During the period of seven years from Jan. 1976 to Jan. 1983, one hundred cases of pulmonary tuberculous residual lesions were resected at the Department of Thoracic Surgery, Paik Hospital in Seoul, Korea. During the period of this study, 1764 patients were admitted with the diagnosis of pulmonary and/or pleural tuberculosis in the medical and surgical department as a primary or associated conditions. Among these 1764 patients, one hundred selective cases were operated. The results were as follows; l. Extents of the disease by the predominant clinical pictures were: totally destroyed lung; 18, destroyed lobe; 6, cavitary lesion with or without positive sputum; 35, bronchiectasis; 7, bronchostenosis with atelectasis; 2, empyema with or without BPF; 20, pleural thickening; 4, tuberculoma; 3, bullous cyst with tuberculosis; 5 cases, or per cent [Table 1]. 2. Male and female ratio was 1.2:1 or 55 and 45 per cent. Age distribution ranged 15 and 55 with average of 33 years [Table 2]. 3. Type of procedures were: pleuropneumonectomy; 15, pneumonectomy; 25, lobectomy; 37, bilobectomy; 6, lobectomy plus segmentectomy; 3, pleurectomy; 14 cases, or percent, Site of resections were: right; 58 and left; 42 cases, or per cent [Table 3]. 4. Incidence of complications were 10 per cent and the mortality was 4 per cent. The causes of morbidity were analyzed. The main causes of death were pulmonary insufficiency; 2, cardiac arrhythmia; 1, and hepatic insufficiency; 1 case or per cent [Table 4]. 5. Pathologic examinations of the resected pulmonary and pleuropulmonary lesions were observed by gross specimen, correlating with the pre-operative indications of the disease [Fig. 1, 2, 3, 4, 5, 6].>br> 6. Anti-tuberculous chemotherapy was done for 6 to 18 months, post-operatively, in 80 patients. Of these 49 cases were need medication for 12 months [Table 5]. Except the four operative mortality and a case of post-operative recurrent buberculosis under medication, all the other 95 cases are well in activity and free from the disease at the moment.

Since the advent of potent chemotherapy, the incidence and severity of bronchiectasis have been on the decrease. Up to date, however, the medical treatment of bronchiectasis has not given us much satisfaction. Our purpose here is to show our experiences with pulmonary resections of bronchiectasis to clarify its surgical results and define its surgical indications. Sixty-five patients with bronchiectasis, treated surgically from January 1973 to December, 1982 at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital, were given clinical assessment. Of the 65 patients involved in the series, 49 were male and 16, female. The patients ranged from 8 to 51 in ages, with 59 cases [91%] between 10 and 39 years old. The prominent clinical features were as follows: cough [88%], sputum production [78%], recurrent upper respiratory infection [51%], and frequent hemoptysis [32%]. The past history of the patients included measles 29%, whooping cough 14%, pulmonary tuberculosis 12%, and pneumonia or bronchitis 12%. The cylindrical type of the bronchiectasis was found to be most common, accounting for 43% of the cases. The operations were performed on the left lung in 52 cases and the right lung in 13 cases. The most common operative procedure was the left lower lobectomy and lingular segmentectomy, which showed 34%. The second most frequent procedure was the simple left lower lobectomy which was 22%. Incomplete resections of the multisegmental bronchiectasis were carried out in 12 cases, of which 7 cases were satisfactory Four patients underwent bilateral pulmonary resections for the severe multisegmental bilateral bronchiectases, during the first and second operations. Improvement in pulmonary symptoms was generally obtained in all four cases. The follow-up ranged from 1 week to 7 tears, with an average of 18.8 months. The overall results revealed that 87% of these and excellent or good conditions, but 13% had persistent symptoms. There was one operative death, which is a 1.5% mortality.

Objective : The treatment of malignant posttraumatic brain swelling remains a frustrating endeavor for neurosurgeon. Mortality and morbidity rates remain high depite advances in medical treatment of increased intracranial pressure. If conventional therapy fails in patients suffering from intracranial hypertension, there is only small number of second-tier option left including decompressive craniectomy. The role of decompressive craniectomy in posttraumatic brain swelling remains controversial. We assessed the efficacy and indications of decompressive craniectomy. Methods : The authors performed decompressive bifrontotemporal craniectomy in 22 patients with malignant posttraumatic brain swelling. Epidural pressure monotoring was performed in all patients. The clnical data and surgical outcomes were reviewed retrospectively. Result : The favorable outcome(GOS score 4-5) was 59%(13 of 22 patients), whereas the mortality rate was 32% (7 of 22 patients). Two patients(9%) remained in severely disabled state. Increased rate of favorable outcome was seen in the patients who had 8 or more of GCS score at admission and exhibited B wave in ICP monitoring and who showed steady state or slow deterioration in clinical course. Conclusion : If conservative therapy fails, decompressive bifrontotemporal craniectomy should be considered in the management of malignant posttraumatic brain swelling before irreversible ischemic brain damage occur.

Objective : Twist-drill craniostomy (TDC) with closed-system drainage and burr-hole drainage (BHD) with a closed system are effective treatment options for chronic subdural hematoma (CSDH). The aim of this study was to analyze clinical data and surgical results from symptomatic CSDH patients who underwent TDC with closed-system drainage at the pre-coronal point (PCP). Methods : We analyzed data for 134 symptomatic CSDH patients who underwent TDC at the PCP with closed-system drainage. We defined the PCP for TDC to be 1 cm anterior to the coronal suture at the level of superior temporal line. TDC at the PCP with closed-system drainage was selected in patients with CSDH that extended beyond the coronal suture, confirmed by preoperative CT scans. Medical records, radiological findings, and clinical performance were reviewed retrospectively. Results : Of the 134 CSDH patients, 114 (85.1%) showed improved clinical performance and imaging findings after surgery. Catheter failures were seen in two cases (1.4%); the catheters were inserted in the epidural space. Recurrent cases were seen in eight patients (5.6%), and they were improved with a second BHD with a closed-system operation. Conclusion : TDC at the PCP with closed-system drainage is safe and effective for patients with symptomatic CSDH whose hematomas extend beyond the coronal suture.

Recently, the incidence of perinatally detected asymptomatic adrenal gland masses has increased because of widespread use of radiological diagnostic tools. However, optimal treatment of these masses has not been determined. The aim of this study is to elucidate the treatment guideline of perinatally diagnosed adrenal gland masses. The authors retrospectively reviewed the medical records of the 11 patients with asymptomatic adrenal gland mass, detected perinatally, between 1999 and 2004. Six cases were detected by prenatal ultrasound and 5 cases were incidentally detected by postnatal ultrasound. Six patients (surgery group) underwent mass excision. The pathologic diagnoses were neuroblastoma (n=4), adrenocortical adenoma (n=1) and adrenal pseudocyst (n=1). The indications for operation were suspicion of neuroblastoma (n=5) or absence of size decrease during observation (n=1). Three of the 5 suspicious cases of neuroblastoma and one case under observation were proven to be neuroblastoma. There was no surgical complication in the urgery group. All neuroblastoma patients have been well during the follow up period ($24.4{\pm}14.4$ month) without evidence of recurrence. Five cases (observation group) were closely observed because of the benign possibility or size decrease in follow up ultrasound. During the observation period ($39{\pm}21$ week), 4 cases showed complete spontaneous resolution and 1 case showed markedly decreased size of the mass but could not be followed up completely. Surgical resection of the perinatally diagnosed asymptomatic adrenal gland mass is a safe treatment method especially in case of suspicion of neuroblastoma, but closed observation can be applied.

Purpose: Noninvasive prenatal test (NIPT) by massively parallel sequencing (MPS) of cell-free fetal DNA in maternal plasma marks a significant advancement in prenatal screening, minimizing the need for invasive testing of fetal chromosomal aneuploidies. Here, we report the initial clinical performance of NIPT in Korean pregnant women. Materials and Methods: MPS-based NIPT was performed on 910 cases; 5 mL blood samples were collected and sequenced in the Shenzhen BGI Genomic Laboratory to identify aneuploidies. The risk of fetal aneuploidy was determined by L-score and t-score, and classified as high or low. The NIPT results were validated by karyotyping for the high-risk cases and neonatal follow-up for low-risk cases. Results: NIPT was mainly requested for two clinical indications: abnormal biochemical serum-screening result (54.3%) and advanced maternal age (31.4%). Among 494 cases with abnormal biochemical serum-screening results, NIPT detected only 9 (1.8%) high-risk cases. Sixteen cases (1.8%) of 910 had a high risk for aneuploidy: 8 for trisomy 21, 2 for trisomy 18, 1 for trisomy 13, and 5 for sex chromosome abnormalities. Amniocentesis was performed for 7 of these cases (43.8%). In the karyotyping and neonatal data, no false positive or negative results were observed in our study. Conclusion: MPS-based NIPT detects fetal chromosomal aneuploidies with high accuracy. Introduction of NIPT as into clinical settings could prevent about 98% of unnecessary invasive diagnostic procedures.

Thyroid nodules are less common in children than in adults and their management is still controversial. The clinical presentations, operations, complications, histopathologic findings, and postoperative progressions of 34 pediatric patients that underwent thyroidectomy for palpable thyroid nodule at the Department of Surgery, Seoul National University Children Hospital between 1986 and 2003 were studied retrospectively by reviewing medical records and telephone interviews. The mean age of the patients was 11.8 years old. There were 23 females (67.6 %) and 11 males (32.4 %). Surgical indications were clinical need of histological confirmation (n=15), unresponsiveness to thyroxin replacement therapy (n=10), suggestion of the carcinoma on fine needle aspiration cytology (n=5), cosmetic purpose-a huge benign nodule (n=2), completion thyroidectomy for medullary thyroid carcinoma (n=1), and prophylactic thyroidectomy in a MENIIpatient (n=1). Unilateral Lobectomy was performed in 20 patients (57.1 %), subtotal thyroidectomy in 8 (22.9 %), total thyroidectomy in 5 (14.7 %), and completion thyroidectomy in 1 (2.9 %). Lymph node dissection was performed in 9 cases. Benign tumor was found in 23 patients (67.6 %), adenomatous goiter (n=18) and follicular adenoma (n=5). Malignant tumor was found in 11 children (32.4 %), 9 papillary carcinomas (26.5 %), and 2 medullary carcinomas (5.9 %). Of the 9 papillary carcinomas, 7 cases (77.8 %) had lymph node metastasis. No lymph node metastasis was found in 2 medullary carcinomas. Complications developed in 5 cases - transient hypocalcaemia (n=2), and temporary hoarseness (n=3). There was no mortality. Median follow-up period was 7.4 years (0.5-18 years). One patient showed recurrence in cervical lymph nodes 10 years after surgery and modified radical neck dissection was performed. Because of the high incidence of malignancy and advanced stage at initial presentation, more meticulous diagnostic work up is necessary for children with thyroid nodule, and more radical surgical treatment should be performed when malignant nodule is suggested.
