Esophageal perforation tend to occur more frequently today because of the increased use of therapeutic and diagnostic endoscopy. Even the slightest trauma to the esophageal can be fetal. Thus, esophageal perforation carries a very high mortality and morbidity unless early diagnosis and prompt therapy are instituted. We have had two cases of esophageal perforation associated with periesophageal abscess due to esophagoscopy after removal of foreign body with good results. Therefore these two cases of esophogoscopic esophageal perforation are reported with a review of the literature.

후두암 및 하인두암의 광역절제후 결손된 하인두 및 경부식도의 재건방법에는 여러 근피판, 인두위 문합이나 유리공장이식술과 같은 소화장기의 이용 및 전박유리피판술 등이 있다. 저자들은 1985년부터 1994년까지 10년간 세브란스병원에서 후두 및 하인두암으로 수술적 치료를 받은 예중 인두위문합술로 재건한 7례, 유리공장이식술로 재건한 9례, 전박유리피판술로 재건한 7례의 치료성적을 후향적으로 고찰하여 하인두 및 경부식도의 재건에 사용할 수 있는 술식들의 치료결과 및 장단점을 알아보고자 하였다. 피판의 생존은 세가지 술식 모두에서 양호하였으며 구강을 통한 식이섭취가 전례에서 가능하였다. 발생한 합병증으로는 인두피부누공, 문합부위의 협착 등이 있었으며 보존적인 방법으로 치유가 가능하였다.

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.

Background : Primary malignant tumors of the trachea are extremely rare entities and account for a mere 0.1 per cent of all malignancies of the respiratory tract. Because of vague localizing signs, symptoms and a usually negative routine chest film, the patients with tracheal tumors are often treated for asthma or chronic obstructive pulmonary disease for considerable period of time before correct diagnosis. Method : We have made a review of the 17 cases of primary tracheal tumors in recent 15 years. We reviewed the clinical features including history of smoking and respiratory symptoms, the official readings of initial routine chest film, the cytologic examination of sputum, the time of delay in diagnosis, and the response according to the therapeutic modalities. Results : Eight out of 9 patients with squamous cell carcinoma(SCC) were above 50 years old, five out of 6 patients with adenoid cystic carcinoma(ACC) were below 50 years old. The most common location of primary tracheal tumors was the upper one-third of trachea in 8 cases(47%). The most frequent symptoms were dyspnea in 13/17 cases(76%) and then stridor or wheezing, cough. and sputum in order. The routine chest roentgenographic examinations were not helpful to diagnose tracheal carcinoma and the cytologic examinations of sputums were helpful to diagnose tracheal carcinoma in only one case with adenocarcinoma. The mean times of delay in diagnosis of patients with sec and ACC were 5 months and 24.9 months respectively. We had bronchial asthma in 8 cases(47%) and tracheal tumors in 4 cases(23%) as initial clinical impression. Conclusion : We would like to perform more comprehensive diagnostic tools(high KVP technique, the fibroptic bronchoscopic examination, chest CT scan etc.) in patients who had the suggestive points for the tracheal tumorse(1. unexplained hemoptysis or hoarsness, 2. inspiratory wheezing or stridor, 3. wax and waning of dyspnea according to changes of position, 4. progressive asthmatics unresponsive to antiasthmatic therapy) and radical resection of tumor or external radiation therapy with curative aim as possible.

Purpose: To resolution of A hospital-handmade modification double tilt angle immobilization system (DTAB immobilization system) and to report the clinical results of it. Material and Methods: It was developed in conjunction with the breast board for patients unable to achieve and maintain the desired uncomfortable respiration and position of set-up needed in the treatment of RT (This custom design provides an alternative to accomplishing this desired head angle needed to relax position treatment area, realizing that the lenses totally protected eye-ball out) By using the angled breast board and SBDD(small bowel device), reproducibility of set-up and patient comfort were addressed throughout the simulation, computed tomography planning and treatment process. Results: Usually patients the error range-within 5 mm. When use of Aqua patients error range-within 3 mm. Conclusion: It was constructed in tandem with a unique custom-built double tilt angle board (DTAB). It was designed to eliminate clinical set-up problems with head immobilization and instability during treatment, thus providing for a more comfortable head rest for the patient.

방사선치료를 하는데 호흡을 다루는 문제는 매우 중요하다. 호흡으로 인한 인체의 움직임은 종양, 정상조직의 위치 등을 변화시킴으로써 표적체적 설정을 다루는 ICRU definition에 영향을 미칠 뿐만 아니라 일반적인 방사선치료의 단계별 과정에 큰 영향을 끼친다. 본 연제에서는 방사선치료의 과정 중 호흡을 고려한 영상획득, 방사선치료계획, 정도보증 등 주로 의학 물리적 관점에서 세부적으로 다루어야 할 문제들은 논외로 하고, 환자의 호흡을 모니터하고 다루어 호흡에 따른 맞춤치료를 하는 방법들을 개관해 보고자 한다. 또한, 호흡을 다루는 각각의 방법에 따른 임상적 고려사항들에 대해서도 언급하고자 한다. 각각의 기관에서 호흡을 고려한 고정밀 방사선치료를 시행하는데 있어 적절한 전략 및 프로토콜을 세우고, 이를 환자를 대상으로 정확하게 수행하기 위해서는 호흡이 방사선치료 전반에 미치는 영향을 각각의 단계별로 정확하게 이해하는 것이 선행되어야 할 것이다.

The Silicone tracheal T-tube was designed to maintain an adequate tracheal airway as well as to provide support in the stenotic reconstituted or reconstructed trachea. This report is our experiences with using silicone T-tube which were successfully used to two cases with extensive laryngotracheal trauma, and one case with decannulation difficulty for 9 months. Authors strongly believe that silicone T-tube is an excellent device out of consideration for our experienced cases, though many techniques have been applied for the treatments of tracheal problems.

Purpose: To evaluate the palliative effect of endobronchial brachytherapy (EBB) for patients with lung cancer that previously received external beam radiotherapy (EBRT). Materials and Methods: From July 1992 to May 2003, 29 patients with a recurrent or persistent lung cancer were treated with palliative EBB at our institute. EBB consisted of three fractions (once a week) of a dose of 5 Gy using the high dose-rate remote afterloader. Symptomatic improvement was assessed subjectively, and patients were divided into two groups according to whether symptoms were improved or not. Factors such as age, performance status, duration from EBRT to EBB and the location of the tumor were compared between the improved and unimproved groups of patients. Results: Overall symptomatic improvement was found in 27 out of 52 symptoms (52%). Improvement as to the type of symptoms was seen in 41 %, 50%, 82% and 33% of patients with cough, dyspnea, hemoptysis, and obstructive pneumonia respectively. The rate of improvement of hemoptysis was more than that of cough (p<0.05). The median time to symptom relapse was 5 months. The improved patient group (n=17, 59%) had a better performance status and longer duration from EBRT to EBB than the unimproved patient group (p<0.05). Lesions located in the distal trachea and/or main bronchus were found more frequently in the improved group of patients than in the unimproved group of patients, but the difference was not statistically significant (p=0.06). Fatal complications developed in two patients (7%), which were a hemoptysis and bronchopleural fistula respectively. Conclusion: Symptom improvement was found in 60% of patients after EBB and improvement was maintained for 5 months. Palliative EBB, even when EBRT was given previously, can be effective for a patient that has an endobronchial symptom, such as hemoptysis, and for a patient with good performance and a long duration from previous EBRT to EBB.
