ObjectiveTo explore clinical outcomes of video-assisted thoracoscopic sympathectomy (VATS) for the treatment of palmar hyperhidrosis (PH), and compare the results between T2 segment surgery and T2-T3 segment surgery. MethodsFrom April 2009 to August 2012, 48 consecutive PH patients underwent single-port VATS in Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University. There were 18 male and 30 female patients with their age of 14-40 (22.1±5.4) years. According to different surgical procedures, all the patients were divided into T2 segment group (29 patients) and T2-T3 segment group (19 patients). Preoperative characteristics, surgical results and postoperative morbidity were compared between the 2 groups. ResultsPH symptoms disappeared after VATS in all the patients. Patients were followed up for 6-44(21.3±10.1)months, and 2 patients were lost in both T2 segment group and T2-T3 segment group. The incidence of postoperative compensatory sweating was 66.7% (18/29) in T2 segment group and 70.6% (12/19) in T2-T3 segment group. The incidence of moderate to severe compensatory sweating of T2 segment group was significantly higher than that of T2-T3 segment group (51.9% vs. 29.4%, P < 0.05). Twenty-six patients (96.3%) in T2 segment group and 16 patients (94.1%) in T2-T3 segment group were completely or partially satisfied with surgical results. ConclusionVATS is the only effective surgical procedure for the treatment of moderate to severe PH. Both T2 and T2-T3 segment sympathectomy can effectively reduce PH symptoms after VATS, but the incidence of postoperative compensatory sweating is high, which has negative influence on patients'satisfaction.
ObjectiveTo compare effectiveness and safety of video-assisted thoracic surgery (VATS) and thoracotomy in lymph node (LN) dissection for lung cancer. MethodsA comprehensive search of PubMed, Ovid Medline, EMbase, Web of Science, ScienceDirect, the Cochrane Library, Scopus and Google Scholar was performed to identify studies (from January 1990 to July 2015) comparing VATS with thoracotomy in LN dissection. The data were analyzed by RevMan 5.3 software. Quality of literature was evaluated by Newcastle-Ottawa scale or Jadad scale. ResultsFifty-one articles met the inclusion criteria involved 7 127 patients in the VATS group and 9 217 patients in the thoracotomy group. Thirty-eight articles were of good quality and the remaining thirteen were medium. Meta-analysis showed that fewer N1 LN stations in the VATS group (95% CI -0.23 to -0.04, P=0.005), although VATS harvested more left-side LNs (95% CI 0.51 to 3.22, P=0.007). The number of total LNs (95% CI -1.81 to 0.28, P=0.15), total LN stations (95% CI -0.34 to 0.15, P=0.44), N2 LNs (95%CI -1.77 to 0.79, P=0.45), N2 LN stations (95% CI -0.22 to 0.16, P=0.78), N1 LNs (95% CI -0.95 to 0.11, P=0.12), and right-side LNs (95% CI -1.52 to 2.23, P=0.71) harvested in the two groups were not significantly different. ConclusionIn the surgical treatment of lung cancer, VATS can achieve the same efficacy of LN dissection as thoracotomy. This conclusion still needs to be further proved by more high-quality and large-scale RCTs.
