We treated 654 patients with simultaneous bilateral sympathectomy for essential hyperhidrosis from March 1989 to September 1997(354 males and 300 females). The exposure afforded by thoracoscopy is actually superior to that seen at the time of either thoracotomy or axillary thoracotomy. The use of single-lumen intubation with alternating partially collapsed lung by CO2 inflation resulted in shorter anesthesia, shorter operative time, and shorter hospitalization. 2-mm extended thoracoscopic T2-sympathectomy is not only a time-saving method but also a very simple and effective one in the treatment of hyperhidrosis by experienced surgeons. The modification on our technique of thoracoscopic sympathectomy as described allowed us to significantly improve our previous results. A majority of the patients were relieved, and over 95% were satisfied initially.

근래 골조직에 있어서 자율신경의 기능에 대하여 많은 연구가 이루어지고 있으며, 골내의 자율신경의 해부학적 분포는 많이 알려져 있다. 그러나 임상적으로 반사적 교감신경 이상이나 레이노드 현상등과 같은 교감신경의 기능이상증에서나, 버거씨병 등의 치료 목적으로 시행되고 있는 교감신경 절제술 후, 자율신경기능의 변화가 사지골의 혈류나 골대사에 미치는 영향에 대하여는 아직도 논란의 여지가 있다. 저자들은 교감신경절제술 후 시간 경과에 따른 골에 미치는 영향을 알아보기 위하여 흰쥐에서 골대사와 혈류상태를 비교적 충실히 반영하는 정량적 골스캔을 시행하였다. 체중 $300{\sim}400g$의 수컷 흰쥐 10마리에서 복강을 통한 편측 요추부 교감신경절제술을 시행하였고, 수술 전과 후 1일, 3일, 1주, 2주, 3주, 4주에 양측 하지에서 각각 골스캔을 시행하고 교감신경 절제측 하지와 정상 하지에 대칭적으로 관심구역을 정하여 양측의 골스캔상 섭취계수를 비교하였다. 측정부위는 각 하지의 대퇴골간, 경골간 및 중족골로 하였다. 교감신경 절제술을 시행한 하지에서는 골스캔 소견상 수술 후 1일 또는 3일부터 동위원소 집적이 유의하게 증가되었으며 원위부로 갈수록 더욱 증가되었다. 그러나 3주 이후에는 정상측 수준으로 환원되었다. 교감신경절제술 후 골스캔상 동위원소집적이 증가되는 것은 골자체의 혈류가 증가되기 때문이며 이차적으로 골의 흡수를 유발하여 골밀도가 감소하는 것으로 생각되는데 이러한 변화는 시술 후 1일 째부터 관찰되어 사지골이 교감신경 절제에 매우 민감하게 반응하는 것을 알 수 있었다.9m}Tc$-MAA를 이용한 간 동맥 혈류 검사는 간암에서 색전술의 효과를 정확히 평가할 수 있는 유용한 검사법으로 이용될 수 있으리라 생각한다. 활성화 과정을 알아볼 수 있었으며 위상영상히스토그램을 통하여 이를 정량화하여 심실내 전기적 활성의 비동시성 여부를 추적관찰 할 수 있는 비관혈적검사임을 확인하였다.며, 3. $^{99m}Tc$으로 표지된 avidin과 streptavidin은 먼저 간으로 흡수된 후 대사된 다음 신장으로 배설된다는 사실을 알았다.damole에 의한 부작용은 흉통, 두통, 복통 등의 순이었고 전예에서 호전되었으며 생명에 위험을 초래할 수 있는 정도의 심장마비나 심부정맥은 한 예에서도 없었다. 결론적으로 dipyridamole은 약물부하 심근 SPECT 검사에 안전하게 사용할 수 있는 약물로 사료된다. 미소핵 빈도수가 증가하는 경향을 보였으나, 각 군간에 통계학적으로 유의한 차이는 없었다(p>0.05). 결론 : 임상적으로 치료를 중단하게 되는 1000mCi/60 Kg(16.67 mCi/Kg)를 투여한 군에서도 생쥐 골수내 미소핵이 발현되지 않는 것으로 보아, 방사성옥소는 비교적 안심하고 치료에 사용할 수 있는 제제로 사료되었다.반드시 비례하지만은 않아서 시간경과에 따른 추후 검사가 필요하리라 생각된다. 또한 방광요관역류가 있는 환아에서 DMSA 섭취율로 신기능을 평가할 때, 특히 영유아에서 연령에 따른 고려가 있어야 할 것으로 보인다.었다. 4) $^{99m}Tc-DISIDA$ hepatobiliary scintigram 음성율을

Background: Thoracoscopic R3 (above the third rib)sympathicotomy has been performed as an effective method in treating palmar hyperhidrosis because it is effective in eliminating the symptoms of hyperhidrosis and has lower degree of compensatory hyperhidrosis than that of sympathectomy. Most of the results published were based on the short-term follow up. So we evaluated the intermediate term follow up results of the R3 sympathicotomy. Material and Method: From April 1999 to August 2001, ninety-four patients with palmar hyperhidrosis had been treated by R3 sympathicotomy at the Inha University Hospital. Follow-up study was completed for 76 patients (male 38, female 38) and average follow-up period were 25$\pm$9.1 (15∼50) months. The sympathetic trunk passing above the upper border of third rib was divided by electric cautery. The patient's satisfaction after surgery was estimated using the analogue scale from score 0 to 100 (100 means perfect satisfaction). Result. The scale of patient's satisfaction immediately after operation was 92.36$\pm$9.93. After 15 months, the scale of satisfaction was decreased to average 71.80$\pm$20.24 and it is statiscally significant. The cause of dissatisfaction were compensatory hyper-hidrosis and recurrence of symptom. The degree of sweating immediately after operation was mean 0 and after 15 months it increased to mean 1.5. The degree of the compensatory hyperhidrosis immediately after operation was mean 1 and it increased to mean 5 after 15 months. Conclusion: R3 sympathicotomy has excellent therapeutic results immediately after operation but therapeutic effectiveness is becoming to decrease 15 months after operation. The common causes of dissatisfaction are compensatory hyperhidrosis and recurrence of hyperhidrosis.

Background: Thoracoscopic sympathetic block in palmar hyperhidrosis has merits in its immediate responsiveness and recovery. In palmar hyperhidrosis, the level of sympathetic chain to be blocked has been somewhat obscure. Materials and methods: To compare the results of T2 with T2,3 sympathetic block, we retrospectively studied 192 patients (T2 group: 84, T23 group: 108) operated on at SNUH with palmar hyperhidrosis between April 1994 and July 1997. We reviewed medical records and recently interviewed the patients by telephone call. Sex and age distribution between two groups showed no significant differences. We performed sympathectomy at the early phase of the syudy until April 1997, and after then, we adopted sympathicotomy rather than sympathectomy. Results: All patients showed symptomatic improvement after the operation. Mean operation times of T2, T23 groups were 61.3$\pm$22.5min, 82.7$\pm$24.8min, respectively(p<0.01). Early postoperative complications, such as Horner's syndrome or chest tube insertion, were not different in two groups. There were no statistical differences of late complications such as compensatory truncal hyperhidrosis, gustatory sweating, and phantom sweating. No patient experienced recurrence of palmar hyperhidrosis during the study period. The only difference was the extent of compensatory truncal hyperhidrosis. The compensatory sweating occurred from axilla to suprapatella in T2 group whereas its extent was from nipple to suprapatella in T23 group. Conclusions: We concluded that T2 thoracic sympathetic block is mandatory for the treatment of primary palmar hyperhidrosis.

Background: It has been known that the most effective treatment method of hyperhidrosis is video-assisted thoracoscopic sympathetic nerve block. Postoperative compensatory hyperhidrosis and anhidrosis are major factors that decrease the postoperative satisfaction. Although sympathetic rami have been selectively blocked to decrease the complications, technical difficulties and excessive bleeding have prevented the universal application. Material and Method: Three pre-fixative cadavers were dissected before clinical application. Bilateral sympathetic chains were exposed in supine position after the whole anterior chest wall was removed. Second and third sympathetic rami were blocked using clips. After the sympathetic chains including ganglia were removed, we evaluated the extents of rami block. Twenty-five patients were subjected to the clinical application. Surgeries were performed in semi-fowlers position under general anesthesia and bilateral ventilation. 2 mm thoracoscopy and 5 mm trocar were intro-duced through third and fourth intercostal space, respectively. Second and third sympathetic rami were blocked using thoracoscopic clips. The postoperative complications, satisfaction, and compensatory hyperhidrosis rate were evaluated retrospectively. Result: Sympathetic rami were completely blocked in cadaver dissection study Hyper-hidrosis symptom was improved in all patients without operative complication. Operative time was shorter than that of traditional ramicotomy. All patients, except four, were satisfied with postoperative palmar hyperhidrosis. Com-pensatory hyperhidrosis was more severely happened in fifteen patients (60%). The remaining six patients had no complaint. Two patients had a minimal degree of gustatory hyperhidrosis. Conclusion: This operative method had shorter operative time and less complication rate, compared with traditional ramicotomy Operative success rate was similar to the traditional syrnpathicotorny; lower extent and occurrence rate of compensatory hyperhidrosis. The thoracic sympathetic rami clipping was suggested as an alternative method for treatment of palmar hyperhidrosis.

Background: Thoracic sympathectomy for hyperhidrosis has been recognized as an effective treatment using thoracoscopic devices and operative techniques, but the satisfaction has decreased due to a compensatory hyperhidrosis. Therefore, the postoperative results and compensatory hyperhidrosis were analyzed. We also measured the temperature differences in the hand and foot during the preoperative and postoperative periods and measured the blood flow of upper and lower extremities. Material and Method: From December 1995 to July 1998, total of 47 patients with hyperhidrosis underwent sympathectomy via VATS at the Department of Thoracic and Cardiovascular Surgery, Kangnam St. Mary's Hospital. The patients were evaluated for preoperative and postoperative temperature changes on the finger and toe, and preoperative and postoperative blood flows were measured by the Doppler examination on the digital artery, radial artery and dorsalis pedis artery. Result: There were no operative deaths but some complications existed: 7 pneumothorax, 3 recurrence and 1 Honor syndrome. Ninety-five percent of the patients also had compensatory sweating especially in the trunk. There were 5 patients who regretted recurring the operation because of the compensatory sweating. Sweating decreased in 46% of the sole hyperhidrosis patients. The temperature difference between preoperation and postoperation was 1$^{\circ}C$ on the right hand side and 1.9$^{\circ}C$ on the left hand side(P<0.05). There was no significant temperature difference on the sole. Blood flow increased significantly in the palm, but no difference in the sole. Conclusion: In conclusion, thoracic sympathectomy for hyperhidrosis is a safe and effective treatment but satisfaction has been decreased by the compensatory sweating; therefore, it is important to thoroughly explain the compensatory sweating prior to surgery. Improvement of the plantar hyperhidrosis is not due to a physiological change, but to a psychological stability.

Thoracic sympathectomy is the radical and definite treatment of palmar hyperhidrosis. From January 1992 to March 1997, 4 patients with recurrent hyperhidrosis underwent resympathectomy via VATS at the Department of General Thoracic and Cardiovacular Surgery, Young Dong Severance Hospital. There were 2 men and 2 women and mean age was 20.0 years. There were moderate to severe adhesions at previous resection site but no thoracotomies were performed. There was no sweating on palms in all cases and all patients were greatly 5,Btisfied with those results postoperatively. In conclusion, recurrent hyperhidrosis was successfully treated with resympathectomy via VATS. In order to prevent recurrence and minimize the postoperative complication, the proper localization of the 2nd sympathetic ganglion and the radical excision of anatomical variation including Kuntz fiber are needed.

Background: Facial hyperhidrosis patients have as much difficulty in personal relationships as the palmar and axillary hyperhidrosis patients. There have been no appropriate treatment, but recently, satisfactory results have been obtained through sympathetic blockade. Thoracoscopic thoracic sympathectomy for facial hyperhidrosis has been known to resect cervicothoracic (stellate) ganglion, but its inherent complications such as Horner syndrome have made the surgeons hesitant to use this method. We, through our experiences in treating palmar and axillary hyperhidrosis for the past 6 years, believed that T2 sympathicotomy would be enough for facial hyperhidrosis and have experimented and obtained satisfactory results. Material and Method: From June 1997 to May 1998, 38 consecutive patients underwent bilateral thoracoscopic T2 sympathicotomy with 2mm instruments at Seoul National University Hospital. Result: All patients were relieved of excessive sweating in their faces immediately after the operation. Postoperatively, 5 patients (13.2%) required insertion of chest tubes because 3 had incomplete reexpansion of the lung, and 2 had hemothorax from severe adhesion. Other complications related to the surgical procedures, such as Horner's syndrome, and brachial plexus injury, were not detected in any cases. The mean hospital stay was mean 1.7$\pm$0.9 days after surgery. Conclusion: T2 sympathetic ganglion is the appropriate resection site for facial hyperhidrosis, and complications such as Horner syndrome can be prevented by not cutting the stellate ganglion. In addition, it is possible to perform the operation by using a 2 mm thoracoscopic instrument, and may obtain much better results.

Backgrouds: It is almost universally accepted that occlusive vascular diseases are best managed by anatomical reconstruction. However, the mortality and the morbidity have limited this operation for patients with high operation risks. In these patients, palliative operations such as extra-anatomic bypass and lumbar sympathectomy, are accepted as useful treatment. Material and Method: A retrospective study was conducted in 38 patients who underwent palliative operations for occlusive vascular disease at Korea University Guro Hospital between 1996 and 2000. Mean age of the patients was 60.37 $\pm$ 17.65 years, and preoperative diagnoses were atherosclerosis in 32 patients, Buerger's disease in 4 patients, Raynaud's syndrome in 1 patient and SVC syndrome in 1 patient. Result: Extra-anatomic bypass(40procedures), lumbar sympathectomy(17), thromboembolectomy(7) and femoral artery graft interposition(1) were performed. Six patients were required reoperation due to graft flow failure or fistula. Three year primary patency rate of entire operations was 78.29 $\pm$ 8.81%, and the correlation between type of operation and patency rate was not statistically significant. Conclusion: Palliative operations for occlusive vascular disease are useful treatment in limited patients with high operation risks or limited life expectancy.
