A 53-year-old woman had right aortic arch, Kommerell’s diverticulum and aberrant left subclavian artery (LSA) without any compressive symptoms. Hybrid operation was performed. This consisted of LSA bypass using a 6 mm ringed Gore-Tex graft between the left common carotid artery and aberrant LSA via a left supraclavicular incision, and stent graft insertion into the aortic arch via the right femoral artery. Postoperative computed tomography as well as intraoperative angiography demonstrated successful occlusion of Kommerell’s diverticulum and bypass of the aberrant LSA. There were no complications related to the operation or the intervention.

Background: After general anesthesia, decrease of functional residual capacity and lung compliance, ventilation/perfusion imbalance, and transpulmonary shunting can provoke hypoxemia during postoperative periods. Diaphragmatic dysfunction may be the main cause of these physiological abnormalities. Thus, we evaluated the change of pulmonary function after general anesthesia according to the operative sites, which could suggest clinical course and critical period of respiratory care of postoperative patients. Method: Preoperative portable spirometric evaluation and arterial blood gas analysis were performed at sitting or most-sitting position just previous day of surgery. Pulmonary function tests were also as same condition from postoperative day 1 to day 5. Results: 1) For thoracic surgery, FEV1 and FVC were not recovered at day 5, but FEV1/FVC was not decreased. $PaCO_2$ was slightly elevated at postoperative one day. 2) After upper abdominal surgery, postoperative day 5 did not show the recovery of FEV1 and FVC, but mild hypoxemia was developed at postoperative day 1. 3) Pulmonary function was recovered as preoperative value at postoperative day 5 in lower abdominal operation, but mild hypoxemia was also noted at postoperative day 1. 4) Surgery of peripheral areas did not show significant pulmonary function change and hypoxemia and hypercapnia from postoperative day 1. Conclusion: Surgery involving diaphragm provoke significant postoperative pulmonary function change after day 5. For the operation of peripheral sites adequate respiratory care during operation and postoperative period within 24 hours could prevent patients from respiratory complication.

Purpose : Craniopharyngiomas are often accompanied by severe endocrine disorders. Although there is universal growth hormone deficiency(GHD), the resulting growth pattern is very heterogeneous. We report the growth and endocrine outcome of 44 children with craniopharyngioma, with emphasis on initial symptoms, growth before and during growth hormone(GH) treatment and spontaneous growth in spite of GHD. Methods : We performed a retrospective study of 44 children treated at our centre between 1984 and 2002. Results : About 30% of patients had symptoms suggesting endocrine disorder at diagnosis. After surgery, multiple endocrinopathies were almost universal. Before GH therapy, height velocity was $8.00{\pm}2.71cm/yr$ in the normal growth group(n=11) and $1.79{\pm}1.10cm/yr$ in the subnormal growth group(n=7) during the first year and during the second year, $6.76{\pm}2.49cm/yr$ and $2.29{\pm}1.33cm/yr$, respectively. There was no difference of body mass index(BMI) change between before and after surgery in the two groups. Height standard deviation score(SDS) was $-1.46{\pm}0.74$ in the normal growth group and $-0.43{\pm}0.97$ in the subnormal growth group. Before GH treatment height SDS was $-1.31{\pm}1.25$ and BMI was $20.46{\pm}3.60$. During GH treatment, height SDS increased to $-0.60{\pm}1.37$ in the first, and to $-0.41{\pm}1.54$ in the second year(P<0.05), but BMI did not change significantly. Conclusion : The endocrine morbidity could develop in most children with craniopharyngioma before and after the operation and should be managed properly. Although all treated patients benefit from GH therapy, further studies are necessary to find out the possible mechanism of growth regulation in normally growing children, despite GH deficient.

Background: Surgery for Stanford type A aortic dissection shows a high operative mortality rate and frequent postoperative brain injury. This study was designed to find out the risk factors leading to operative mortality and brain injury after surgical repair in patients with type A aortic dissection. Material and Method: One hundred and eleven patients with type A aortic dissection who underwent surgical repair between February, 1995 and January 2005 were reviewed retrospectively. There were 99 acute dissections and 12 chronic dissections. Univariate and multivariate analysis were performed to identify risk factors of operative mortality and brain injury. Resuit: Hospital mortality occurred in 6 patients (5.4%). Permanent neurologic deficit occurred in 8 patients (7.2%) and transient neurologic deficit in 4 (3.6%). Overall 1, 5, 7 year survival rate was 94.4, 86.3, and 81.5%, respectively. Univariate analysis revealed 4 risk factors to be statistically significant as predictors of mortality: previous chronic type III dissection, emergency operation, intimal tear in aortic arch, and deep hypothemic circulatory arrest (DHCA) for more than 45 minutes. Multivariate analysis revealed previous chronic type III aortic dissection (odds ratio (OR) 52.2), and DHCA for more than 45 minutes (OR 12.0) as risk factors of operative mortality. Pathological obesity (OR 12.9) and total arch replacement (OR 8.5) were statistically significant risk factors of brain injury in multivariate analysis. Conclusion: The result of surgical repair for Stanford type A aortic dissection was good when we took into account the mortality rate, the incidence of neurologic injury, and the long-term survival rate. Surgery of type A aortic dissection in patients with a history of chronic type III dissection may increase the risk of operative mortality. Special care should be taken and efforts to reduce the hypothermic circulatory arrest time should alway: be kept in mind. Surgeons who are planning to operate on patients with pathological obesity, or total arch replacement should be seriously consider for there is a higher risk of brain injury.

The study was done to analyze the effects of aroma inhalation method on preoperative anxiety of upper and lower surgical patients. The research design was a nonequivalent control group non-synchronized design. The subjects were a total 60 patients of each group 30 patients that were operated on under general anesthesia for upper and lower limbs surgery. The tool of the Amsterdam preoperative anxiety information scale(APAIS), systolic and diastolic blood pressure, and pulse rate levels was measured the day before surgery. The data were analyzed by the $x^2$ test Fisher's exact test, paird t-test, and the independent t-test using SPSS 20.0. Study result indicated that Lavender aroma therapy had the effect on reduction of anxiety before surgery and reduction of blood pressure, and pulse rate levels. Therefore, the study result could be used as a scientifical data that can be applied to the nursing interventions that use the aroma inhalation method and contributing to development of the holistic nursing care.

배경 및 목적: 최근 비디오 흉강경술은 최소 침습적인 수술 방법으로서 자연 기흉의 일반적 치료법으로 인정되고 있으나 비교적 높은 재발율과 비용-효용 관계에 대해서는 논란이 있다. 비디오 흉강경을 이용한 기포 절제술 후의 재발율은 평균 5-10%정도로 보고되고 있으며 이는 개흉술에 비해 상당히 높은 것이다. 또한 국내 의료 실정에서의 개흉술과 비디오 흉강경술의 비용효용에 대한 비교 통계는 없는 상황이다. 대상 및 방법: 1997년 1월부터 1999년 7월까지 일차성 자연기흉으로 성균관 의대 강북삼성병원 흉부외과에서 수술을 시행한 173예를 대상으로 후향적 조사하였다. 비디오 흉강경술로 시행한 104예와 개흉술로 시행한 69예를 양군으로 나누어 성별 및 연령, 발병부위, 수술의 적응증, 수술시간, 술 후 흉관 삽입기간 및 재원 일수, 술후 합병증, 재발율, 수술 경비 및 총치료경비 등을 비교하였다. 결과: 양군의 성별, 연령, 발병부위 등에는 차이가 없었다. 수술 시간은 흉강경군이 73.1$\pm$29.5분, 개흉군이 141$\pm$52분이었다.(p<0.05). 술 후 평균 흉관의 거치기간 및 재원일수는 흉강경군이 각각 3.93일 및 7.5일, 개흉군이 7.0일 및 13.4일이었다.(P<0.05, P<0.05). 술 후 재발한 경우가 비디오 흉강경군에서 6예(5.6%), 개흉군에서 1예(1.4%) 있었다(P<0.05). 본원에서 시행한 비디오 흉강경술과 개흉술의 비교에서 수술로 발생하는 비용은 비디오 흉강경군이 유의하게 높았으나 (1,202,192$\pm$178,992원, 1,005,669$\pm$311,531원; P<0.05) 총 치료비의 비교에서는 유의한 차이가 없었다.(1,946,110$\pm$487,440원, 1,793,912$\pm$308,079원; P=0.18). 결론: 비용 효용관계 및 재발율은 병원마다의 수술 수기 및 퇴원 정책등에 따라서 다소간의 차이가 있을 수 있으나 본원의 조사 결과에서는 비디오 흉강경술이 개흉술에 비해 비용-효과가 있다고 볼 수 없으며 재발율도 높았다.

Study Design: Retrospective study of prospectively-collected data. Objectives: To determine the factors associated with conversion from conservative to surgical treatment in single-level lumbar spinal stenosis patients. Summary of Literature Review: Various reports have presented clinical outcomes after the surgical and nonsurgical treatment of spinal stenosis. However, few reports have investigated factors predicting conversion to surgery during the course of conservative treatment. Materials and Methods: We analyzed 40 patients who visited our hospital from May 2010 to May 2015 and were traceable for at least 3 years after being advised to undergo surgery following 3 months of conservative treatment. Of these patients, 20 underwent surgery and 20 did not. We then investigated the factors associated with conversion to surgical treatment. Clinical assessments were conducted using a questionnaire, and the overall area of the spinal canal and the muscle area within the spinal canal were measured using magnetic resonance imaging. Results: The average area of the spinal canal was $81.40{\pm}53.61mm^2$ in the surgical group, compared to $127.75{\pm}82.55mm^2$ in the nonsurgical group (p=0.042). The muscle area in the spinal canal was $5.17{\pm}1.30cm^2$ in the surgical group, whereas it was $6.40{\pm}1.56cm^2$ in the nonsurgical group (p=0.010). The patients in the surgical group were more likely to have experienced repetitive strain and to have frequently visited health clubs (p=0.047, p=0.037, respectively). However, regular stretching was more common in the nonsurgical group (p=0.028). Conclusions: The factors associated with conversion to surgical treatment were a narrow spinal canal, a small muscle area within the spinal canal, visiting health clubs, repetitive sprain, and not stretching. A small muscle area within the spinal canal can be considered as a key factor related to surgical conversion.

Background: The incidence of cervical esophageal cancer is low compared with that of thoracic esophageal cancer, and the role of surgery for cervical esophageal cancer is limited compared with that of radiotherapy or chemotherapy. This study was carried out to determine the outcome of surgery for cervical esophageal cancer. Material and Method: We analyzed retrospectively medical records of 43 patients who had undergone curative surgical resection for cervical esophageal cancer from January 1989 to December 2002. Follow-up loss was absent and the last follow-up was carried out in February 28, 2004. Result: The mean age was 60 years old and the male to female ratio was 40:3. Histologic types were squamous cell carcinoma 42 patients and malignant melanoma 1 patient. The methods used for esophageal reconstruction were gastric pull-up 32 patients, free jejunal graft 7 patients and colon interposition 4 patients. Postoperative complications occurred in 31 patients (72%), and operative mortality occurred in 7 patients (16%). Pathologic stages were I 3, IIa 14, IIb 1, III 19, and IVa 6 patients. Tumor recurrence occurred in 16 patients (44%), and the 3 and 5-year survival rates were 29.3% and 20.9%. Conclusion: The reported surgical results for cervical esophageal cancer showed somewhat high operative mortality, postoperative complication rates and recurrence rates and a low long-term survival rate. It is suggested that multimodality treatment including surgery is needed for the treatment of cervical esophageal cancer because radiotherapy or chemotherapy without surgery could not relieve dysphagia or resolve the tumor completely.

Obstructive sleep apnea syndrome(OSAS) is a common disease in the field of otorhinolaryngology and is characterized by repeated upper airway occlusions occurring during sleep. OSAS can occur due to various etiologies of the nasal, oral, pharyngeal and laryngeal airway in adults. Nasal obstruction can be caused by septal deviation, nasal polyps, concha bullosa, choanal atresia, neoplasms, foreign body, postoperative/post-traumatic synechiae, various rhinitis and so on. There are various kinds of surgical treatment of OSAS including nasal surgery, LAUP, UPPP, surgery of tongue base, tracheostomy and so on, but the effect of nasal surgery on snoring and OSAS is controversial. The authors report the case of a patient who had experienced nasal obstruction, moderate snoring and OSAS and who improved after septoplasty and turbinoplasty.
