  • An occurrence of hemangioma in the mediastinum is a very rare, accounting for less than 0.5% of mediastinal tumors. Capillary hemangiomas and cavernous hemangiomas consists of over 90% of mediastinal hemangiomas. However, venous hemangioma has never been reported in South Korea and has also very rarely been reported worldwide. We found mediastinal solid mass, as an incidental finding during a follow-up chest CT scan of a 44-year-old female patient who had undergone colon cancer surgery. We performed a mediastinoscopic biopsy. We did a thoracotomy to remove this mass because hemorrhage and found a totally resected venous hemangioma.

  • Purpose: With the introduction of H. pylori eradication and proton pump inhibitor, the operative treatments for the acute or chronic complications of peptic ulcer, such as perforation, bleeding and stricture, have decreased. Also owing to the development of non-operative treatment such as interventional endoscopic treatment, the surgical approach to the acute complications, like perforation and bleeding, has diminished. The non-operative treatments for the stricture and obstruction of chronic peptic ulcer in part related to discontinuation of medication have not been satisfactory. We analyzed the clinical outcomes of the patients who underwent operative treatment for outlet obstruction with peptic ulcer. Materials of Methods: From January 1994 to December 2007, we reviewed 31 patients who had been operated on at the National Medical Center for peptic ulcer obstruction. We excluded the cases of adhesive obstructions that were caused by a former ulcer operation and also the cases of obstructions found during emergency operations for treating perforation and bleeding. We classified the surgical treatment group into the bypass operation group and the surgical resection group. We evaluated the effects of the operations by the Visick score. The recurrences were confirmed only by the endoscopic observation of peptic ulcer. Results: The number of patients in the bypass operation group was 6 (19.4%) and that of resection group was 25 (80.6%). The mean age was 57.5 (25~81) years. The number of male patients was 29 (93.5%) and the number of females was 2 (6.5%). The mean symptom duration was 29.6 months. There were 19 smokers (61.3%), 6 NSAID users (19.4%) and 7 H. pylori positive patients (22.6%). Two patients underwent endoscopic balloon dilatation with no success. The locations of lesion were the stomach, the duodenum and both in 9, 20 and 2 cases, respectively. There were operative complications in 13 cases (41.9%), recurrent ulcers in 2 cases (6.5%), and reoperations in 4 cases. The mean Visick score was 1.8 (1~4). There were no statistically significant clinicopathologic differences between the bypass operation group and the resection group. The two groups had 1 case each of recurrence. Although the bypass group had a greater complication rate (83.3%) than the resection group (32%), this was not statistically meaningful (P=0.175). The mean Visick score was 3.0 in the bypass group and 1.6 in the resection group, so the resection group was better (P=0.001). Conclusion: For a case of chronic peptic ulcer with outlet obstruction, even though it has been reported that endoscopic balloon dilatation worked well, surgery is still regarded as an important treatment. If you consider the patients' satisfaction and the difficulty of diagnosing malignant ulcers, surgical resection should be recommended more often than a bypass operation.

  • 편측 성대마비의 음성개선을 위하여 현재까지 알려진 치료방법은 teflon 또는 silicone 주입술, 외과적 성대 내전술, 갑상연골 성형술, 신경재식술, 등이 있으며, 근래까지는 Teflon 또는 Gelform 주입술이 제일 효과적인 방법이라 알려져 있으나, 이는 음의 높낮이 조절능력의 한계가 있고, 신경재식술의 결과 역시 만족스럽지 못한 경우가 많다. 따라서 저자는 발성기능의 생리학적인 측면에서, 보다 효과적인 음성개선의 방법을 찾기 위하여, 사람의 후두와 비교적 유사한 특성을 가진 개를 사용하여 실험을 하였다. 반회신경을 절단하여 편측 성대 마비를 유발한 뒤, 동측의 유일한 외전근인 후윤상피열근을 절제후 절단된 신경을 문합하여, 성대의 외전근 작용의 소실과, 발성시에 주로 작용하는 내전근만의 작용을 유도하여, 공동운동의 차단과, 내전운동의 향상을 기대하였다. 본 실험에 앞서, 임의적으로 신경을 자극시킬 수 있는 신경자극기와, 주위조직으로부터 신경만을 분리하여 자극할 수 있는 전극을 개발하여 사용하였으며, 또한 성대의 발성음을 임의대로 유발시킬 수 있는 생체 내 후두발성 모형(in vivo laryngeal phonation model)을 Moore(1987, 1988)등이 발표한 모형을 토대로 자체 개발하여 사용하였다. 실험은 13마리의 개를, 반회신경 절단군(3 마리), 반회신경 절단 및 후윤상피 열근 절제군(3 마리), 후윤상피열근 절제군(3 마리), 반회신경 문합 및 후윤상피 열근 절제군(4 마리)등으로 나누어 실험하였으며, 3 개월 후, 현수후두경, 후두 내시경, videolaryngoscopy, 신경자극 검사 등으로 성대의 내전운동 및 위치 변화의 관찰, 발성음의 음향분석 및 갑상피열근의 형태학적 변화를 관찰하여 다음과 같은 결과를 얻었다. 1. 반회신경 절단군과 반회 신경 절단 및 후윤상피열근 절제군은, 수술후 3 개월에 성대의 움직임이나 각도의 변화가 없었으며, 음향분석 결과 발성음이 아닌 잡음만이 포착되었다. 즉, 절단된 신경의 문합 없이 후윤상피열근 절제 만으로는 음성개선은 기대할 수 없었다. 2. 후윤상피열근 절제군에서는 수술 후 3 개월에 정상적인 성대의 내전운동이 관찰되었으며, 음향분석상 기본주파수 동요율 및 발성음의 강도는 약간의 증가를 보였다. 즉, 반회신경이 절단되지 않은 상태에서 후윤상피 열근 만을 절제하면, 발성음의 변화는 거의 없었다. 3. 반회신경을 절단후 문합하고 후윤상피열근을 절제한군 에서는 수술후 3 개월에, 성대의 정상적인 내전운동을 보였고, 음향분석상 수술직후에는 잡음만이 포착되었으나, 3 개월 후에는 잡음이 아닌 발성음을 들을 수 있었으며, 이 발성음의 기본주파수 및 강도는 수술전보다 감소되어 있었으나, 기본주파수 동요율은 증가되어 있었다. 즉 이 술식으로 인한 뚜렷한 발성음의 향상이 있었다. 이상의 결과로 미루어, 편측 신경 절단으로 인한 성대마비시, 절단된 신경을 봉합하고 성대의 유일한 외전근인 후윤상피열근을 절제하면, 공동운동의 차단과, 내향운동의 향상으로, 음성개선에 효과적이라고 사료되었으며, 이 방법이 편측 성대마비 환자의 효과적인 음성개선의 치료방법의 하나로 응용될 수 있으리라 생각된다.

  • Purpose: Endoscopic ultrasonography (EUS) is a useful imaging procedure for the diagnosis of submucosal tumors in the stomach. The present study investigated the EUS features of benign and malignant gastrointestinal stromal tumors(GISTs) and assessed differences between the two groups. Materials and Methods: Thirty patients with a GIST in the stomach were included in the study (23 benign and 7 malignant GISTs). We compared characteristic EUS findings (tumor size, location of tumor, regularity of the outer margin, echoheterogeneity, presence of cystic spaces, echogenic foci and mucosal ulceration) between benign and malignant GISTs. Results: Tumor sizes over 40 mm were observed in $85.7\%$ of the malignant and $8.7\%$ of the benign tumors (P=0.000). Intralesional cystic spaces were noted in $71.4\%$ of the malignant and $8.7\%$ of the benign tumors (P=0.003). The outer margin was irregular in $71.4\%$ of the malignant and $8.7\%$ of the benign tumors (P=0.014). $85.7\%$ of the malignant and $13.0\%$ of the benign tumors had an echo-heterogeneity in the tumor (P=0.001). The locations of tumor and the presence of echogenic foci or mucosal ulcerations were not different between the two groups. Conclusion: Tumor sizes over 40 mm, intralesional cystic spaces, irregular outer margins, and echo-heterogeneity in the tumor were significantly more frequent in malignant GISTs. EUS can provide informations in differentiating benign from malignant GISTs.

  • Background: The radial arteries are being used more often for coronary artery bypass grafting, We tried to the endoscopic radial artery harvest to reduce the cosmetic problems and neurologic complications of the conventional open harvesting and report the techniques and early results. Material and Method: The 86 patients underwent coronary artery bypass grafting between May 2003 and April 2005 had their nondominant radial artery endoscopically removed through a 2 cm incision at the wrist. The radial pedicle was dissected and was divided at antecubial area through a 5 mm counterincision. Result: The 23 patients complained of neuralgias on territory of superficial raidal none but no one complained of neuralgias on territory of lateral antebrachial cutaneous none. There was no functional impairment of the hand. There was no wound complication except a localized hematoma. All patients were contacted by telephone after postoperative 7.9$\pm$3.6 months. The 4 patients still complained of neuralgia. All the patients were satisfied with the aesthetics of the wounds. The multidetectional tomography was done on the 66 patients for the estimation of early patency of radial artery. There were 2 cases of stenosis and a case of occlusion. Conclusion: Endoscopic radial artery harvest had no functional impairment of the hand, lesser rate of neurologic complications and outstanding aesthetics. The results of early patency of the radial artery was similar to conventional methods. Therefore, we think that endoscopic radial artery harvest is the optimal procedure.

  • The dilated haustra of colon after esophagocolostomy was a rare complications, but it may be extremely dangerous because of the potential for perforation of the thin- walled esophageal substitute. Therefore a prompt surgical correction of the lesion should be done. The conventional surgical exploration and resection of the lesion site was very difficult. The use of the ends GIA to eliminate the dilated haustra of colon was simple and safe method and the postoperative results were good. We report a case of experience and methods.
