The risk of foreign body by small button-disc battery in children has been increasing because the batteries are widely used in electronic device and plaything and easily contact with children. Foreign body of mercury type button-disc battery, when lodged in the esophagus, leak a caustic solution which causes a rapid necrosis of esophageal mucosa. So it should be removed immediately when the radiologic diagnosis is made. We experienced a case of esophageal foreign body by mercuric disc battery in a 14-month-old male. This case will be discussed with literature review.

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.

Purpose : Childhood accidents have been increasing recently. Accidents rank as the leading cause of childhood mortality and morbidity. We performed this study to evaluate the causes of childhood accidents. Methods : The authors analysed retrospectively the medical records of 6,410 cases of childhood accidental injuries who visited the emergency room of Asan Medical Center from January 1990 to December 1999. Results : The most common type of accidents was trauma which accounted for 5,038 cases of the total accidents, followed by falls, burns, foreign body aspiration, and poisoning. The most common age of foreign body aspiration was under two years old and the male to female ratio was 2 to 1. The most common site of foreign body aspiration was the esophagus and the stomach, followed by the respiratory tract. In airways, the right and left main bronchus were the most common site for foreign body aspiration and were accompanied by the highest mortality. The most common foreign body in the gastrointestinal tract and respiratory tract were coins and peanuts, respectively. Conclusion : The most common cause of accidents was trauma, followed by falls, burns, foreign body aspiration, and poisoning. The incidence of foreign body aspiration and poisoning is increasing in infants. In cases of foreign bodies in airways, proper management is needed because of the high mortality rate.

We have recently removed five interesting foreign bodies successfully. Case 1. A broken tracheostomy outer cannular tube in the right main bronchus of a 7 year old boy. Case 2. An acupuncture needle in the trachea of a fifty-one year old man. Case 3. A fish hook with thread in the second isthmus of esophagus of a 10 month old girl. Case 4. An opened safety pin (sharp point toward cephalad) in the third isthmus of esophagus of a sixteen year old boy. Case 5. A big lead bullet which went through soft tissue below right mastoid tip and lodged at the mid-point between right mastoid process and foramen magnum(skull base) of a twenty year old boy, was removed surgically uneventfully.

Foreign bodies in the airway are very import-tant and not uncommon conditions in the field of E.N.T., and practically there are many reports of them. Occasionally, it can be followed by some pulmonary complications and technical difficulty to remove. Therefore, foreign body in the trachea-bronchial tree is serious and, on occasion, fatal. Recently, the authors experienced 7 interesting cases of foreign bodies in the airway and a brief review of literature was made. Case 1. (1 year old male): A bit of walnut was coughed out spontaneously. Case 2. (2 years old male): A bit of raw chestnut was removed from the right main bronchus. Case 3. (21 Years old male): A pushpin was removed from the left main bronchus. Case 4. (1 year old male): A kind of bean was removed from the right main vronchus. Case 5. (4 years old male): A coiled steel spring (1.1cm$\times$2cm) was removed from the subglottic region. Case 6. (5 years old female): A shell of pine nut which had been impacted in the wall of right main bronchus was removed during right middle and lower lobectomy. Case 7. (2 years old male): A metal nail was removed from the rightposterior basal segmental bronchus during right lower lobectomy.

The authors performed clinical analysis on 124 cases of airway foreign bodies in children treated by ventilating bronchoscopy at Severance hospital from 1980 to 1992. The results were as follows ; 1) The most of the cases were below age of 2.(71%) 2) Nuts were the most common airway foreign body.(52%) 3) The grequent loci of airway foreign body were left main bronchus(49 cases), right main bronchus(38 cases), trachea(17 cases) in order. 4) The most common chest X-ray findings were obstructive emphysema.(60%) 5) By duration of lodgement in the airway, 82 cases(66%) were removed within 1 week and 16 cases(13%) over 30 days. 6) All of 124 cases were successfully treated by ventilating bronchoscopy without serious complications. In conclusion, the left bronchus was the most common location of foreign bodies and it would be advisable to avoid nuts for snack below the age of 2.

Foreign bodies of the upper aerodigestive tract in the pediatric population are a common occurrence. However, despite significant advances in prevention, first aid and endoscopic technology, they remain a diagnostic and therapeutic challenge. Early diagnosis is the key to successful and uncomplicated management of these accidents. An orderly and systematic approach to these patients including a careful history, physical exam and radiographic studies is detailed in this review.

Dsysphagia or difficulty in swallowing is a symptom wich indicates the presence of disease or dysfunction. Because the cause & the original site are variable, it is significant to study the clinicostatistical analysis on 133 cases with complant of dysphagia during the last one year in the department of Otolaryngology, College of Medicine, Seoul National University. The results are as follows; 1) Among the total O.P.D. patients (6313 cases), patients complaining the dysphagia are 2.1%. 2) Male to female sex ratio is 1. 3 to 1, slightly predominent in male and average are 35.7 years. 3) The duration of chief complaint is about 251 days in average, but excluding the 8 cases with more than year of symptom, it is about 40 days. In detailed analysis of the duration; 67 cases (50.4%) occurred within 1 weak: 24 cases (18.0%), 1 week to 1 month: 34 cases (25.6%), 1 month to 1 year: 8 cases (6.0%), more than 1 year. 4) As to the site of origin, the oropharyngolaryngeal origin 106 cases (76.7%) are 4 times as many as the esophageal origin 27 cases (20.3%). 5) As to the etiological classification: inflammation 67 cases (50.4%), tumor 28 cases (21.0%), corrosive agent 14 cases (10.5%), foreign body 11 cases (8.3%) in order. 6) As to the disease entity: pharyngitis and tonsillitis 42 cases (31.6%), stomatitis 14 cases (10.5%), corrosive esophagitis 14 cases (10.5%), laryngeal tumor 12 cases (9.0%), peritonsillar abscess 9 cases (6.8%), esophageal foreign body 7 cases (5.2%), tongue tumor 7 cases (5.2%), tonsillar tumor 6 cases (4.5%), (pharyngeal foreign body 4 cases (3.0%)in order.
