Tracheostomy is one of the oldest surgical procedures in medical history. The indications for a tracheostomy include the relief of an upper airway obstruction, long-term mechanical ventilation, and decreased airway resistance to help wean the patient from mechanical ventilator support. Unfortunately, tracheostomy is also associated with a number of problems including, bleeding, infection, pneumothorax, and tracheal stenosis. A pneumothorax is an uncommon complication of a tracheostomy, and can result from direct injury to the pleura or positive pressure ventilation through a dislocation of the tracheostomy tube. We report an uncommon case of a tracheostomy-induced bilateral tension pneumothorax with a review of the literature.

The finding of a tracheal penetrating injury that's caused by a foreign body is rare in adulthood. A 42-year-old man had experienced penetrating trauma due to a glass fragment 10 years ago. He presented with blood tinged sputum and dyspnea on exertion, and this had developed 1 year previously. Chest CT scan and bronchoscopy revealed a foreign body crossing the tracheal lumen and the object arose from outside of the trachea; this was all associated with airway edema. We removed the foreign body, which was a 5cm length of glass fragment, and we repaired the tracheal defect using a simple primary suture. The postoperative course of the patient was uneventful and he is now being followed up at the outpatient department; he has had no additional symptoms.

Tracheal stenosis in children are often the result of prolonged intubation and its treatment depends on the severity and extent of the involved segment. Repeated surgical endoscopic procedures may be indicated in those with mild stenoses mainly consisting of granulation tissues, However, surgical reconstruction of the airway should be performed in patients with severe, extensive stenoses composed of mature scar tissue. The senior author has successfully managed such patients with cartilage graft augmentation and tracheal resection anastomosis. This is a presentation of 9 pediatric patients with tracheal stenosis who have been successfully treated by resection anastomosis. The details of the cases and indications for this type of surgery are discussed.

Purpose : Ventriculoperitoneal (VP) shunt insertion is an important treatment modality in children with hydrocephalus. VP shunt infection is a major complication and an important factor that determines the surgery outcome. This 15-year study was performed to evaluate the epidemiology of VP shunt infections in pediatric patients treated at our center. Methods : A retrospective review of medical records was performed in patients 18 years old or younger who underwent VP shunt insertion surgery from April 1995 to June 2010. Results : Three hundred twenty-seven VP shunt surgeries were performed in a total of 190 pediatric patients (83 females, 107 males). The median age of the patients was 2.4 years (range, 0.02-17.9 years). Having a malignant brain tumor was the most frequent cause for VP shunt insertion. The shunt infection rate was 6.7% (22/327) per 100 operations and 9.5% (18/190) per 100 patients, and the incidence rate was 0.45 infection cases per 100 shunt operations-year. The most common pathogen was coagulase-negative staphylococcus (n=7) followed by methicillin resistant Staphylococcus aureus (n=1). Ten cases were treated with vancomycin and beta-lactam antibiotic (cephalosporin or carbapenem) combination therapy and 7 cases were treated with vancomycin monotherapy. The median duration of antibiotic treatment was 26 days (range, 7 to 58 days). Surgical intervention was performed in 18 cases (18/22, 81.8%). Conclusion : Epidemiologic information regarding VP shunt infections in pediatric patients is valuable that will help guide proper antibiotic management. Additional studies on the risk factors for developing VP shunt infections are also warranted.

Hemophilia B is hereditary disorder of blood coagulation known as a deficiency of P.T.C. or Christmas factor. Anyway it's indistinguishable clinically with hemophia A and C. Here's one of most interesting problems gave us because we could only find it out as a hemophilia B. when we stood a situation to be met continuous bleeding from the operative wound of tonsillectomy and Adenoidectomy. Wintrobe proposed that easy bruising, difficulty in stopping the bleeding from razor cuts, and prolonged bleeding after tonsillectomy or tooth extraction usually are the major manifestations. For a long time little attention was paid to reports of a milder form of the diseases. In such cases coagulation time, and even prothrombin consumption were normal and the symptoms were correspondinly mild, small wounds as a rule giving little trouble and hemoarthrosis being uncommon. In our cases, there's no specific contributory history except nasal bleeding intermittently and also no specific contributory laboratory data before the operation. After the T. & A., there's continuous bleeding from nasopharynx and the coagulas on the both tonsilar fossas being grown day by day. Therefore we suspected some abnormality of coagulation mechanism and then we could get conclusion of hemophilia B. after various laboratory tests including T.G.T., As I know, this case, hemophilia B. is 3rd one as a report in Korea. We have no data of hemophilia family at present time, so that I propose that we have to make system of hemophilia family in Korea. In a next, we have to make routinely complete laboratory test, ego routine C.B.C., bleeding time, coagulation time, prothrombine time, partial thromboplastine time, before operation of T.& A. If we can solve these problems we can get the T. & A. without any problems of bleeding according to get the operation of T. & A.

Background: Postoperative morbidity and mortality in destroyed lung are relatively high. We tried to identify the prognostic factors affecting postoperative morbidity and mortality in destroyed lung through a retrospective study. Material and method: The retrospective study was undertaken in 112 patients who had undergone pneumonectomy or pleuropneumonectomy for destroyed lung at Severance Hospital from 1970 to 2000. We analyzed the correlation between postoperative morbidity and mortality and etiology, duration of disease, preoperative FEV1, presence or absence of peroperative empyema, operation timing, the side of operation, duration of operation, and operation type. Result: There were 55 men and 57 women, aged 20 to 81 years (mean 44 years). Etiologic diseases were tuberculosis in 86 patients(76.8%) including tuberculos empyema in 20 and tuberculous bronchiectasis in 4, pyogenic empyema in 12(10,7%), bronchiectasis in 12(10.7%), and lung abscess in 2(1.8%). Postoperative morbidity were 25%(n=28) and postoperative mortality was 6%(n=7). The presence of preoperative empyema(p=0.016), pleuropneumonectomy(p=0.037) and preoperative FEV1 of less than 1.75 L(P=0.048) significantly increased the postoperative morbidity, If operation time was less than 300min, postoperative morbidity(p=0.002) and mortality(p=0.03) were significantly low. Conclusion: Postoperative morbidity and mortality in destroyed lung were acceptable. Postoperative morbidity and mortality were significantly low when operation time was less than 300 min. Preoperative existence of empyema, pleuropneumonectomy and preoperative FEV1 of less than 1.75 L significantly increased postoperative morbidity.

Purpose: Based on previous research findings, it is well-known that the timing of surgery is generally considered the most important prognostic factor for a Kasai portoenterostomy, the primary treatment for biliary atresia. This research aimed to identify the optimal timing of a Kasai portoenterostomy and to verify if the proposed optimal timing corresponds to previous studies. All patients were classified by the timing of surgery, and pre- and post-operative fibrotic changes of the liver were measured with the elasticity value from fibroscans. Methods: The stiffness scores of the pre- and post-operative fibroscans in 34 patients who were treated by Kasai portoenterostomy from October 2007 to September 2010 in Severance children's hospital were reviewed. Results: The earlier the patients were treated by Kasai portoenterostomy, the lower the fibroscan scores. When the patients were treated prior to the 8th week, the post-operative scores of the fibroscans were significantly better than those patients who were treated after the 8th week, and some even recovered partially. Moreover, when operated before the 8th week, the differences between each pre- and postoperative fibroscan score also showed statistical relevance (p=0.0002). Conclusion: The earlier the patient was treated by Kasai portoenterostomy, the less liver fibrosis that developed, the lower the level of post-operative fibrosis, and the less the degree of fibrotic progress before and after the operation. Thus, this research proposal reconfirms once more that the 8th week is the optimal timing for a Kasai portoenterostomy.

Choanal atresia, described first by Johann Roedere (1755) is an obstruction between the nasal cavity and nasopharyngeal vault, and the diagnosis and treatment were developed because of severity of the disease. Embryologically, incomplete development of olfactory pit, or failure of nasobuccal membrane to rupture, or persistent remaining of buccopharyngeal membrane, etc, all forms the congenital choanal atresia. And the acquired type was the result from syphilis or diphtheria with a resultant stenosing cicatrix and after the inexpert surgery and the trauma. Multiple abnormalities may be present particularly affecting the head, the heart and the alimentary system in the congenital type. The operative technique employed would depend upon the type of obstruction(whether membranous or bony), the age of the patient, and the presence or absence of any associated pathologic condition. Since Emmert (1853) first tried blind puncture of the atretic plate with the trocar, other surgical techniques have been introduced over the years for the correction of choanal atresia, which were the transnasal, transpalatal, transantral and the transseptal approach. Among them, transpalatal approach was proved to be a popular technique, that it provides a direct route, thus permitting an exact reconstruction and low restenosis rate. Recently, we have experienced two cases of choanal atresia and treated successfully with transpalatal approach, so authors report these cases with a review of the literature.
