Objective To explore clinical efficacy and independent risk factors related to the recurrence of primary spontaneous pneumothorax (PSP) after video-assisted thoracoscopic surgery (VATS). Method We retrospectively anal- yzed the clinical data of 566 PSP patients by VATS in our hospital between December 2011 and June 2014 year. The patients were divided into a triple-port group(110 patients with 88 males and 22 females, aged 31.34±15.62 years) and a double-port group (456 patients with 383 males and 73 females, aged 31.46±15.65 years) by operation methods. We tried to find out the independent risk factors related to the recurrence. Results There was no statistical difference in intraoperative blood loss, postoperative drainage, drain removal, postoperative complications, postoperative length of hospital stay and rate of postoperative recurrence between the two groups (P>0.05) . However, the operation time (P<0.001) and the drainage of postoperative 48 hours (P<0.05) in the double-port group was shorter or less than that in the triple-port group. The overall recurrence rate was 1.41% (8/566) . The minors (OR=14.75, P=0.045) , no bulla type (OR=32.76, P=0.019) , and multiple bulla type (OR=15.48, P=0.013) were the independent risk factors for postoperative recurrence. Conclusions The double- port VATS technique has similar effect with triple-port VATS technique on spontaneous pneumothorax patients under- gone pulmonary bullae ligation and pleurodesis. Bulla ligation and whole mechanical pleurodesis can get better clinical efficacy and lower rate of recurrence. The minor, no bulla type, and multiple bulla type are the independent recurrence risk factors of PSP after surgery.
ObjectiveTo compare and analyze clinical effects of video-assisted thoracoscopic surgery (VATS) lobectomy and systematic lymph node harvests for peripheral non-small cell lung cancer (PNSCLC) patients between single-port (SP) and multi-port (MP) with a propensity-matched analysis. MethodsWe retrospectively analyzed the clinical data of 324 patients presented with PNSCLC and admitted in the Affiliated Hospital of Qingdao University from January 2013 through December 2015. Six-eight patients underwent single-port thoracoscopic lobectomy were as a SP group and 256 patients with multi-port thoracoscopic lobectomy. Another 68 patients were produced by a propensity-matched analysis in these 256 patients, to match with SP group as a MP group. There were 26 males and 42 females at age of 54-62 (59.3±10.3) years in the SP group. There were 32 males and 36 females at age of 50-66 (61.5±9.4) years in the MP group. Perioperative outcomes were compared between the two groups. ResultsAll operations were accomplished successfully, without conversion to thoracotomy. Most postoperative outcomes were similar in intraoperative blood loss (136.3±22.7 ml vs. 142.2±20.3 ml), conversion (4.4% vs. 7.4%), lymph node dissection number (19.9±3.5 vs. 20.0±3.0), station (7.9±2.3 vs. 8.3±2.1), postoperative drainage volume (761.4±182.3 ml vs. 736.9±176.4 ml), chest drainage duration (5.2±1.5 d vs. 5.8±1.8 d), length of hospital stay (5.5±2.0 d vs. 5.0±2.5 d), and postoperative complications (2.9% vs. 7.4%) between the two groups (P > 0.05). There were statistical differences in operation time (138.2±20.3 min vs. 126.4±22.4 min), downtrend of pain scores (P=0.03), and patients' satisfaction level (8.8±1.4 vs. 7.3±2.3, P < 0.05). Concision Single-port thoracoscopic lobectomy is not inferior to multi-port and is a safe and feasible surgical procedure for the management of PNSCLC.
