Five cases of esophageal cancer developed at the site of esophageal lye stricture were reported. Duration of lye stricture was between 13 and 40years, and all 5 cases had taken normal diet without appreciable troubles after recovery from the acute stage of burn till the suspected onset of esophageal malignaney. Outstanding symptoms of this grave condition were rather acute progressive dysphagia and frequent episodes of esophageal foreign bodies, Diagnosis could be confirmed easily by endoscopic biopsy in suspected eases, and all were epidermoid carcinoma histopathologically. Curative resection of this condition was made in neither of the cases, and their prognoses were more grave than other esophageal malignancies in our experience. The development of esophageal carcinoma at the site of corrosive esophagitis with resulting benign stricture has now been suspected as a cause and effect relationship between these two conditions, and Kiviranta: stated that the incidence of esophageal cancer in patients with lye stricture of longer duration is a thousand times higher than normal population. During last one decade the authors experienced 5 cases of esophageal carcinoma developed at the site of lye stricture of the esophagus among about 350 cases of lye burned esophagus at the Department of Thoracic & Cardiovascular Surgery, the National Medical Center in Seoul, Korea. In Korea they still use lye as a detergent in rural area, and there are still many persons ingesting lye for suicidal attempt or on accident. Lye stricture of the esophagus is, therefore, the most common esophageal disease needing surgical procedures, and the authors believe that there will be much more eases of lye stricture complicated by esophageal eareinoma repoted in near future in this Country.

Purpose: The optimal method for intracorporeal esophagojejunostomy remains unclear because a purse-string suture for fixing the anvil into the esophagus is difficult to perform with a laparoscopic approach. Therefore, this study aimed to evaluate our novel technique to fix the anvil into the esophagus. Materials and Methods: This retrospective study included 202 patients who were treated at our institution with an intracorporeal circular esophagojejunostomy in a laparoscopy-assisted total gastrectomy with a Roux-en-Y reconstruction (166 cases) or a laparoscopy-assisted proximal gastrectomy with jejunal interposition (36 cases). After incising 3/4 of the esophageal wall, a hand-sewn purse-string suture was placed on the esophagus. Next, the anvil head of a circular stapler was introduced into the esophagus. Finally, the circular esophagojejunostomy was performed laparoscopically. The clinical characteristics and surgical outcomes were evaluated and compared with those of other methods. Results: The average operation time was 200.3 minutes. The average hand-sewn purse-string suturing time was 6.4 minutes. The overall incidence of postoperative complications (Clavien-Dindo classification grade ${\geq}II$) was 26%. The number of patients with an anastomotic leakage and stenosis at the esophagojejunostomy site were 4 (2.0%) and 12 (6.0%), respectively. All patients with stenosis were successfully treated by endoscopic balloon dilatation. There was no mortality. Regarding the materials and devices for anvil fixation, only 1 absorbable thread was needed. Conclusions: Our procedure for hand-sewn purse-string suturing with the double ligation method is simple and safe.

The most common surgical procedure used to manage tracheoesophageal fistula is the primary anastomosis of the esophagus. However, in the case of failed anastomosis, replacing the esophagus with another organ is necessary. We performed two procedures of colon interposition after failure of tracheoesophageal fistula repair. In those cases, stomach replacement was not possible because of a failed Ivor Lewis operation in one case and duodenal atresia in the other.

Minimally invasive surgery (MIS) has several advantages over conventional open surgery. Less pain, less morbidity, early recovery and better cosmetic outcomes are well-known benefits of MIS. However, indications of MIS are highly dependent on the experience of surgeon and the disease status, In the benign diseases with less surgical complexity, MIS can be performed relatively and safely. However. in advanced malignant diseases which require more complex surgical manipulation, the of patients and the principles of oncologic surgery should be considered before the selection of surgical methods, MIS would be performed more and more with aid or technologic advancement. However, long-term result with equivalent oncologic outcomes to open surgery is necessary to be one of standard surgical treatments in thoracic surgery.

폐 형성에 활성적인 또는 억제적인 기능을 갖고 있다고 알려져 있는 FGF-7 성장인자, BMP수용체 II, 그리고 TGF-$\beta$ 수용체 II 유 전자의 비정상 발현이 폐기포 생성에 관여하는지를 각각의 단일성 클론 항체를 사용하여 수술로 절제된 자연기흉 환자의 폐기포 조직들을 면역조직염색 방법으로 염색하여 관찰하였다. 대상 및 방법: 재발성 또는 지속성 기흉으로 흉강경 또는 개흉술로 폐기포 절제술을 실시한 환자들을 대상으로 하였다. 총 31명의 환자로 15세에서 39세까지 연령분포를 보였으며 남자 30명, 여자 1명이었다. 폐기포 절제는 비디오흉강경이나 소절개개흉술을 통하여 폐기포벽의 손상을 가하지 않게 주의하면서 비디오흉강경용 스태플러(Endo GIA stapler)를 이용하여 절제하였으며 가능한 원형을 유지하여 신선한 상태로 포르마린에 고정하여 면역조직화학적 연구를 위한 표본을 만들었다. 폐기포 조직 슬라이드를 단일클론성 항 TGF-$\beta$ 수용체 II, BMP수용체 II 그리고 FGF-7인자 항체를 이용하여 면역조직학적 염색방법으로 관찰하였다. 결론: 전체 환자 31명중 TGF-$\beta$ 수용체 II항체에 양성 반응을 나타낸 환자수는 모두 24명이었다. 이들 중에는 18명이 강한 양성 반응을 보였고, 6명이 약한 양성 반응을 보였다. 면역조직화학적 염색 결과를 고배율 현미경으로 살펴보면, TGF-$\beta$ 수용체 II의 염색이 기흉과 정상 폐조직 경계 부위에서 특히 강하게 염색됨이 관찰되었다. 이에 반하여, BMP수용체 II 그리고 FGF-7인자의 항체를 이용한 면역조직학적 염색 결과는 모든 환자의 조직들에서 음성으로 관찰되었다. 절론: 폐 조직이 형성될 때, 억제유전자의 역할을 담당하고 있다고 알려진 TGF-$\beta$ 수용체 II의 발현이 증가되면서 폐기포가 생성될 수 있다는 가능성을 제시하였다. 이번 결론은 면역조직학적 염색 실험 결과만으로 밝혀진 사실임으로 좀 더 체계적인 분자생물학적 인 연구가 요구된다.

The repair of esophageal atresia with a long gap continues to pose difficulties for the surgeon. There is a general agreement that the child's own esophagus is the best, however, primary repair is not always possible. Foker JE et al. (1997) developed a technique of esophageal lengthening using external traction sutures. We successfully treated one patient with a 4.5cm gap esophageal atresia (4 vertebral spaces) using the external traction suture technique.

Esophageal perforation is one of the most grave prognostic problems among thoracic and general surgical emergencies which necessitate urgent operative measures. In Korea,there are still many persons ingesting lye for suicidal attempt and thoracic surgeons in Korea have more chances to deal with lye burned esophagus with or without instrumental perforation than those in Western countries. Main cause of esophageal perforation in Korea is instrumental perforation in patients with lye stricture of the esophagus during diagnostic endoscopy or therapeutic bouginage. Other causes are corrosion of the esophagus due to ingestion of caustic agents, pathologic perforation, surgical trauma, stab wound and spontaneous rupture of the esophagus in our series. Therapeutic measures are various,and depend on duration of perforation, severity of its complications, pathology of perforated portion of the esophagus and degrees of inflammation at the point of perforation. The most important therapeutic measures are prevention of this grave condition during esophagoscopy, bouginage and surgical procedures on lungs and mediastinal structures and to make early diagnosis with prompt therapeutic measures. During the period of January, 1959, to December, 1971, the authors experienced 65 cases ofesophageal perforation including acquired esophagorespiratory fistula at Dept. of Chest Surgery, the National Medical Center in Seoul, and obtained following results in the series. 1. Female were 35 cases, and peak age incidence was 2nd and 3rd decades of life. 2. Among 65 cases, 43 were corrosive esophagitis or benign stricture of the esophagus due to caustic agents, 7 were patients with esophageal cancer. and there were 5 cases of esophageal perforation developed after pneumonectomy or pleuropneumonectomy. 3. Causes of perforation are instrumental perforation in 45, acute corrosion in 7, pathologic perforation in 7, surgical trauma in 3, stab wound in 2 cases, and one spontaneous rupture of the esophagus. 4. Most frequent sites of esophageal perforation were upper and mid thoracic esophagus, and 8 were cases with cervical esophageal perforation. 5. Complications of esophageal perforation were mediastinitis in 42, empyema or pneumothorax in 35, esophagorespiratory fistula in 12, retroperitoneal fistula or abscess in 5,pneumoperitoneum in 3, and localized peritonitis in 1 case. 6. Cases with malignant esophagorespiratory fistula were only 3 in the series which is predominant cause of acquired esophagorespiratory fistula in Western countries. 7. Various therapeutic measures were applied with mortality rate of 27.7% in the series. 8. In usual cases early treatment gave better prognosis, and least mortality rate in cases with perforation in mid thoracic esophagus. 9. Main causes of death were respiratory complications,acute hemorrhage with asphyxia, and septic complications. 10. Esophageal perforation developed after pneumonectomy gave more difficult therapeutic problems which were solved in only 1 among 5 cases.

Treatment of patients with esophageal carcinoma remains disappointing. Fewer than 20% *of patients with esophageal carcinoma treated with curative intent by surgery and radiation therapy will be alive at 5 years. Fifty five patients underwent treatment for carcinoma of the esophagus and cardia which retrospective clinical study done between January 1983, and December, 1989 in Department of Thoracic and Cardiovascular Surgery, National Medical Center, Seoul, Korea. There were 48 men. 7 women and the mean age was 56.2 years[range, 38 to 78 years]. The most frequent preoperative findings included dysphagia[46 cases], weight loss[33 cases] and substernal pain[19 cases]. 19 cases[34.5%] were underwent resectional surgery, which was total esophagectomy with esophagogastrostomy[ 5 cases], with colon interposition[3 cases], lower esophagectomy with esophagogastrostomy [10 cases], with total gastrectomy and esophagojejunostomy [1 case]. The operative mortality was 15.8%[3/19] and causes of death were respiratory failure in 2 cases, and 1 case of sepsis. Palliative procedures, such as feeding gastrostomy and jejunostomy[14 cases], bypass surgery without resection[ 4 cases], radiation therapy[ 3 cases] were done.
