Intrathoracic cyst was considered rare entity but one of the important diseases in the field of thoracic surgery. Authors had experienced 17 cases of intrathoracic cysts that were treated in the department of thoracic and cardiovascular surgery of Pusan NationalUniversity Hospital for 10years from January, 1983. to December,1992. The summary is as follows: Their age distribution was from 2 years and 9 months to 59 years of age, mean age 27.2 years. There were 8 males and 9 females. The type of intrathoracic cyst was 10 cases of Bronchogenic cyst, 2 cases of Pericardial cyst and 4 cases of Non specific cyst. The anatomical locations of intrathoracic cysts were 6 cases of anterior mediastinum, 2 cases of middle mediastinum, 3 cases of posterior mediastinum and 6 cases of lung parenchyme. The most common symptom was coughing and followed by general weakness, fatigue, chest pain & discomfort and hemoptysis and 6 patients were asyptomatic. The successful complete removal was done at all cases.Postoperative complications were developed in 5 patients but there was no case of hospital mortality.

We managed 80 patients of bronchiectasis from Jan.1983 to Dec.1992 admitted to the department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital. We evaluated clinically these patients and summarized as follows. Alpha-hemolytic streptococcus was the most commonly found bacterial strain in microbial study. For the conservative treatment, first generation cefalosporins, aminoglycosides and ampicillin were used as antibiotic therapy in this order of frequency. The preoperative final diagnosis was made by bronchography and HRCT. In the image study saccular type bronchiectasis was 47.1%, cylindrical 27.5%, mixed 17.6% and varicose 7.8%. Anatomically left side involvement was more frequent than the right as 61.2% to 38.8% and the most commonly invading lobar area was left lower. Reversibility after conservative treatment for all the types of bronchiectasis was 66%. Surgical treatment were done in 50 cases, among these left lower lobectomy was 38.0%, left lower lobectomy with ligular segmentectomy 22.0%, right middle and lower bilobectomy 16.0%, right lower lobectomy 10.0%, left pneumonectomy 10.0%, right pneumonectomy 4.0%. In 10 cases, there remained some lesion in the other sites of lung parenchyme after first attempt surgical resection because the distribution of lesion is too broad to resect out in single thoracotomy hoping improvement by medical management.

Recently, the trauma patients have been markedly increasing due to the vast increase of traffic accident, industrial disaster, incidental accident and violence. The authors have analysed of 22 patients of thoracic injuries combined with abdominal injuries and summarized as follows. The ratio of male to female was 3.4:1 and their age distribution was from 5 years to 68 years and mean age was 34.4 years. The etiologies of injury were traffic accident, stab wound, fall down and violence. Associated injuries were fractures, bowel perforation, kidney rupture, head injury, liver laceration, spleen rupture and so forth. The modes of treatment were closed thoracostomy, repair of diaphragm, ruptured bowel repair, explo-thoracotomy, splenectomy, hepatic lobectomy in this order of frequency. The postoperative complications were atelectasis, wound infection, pneumonia, empyema, acute renal failure, respiratory failure and bleeding. The mortality rate was 13.6% [3/22 and the causes of death were respiratory failure 1 case, acute renal failure 1 case and hypovolemic shock 1 case.

식도의 기저세포양 펀평세포암 -1례 보고-

박서완,정성운,이형렬,Park, Seo-Wan,Jeong, Seong-Un,Lee, Hyeong-Ryeol 대한흉부심장혈관외과학회 1996 Journal of Chest Surgery (J Chest Surg) Vol.29 No.9

기저세포양 편평세포암(basaloid squamous carcinoma)은 상부 기도소화기계에 발생하는 드문, 악성도가 높은 암종으로 침습성 편평세포암(invasive squamous carcinoma)이나 상피내암(carcinoma in situ) 형태의 편평상피암종성분과 밀접하게 혼재되어 있는 기저세포앞종성분(basaloid component)으로 특징 지워질 수 있다. 이런 조직학적 특성에도 불구하고 식도의 선양 낭성암(adenoid cystic carcinoma)이나 선양 낭성 분화를 보이는 암종(carcinoma with adenoid cystic differentiation)과 혼동되어 왔으나, 순수 선양 낭성암은 악성도가 기저세포양 편평세포암보다 낮아감별 진단이 중요하다. 기저세포양편평세포암의 임상적 경과는 식도의 편평세포암과 유사하다. 본 병원에서는 60세 남자의 식도 중간 113 부위에 발생한 기저세포양 편굉세포암을 수술치험하였다. Basalold squamous carcinoma (BSC) is a rare, aggressive neoplasm of the upper aerodigestive tract or esophagus. It is characterized by a biphasic pattern in which basaloid tumor is intimately associated with a neoplastic squamous component which can be either Invasive r in situ. Despite its characteristic histologic appearance, the BSC of the esophagus has been confused with esophageal neoplasm variously reported as adenoid cystic carcinoma or carcinoma with adenoid cystic differentiation Their distinction is important because genuine adenoid cystic carcinoma is much less as- gressive than BSC. The biologic course of BSC is similar to that of the more frequent squamous cell carcinoma of the esophagus. We have experienced a case of BSC of the esophagus in a 60-year-old male patient. The lesion was located in the middle third of the esophagus. The patient was treated with surgery followed by radio- therapy.

후천성 기관식도루는 드문 질환이 지만 생명을 위협하는 병변이며 원인중에는 cuff가 있는 tube를 삽관하여 부적절한 관리하에 장기간 인공호흡기 치료를 한 환자에서 발생하는 경우가 가장 많다. 손상의 기전은 cutt에 의해 기관벽에 압력이 가해져서 허혈성 손상과 더불어 염증성 반응이 더해져 압박된 식도와 비정상적 교통이 생기는 것으로 여겨지고 있다. 환자는 25세된 임산부로 중이염의 합병증으로 세균성 뇌막염이 발생하여 장기간의 인공호흡기 치료중 갑작스런 피하기종과 종격동기종이 발생하여 기관지 경과 CT를 이용해 기관식도루가 발생 했음을 확인후 본과에서 수술적 치료를 시행하였다. 수술은 자동봉합기로 기관의 손상부위를 봉합하고 식도 부위는 vlcyl과 Prolene으로 내외층을 단순봉합하였으며 기관과 식도사이에 흉쇄유돌근 절편을 끼워 넣었다. 수술 후 10일째 식도조영술로 기관식도룬가 완전복구되고 식도기능이 정상임을 확인하였으며 퇴원 후 추적조사결과 환자는 별 문제없이 잘 지내고 있다. Acquired tracheoesophageal fistula, a life threatening lesion, is rare but occurs most frequently alter prolonged mechanical ven ilation using a cuffed endotracheal tube. The mechanism of injury seems to be ischemia and inflammation of compressed trachea and esophagus by cuffed endotracheal tube. The patient was a 25 years old pregnant woman who was on prolonged mechanical ventilation for bacterial meningitis secondary to untreated otitis media. 40 days after mechanical ventilation, sudden subcutaneous empysema and pneumomediastinum ocurred and these were due to tracheoesophageal fistula. It was diagnosed with bronchoscopy and CT We performed tracheal repair with TA 60mm stapler and esophageal repair by interruted two layer suture with 410 vicryl and 510 prolene. A flap of sternocleidomastoid muscle was inserted between trachea and esophagus. Postoperative course was uneventful and the result of operation was acceptable by esophagography.

상대정맥 증후군을 가진 49세 여자환자에 spiral vein graft를 이웅한상대정맥 우회로 조성술을 실시 하여 좋은 결과를 얻었다. 이 복합 나선형 이식 편은 폐쇄된 상대정 맥을 우회하여 우측 무명동맥과 우심 이간에 이식되었다. 이식편은 환자 자신의 대복재정 맥을 세로로 절개하여 스탠트에 나선형으로 감은 후 정맥의 가장자리들을 봉합하여 하나의 큰직경을 가진 도관으로 만든 것이다. 환자는 증세 호전되었고 수술 후 21일째 합병증 없이 퇴원하였다. A 49-year-old female patient who had obstruction of superior vents cave(SVC) with SVC syndrome was successfully managed by bypass operation of superior vents cava with spiral vein graft. A composite spiral vein graft was placed between the right innominate vein and the right atrium to bypass the occluded SVC. The graft was constructed from the patient's own saphenous vein, which was split longitudinally and wrapped around a stent in spiral fashion and the edges of the vein were sutured together to form a large autogenous conduit. The patient was relieved o SVC obstructive symtoms and signs and discharged 21 days postoperatively without any complication.
