In the treatment of the acute respiratory failure, ventilatory support with endotracheal intubation or tracheostomy is a life saving procedure in many cases but the development of postintubation tracheal stenosis is a very serious complication. Recently we have experienced one case of postintubation tracheal stenosis which occurred in the region of cuff site. Preoperative tracheogram showed a concentric stricture 3.0 cm in length located 4.0 cm proximal to the carina. Under the general anesthesia, the stenotic segment was resected and end-to-end anastomosis was performed successfully through the right posterolateral thoractomy. Her postoperative course was uneventful and the patient has remained well till now.

This is a report on four cases of bypass for esophageal stricture due to gastro-esophageal carcinoma in the Department of Thoracic Surgery, Chonnam University Hospital. Bypass was performed intrathoracal esophago-jejunostomy by a segment of jejunum. Three patients received end to end anastomosis and the other one side to end esophagojejunostomy. Postoperative results were as follow; There was no swallowing disturbance with regular diet and the patients appear to be more comfortable by bypass than gastrostomy or jejunostomy. Postoperative condition of all the patients was satisfactory because other organs were intact. However, two patients expired in 12 months and 6 months after operation by wide metastasis and the other 2 cases are living now with regular diet in 4 months and 2 months after operation.

Gastro-esophageal reflux disease (GERD) is a recurrent, long-term gastrointestinal condition characterised by the abnormal reflux of stomach contents into the esophagus. Heartburn is the most dominant symptom, which can be life long and can considerably reduce quality of life. The main goals of treatment are to alleviate symptoms and prevent relapses, esophageal stricture and adenocarcinoma. This paper presents a review comparing the effectiveness of omeprazole with Nissen fundoplication surgery for the treatment of GERD. Nissen fundoplication is more effective in controlling heartburn symptoms, healing esophagitis and preventing relapses than omeprazole. Quality of life, in terms of productivity and ability to work, is difficult to assess in the omeprazole group and, as a result, a comparison of this aspect is limited. Although fundoplication is expensive in the short term, it is more cost-effective than omeprazole. Nurses need to be aware of the effectiveness of omeprazole and fundoplication to provide patients with accurate information, which assists patients in decision making regarding treatment options.

Background and Objectives : The aim of the this study is to determine the efficacy of an external prosthesis made of ringed Polytetrafluoroethylene to prevent Postanastomotic stenosis after surgical correction of extensive tracheal defects in rabbits. Materials and Methods : Thirty rabbits were used, divided into two groups of 15 animals each. Group A rabbits underwent resection of six-ring segments of the cervical trachea and tracheal end-to-end anastomosis. The Procedure used in group B was similar to that used in group A. but the tracheal anastomosis was supported by an external ringed polytetrafluoroethylene prosthesis. After six months, rabbits were killed and tracheas were resected and then compared the postanastomotic tracheal stenosis using morphometry. Results : Anteroposterior diameter, transverse diameter, cross sectional area and intra luminal perimeter of trachea was greater in group B than group A. Also inflammatory changes of mucosa and submucosa were greater in group A than group B. Conclusion : A ringed PTFE as a external stent was effective to prevent tracheal stenosis resulting from the extensive tracheal resection and tracheal reconstruction in rabbits.

Condyloma acuminatum is an uncommon disease but there is an increased incidence reported in recent years in prepubertal children. Anal and perianal condyloma accuminatum in children may suggest sexual abuse and treatment should include the thorough social evaluation as well as medical treatment. A 25 month old girl presented with multiple sessile nodules around her anal and perianal area, Biopsy confirmed the diagnosis of condyloma accuminatum. There was no definite evidence of sexual abuse, but her father had condyloma accuminatum involving his penis. The patient's lesions were excised totally. At three week follow up there was no anal stricture but there were newly developed small lesions around perianal area. Imiquimod onit was applied for 2 weeks and the recurred lesion disappeared completely. At postoperative 5 month, the operative area was fully epithelialized without recurrence.

This paper presents a 6-bit self-calibrated D/A converter designed with current cell matrix structure. This structure is based on the current-cell matrix configuration using a regulated gate cascode current cell with 3-way switch. using from CMOS process and 5V power supply, the simulated conversion rate is 45.78MHz and the average mismatching properties among current sources are reduced to 0.02% and 0.005%, respectively when 1% and 0.5% errors of current sources are considered.

부식성 식도염에서 속발한 식도협착의 비외과적 치료법으로 사용되었던 종래의 각종 소식자를 이용한 확장술은 그 효과가 일시적이며 소아에서 시행시 많은 문제점이 있다. 근래들어 관상동맥, 요관, 대장 등의 협착에 사용되어온 balloon Catheter를 이용한 식도 확장술은 비교적 안전하고 효과적이어서 소아나 정도가 심한 식도협착의 치료에 큰 도움을 줄 수 있다. 본 교실에서는 최근 2년간 부식성 식도염 후 속발한 식도협착 6 례를 Balloon catheter 확장법으로 치료하여 아래와 같은 결과를 얻었기에 보고하는 바이다. 1) 전체 6명 중 남자가 4명 여자가 2명으로 평균 연령은 45.7세였다. 2) 부식제의 종류는 가성소다가 5명 초산이 1명이였다. 3) 협착부위는 1례가 경부식도이며 5례가 흉부식도였고 이중 1례는 다발성 협착이 였다. 4) 확장 전 식도조영사진 상 협착부위의 평균 내경은 4.3mm였다. 5) 확장술을 시행한 횟수는 2회에서 5회( 평균 3.5회 )로 확장술이 끝난 후의 평균 내경은 13.5mm였다. 5) 확장술시 3례에서 식도파열이 발생하였으나 보존적 치료법으로 치유되었다.

A fistulous communication between an esophageal traction diverticulum and the tracheobronchial tree appears to be of rare occurrence. This report reviews the feature of benign esophagobronchial fistula due to esophageal traction diverticulum. This 36-year-old female patient suffered from substernal pain, interscapular pain and severe paroxysmal coughing after ingestion of fluids. This patient was taken a diverticulectomy and partial resection of superior segment of right lower lobe. After the operation, there was no subjective symptoms, esophagobronchial fistula, leakage, stricture and diverticulum. The postoperative result was excellent.

Superficial esophageal neoplasms (SENs) are being diagnosed increasingly frequently due to the screening endoscopy and advances in endoscopic techniques. Endoscopic resection (ER) is a relatively noninvasive treatment method with low morbidity and mortality that provides excellent oncologic outcomes. Endoscopic submucosal dissection is associated with higher rates of en bloc, complete and curative resections and lower rates of local recurrence than endoscopic mucosal resection. The most serious complication of ER is stricture, the treatment and prevention of which are crucial to maintain the patient's quality of life. ER for SEN is feasible, effective, and safe and can be considered a first-line treatment for SENs in which it is technically feasible.

There are two pathogenic models of renovascular hypertension (RVH) originating from renal artery stenosis. We noted a case of a boy who had severe hypertension with atrophic left kidney, hypertrophic right kidney, a segmental stricture of the abdominal aorta, and total occlusion of the right renal artery. Due to the atrophic change of the contralateral, unclipped left kidney, this patient presented with various clinical manifestations related to both models of pathogenesis of RVH occurring at the same time. We conclude that this patient presented with the middle stage of the two RVH pathogenetic models, so called the 'one-clip, one and half-kidney model.'
