This patient was an 53-year-old man who had undergone Sengstaken-Blackmore tube insertion for esophageal varix bleeding. Two days after Sengstaken-Blackmore tube insertion, he developed severe left hemothorax and was transferred to our hospital. The esophagoscopic findings revealed a large perforation lengthening 8-cm in the intrathoracic esophagus. A left thoracotomy was performed 33 days after the injury due to repeated varix bleedings and poor conditions. An 8-cm longitudinal perforation of the intrathoracic esophagus with gross suppurative empyema was found. Primary repair and esophageal exclusion was performed 2cm proximal and distal to the perforation, using rows of nonabsorbable staplers(TA stapler 60 $\times$ 4.8) and large bore thoracostomy tubes were placed for local drainage. Six days after intrathoracic esophageal exclusion, an esophagogram revealed a leakage at just above the proximal stapling site. A cervical esophageal exclusion was performed using the same method. One hundred thirty seven days after exclusion operation for the intra-thoracic esophageal perforation, the patient was able to eat per orally without any secondary esophageal reconstructive surgery.

Bursting stress in anchorage zone of post tension girder can be estimated based on Guyon's equation. The major parameters in calculating bursting stress are prestressing force and the distance ratio between concrete edge and anchorage plate. Although Guyon's equation can be applied to calculate bursting stress for rectangular typed as well as circular typed plate, there is some limitation of accuracy due to 2 dimensional analysis. Therefore this study is proposed to suggest a bursting stress equation based on 3 dimensional finite element method.

카세트식 이동식부탄연소기의 사고는 과열에 의한 화재뿐만 아니라 접합용기의 파열에 따른 피해가 더 큰 위험성을 내포하고 있다. 접합용기의 파열원인은 화재에 의한 파열과 접합용기 장착 불량에 의한 가스누출로 화염에 의한 파열, 그리고 과대 조리기구를 사용하여 조리기구 및 화염에서 발생되는 열이 접합용기에 전달되어 온도상승에 따른 파열로 구분된다. 현재 카세트식 이동식부탄연소기의 조리기구 크기에 따라 과열에 따른 정확한 검증이 부족하며, 사용자에게 사용장소와 조리기구외 크기만 권고하고 있어 이에 대한 자료가 필요하다. (중략)

흉부 둔상에 의한 기도와 식도의 동시적 파열상은 매우 드물게 발생되고 있다. 그러나 최그들어 고속 교통사고의 증가와 환자에 대한 응급체계의 발전으로 점차 치험 보고례가 증가되고 있다. 저자들은 흉부의 둔상에 의하여 기도와 식도에 종적으로 긴 파열상을 입은 환자 2례의 치험을 보고한다. 1례는 이전 병원에서 시행한 기관식도 재건술이 실패한 상태에서 전원되어와 2차적으로 식도절제 및 기관재건술을 실시하였으나 사망하였고. 다른 1례는 식도절제 및 기도재건술로 합병증이 없이 생존하였다.

In this paper, an unbonded post-tensioning anchorage for a single-stranded wire that allows more efficient stress distribution in the post-tensioned anchorage zone was developed by using a finite element analysis using a commercial program. The stress analysis was carried out using a 3D model in the anchorage zone of the concrete member using the developed anchorage. The result of analysis ensured that the developed anchorage reduced the maximum bursting stress in anchorage zone compared to the case of existing anchorage and the location where maximum bursting stress also occurred closer to the anchorage. Bursting force was calculated using AASHTO, modified $M{\ddot{o}}rsch$ and Stone. As a result, it was concluded that an effective reinforcement design of the anchorage zone can be designed by modified $M{\ddot{o}}rsch$.

Tracheobronchial rupture following tracheal intubation is a rare complication. We experienced a case of tracheal rupture following double-lumen endotracheal tube intubation. A 76 year old female was admitted due to coughing and chest discomfort. The operation was performed with the diagnosis of congenital broncho esophageal fistula. During the operation, accidently the main trachea was ruptured longitudinally. There was no history of surgical trauma. The ruptured trachea was repaired with prolene and monofilament absorbable sutures. The cause of tracheal rupture was suspected overinflation of the cuff. The patient was discharged from the hospital without any significant complications.

경동맥 파열은 악성 종양으로 인한 두경부 수술의 1-5%에서 발생하고 80%의 사망률과 생존자의 50%에서 신경학적 후유증을 나타낸다. 저자들은 수술전ㆍ후 방사선치료를 받은 환자 2례에서 경동맥파열을 경험하였다. 제 1례는 51세의 남자로서 후두암($T_4$NoMx)으로 후두전적출술과 6120 rad의 수술후 방사선 치료 후 좌측 악하 부위에 악성 종양의 경동맥 침윤으로 시험적 수술후 6일만에 경동맥 파열로 사망하였다. 제 2례는 51세의 남자로서 하인두암($T_3$$N_2$Mx)으로 7200 rad의 수술전 방사선치료후 악성 종양의 재발로 후두전적출술과 일측의 근치적 경부곽청술후 누공을 형성하여 수술후 14일만에 경동맥 파열로 사망하였다.

식도 결핵은 아주 드문 질환으로 연하곤란과 흉통이 가장 흔한 증상이면 다량의 토형은 드문 것으로 되어 있다. 본원에서는 다량의 토형을 동반한 식도 결핵에 의한 식도 대동맥루를 가진 환자를 지험했다. 4세 남자 환자는 다량의 토혈로 응습실을 통해 입원했다. 내원 당시 응급으로 시행한 내시경 검사상 incisor로부터 25cm 하방에 0.7 cm의 풍부한 혈관성의 육아종성 병변을 발견하고, 응급개흉술로 식도의 종양성 병변에 대해 쐐기 절제술을 시행하였다. 식도의 종양성 병변부위는 대동맥과 심게 유착되어 있었고 식도에서 대동맥쪽으로의 식도루를 이중 결찰했다. 환자는 술후 8일째 갑작스런 흉관을 통한 다량의 출혈과 구토 후 토형이 있어 응급 재 개흉술을 시행하여 대동맥파열과 식도 문합부 파열을 확인하였으나 더 이상의 교정이 불가능하여 사망하였다. 이에 문헌고찰과 함께 보고하는 바이다.

We report hereon a case of double bypass of the esophagus and descending thoracic aorta for the treatment of esophagopleural fistula and aortopleural fistula due to an infected aortic aneurysm after esophageal rupture. A 48 year old man was diagnosed as having esophageal rupture after an accidental explosion. Although he had been treated by esophageal repair and drainage at another hospital, the esophageal leakage could not be controlled and subsequent empyema developed in the left pleura. Further, bleeding from the descending thoracic aorta had developed and he was managed with endovascular stent insertion to the descending thoracic aorta. He was transferred to our hospital for corrective surgery. We performed esophago - gastrostomy via the substernal route, without exploring posterior mediastinum and we let the empyema resolve spontaneously. While he was being managed postoperatively Without any signs and symptoms of infection, sudden bleeding developed from the left pleural cavity. After evaluation for the bleeding focus, we discovered an Infected aortic aneurysm and an aortospleural fistula at the stent insertion site. We performed a second bypass procedure for the infected descending thoracic aorta from the ascending aorta to the descending abdominal aorta via the right pleural cavity. We found leakage at the distalligation site during the immediate postoperative period, and we occluded the leakage using a vascular plug. He discharged without complications and he is currently doing well without any more bleeding or other complications.
