This round of tests in patients with UGI and Esophagography data collected by national and international reference levels based on the original set of guidelines and fluoroscopy, through the provision of medical radiation exposure reduction and further optimization of Defense to realize that is intended. 359 names in our hospital underwent Esophagography 302 patients who underwent UGI average fluoroscopy time and number of images to calculate the average 21 cm Acryl phantom dose for 10 seconds and 20 seconds, average area dose and the area dose of 1 spot image, 5 spot consecutive images by measuring the patient dose and third quartile of the mean area dose was set seonryangin reference dose. Esophagography average patient dose was set to 30.05 $Gy{\cdot}cm^2$, DRL was set at a 25.37 $Gy{\cdot}cm^2$. Average dose of UGI patients were selected as 45.33 $Gy{\cdot}cm^2$, DRL was set at a 34 $Gy{\cdot}cm^2$. UGI patients with established average dose recommended in the 2008 national recommendation from the UGI examination with a dose of less than 49.7 $Gy{\cdot}cm^2$ seonryangin is evaluated. This Note examines the dose of self-aware through education recognizes the importance of dose reduction and examine if their efforts and further reduce patient dose could achieve optimization of the medical exposure is considered.

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.

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.

Pharyngoesophageal diverticulum is a well-known disease entity but is seldomly reported in Korean literature. Recently the authors experienced two cases of pharyngoesophageal diverticulum. A 46 year old female and a 51 year old female patients were admitted due to foreign body sensation in esophagus and dysphagia. Preoperative esophagography and esophagoscopy confirmed the diagnosis of pharyngoesophageal diverticulum in each patient. The authors performed one-stage pharyngoesophageal diverticulectomy and myotomy. Postoperative esophagography revealed no diverticulum or stenosis and symptoms were markedly relieved.

The first description of the pathologic anatomy of esophageal atresia was presented by Duration in 1670, it was not successfully treated until 1939 when the first two survivors of staged correction were described by Ladd and Levin. In 1941 Haight and Towsley performed the first successful primary repair. Recently we were experienced a case of esophageal atresia with tracheoesophageal fistula an infant patient who presented the symptoms of vomiting and dyspnea. The diagnosis was made by the esophagography with Diagnosis. The operation was performed extrapleurally through 4th intercostal space after gastrostomy. The fistula was closed by triple ligation and the upper pouch was then brought into apposition with the presenting surface of the lower esophageal segment and an end to side anastomosis was fashioned with a single layer of sutures. Operative patient tolerated all the operative procedure well in spite of postoperative respiratory complication and recovered uneventfully, permitted feeding on 9th postoperative day after esophagography.

A 59-year old woman visited us for incidentally detected posterior mediastinal mass. Preoperative esophagography, esophagoscopy, esophageal ultrasound and computed tomography showed a esophageal submucosal tumor. With the diagonsis of esophageal leiomyoma, the patient underwent right side video-assisted thoracoscopic surgery (VATS): The mediastinal pleura and the esophageal muscle layers were longitudinally opened and the tumor was enucleated. Esophagography performed at 6th postoperative day revealed no esophageal mucosal bulging or leakage. The patient was discharged reveiving a soft diet on the 7th postoperative day.

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.

This study intends to investigate patients' exact exposure doses by comparatively measuring ESD (Entrance Surface Dose) with the DAP meter, which excludes scattered rays, and ESD with the Xi multifunction meter, which includes scattered rays, by posture changes for Esophagography test and UGI test. The materialwere examined through Sonialvision-SafireII SPEC overtube system. ESD was measured by using the DAP meter, and as a tool to measure ESD including scattered rays on the plane of incidence of human phantom, the Xi multifunction meter was used. The average fluoroscopic time of Esophagography test was 4.192 minutes and the average number of images was 47.7, while the average fluoroscopic time of UGI test was 6.881 minutes and the average number of images was 37.8. The ratios of the incident dose of DAP meter and the ESD of Xi meter were calculated bydividing the fluoroscopic time and the number of images by each posture change. As for Esophagography test, the dose increased by 21.6~55.5% in the fluoroscopic test and by 4.8~24.7% in the spot test. In the front spot test, however, the does increased by as little as 5.3%. As for UGI test, the dose increased by 21.1~49.5% in the fluoroscopic test and by 10.1~34.9% in the spot test. It is expected that measuring doses in consideration of scattered rays by posture changes will be an important index in evaluating and managing patients' exact exposure doses for each test above. Furthermore, it is judged that this sort of study is inevitable and desirable to reduce patients' exposure doses after all.

Esophageal atresia with double tracheoesophageal fistula is a very rare anomaly and is difficulty to diagnose preoperatively. We treated a full term baby with esophageal atresia with double tracheoesophageal fistula. At the first operation, only the distal tracheoesophageal fistula was identified and ligated. When the upper esophageal pouch was opened, intermittent air leakages in sequence with positive bagging were noticed. However, intraoperative bronchoscopy did not identify a fistula in the proximal pouch, and the operation was completed with end to end anastomosis of the esophagus. On the $7^{th}$ postoperative day, esophagography showed another tracheoesophageal fistula proximal to the esophageal anastomosis. A wire was placed in the fistula preoperatively under bronchoscopy. At the 2nd operation through the same thoracotomy incision the proximal fistula was identified and ligated. On the $12^{th}$ postoperative day, esophagography showed neither stricture nor leakage.

Diffuse esophageal spasm(DES) is a rare disease seen in 4% of all patients studied in an esophageal motility laboratory, and its diagnosis and surgical management is still controversial. Recently, we treated two patients by extended esophageal myotomy for diffuse esophageal spasm which was diagnosed by the clinical symptoms of patients, esophagoscopy, esophagography, and esophageal manometry. The successful result of treatments was proved with subsidence of previous clinical symptoms(dysphagia and chest pain), postoperative esophagography and esophageal manometry. We present the results together with the review of literatures.
