumatic rupture of the tracheobronchial tree has been increased considerably. We have experienced these diseased of the 3 cases in our department. The first case was a 25 year old male who was severe dyspneic and subcutaneous emphysema, hemoptysis, and hemopneumothorax of both side were noted. During tracheostomy, it was found that the 2net ring of the trachea was ruptured. No definitive procedure was made on admission. Corrective surgery was performed with end-to-end anastomosis on 31 post-traumatic day. The second case was a 43 year old female who received multiple stab wounds on the anterior neck and it was found that the cricoid cartilage was transected partially. The injured cartilage was approximated with interrupted suture of No. 600 wire. The third case was a 19 year old male who had sustained a compression chest injury without external wound or rib fracture. At five days after trauma, he had suffered from dyspnea, and obstruction of the left main bronchus due to traumatic bronchial rupture was confirmed by means of bronchoscopy and bronchography at two weeks after the trauma. End-to-end anastomosis of the bronchus was performed and the left lung was aerated well. Mild postoperative stenosis of trachea was remained in the first case. Others were uneventful.
