  • long term assessment of percutaneous stereotactic Thermocoagulation of upper thoracic ganglionectomy and sympathectomy for palmar and craniofacial hyperhidrosis in 1742 cases
    Neurosurgery, 2002
    Co-Authors: Kingshun Chuang, Jiangchuan Liu
    Abstract:

    OBJECTIVE: We sought to determine the long-term outcome of percutaneous stereotactic Thermocoagulation for upper thorac ganglionectomy and sympathectomy in patients with palmar and craniofacial hyperhidrosis with the use or a three-dimensional system of coordinates for the location of the T2 and T3 ganglia on the basis of the findings in a cadaveric study. METHODS: From November 1986 to May 1998, upper thoracic ganglionectomy and sympathectomy with the use of percutaneous stereotactic Thermocoagulation were performed in 1688 patients with palmar hyperhidrosis and 54 patients with craniofacial hyperhidrosis as outpatient surgical procedures based on a three-dimensional coordinate system for determining the location of the Thermocoagulation point which was developed by the authors in a cadaveric study. The technique requires only local anesthesia. RESULTS: After initial Thermocoagulation, sweating stopped in 3465 (99.5%) of 3484 sides. Hyperhidrosis recurred within 2 to 59 months of treatment in 268 procedures. All patients in whom hyperhidrosis recurred were retreated successfully, resulting in a final success rate of 99.9%. Complications of treatment included pneumothorax in seven procedures (0.2%) and partial Horner's syndrome in five procedures (0.15%). Decreased plantar sweating was noted during follow-up in 92% of patients. CONCLUSION: The results of this study indicate that upper thoracic ganglionectomy and sympathectomy performed with the use of percutaneous Thermocoagulation are a very effective treatment for palmar and craniofacial hyperhidrosis that provides excellent immediate and long-term results as well as a low complication rate. The method is also effective as a retreatment for recurrences. Our data also suggest that performing ganglionectomy and sympathectomy in both T2 and T3 is unnecessary, because the procedure had equal long-term effectiveness when performed in T2 alone.

  • Thermocoagulation versus cryotherapy for the treatment of cervical precancers
    Journal of Obstetrics and Gynaecology Research, 2020
    Co-Authors: Lyufang Duan, Jerome L Belinson, Zhihong Liu, Aimin Xiao, Shuangyan Liu, Liwei Zhao, Chun Wang
    Abstract:

    AIM To compare Thermocoagulation and cryotherapy for treatment of high-grade cervical intraepithelial neoplasia (CIN). METHODS From May 2017 to May 2018, women with CIN2/3 were randomized to Thermocoagulation or cryotherapy at Peking University Shenzhen Hospital. Follow-up at 4 and 8 months included cytology and human papillomavirus (HPV) testing. Women who were HPV-positive or had atypical squamous cells of undetermined significance or higher-grade disease underwent colposcopy/biopsy. RESULTS Among 149 women enrolled, 74 were randomized to Thermocoagulation, and 75 to cryotherapy (excluded four were immediately referred for Thermocoagulation due to large lesions). At follow-up, there was no difference between the Thermocoagulation and cryotherapy groups in HPV-negative (4/8 months: 72.5%/86.2% vs 68.6%/80.6%) and pathology-negative (97.1%/98.5% vs 94.3%/92.3%) rates (all P > 0.05). The cytology-negative rate was similar for Thermocoagulation and cryotherapy at 4 months (79.7% vs 78.9%, P > 0.05), but higher for Thermocoagulation at 8 months (100% vs 88.7%, P < 0.05). No lesions were observed among the four referral women at follow-up. As compared with cryotherapy, Thermocoagulation was associated with shorter duration of treatment and less vaginal discharge, but higher pain during application and longer bleeding after treatment. CONCLUSION Thermocoagulation was as effective and safe as cryotherapy and might be easily applied to treat high-grade cervical lesions.
