A clinical study was performed on 152 cases of surgical esophageal disease treated by the Department of Thoracic & Cardiovascular Surgery of Korea University Hospital from Jan. 1989 through July 1994. The most common esophageal disease was cancer which was seen in 73 cases (48%) among 152 cases. All were treated surgically' 52 patients (71%) were managed by curative or palliative resection with reconstruction and feeding gastrostomy or jejunostomy, otherwise Celestine tube insertion was performed on the remaining 21 patients for palliatio'n. Esophageal leiomyoma occurred in 6 cases(3.9%), among them 1 case was performed with trio recoscopic enucleation . Achalasia were in 7 cases (4.6%) and was treated with modified Heller's m otomy and with Belsey Mark IV operation. Diverticulum were in 11 cases (7.2%). Esophageal stricture occurred in 20 cases (14.1 %) and 17 of 20 cases were managed with bypass surgery. Esophageal perforation was seen in 20 cases, its cause was instrumental trauma in 7 cases, stab wound in 4 cases, foreign body in 4 cases, spontaneous perforation in 3 cases, and others 1 case Other disease including congenital lesion was seen In 1 Scases. 고려대학교 흉부외과학 교실에서는 최근 5년간(1989년 1월∼1994년 7월) 외과적 치료를 시행했던 152례의 식도환자를 대상으로 악성 종양, 양성 종양, 운동성 장애 질환(식도 게실 및 무이완증), 협착, 천공 및 선천성 질환으로 분류 임상분석을 시도하였다. 가장 많았던 질환은 악성종양이며 총 73례로, 전체환자의 48%를 차지하였다. 이중 71%인 52례의 경우에서 식도의 절제 및 재건술을 시도하였고, 나머지 경우에 있어서 위루 성형술, 공장루 성형술 및 식 도관 삽입을 시행하였다. 남녀 비는 남:여 65.8이 었으며, 평균나이는 58.7세였다 이중 합병증으로 인한 병원내 사망례는 5례로 7.8%이며, 합병증으로는 문합부 누출이 가장 많았다. 양성종양은 모두 평활근종으로 6례 (3.9%)였으며, 이중 1례의 경우 흉강경을 이용한 적출술을 시행하였다. 운동성 질환중 식도무이완증(Achalasia)이로(4.6%), 변형된 Hello이 근절개술을 시행하였고, 3례는 Belsey Mark IV 수술을 동반하였다. 게실은 11례 (7.2%)였다 식도협착은 20례 (14.1%)로 대부분이 부식제 섭취에 의한 협착이었으며, 이중 17례에서 위나 대장을 이용한 재 건술을 시행하였다. 식도천공은 20례 (14.1%)였으며 이중 내시경등에 의한 외부손상례가 가장 많았고(15례), 수술방법으로는 천공부위의 일차봉합이 가장 많았고(8례), 6례의 경우 격리 우회술을 시행하였으며, 이중 사망례는 없었다 선천성질환이 6례 (3.9%)였고,나머지 기관-식도루등의 기타질환이 9례(5.9%)였다.

Blood flow in carotid arteries becomes unstable when stenosis is severe. The stenosed carotid artery induces the onset of turbulence in the post-stenotic region, which may significantly damage the endothelial cells. Here, we conduct a direct numerical simulation in a stenosed carotid artery to explore the transitional flow in the post-stenotic region. The pulsatile boundary condition is applied at the inlet of the stenosed carotid artery. The results demonstrate that transitional behavior happens between the acceleration and deceleration phases. It is shown that negative wall-shear stress (WSS) frequently occurs in this section. To quantify this behavior, we examine the probability density function of the WSS event. We further analyze the relationship between the negative WSS and the oscillatory shear stress index.

Intralobar pulmonary sequestration is a rare congenital lung anomaly. It is defined as a portion of nonfunctioning lung parenchyma that receives its blood supply from an anomalous systemic artery. Patients often present with chronic or recurrent pneumonia. A chest radiograph may show a cystic lesion with air-fluid levels in the lung base. A high index of suspicion is needed for a diagnosis. Surgical removal of a symptomatic intralobar pulmonary sequestration is generally the treatment of choice. Identifying the aberrant artery is a difficult problem when resecting a pulmonary sequestration. The thoracic and abdominal aortas are the most common origins for the abnormal blood supply. However, arterial supply from the celiac artery is quite rare. We present a case of intralobar pulmonary sequestration with the blood supply originating from the celiac artery.

In the injury of shoulder girdle, as a matter of accurate diagnosis through inpection, palpation, nervous examination, and medical program following an injury state, we can recover and take part in the sports as quickly as possible. Rehabilitation treatment should be conducted right after injury, and during the injury treatment, its method should be conducted in many ways after close observation and analysis of recovery state. Especially therapeutic exercise in the recovery is very important, because shoulder girdle has larger ROM than other part. For the prevention of injury in shoulder girdle, we should know functional-anatomical view, take moderate technique training, and have sufficient muscle exercise, stretching, and warming-up. And hard training with protection equipment needs wearing and checking fittable equipment, and should be reduced injury by precise technique during the game, with sufficient exercises.
