Congenital bronchoesophageal fistula (BEF) is rarely reported in adults in the English literature. Herein, we present a rare case of congenital BEF in a 43-year-old man that was incidentally found on esophagogastroduodenoscopy. Chest CT and barium esophagography revealed a fistula between his lower esophagus and the right lower lobe segmental bronchus. After the fistula was surgically treated, the fistula was no longer noted on follow-up barium esophagography.

Recently we successfully treated two cases of congenital bronchoesophageal fistula(BEF), communicating esophagus and right lower lobe, in adults by fistulectomy and right lower lobectomy. The fistulas were initially diagnosed on chest CT examination and confirmed by endoscopy and esophagography. The diagnosis of BEF is usually made by barium esophagography, esophagoscopy, and bronchoscopy. Although congenital BEF presented in adult life is a rare disorder, careful examination of chest CT films would disclose more cases of it , we think , than expected.

A 55-year-old-female was admitted for the evaluation of mass shadow on chest film. She complained of fever, chilling, cough, and whitish sputum. She did not give any history of choking or coughing when she ate. The chest CT showed lung aoocess in right lower lobe with extension of infiltration and air shadow in mediastinum. The esophagoscopy and esophagography were performed to find the cause of mediastinal infiltration, and bronchoesophageal fistula was detected in esophagography. The patient complained of severe chilling and febrile sensation after esophagography, mediastinitis aggravated by thin barium was suggested clinically. So, surgical drainage of lung abscess and thin barium was done urgently. One month after operation, follow-up of esophagoscopy and esophagography were done, the bronchoesophageal fistula was not detected.

Esophageal perforation due to blunt trauma is rare. A 67-year-old male presented to Konyang University Hospital with painful neck swelling. His neck was injured by blunt trauma at work. Esophageal perforation was detected by neck CT and esophagography. We performed primary repair of cervical esophagus through the Lt. neck approach. The postoperative course was uneventful and the patient was discharged at postoperative day 15.

We experienced a case of esophageal leiomyoma combined with achalasia that is very rare. Patient had suffered from severe dysphagia and postprandial vomiting and diagnosis was accomplished by esophagography, esophagoscopy, chest CT, and esophageal motility test. The operative treatment was done through left lateral thoracotomy by enucleation of the submucosal tumor and esophagomyotomy. By histopathological findings, the diagnosis of leiomyoma was confirmed and LES biopsy revealed absence of the ganglion cells of myenteric and Auerbach`s plexus. Symptoms of the patient were completely relieved and postoperative course was uneventful.

Aberrant right subclavian arteries were experienced in two young children. This is a rare aortic arch anomaly that usually does not produce symptoms. Symtomatic patients require surgical interventions.We describe two young children who had aberrant right subclavian artery with symptoms of difficulty in swallowing and respiratory problems. Diagnosis was made by esophagography, aortography and 3-Dimension chest CT. Operation had been advocated through right thoracotomy without difficulty for ligation, division and anastomosis to the ascending aorta. Dysphagia lusoria was immediately relieved and postoperative course was uneventful. We consider that the right thoracotomy is the choice of operative approach and noninvasive diagnosis by 3-Dimension chest CT is easily made for infant with aberrant right subclavian artery.

Background: The purpose of this study was to prospectively evaluate the predictive value of perfusion computed tomography (CT) for response of local advanced esophageal carcinoma to radiotherapy and chemotherapy. Materials and Methods: Before any treatment, forty-three local advanced esophageal squamous cell carcinomas were prospectively evaluated by perfusion scan with 16-row CT from June 2009 to January 2012. Perfusion parameters, including perfusion (BF), peak enhanced density (PED), blood volume (BV), and time to peak (TTP) were measured using Philips perfusion software. Seventeen cases received definitive radiotherapy and 26 received concurrent chemo-radiotherapy. The response was evaluated by CT scan and esophagography. Differences in perfusion parameters between responders and non-responders were analyzed, and ROCs were used to assess predictive value of the baseline parameters for treatment response. Results: There were 25 responders (R) and 18 non-responders (NR). Responders showed significantly higher BF (R:34.1 ml/100g/min vs NR: 25.0 ml/100g/min, p=0.001), BV (23.2 ml/100g vs 18.3 ml/100g, p=0.009) and PED (32.5 HU vs 28.32HU, P=0.003) than non-responders. But the baseline TTP (R: 38.2s vs NR: 44.10s, p=0.172) had no difference in the two groups. For baseline BF, a threshold of 36.1 ml/100g/min achieved a sensitivity of 56%, and a specificity of 94.4% for detection of clinical responders from non-responders. Conclusions: The results suggest that the perfusion CT can provide some helpful information for identifying tumors that may respond to radio-chemotherapy.

Background： Unilateral vocal cord paralysis(UVCP) by recurrent laryngeal nerve injury is one of the common laryngological diseases. Objectives : We attempted to study the clinical feature and the causes of UVCP and also tried to investigate what is to be the initial approach for determining the causes of unknown-origin UVCP Materials and methods The charts of 82 patients with the diagnosis of UVCP were reviewed. The records were analyzed for patient's gender and age, the status of paralysed vocal cord, the crucial tests for the diagnosis, and the etiologies. Results : forty-nine(59.8%) male and 33(40.2%) female patients were included in this study. The age group of sixth decade was most commonly involved. Most of the cases showed paramedian position of palsy, and the left side(59.8%) was more frequently attacked. The most common cause of UVCP in this series was the unknown origin, followed by the surgical trauma and neoplasms. The etiologies of the six(12.5%) unknown-cause cases were found with the further evaluation, with the most useful test being a CT scan. Conclusion： Chest X-ray, esophagography, and CT scan should be included in the mandatory initial investigation of patients with unknown-origin UVCP

A 3-month-old intact male Lakeland terrier was presented with recurring regurgitation after removing cervical esophageal foreign body by endoscopy. Blood and urine analysis, radiography, ultrasonography, fluoroscopic esophagography, computed tomographic angiography (CTA) were performed. In radiography and fluoroscopic esophagography, vascular ring anomaly was considered as the primary cause of megaesophagus, and CTA with gas-inflation of the esophagus was performed. Compressed esophagus, persistent right aortic arch (PRAA), aberrant left subclavian artery (LSA), and a venous structure which was confirmed in surgery to be incomplete type persistent left cranial vena cava (PLCVC) connected with the left side azygos vein were observed. Left deviation of the trachea was also revealed in CT, which implies the compression by left ligamentum arteriosum. Therefore, type 3 PRAA with left ligamentum arteriosum and aberrant LSA, was considered as a prior differential diagnosis. Surgical repair was performed and the clinical signs improved. This report describes CTA characteristics of combination of PRAA with aberrant LSA, incomplete PLCVC and Lt. azygos vein in a dog. Although not every vascular anomaly does induce clinical sign, some types can complicate the surgical procedure, and cause clinical signs. Therefore, thorough evaluation of vascular anomalies in the thorax is important, and CTA is a useful method in identifying multiple vascular anomalies in dogs.

Esophageal hemangioma is an extremely rare benign tumor that causes dysphagia and massive upper gastrointestinal bleeding. Although certain abnormalities seen on a barium swallow esophagography or at endoscopy may suggest an esophageal hemangioma, a contrast CT and radionuclide angiography using a blood-pool radiopharmaceutical can characterize the intense vascularity of the tumor. We experienced the ase of a 7$\times$7$\times$3.5 cm in size giant cavernous hemangioma of the lower 1/3 of esophagus in a 40 year old man. A mural cavernous hemangioma was diagnosed with a barium swallowed esophagogaphy, endoscopy, and a contrast CT. It was treated successfully by transthoracic esophagectomy including the tumor and esophagogastrostomy.
