With the improvement of living standard and educational level of the people, there is an increasing awareness about the dangers of toxic substances and lethal drugs. In addition to the above, the governmental control of these substances has led to a progressive decrease in the accidents with corrosive substances. However there are still sporadic incidences of suicidal attempts with the substances due to the unbalance between the cultural development in society and individual emotion. The problem is explained by the fact that there is a variety of corrosive agents easily available to the people due to the considerable industrial development and industrialization. Salzen(1920), Bokey(1924) were pioneers on the subject of the corrosive esophagitis and esophageal stenosis by dilatation method. Since then there had been a continuing improvement on the subject with researches on various acid(Pitkin, 1935, Carmody, 1936) and alkali (Tree, 1942, Tucker, 1951) corrosive agents, and the use of steroid (Spain, 1950) and antibiotics. Recently, early esophagoscopic examination is emphasized on the purpose of determining the way of the treatment in corrosive esophagitis patients. In order to find the effective treatment of such patients in future, the authors selected 96 corrosive esophagitis patients who were admitted and treated at the ENT department of Severance hospital from 1971 to March, 1981 to attempt a clinical study. 1. Sex incidence……male: female=1 : 1.7, Age incidence……21-30 years age group; 38 cases (39.6%). 2. Suicidal attempt……80 cases(83.3%), Accidental ingestion……16 cases (16.7%). Among those who ingested the substance accidentally, children below ten years were most numerous with nine patients. 3. Incidence acetic acid……41 cases(41.8%), lye…20 cases (20.4%), HCI……17 cases (17.3%). There was a trend of rapid rise in the incidence of acidic corrosive agents especially acetic acid. 4. Lavage……57 cases (81.1%). 5. Nasogastric tube insertion……80 cases (83.3%), No insertion……16 cases(16.7%), late admittance……10 cases, failure…4 cases, other……2 cases. 6. Tracheostomy……17 cases(17.7%), respiratory problems(75.0%), mental problems (25.0%). 7. Early endoscopy……11 cases(11.5%), within 48 hours……6 cases (54.4%). Endoscopic results; moderate mucosal ulceration…8 cases (72.7%), mild mucosal erythema……2 cases (18.2%), severe mucosal ulceration……1 cases (9.1%) and among those who took early endoscopic examination; 6 patients were confirmed mild lesion and so they were discharged after endoscopy. Average period of admittance in the cases of nasogastric tube insertion was 4 weeks. 8. Nasogastric tube indwelling period……average 11.6 days, recently our treatment trend in the corrosive esophagitis patients with nasogastric tube indwelling is determined according to the finding of early endoscopy. 9. The No. of patients who didn't given and delayed administration of steroid……7 cases(48.9%): causes; kind of drug(acid, unknown)……12 cases, late admittance……11 cases, mild case…9 cases, contraindication……7 cases, other …8 cases. 10. Management of stricture; bougienage……7 cases, feeding gastrostomy……6 cases, other surgical management……4 cases. 11. Complication……27 cases(28.1%); cardio-pulmonary……10 cases, visceral rupture……8 cases, massive bleeding……6 cases, renal failure……4 cases, other…2 cases, expire and moribund discharge…8 cases. 12. No. of follow-up case……23 cases; esophageal stricture……13 cases and site of stricture; hypopharynx……1 case, mid third of esophagus…5 cases, upper third of esophagus…3 cases, lower third of esophagus……3 cases pylorus……1 case, diffuse esophageal stenosis……1 case.

Transnasal esophagoscopy allows. the upper aerodigestive tract, from the nasal cavity to the gastric cardia to be examined in the outpatients department. It is well tolerated by patient with topical anesthesia alone and no sedation or patient preparation is required. The technique is easily learned and performed in the otolaryngologist and highly cost efficient. It is a useful tool for accurate diagnosis and can be used in a variety of office-based procedures.

중소기업에 다니는 40대 중반의 남성은 얼마 전부터 종종 가슴이 화끈거리는 불쾌한 통증과 함께, 목과 가슴 사이에 복숭아씨가 걸려있는 듯한 답답함을 느꼈다. 혹시나 심장에 이상이 있는 것이 아닌지 검사를 해보았지만, 결과는 정상이었다. 이리저리 알아보다 위액이 역류하는 경우에도 비슷한 증상이 있을 수 있다는 정보를 얻고 소화기내과를 찾았고, 내시경 검사 결과 역류성 식도염 진단을 받았다.

Purpose: To evaluate the safety, efficacy and technical problems of the endoscopic balloon dilatation of esophageal anomalies in children. Methods: The medical records of 8 children treated by endoscopic balloon dilatation for esophageal anomalies over a 10-year period at Pusan National University Hospital were reviewed retrospectively. The balloon catheter (Maxforce TTS or CRE, Boston Scientific Co., USA) was positioned across the area of narrowing by direct visualization. The balloon was slowly inflated with normal saline to specified pressures for each balloon and maintained for 60 seconds and then deflated. After 60 seconds pause, the procedure was repeated with a larger sized balloon (increments of 1 mm for each subsequent dilation) till effective dilatation was confirmed by direct visualization without complications. Results: Three male and five female were included and their mean age was 4.2 years. A total of 27 (average of 3.2 per patient) dilatation were performed. Underlying diseases of patients are postoperative stricture of esophageal atresia in 3 cases, esophageal ring in 2 cases, achalasia, corrosive esophagitis and hypertensive LES in one case respectively. The size of initial dilating balloon was chosen on the basis of the diameter of the narrowing determined by endoscopy. The first dilation in patients with severe esophageal stricture was made with a 6 mm sized balloon. Complications observed were esophageal perforation and respiratory holding during the procedure in one case respectively. Successful outcome was seen in 6 patients (75%). Conclusion: Endoscopic balloon dilatation can provide a safe and effective mean of treating esophageal anomalies in children and should be considered the treatment of choice in the initial management of those cases.

Purpose: There have been a few data about esophageal length in children and previous data are improper for application to various procedures. Because of the variability in height and weight of each the individuals especially in children, measurable external parameters are needed. Methods: We measured distance from upper incisor to esophago-gastric junction using a flexible endoscope and compared these data with age, height and weight in 262 children who underwent upper gastrointestinal endoscopy. Results: The mean age was $9.0{\pm}3.6year$ (from 2 days to 16 year of age), mean height was $132.89{\pm}23.49cm$ and mean length from upper incisor to esophago-gastric junction was $33.34{\pm}5.42cm$. Correlation between distance from upper incisor to esophago-gastric junction and height was the mostly predictable indicator of the esophageal length (Pearson correlation=0.944). We propose a formula [Esophageal length=4.419+($0.218{\times}height$)] as a indicator of the esophageal length (p=0.000, $R^2=0.891$). Conclusion: The esophageal length in children and for application to various procedures can be reliably predicted by using the height.

Esophagectomy has a high morbidity rate, mainly related to pulmonary complications. The respiratory morbidity of open esophagectomy is high, ranging from 6% to 10%. This high morbidity is partially responsible for the 6∼15% mortality rate of esophagectomy. Many techniques of esophagectomy without thoracotomy have been described since the initial report of Orringer and Sloan. Endoscopic microsurgical dissection of the esophagus was clinically introduced in 1989. Endoscopic microsurgical dissection of the esophagus was developed as a minimally invasive procedure that avoids thoracotomy and provides precise vision during the operation in order to reduce mediastinal trauma and to improve the peri- and post-operative situation. A 20 year-old women who accidentally swallowed about 150 cc of glacial acetic acid underwent an esophagectomy using the operating mediastinoscopy, cervical esophagogastric anastomosis, pyloromyotomy, and feeding jejunostomy tube placement for esophageal stricture. The postoperative course was uneventful and the patient was discharged on the 17th postoperative day. Our clinical experience shows that endoscopic microsurgical dissection of esophagus is a safe and feasible method because it offers excellent optical control and enables the surgeon to operate in a minimally invasive manner.

Esophageal hemangioma is an extremely rare benign tumor that causes dysphagia and massive upper gastrointestinal bleeding. Although certain abnormalities seen on a barium swallow esophagography or at endoscopy may suggest an esophageal hemangioma, a contrast CT and radionuclide angiography using a blood-pool radiopharmaceutical can characterize the intense vascularity of the tumor. We experienced the ase of a 7$\times$7$\times$3.5 cm in size giant cavernous hemangioma of the lower 1/3 of esophagus in a 40 year old man. A mural cavernous hemangioma was diagnosed with a barium swallowed esophagogaphy, endoscopy, and a contrast CT. It was treated successfully by transthoracic esophagectomy including the tumor and esophagogastrostomy.
