Objective : Thoracoscopic T2 sympathicotomy had been performed as a simple and effective method in treating palmar hyperhidrosis, but some patients are not satisfied with the result of sympathicotomy due to compensatory hyperhidrosis. Therefore, a more limited T2 sympathicotomy using 2mm endoscope was introduced. We made a comparison between conventional T2 sympathicotomy and limited T2 sympathicotomy on operative results and compensatory hyperhidrosis. Material and Method : From January 1998 to April 2000, 56 patients were treated by video assisted endoscopic thoracic sympathicotomy. Thirty patients of these underwent T2 sympathicotomy(Group A), and the remainders underwent limited T2 sympathicotomy(Group B). The limited T2 sympathicotomy is coagulation of the interganglionic fibers of T2 sympathetic ganglion on T2 rib head. The comparative analysis between two groups was based on the medical records and telephone interview results. Result : All patients were treated for excessive sweating on palms with 2mm endoscopic sympathicotmy. There were no mortalities, life-threatening complications except one recurrent patient who was treated successfully with reoperation( endoscopic sympathicotomy). Compensatory hyperhidrosis was common in group A. An individual satisfactory rate for the operations was higher in group B than in group A. Conclusion : The limited T2 sympathicotomy considered to be a more effective and less complicated method than the T2 sympathicotomy for the treatment of palmar hyperhidrosis.

Background: Conventional thoracoscopic sympathectomy or sympathicotomy is an effective method in treating localized hyperhidrosis; however, this may result in a postoperatively compensatory hyperhidrosis or facial anhidrosis in the treatment of palmar hyperhidrosis. We modified the conventional sympathicotomy by limiting the extent of nerve transection (limited T3 sympathicotomy) since May 1998. However, there are many reports of a good short-term outcome of limited T3 sympathicotomy. Therefore, we reviewed long-term follow-up of limited T3 sympathicotomy based on outcomes analysis using a questionnaire. Methods: Fifty four patients with palmar hyperhidrosis underwent a limited T3 sympathicotomy between May 1998 and March 1999 and had a complete follow-up over two years using a questionnaire (the mean follow-up was 2.6 years). The patients' postoperative satisfaction was determined by their subjective responses to the questionnaires; the degree of compensatory hyperhidrosis, the effects on foot hyperhidrosis, gustatory hyperhidrosis and facial dryness, and recurrence, and patient's satisfaction. Results: Of the total, 87% of patients had a compensatory hyperhidrosis and 3.7% of them were disabled. 31.5% of patients showed improvement in foot hyperhidrosis, while 68.5% of patients demonstrated no change or got worse. 31.5% of patients had gustatory hyperhidrosis and facial dryness and 22.2% of patients showed a mild palmar hyperhidrosis. The postoperative patients' satisfaction was significantly in 96.3% of patients. Conclusions: The limited T3 sympathicotomy is a highly effective treatment of palmar hyperhidrosis and has a low rate of postoperative compensatory hyperhidrosis, gustatory hyperhidrosis, and facial dryness.

Video assisted thoracic sympathectomy or sympathicotomy is a safe and effective therapy for the treatment of palmar hyperhidrosis with immediate symptomatic imporvement. However the degree of satisfaction may diminish with time due to cmpensatory sweating or excessive hand dryness. Therefore by comparing and assessing the degree of symptomatic improvement or compensatory sweating following sympathectomy or sympathicotomy at various levels we aim to determine the optimal level of sympathetic nerve block which will result in minimal side effects and maximal benefit. Material and Method: Among 194 patients having undergone video assisted thoracic sympathectomy or sympathicotomy between January 1996 and June 1999, 137 patients who responded to either telephone interview or questionnaire were included in the current study. The patients were divided into three groups. Group I(n=61) ; patients having undergone T2,3,4 sympathectomy group II(35) ; patients having undergone T2 sympathicotomy and group III(41) ; patients having undergone limited T2 sympathicotomy which consist of block of interganglionic neuronal fiber on the third rib. The parameters studied comprised of pre- and post-operative palmar temperature change treatment satisfaction the degree of compensatory sweating or discomfort from palmar dryness postoperative complication and changes in plantar sweating Result : There was no difference in age and sex among the groups and the mean postoperative elevation in palmar temperature was 21.59$^{\circ}C$ without any differences among the groups. Patients expressing satisfaction were 65.6%, 62.9% and 90.24% in groups I, II and III, respectively(p<0.05) Moderate to severe compensatory sweating was present in 65.6% 51.4%, and 24.39%, in group I, II, and III, respectively(p<0.05) Slight but comfortable amount of palmar humidness was expressed in decreasing order group III(41.6%) group I(24.6%) and group II(5.7%) (p<0.05) Ineffectiveness or recurrence was present in 5patients in group I(8.2%) 1 patient in group II(2.9%) and none in group III. With regards to plantar sweating decrease in sweating was expressed in 43 patients(31.4%) while similar degree of sweating in 61 patients(44.5%) and increase in sweating in another 33 patinets(24.1%) Conclusion : Limited T2 sympathicotomy resection of the lower interganglionic neuronal fiber of the second sympathetic ganglion on the third rib showed immediate effect in palmar hyperhidrosis and caused lesser compensatory sweating and hand dryness.

배경: 국소적 다한증의 흉강경을 이용한 통상적인 흉부교감신경절제술이나 교감신경절차단술은 효과적인 치료법이기는 하나 수술 후 심한 보상성 다한증이 많이 발생 하고 수장부 다한증의 경우 수술 후 얼굴에서 땀이 나지 않는 부작용이 발생한다. 저자들은 기존의 수술법을 개량해 제한적 흉부교감신경절단술을 고안하였다. 본 연구는 제한적 교감신경절단술의 결과를 분석하였다. 대상 및 방법: 1998년 5월부터 8월 까지 17명의 환자들에게 제한적 흉부교감신경절단술을 시행하였다. 9명의 안면부 다한증인 환자들에게 두 번째 교감신경절 위 아래의 교감신경을 절단하던 기존의 방법과는 달리 첫번째 와 두 번째 흉부교감신경절 사이의 신경절간신경만을 절단하였다. 8명의 수장부 다한증 환자에 대해서는 두 번째와 세 번째 흉부 교감신경절간신경을 절단하였다. 결과: 17명의 환자들 중 16명의 환자에서 수술 후 원하던 부위의 땀이 나지 않았으나 1명의 환자는 수술 1달 후 얼굴의 땀이 재발하였다. 안면부 다한증으로 수술을 받았던 9명의 환자들 보상성 다한증으로 4명이 심하게, 4명이 중등도로, 1명은 경미하게 불편을 호소 하였다. 그러나 수장부 다한증으로 수술을 받았던 8명의 환자들 중에서는 보상성 다한증을 3명에서 중등도로, 1명이 경미하게 호소하였으며 4명은 보상성 다한증이 없었다. 결론: 제한적 흉부교감신경절단술은 최소 침투 수술법으로 효과적인 치료법이며 특히 수장부 다한증에서는 수술 후 체간에서 발생하는 보상성 다한증의 발생을 줄이고 얼굴의 무한증을 막을 수 있을 것으로 사료된다.

Objectives : Essential hyperhidrosis is a common condition characterized by excessive body sweating. Excessive sweating beyond what is necessary to maintain normal body temperature need not be considered pathological unless it interferes with one's occupation and/or life-style. The existing non-operative therapeutic options seldom give sufficient relief or show a transient effect. In this regard, the thoracic sympathectomy may provide a definitive cure. In the past, surgical procedures were highly invasive and caused significant morbidity, but the minimally invasive thoracoscopic procedure provided detailed visualization of sympathetic ganglia and is associated with minimally postoperative morbidity. Nowadays, thoracoscopic transthoracic sympathectomy is accepted as the treatment of choice for essential hyperhidrosis. In palmar hyperhidrosis, however, the level of sympathetic chain to be blocked has been somewhat obscure. It is assumed that the incidence of compensatory hyperhidrosis may closely related to the extent of thoracic sympathectomy. Material & Methods : To compare the results of posterior midline approach with endoscopic sympathectomy, and the results of T2 with T2, 3 sympathectomy or sympathicotomy, we retrospectively studied 62 patients treated for palmar hyperhidrosis between September 1993 and May 2000. We reviewed medical records and recently interviewed the patients by telephone calls. Results : The treatment effect of T2 sympathectomy is no different from T2, 3 sympathectomy. But, the incidence of compensatory hyperhidrosis is less in the T2 sympathectomy group than the T2, 3 sympathectomy group. Conclusion : Thoracoscopic sympathectomy is considered a simple, safe, and effective method for treating palmar hyperhidrosis, with a shorter operation time, fewer hospital days, and a better cosmetic result, as compared with the open approaches. However, sympathicotomy seems to provide the advantages of a limited extent of denervation and the resultant decrease of compensatory hyperhidrosis compared to sympathectomy.

안면다한증의 치료를 위해 교감신경 절제 혹은 클립 차단술이 널리 이용되고 있으나 보상성 다한증의 발생을 충분히 줄이지는 못하였다. 보상성 다한증을 줄이기 위해서는 교감신경 줄기를 보존하는 술식이 필요하다. 연세대학교 의과대학 영동세브란스병원 흉부외과에서는 2000년 1월부터 2002년 7월까지 안면 다한증 환자를 대상으로 시행한 T2 symphatectic clipping 22예(group 1)와 T2 ramicotomy 14예(group 2)를 대상으로 수술의 만족도, 얼굴의 건조도, 보상성 다한증 발생 유무, 보상성 다한증 정도 등을 후향적으로 비교 분석하였다. 얼굴의 건조 정도는 group 1에서 dry가 5예(22.7%), humid가 17예(77.3%), persist는 없었으며 group 2에서 dry가 2예(14.3%), humid가 11예(78.5%), persist 1예(7.2%) 있었다.(p=0.389). 수술 후 만족은 group 1이 17예(77.3%), group가 9예(64.2%)로 group 1이 group 2에 비해 만족도가 높았지만 통계적으로는 유의한 차이를 보이지 않았다(p=0.396). 보상성 다한증의 발생률은 group 1이 각각 21예(95.4%)로 group 2의 10예(71.4%)에 비해 보상성 다한증 발생률이 높았다(p=0.042). 보상성 다한증의 정도는 group 1에서 grade 1은 1예(4.5%), grade 2는 4예(18.2%), grade 3은 8예(36.4%), grade 4는 9예(40.1%)로 group 2에서 grade 1은 3예(21.4%), grade 2는 5예(35.7%), grade 3은 5예(35.7%), grade 4는 1예(7.2%)로 group 2에서 grade 3, 4의 보상성 다한증에 의해 생활의 불편함이 있는 환자가 적음을 알 수 있었다.(p=0.036). 제 2 흉부교감신경 클립 차단과 제 2 흉부교감신경 교통지 절제 후의 보상성 다한증 발생을 비교한 결과 교통가지 절제술에서 보상성 다한증 발생의 유의한 감소를 보여 보상성 다한증을 감소시키기 위해서는 교통가지 절제술이 우수함을 알 수 있었다.
