Abstract Background Minimally invasive esophagectomy (MIE) is a complex operation, and the detailed optimal surgical procedure has not been well described. Our aim was to evaluate use of a simple method of laparoscopic gastric tube construction as minimally invasive surgery for patients with esophageal cancer. Methods We performed a retrospective review of 26 consecutive patients who underwent MIE for esophageal cancer in the Koo Foundation Sun Yat-Sen Cancer Center between September 2009 and August 2011. Perioperative data and postoperative complications were statistically analyzed. Results The patient group consisted of 22 men and 4 women. MIE was performed successfully in all patients. The mean operative time was 430.4 ± 60.6 minutes, and the mean estimated operative blood loss was 135.0 ± 97.8 mL. There were no cases of conversion to open surgery during the procedure. The postoperative complication rate was 53.8%, and there was no surgical mortality. Conclusions We recommend this novel method of total laparoscopic staplized formation of gastric tube to facilitate gastric pull-up.

Background: Single-port video-assisted thoracoscopic surgery (VATS) has attracted much attention recently; however, it is still very challenging to perform especially on more technically demanding sublobar anatomic resection procedures such as segmentectomy. Therefore we conducted a retrospective study on the perioperative results of single-port segmentectomy using a propensity-matched method for comparison with multi-port segmentectomy in patients with primary lung cancer., Methods: For procedures of anatomic segmentectomy performed between May 2006 and March 2014, we retrieved data on patients' demographic information, medical history, cancer information, and postoperative outcomes from our surgical database of thoracoscopic lung cancer surgery. Outcome variables included the number of lymph nodes retrieved during the surgery, the amount of blood loss, the duration of hospitalization, the length of the wound, the operation duration in minutes, and incidence and types of complication. The t-test and Chi-squared test were used to compare demographic and clinical variables between single- and multi-port approaches., Results: A total of 98 consecutive patients who underwent VATS segmentectomy for lung cancer treatment were identified in our database: 52 (53.1%) underwent a single-port segmentectomy and 46 (46.9%) had a multi-port segmentectomy. After propensity score matching, the differences in patients' age, pulmonary function tests, tumor size, and operating surgeons were no longer significant between the two sample groups. The length of the wound was the only surgical outcome for which single-port segmentectomy had a significantly better outcome than multi-port segmentectomy (P value <0.001)., Conclusions: This study showed that single-port VATS segmentectomy yielded comparable surgical outcomes to multi-port segmentectomy despite technique difficulties and smaller wound in our setting.

Objectives: The feasibility and radicalism of lymph node dissection for lung cancer surgery by a single-port technique has frequently been challenged. We performed a retrospective cohort study to investigate this issue., Methods: Two chest surgeons initiated multiple-port thoracoscopic surgery in a 180-bed cancer centre in 2005 and shifted to a single-port technique gradually after 2010. Data, including demographic and clinical information, from 389 patients receiving multiport thoracoscopic lobectomy or segmentectomy and 149 consecutive patients undergoing either single-port lobectomy or segmentectomy for primary non-small-cell lung cancer were retrieved and entered for statistical analysis by multivariable linear regression models and Box-Cox transformed multivariable analysis., Results: The mean number of total dissected lymph nodes in the lobectomy group was 28.5 ± 11.7 for the single-port group versus 25.2 ± 11.3 for the multiport group; the mean number of total dissected lymph nodes in the segmentectomy group was 19.5 ± 10.8 for the single-port group versus 17.9 ± 10.3 for the multiport group. In linear multivariable and after Box-Cox transformed multivariable analyses, the single-port approach was still associated with a higher total number of dissected lymph nodes., Conclusions: The total number of dissected lymph nodes for primary lung cancer surgery by single-port video-assisted thoracoscopic surgery (VATS) was higher than by multiport VATS in univariable, multivariable linear regression and Box-Cox transformed multivariable analyses. This study confirmed that highly effective lymph node dissection could be achieved through single-port VATS in our setting., (© The Author 2015.

Background: Thoracoscopic lobectomy and segmentectomy have been demonstrated to be safe and technically feasible for curative resection of lung cancer. This minimally invasive surgery is increasingly popular and adopted by the world all over. We report our short-term results of thoracoscopic lobectomy/segmentectomy operations comparing with previous surgical approach for lung cancer resection by muscle-sparing vertical minithoracotomy in Koo Foundation Sun Yat-Sen Cancer Center., Methods: We performed a retrospective review of 317 consecutive patients who underwent lobectomy or segmentectomy either by thoracoscopic surgery (n=121) or muscle-sparing vertical mini-thoracotomy (n=195) for lung cancer in Koo Foundation Sun Yat-Sen Cancer center between Jan 2000 and Jun 2009. The operative details, postoperative complication, and length of stay were statistically analyzed., Results: Thoracoscopic lobectomy and segmentectomy were performed successfully in 121 patients. One patient was converted to open thoracotomy during operation due to uncontrolled bleeding. There is no significant difference in age factors (p=0.763), forced expiratory volume in one second (p=0.480) or comorbidities (p=0.549) between these two groups. Thoracoscopic group had a significantly predominant percentage in women, diabetes mellitus, less smoking index and chronic obstructive pulmonary disease incidence. Patients undergoing a thoracoscopic surgery had a shorter length of stay (6.8±3.4 vs. 10.2±9.1 days, p<0.001), longer operative time (3.6±1.0 vs. 3.2±1.2 hours, p=0.004), and less blood loss (102.7±95.7 vs. 140.1±171.2 ml, p<0.029). There was no significant difference in postoperative complication rate between the two groups (18.2% vs. 23.6%, p=0.255). No surgical mortality was found in the thoracoscopic group., Conclusions: Our findings suggested thoracoscopic surgery for lung cancer would be as safe as muscle-sparing vertical mini-thoracotomy in lobectomy and segmentectomy.
