Mediastinal lymph node dissection is an important part of lung cancer surgery that provides accurate nodal staging and may improve survival outcomes. The minimally invasive approach, such as video-assisted thoracic surgery (VATS) lobectomy for patients with non-small cell lung cancer, has become a standard operation worldwide. VATS mediastinal lymph node dissection should be thorough and accurate to ensure the completeness of lung cancer surgery. Herein, the author describes techniques for VATS mediastinal lymph node dissection.

Objective : The authors analyzed the results of management outcomes for basilar bifurcation aneurysms treated with transcranial surgery and endovascular surgery. Methods : At the authors' institution between May 1989 and December 1998, 47 aneurysms with 45 patients were treated with transcranial surgery including surgical clipping/wrapping and endovascular surgery for basilar bifurcation aneurysms. The medical records and neuroimaging studies of the patients were reviewed retrospectively. Results : Of the 45 patients, 87 percent of the aneurysms were ruptured and 13% unruptured. Forty six percent of the patients had multiple aneurysms including basilar bifurcation aneurysm. Of the 39 patients with subarachnoid hemorrahge, 77% were in good neurological status(Hunt Hess grade I-III), 23% were in poor grade(H-H grade IV-V). Thirty two patients were treated with transcranial surgery and 15 patients were treated with endovascular surgery. Two patients who had treated with wrapping surgery later bled during follow-up period and treated with endovascular surgery. The management outcome of the transcranial surgery was : Glasgow outcome scale(GOS) I 66%, GOS II 12.5%, GOS III 6.3%, GOS IV 6.3% and GOS V(death) 9.4%. The major causes of morbidity related to transcranial surgery were perforator occlusion, vasospasm and retraction injury. The management outcome of the endovascular surgery was : GOS I 66.7%, GOS II 6.7%, and GOS V 26.7%. The major causes of mortality related to endovascular surgery were related to intraoperative aneurysmal bleeding. Conclusion : This report documents that more than 75% of patients undergoing treatment either transcranial or endovascular surgery can expect good clinical outcomes. Treatment modality in management of basilar bifurcation aneurysm must be carefully selected based on various considering factors.

Purpose: Surgery is the most common risk factor for pulmonary embolism (PE) in patients with a recent venous thromboembolism (VTE). This study reviewed clinical outcomes of preoperative inferior vena cava filter (IVCF) use in patients with acute VTE during abdominal-pelvic cancer or lower extremity orthopedic surgeries. Materials and Methods: We retrospectively analyzed 122 patients with a recent VTE who underwent IVCF replacement prior to abdominal-pelvic cancer or lower extremity orthopedic surgery conducted between January 2010 and December 2016. Demographics, clinical characteristics, postoperative IVCF status, risk factors for a captured thrombus, and clinical outcomes were collected for these subjects. Results: Among the 122 study patients who were diagnosed with acute VTE in the prior 3 months and underwent preoperative IVCF replacement, 70 patients (57.4%) received abdominal-pelvic cancer surgery and 52 (42.6%) underwent lower extremity orthopedic surgery. There were no perioperative complications associated with IVCF in the study population and no cases of symptomatic PE postoperatively. A captured thrombus in the filter was identified postoperatively in 16 patients (13.1%). Logistic regression analysis indicated that postoperative anticoagulation within 48 hours significantly reduced the risk of a captured thrombus (odds ratio [OR], 0.28; 95% confidence interval [CI], 0.08-0.94; P=0.032). Conclusion: A captured thrombus in preoperative IVCF was identified postoperatively in 16 patients (13.1%). Postoperative anticoagulation within 48 hours reduces the risk of captured thrombus in these cases.

Fibrous dysplasia is quite a rare disease usually involving maxilla and mandible. Because of its benign clinical course, conservative contouring surgery has been recommended for facial deformity. 3D rapid prototype (RP) model gives a lot of informations before operation such as depth of drilling, area of resection and important anatomic structure. The purpose of this study was to report maxilla-mandibular contouring surgery in fibrous dysplasia patients. A total of 14 consecutive patients were included for surgical and esthetic evaluation. Among 14 patients, RP model study was performed in two patients with severe facial deformity. The other patients underwent contouring surgery under conventional methods. Surgical evaluation was performed with computed tomography scan before and after operation. Surgical resection was successful and patients were satisfied with the surgical results.

Meckel's diverticulum is one of the common causes of gastrointestinal bleeding in the pediatric patient requiring laparotomy. Two children with Meckel's diverticulum have been successfully treated by laparoscopic excision. Both patients recovered without incident and were discharged at 3 and 5 days after surgery. The authors believe that laparoscopic diverticulectomy is a safe, effective. and minimal invasive treatment of Meckel's diverticulum in children.

Aorto-ventricular tunnel is a rare congenital malformation, and aorto-right ventricular tunnel (ARVT) is an even less common entity. Here, we report the case of a 3-month-old female who underwent successful surgical closure of ARVT. The origin of the right coronary artery was proximal to the ostium of the tunnel.

As a functionally complicated facility, it requires rational strategy to accommodate multi-functional needs to plan a hospital. Ambulatory surgery units located in large hospitals have problems such as longer waiting time and congestion for patients due to complicated planning and organization within limited area, which raise needs for independent ambulatory surgery centers to enable smoother medical treatment for patients. To design an independent ambulatory surgery center, understanding of zoning and layout of each unit needs is particularly required. This study focuses on research of efficient zoning/organization of day surgery unit and circulation arrangements of ambulatory surgery centers by analyzing various examples abroad, which will eventually help finding appropriate way of planning domestic ambulatory surgery centers. Specific area of research includes ambulatory surgery process, programmatic requirements, spatial organization of the facility, layout of surgery unit and circulation arrangements of ambulatory surgery centers.
