Background: Hydatidosis is a major health problem around the world, especially in the Mediterranean region. Cysts can break open or develop secondary bacterial infections, altering the clinical presentation. Methods: Patients who underwent hydatid cyst surgery at Al-Mouassat University Hospital in Damascus, Syria between January 2006 and December 2017 were evaluated. Cases involving isolated hepatic cysts were excluded. The patients were divided into those with perforated hydatid cysts (group 1) and those with intact hydatid cysts (group 2). Results: This study included 224 cases: 113 in group 1 (50.4%) and 111 in group 2 (49.6%). The median chest tube duration, hospitalization time, and postoperative complication rate were higher in group 1 than in group 2 (p=0.003, p=0.002, and p=0.006, respectively). In both groups, the most common symptom was cough (present in 178 patients in total [79.5%]), while chest pain (121 patients [54%]) and dyspnea (113 patients [50.4%]) were also common. Cough, hemoptysis, fever, and expectoration of cystic contents were significantly more frequent in group 1 than in group 2 (p<0.001). Conclusion: The early discovery and treatment of intact pulmonary hydatid cysts reduced the hospitalization time, chest tube duration, and postoperative complication rate. Relative to intact cysts, perforated cysts are more complex and are associated with more expensive and time-consuming surgical treatment.

Tube thoracostomy is known to cause complications such as bleeding or infection, but the incidence of chylothorax secondary to tube thoracostomy is under-reported, and therefore, we report this case. A patient was diagnosed as systemic lupus erythematosus with pleural and pericardial involvement. During repeated therapeutic thoracentesis, which were performed because of poor response to steroids and cylophosphamide, hemothorax developed and we therefore inserted a chest tube. The pleural effusion changed from red to milky color in several hours and we diagnosed the pleural effusion as chylothorax. Total parenteral nutrition based on medium-chain triglycerides was supplied to this patient and chylothorax was improved after 4 days.

The sternal turnover has a limited use in an asymmetrical funnel chest. However we tried `One-half sternal turnover` as a new operative approach for an asymmetrical funnel chest. Through the bilateral submammary skin incision, median sternotomy was made from xiphoid process to midsternum and extended horizontally. The segment of ribs were cut at the angle of depression. The en-bloc resected chest wall segment contained one-half sternum as well as a part of ribs and left half of rectus muscle. After turning over the en-bloc segment, reapproximation with wiring was done. Sternotomy wound was closed in layer after placing of substernal drainage tube. Postoperatively, the chest wall was stable and the recovery course was uneventful except left-sided minimal pneumothorax which was cured spontaneaously. The patient was discharged on postoperative 14th day.

Background: The aim of this study was to evaluate the feasibility of single-port video-assisted thoracic surgery (VATS) in the treatment of secondary spontaneous pneumothorax (SSP). Methods: Twenty-four patients who were scheduled to undergo single-port VATS for SSP were studied. The medical records of the patients were retrospectively reviewed. The mean follow-up duration was $26.1{\pm}19.8$ months. In order to evaluate the feasibility of single-port VATS for SSP, the postoperative results of single-port VATS (n=15) in patients with emphysema were compared with those of emphysematous patients who underwent three-port VATS (n=15) during the study period. Results: Single-port VATS was feasible in 19 of 24 patients (79.2%), while an additional port was needed in five patients. In the single-port VATS patients, the median operation time, duration of chest tube drainage, and hospital stay were 84.0 minutes, one day, and two days, respectively. Postoperative complications included prolonged chest tube drainage for more than five days (n=1), wound infection (n=1), and vocal fold palsy (n=1). No recurrence of pneumothorax was observed during the follow-up period. The median operation time, duration of chest tube drainage, and hospital stay of the emphysematous patients who underwent single-port VATS were shorter than those who underwent three-port VATS group (p<0.05 for all parameters). Conclusion: Single-port VATS proved to be a feasible procedure in the treatment of patients with secondary spontaneous pneumothorax.

배경: 원발성 자연기흉의 흉관삽입술의 적응증에 대해서는 잘 알려져 있지만, 어떤 크기의 흉관을 삽입할 것인가에 대해서는 특별한 지침이 없는 것으로 생각된다. 한편 최근에는 여러 가지 수술 수기에 대한 보다 최소한의 침습적인 치료방법들이 다양하게 소개되고 연구되는 경향이 있다. 본 교실에서는 이러한 추세에 따라 원발성 자연기흉의 흉관삽입슬에 있어서 기존의 24 Fr. 흉관을 12 Fr. 흉관으로 대신해 새로운 치료 지침에 따른 효용성을 확인하고자 한다. 대상 및 방법: 본원에서 원발성 자연기흉으로 진단 받고 흉관삽입술을 시행한 30세 이하의 환자를 대상으로, 2003년 1월부터 2003년 5월까지 24 Fr.흥관삽입술을 시행받은 환자 19예는 A군, 2003년 11월부터 2004년 4월까지 12 Fr.흉관삽입술을 시행받은 환자 20예는 B군으로 각각 분류하여 흉관삽입 시술시간, 흉관 거치기간, 재원일수, 합병증, 수술여부, 재발여부를 후향적인 방법으로 비교 조사하였다. 결과: 두 군 간의 남녀 비는 A군은 16 : 3, B군은 18 : 2였고, 나이는 A군은 21.7$\pm$4.0세, B군은 20.0$\pm$3.7세 였다. 흉관삽입 시술시간은 A군은 21.6$\pm$2.9분, B군은 10.8$\pm$1.9분으로 유의한 차이를 보였다(p<0.05). 흉관 거치기간은 A군은 3.8$\pm$1.7일, B군은 4.3$\pm$2.2일이었으며, 재원일수는 A군은 5.6$\pm$9일, B군은 5.2$\pm$1.5일이었다. 흉관 삽입술에 따른 합병증은 두 군에서 모두 없었으며, 기흉의 재발과 지속적인 공기 누출로 수술을 시행 받은 환자는 A군은 6예(35%), B군은 5예(25%)였다. 결과적으로 흉관삽입 시술 시간을 제외하고는 통계학적으로 유의한 차이가 없었다. 결론: 원발성 자연기흉의 흉관삽입술시 12 Fr. 흉관으로도 24 Fr. 흉관과 비교하여 효용성에 차이가 없다는 점과, 보다 시술이 쉽고 용이하여 시술 시간을 단축할 수 있는 장점이 있다고 생각된다.

Misinterpreting radiographic findings can lead to unnecessary interventions and potential patient harm. The urgency required when responding to the compromised health of trauma patients can increase the likelihood of misinterpreting chest x-rays in critical situations. We present the case report of a trauma patient whose skin fold artifacts were mistaken for pneumothorax on a follow-up chest x-ray, resulting in unnecessary chest tube insertion. We hope to help others differentiate between skin folds and pneumothorax on the chest x-rays of trauma patients by considering factors such as location, shape, sharpness, and vascular markings.

배경: 원발성 자연기흉에 대한 초 치료의 목적은 흉막강 내의 공기 제거와 폐장의 재팽창 유도이며, 이를 위해 통상적으로 20 Fr이상 크기의 흉관을 흉막강에 삽입한다. 그러나 원발성 자연기흉의 병태 생리를 고려할 때보다 작은 크기의 흉관으로도 소기의 목적을 달성할 수 있다는 생각에서, 7 Fr 크기의 도관을 흉관으로 사용하여 그 효용성과 보완점을 제시하고자 하였다. 대상 및 방법: 2003년 5월부터 2005년 4월까지 원발성 자연기흉으로 입원 치료를 한 환자 중 초 치료로 흉강삽관술을 시행한 111명의 환자를 대상으로 의무기록을 토대로 후향적으로 조사하여, 7 Fr 흉관을 사용한 환자들과 24 Fr 흉관을 사용한 환자들의 흉관 거치기간, 진통제의 사용여부, 폐의 재팽창 정도, 합병증 등에 대해 분석하였다. 결과: 흉관의 평균 거치기간은 7 Fr군이 $2.4{\pm}1.1$일, 24 Fr군이 $2.3{\pm}1.3$일로 차이가 없었다. 주사 진통제의 사용은 7 Fr군에서는 없었으나 24 Fr군에서는 모든 환자들이 사용하였다. 7 Fr 흉관만을 사용하여 치료한 환자들의 77%에서 폐장의 완전 재팽창을 얻을 수 있었다. 7 Fr 흉관의 문제점은 도관의 꺾임이며, 5.6%에서 발생하였다. 결론: 7 Fr 흉관을 이용한 원발성 자연기흉의 초 치료는 기존의 24 Fr 흉관과 비교하여 공기제거, 폐의 재팽창, 통증경감, 미용적 측면에서 모두 만족할 만 하였으나, 꺾임을 방지할 수 있게 도관의 개량이 필요하다고 생각한다.

Purpose : Skip the repetitive HRCT axial scan in order to reduce the exposure of patients during chest HRCT scan, Helical Scan Data into a reconstructed image, and exposure of the patient change and visually evaluate the usefulness of the HRCT images. Materials and method : Patients were enrolled in the survey are 50 people who underwent chest CT scans of patients who presented to the hospital from January 2015 to March 2015. 50 people surveyed 22 people men and 28 people women people showed an average distribution of 30 to 80 years age was 48 years. 50 patients to Somatom Sensation 64 ch (Siemens) model with 120 kVp tube voltage to a reference mAs tube current to mAs (Care dose, Siemens) as a whole, including the lungs and the chest CT scan was performed. Scan upon each patient CARE dose 4D (Automatic exposure control, Siemens Medical Solution Erlangen, Germany) was to maintain the proper radiation dose scan every cross-section through a device that automatically adjusts the tube current of. CT scan is the rotation time of the Tube slice collimation, slice width 0.6 mm, pitch factor was made under the terms of 1.4. CT scan obtained after the raw data (raw data) to the upper surface of the axial images and coronal images for each slice thickness 1 mm, 5 mm intervals in the high spatial frequency calculation method (hight spatial resolution algorithm, B60 sharp) was the use of the lung window center -500 HU, windows were reconstructed into images in the interval -1000 HU to see. Result : 1. Measure the total value of DLP 50 patients who proceed to chest CT group A (Helical Scan after scan performed with HRCT) and group B (Helical Scan after the HR image reconstruction to the original data) compared with the group divided, analysis As a result of the age, but show little difference for each age group it had a decreased average dose of about 9%. 2. A Radiation read the results of the two Radiologist and a doctor upper lobe and middle lobe of the lung takes effect the visual evaluation is not a big difference between the two images both, depending on the age of the patient, especially if the blood vessels of the lower lobe (A: 3.4, B: 4.6) and bronchi(A: 3.8, B4.7) image shake caused by breathing in anxiety (blurring lead) to the original data (raw data) showed that the reconstructed image is been more useful in diagnostic terms. Conclusion : Scan was confirmed a continuous, rapid motion video to get Helical scan is much lower lobe lung reduction in visual blurring, Helical scan data to not repeat the examination by obtaining HRCT images reorganization reduced the exposure of the patient.

본 연구는 흉부 방사선검사 시 AEC의 잘못된 사용으로 환자에게 가해지는 피폭선량 및 영상판독의 문제점을 개선하고자 연구를 진행하였다. 검사조건으로 AEC를 이용한 경우와 AEC를 사용하지 않은 경우로 구분하여 영상을 획득 하였으며 0.6 mAs를 고정시키고 110, 100, 90, 80 kVp의 조건으로 촬영하였다. 연구 결과 without AEC 110 kVp가 with AEC보다 선량은 1.17% 감소하였고 100 kVp에서는 17.2% 감소, 90 kVp에서는 30.19% 감소, 80 kVp에서는 46.45% 감소하였다. 폐와 기관, 심장에서 SNR의 평균값의 차이는 with AEC와 without AEC 110 kVp에서 관전압 변화에 따른 통계적인 수치에서는 유의한 차이가 있었으나 실제영상에서 화질의 차이는 미비하였다. 동일한 관전압에서 AEC를 적용하지 않은 경우 특히 without AEC 100kVp에서는 with AEC와 유사한 화질을 유지하면서 선량을 17.2% 감소시킬 수 있었다. 그러므로 흉부 방사선 검사 시 AEC 조건에 의존하기보다 적절한 관전압 선택으로 선량을 낮추면서 검사하는데 조건을 고려해 보아야 할 것으로 사료된다.
