Background: The use of the stapler n esophageal reconstruction after esophageal resection for benign or malignant esophageal diseases has become popular because it has less leakage at the anastomotic site and shorter operation time than manual sutures. However, the use of classic circular stapler has some complications such as stenosis and dysphagia that requires additional treatment. Such complications are closely related to the inner diameter of the anastomotic sites. In this study, the diameter of anastomotic site was compared after the use of circular stapler(EEA) and straight endoscopic stapler(endo GIA). Material and Method: The patients who received esophageal reconstruction by stapler from August 1995 to September 1997 were reviewed. The patients were divided into 2 groups. One group need the circular stapler, and the other group the straight endo GIA(14 cases with endo GIA 30mm, 24 with endo GIA 45mm). After a cervical esophago-enteric anastomosis, the stricture of anastomotic site and the incidence of dysphagia were compared between the 2 groups using an esophagography and the patient's symptoms. The follow-up period was 12months in average. Result: In the former group in which the circular stapler was used, 2 cases of anastomotic stenosis were reported. In comparison, none were reported in the latter group. Dysphagia were reported in 8 cases of the former group, and in 3 cases of the latter group(1 case in endo GIA 30 mm, 2 cases in endo GIA 45 mm). Conclusion: The use of endo GIA in esophago-enteric anastomosis resulted in a wider diameter of the anastomotic site, lesser stricture, and lesser incidence of dysphagia compared to the use of former circular stapler. Therefore, it is thought to be a better method in esophageal reconstructions.

최근 흉강경 수술수기 및 기구의 발달로 본태성 안면 다한증 치료에 대한 흉강경을 이용한 교감신경절 절제술은 안전하고 효과가 우수한 치료방법으로 적용이 늘고있다. 고려대학교 안암병원 흉부외과에서는 1996년 7월부터 1997년 4월까지 본태성 안면 다한증을 호소한 43명의 환자를 대상으로 비디오 흉강경을 이용한 하부성상 교감신경절 절제술을 시행한 후 효과를 조사하였다. 대상이된 환자들의 성별은 남자가 33명 여자가 10명이었으며, 평균 연령은 37세였고, 다한증 부위는 순수 안면 다한증 23례, 수부 및 족부동반 안면 다한증 20례였다. 수술부위는 하부성상 교감신경절 절제술 12례, 하부성상 교감신경절 및 제 2번 흉부 교감신경절 절제술 28례였으며, 하부성상 교감신경절 및 제 2번, 3번 흉부 교감신경절 절제술이 3례였다. 수술후 합병증으로는 흉부 통증 8례, 안검하수 4례, 기흉 1례있었다. 보상성 다한증은 36례(83.7%)에서 발생하였으며, 부위별로는 체간 19례, 대퇴부 3례, 족부 2례, 체간 및 대퇴부 10례, 체간 및 족부가 2례발생하였다. 수술결과는 퇴원후 3개월 이상 경과후 추적관찰 결과 다한증 증상에 있어 32례(74.4%)에서 매우 호전을 보였고 11례에서 수술전보다 호전을 보였으며, 만족도에서도 "만족한다"가 33례(76.7%), "대체로 만족한다"가 8례(18.6%)였으며 "불만족"도 2례(4.6%)에서 조사되었다. 본태성 안면 다한증에서 비디오 흉강경을 이용한 하부성상 교감신경절 절제술은 증상 호전에서 만족할만한 결과를 보였으나, 보상성 다한증은 수술후 만족도를 저하시키는 주된 부작용으로, 이에 대한 개선 연구가 필요하다. With recent advancements in the instrumentation and technique of VATS, it has become the method of choice to cure facial hyperhidrosis. From July 1996 to April 1997, we performed 43 thoracic lower stellate ganglionectomy with VATS for facial hyperhidrosis. There were 33 men and 10 women whose ages ranged from 17 to 63 years(mean age, 37 years). Of those patients, 23 complained only of facial hyperhidrosis, and 20 complained of facial hyperhidrosis along with excessive sweating of the palm or foot. Thoracoscopic sympathetic ganglionectomy procedures included lower stellate ganglionectomy in 12 patients; lower stellate ganglionectomy and T2-sympathetic ganglionectomy in 28 patients; and lower stellate, T2 and T3 sympathetic ganglionectomy in 3 patients. Common complications were compensatory hyperhidrosis(36 patients) and causalgia(8 patients). At the end of the follow-up period(minimum, 3 months) ninety-five percent of the patients reported satisfactory results. Thoracic lower stellate ganglionectomy with VATS is an efficient, safe and minimally invasive surgical procedure for facial hyperhidrosis.

경막외마취하에 비디오 흉강경수술 - 고위험군에서

이송암,김광택,김일현,박성민,백만종,선경,김형묵,이인성,Lee, Song-Am,Kim, Kwang-Taik,Kim, Il-Hyeon,Park, Sung-Min,Baek, Man-Jong,Sun, Kyung,Kim, Hyoung-Mook,Lee, In-Sung 대한흉부심장혈관외과학회 1999 Journal of Chest Surgery (J Chest Surg) Vol.32 No.8

배경: 비디오 기술의 발전과 내시경의 향상으로 비디오 흉강경수술은 기흉, 다한증 및 종격동 종양 같은 몇 몇 질환에서는 표준 수술로서 인정받고 있다. 이러한 비디오 흉강경수술은 전신마취하에 이중기도관에 의한 일측 폐환기가 필요하였다. 그러나 폐질환이 동반된 환자나 전신상태가 나쁜 고령의 환자와 같은 고위험군 의 경우는 일측 폐환기나 전신마취 자체에 대한 위험성이 높다. 대상 및 방법: 1997년 12월부터 1998년 7월 까지, 전신상태가 나빠서 전신마취가 위험한 8례의 환자를 대상으로(농흉 6례, 난치성 흉수 1례, 간질성 폐섬 유증 1례) 경막외마취하에 자가호흡을 유지한 상태에서 비디오 흉강경을 이용하여 흉강내 질환의 진단 및 치료를 시행하였다. 결과: 7례에서 성공적으로 비디오 흉강경수술이 시행되었다. 수술 도중 호흡기능이 저하 되어 전신마취로 전환한 경우가 1례 있었으나 개흉술로 전환한 경우는 없었다. 만성 농흉 환자 2례의 경우 에서, 1례는 재발하여 다시 비디오 흉강경 배농술을 시행하였으며 1례는 수술 후 7일째 흉곽성형술을 시행 하였다. 수술시간은 평균 31.8$\pm$15.2분이었으며 수술 후 호흡합병증이 발생한 경우는 없었다. 결론: 경막외마 취하에 비디오 흉강경을 통한 진단 및 치료는 고위험군에서 안전하게 시행될 수 있는 기법이라고 사료된다. Background: Video-assisted thoracoscopic surgery has become a standard therapy for several diseases such as pneumothorax, hyperhidrosis, mediastinal mass, and so on. These methods usually required single-lung ventilation with double-lumen endobronchial tube to collapse the lung under general anesthesia. However, risks of general anesthesia itself and single-lung ventilation must be considered in high-risk patients. Material and method: Between December 1997 and July 1998, eight high-risk patients (6: empyema, 1: intractable pleural effusion, 1: idiopathic pulmonary fibrosis) with underlying pulmonary disease and poor general condition were treated by video-assisted thoracoscopic surgerys under epidural anesthesia and spontaneous breathing. Result: Video-assisted thoracoscopic surgerys were successfully per formed in 7 patients. Conversion to general anesthesia was required in 1 patient because of decrease in spontaneous breathing. But, conversion to open decortication was not required. In two patients with chronic empyema, one patient required thoracoplasty as a second procedure and one patient required re-video-assisted thoracoscopic procedure due to a recurrence. The mean operative time was 31.8$\pm$15.2 minutes. No significant postoperative respiratory com plication was encountered. Conclusion: Video-assisted thoracoscopic surgerys can be per formed safely under epidural anesthesia for the treatment of empyema and diagnosis of pulmonary abnormalities in high-risk patients.

Authors developed the patent database mangement system for oral and maxillofacial surgery, using a IBM compatible personal computer and a spreadsheet database program Excel . We adopted the automatic diagnosis-description system, which required less input load errors, using tips that could help users manage clinical data with ease. It did serve an easy accumulation of clinical data and a rapid searching for wanted data during our clinical study. On our way for the development, we realized that we need a new standardized classification of diseases and operations that are fit to our situations, which would let us have great chances to develop our clinical patient management system.

Tensile strength and failure process of composite materials depend on the variation in fiber strength, matrix properties and fiber-matrix interfacial shear strength. A Monte-Carlo simulation considering variation in these factors has been widely used to analyze such a complicated phenomenon as a strength and simulated the failure process of unidirectional composites. In this study, a Monte Carlo simulation using 2-D and 3-D(square and hexagonal array) model was performed on unidirectional graphite/epoxy and glass/polyester composites. The results simulated by using 3-D hexagonal array model have a good agreement with the experimental data which were tensile strength and failure process of unidirectional composites.
