ABSTRACT
Objective To compare the efficacy of uniportal VATS and single utility port VATS in treatment of spontaneous pneumothorax.Method From January 2013 to December 2015, we retrospectively collected clinical data of 53 patients with spontaneous pneumothorax who were treated with uniportal VATS, as study group; compared with control group: 53 patients received single utility port VATS in the same period. The clinical data was compared between the two groups, including the operation time, intraoperative blood loss, drainage time, postoperative extubation time, postoperative pain score, postoperative hospitalization and recurrence.Results All patients were successfully completed the operation, no death and serious complications occurred. There were no significant differences in intraoperative blood lose, duration of chest drainage, duration of hospital stay and incidence of serious postoperative complications between two groups (P > 0.05). Mean Visual Analogic Scale (VAS) score for 24 h post-operative pain was: (2.60 ± 0.71) for uniportal VATS and (3.38 ± 0.84) for single utility port VATS (P > 0.05), 72 h post-operative pain was: (1.30 ± 0.51) for uniportal VATS and (1.58 ± 0.62) for single utility port VATS (P > 0.05). Follow up 5 ~ 36 months, median follow up was 19 months. No recurrence occurred during follow up.Conclusions The study suggested that both surgical approaches to spontaneous pneumothorax are safe and effective. Significant differences were found for early post-operative pain between the two approaches, the uniportal way is better. It is worthy of clinical promoting.
ABSTRACT
Objective To investigate curative effects and prognostic factors of video-assisted thoracoscopic extended thymectomy ( VATET ) for nonthymomatous myasthenia gravis ( NTMG ) . Methods Clinical records of 43 patients with an established diagnosis of NTMG who underwent VATET from December 2009 to September 2014 were reviewed. Three-port thoracoscopic right thymectomy with resection of fat tissue in anterior mediastinum was conducted.The curative effects and prognostic factors were evaluated and analyzed with the Monden standard. Results The VATET was successfully completed in all the 43 patients.The operation time was 75-240 min (mean, 115.4 min).The intraoperative blood loss was 10-200 ml (mean, 42.2 ml). No peri-operative death occurred.Follow-ups for 4 -60 months ( mean, 36.2 months) showed 12 cases of remission, 18 cases of improvement, 10 cases of unchanged disease, and 3 cases of deterioration.The effective rate was 69.8% (30/43).Multivariate logistic regression analysis showed that pathological type of thymic hyperplasia was the independent risk factor for NTMG postoperative outcomes (β=0.921,95%CI:1.866-2.811, P=0.000). Conclusion Video-assisted thoracoscopic extended thymectomy is effective in most myasthenia gravis patients.
