Uniportal complete video-assisted thoracoscopic lobectomy with systematic lymphadenectomy

Uniportal versus three-port video-assisted thoracoscopic surgery for non-small cell lung cancer: A retrospective study

BACKGROUND

To investigate the uniportal video-assisted thoracoscopic surgery (VATS) technique and safety of non-small cell lung cancer (NSCLC) patients treated with uniportal and three-port VATS.

METHODS

We retrospectively evaluated 146 consecutive patients with NSCLC who underwent VATS lobectomy between January 2018 and May 2018. The general clinical date, perioperative data and life quality were individually compared and analyzed between the two groups.

RESULTS

Intraoperative blood loss was significantly lower in the uniportal than in the three-port group (p = 0.035), and significantly shorter chest tube drainage and postoperative hospital stay durations were found in the uniportal than in the three-port group (p = 0.022 and p = 0.008). The postoperative 24 and 72 h numerical rating scale (NRS) scores were significantly lower in the uniportal group than in the three-port group (p < 0.001 and p < 0.001). There were no significant differences between the two groups in the number or stations of total lymph node dissected (p = 0.222 and p = 0.159). There were no significant differences between the two groups in the postoperative total or respiratory complications (p = 0.917 and p = 0.930).

CONCLUSIONS

Uniportal VATS is a safe and effective alternative for patients with NSCLC. It is a preferable option for appropriate cases as it is conducive to patients' postoperative recovery and quality of life.

Clock dial integrated positioning combined with single utility port video-assisted thoracoscopic surgery: a new localization method for lung tumors

Background

Preoperative localization of lung tumor mainly consisted of two methods: CT-guided percutaneous localization and electromagnetic navigation bronchoscopy-guided localization. However, these invasive methods could result in serious complications. In order to avoid the adverse effects of preoperative invasive localization, we propose a method of intraoperative noninvasive localization for lung tumors: clock dial integrated positioning (CDIP).

Methods

To retrospectively analyze the clinic data about the application of CDIP for 127 lung tumour patients in single utility port video-assisted thoracoscopic surgery (SUPVATS) between June 2017 and October 2017.

Results

One hundred and twenty-four cases (97.64%) underwent thoracoscopic surgery, which including 14 lobectomy, 107 partial resection, 2 lobectomy plus partial resection and 1 left pneumonectomy. Three cases (2.36%) underwent thoracoscopic biopsy. The mean operation time and intraoperative bleeding were 47.9±22.1 min and 70.1±40.3 mL, respectively. The mean postoperative hospital stay and chest drain duration were 3.9±2.2 and 3.6±1.8 days, respectively. There were 118 cases of malignant tumors, including adenocarcinoma (n=101), squamous cell carcinoma (n=9), large cell carcinoma (n=2), small cell lung carcinoma (n=3), and metastatic lung carcinoma (n=3). The remaining nine cases were benign tumors, including granuloma (n=3), intrapulmonary lymph node (n=2), sclerosing hemangioma (n=2), and hamartoma (n=2). The incidence of postoperative complications was 10.2%. There was no mortality, secondary operation, or conversion to open procedure due to massive intraoperative bleeding.

Conclusions

CDIP combined with SUPVATS is a safe, feasible, and effective method for the localization of lung tumors. This novel method can provide a reliable alternative technique when the marker is dislocated.

[Short-term Outcome of Uniportal and Three Portal Video-assisted Thoracic Surgery for Patients with Non-small Cell Lung Cancer]

BACKGROUND

Currently, there are many reports on the advantages of three portal video-assisted thoracic surgery (VATS) in the treatment of lung cancer, but there are few reports on the comparison between uniportal and three portal video-assisted thoracic surgery. In this study, we aimed to evaluate the recent curative effect of the postoperative short-term quality of life between uniportal and three portal video-assisted thoracic surgery for non-small cell lung cancer.

METHODS

We retrospectively evaluated 266 patients with NSCLC who underwent intended VATS lobectomy by a single surgical team in our ward between January 2016 and August 2017. The general clinical date, perioperative data and short-term life quality were individually compared and analyzed between the two groups.

RESULTS

The two groups were similar in terms of clinicopathological features, total number of dissected lymph nodes and nodal stations, postoperative complications and pulmonary complications (P>0.05). Compared with three portal VATS, the intraoperative blood loss, chest tube duration, postoperative thoracic drainage, length of stay and NRS score were significantly decreased in uniportal VATS, with significant differences (P<0.05).

CONCLUSIONS

As a more minimally invasive surgery, uniportal VATS can be safely and effectively performed for resectable lung cancer, which would achieve even better operation curative effect than three portal VATS.

Uniportal video-assisted thoracoscopic anatomic segmentectomy for small-sized lung cancer

Increasing evidences prove video-assisted thoracic surgery (VATS) segmentectomy is accepted as a valid alternative to lobectomy esp. a greater number of small lung nodules have been detected. Uniportal VATS segmentectomy for small-sized lung cancer is more challenging not only for technical issues in simple or complex uniportal segmentectomy, but also considering oncological efficacy in terms of localization, safe margin, the extent of lymph node dissection and pathological analysis. In this work, we evaluated our evolving uniportal experience, the surgical technique and decision-making of uniportal VATS segmentectomy for small-sized lung cancer.

Advantages and disadvantages of single incision VATS in major anatomical resection for lung cancer

Safety and feasibility of lung resections by single incision thoracoscopy have been confirmed in large number of studies. As proponents claim its lesser invasive nature caused by lacking of additional intercostal port(s), opponents question the outcome measures of the approach especially in oncological manner. Since there is no major discussion regarding the superiority of video-assisted thoracoscopic surgery (VATS) on lung resections over the open technique in the surgical management of lung cancer today, advantage and disadvantage of single incision VATS lung resections was reviewed with the comparison of standard, multi-port VATS approach in this article. Overall, results of comparative studies confirm that single incision and multiportal thoracoscopy are similar, or single incision thoracoscopy has more advantages in the lung resection for lung cancer. Currently, the main disadvantage of single incision approach is the lacking of long-term oncological results.

Uniportal complete video-assisted thoracoscopic surgery lobectomy with partial pulmonary arterioplasty for lung cancer with calcified lymph node

Now, more and more complete video-assisted thoracoscopic surgery (cVATS) surgeons are capable of performing lobectomy by uniportal approach. However, concerns regarding the safety of uniportal procedures for complex cases such as neoadjuvant chemotherapy, bronchial sleeves or vascular reconstructions still remains. As experience with uniportal VATS has increased, its application toward more technically demanding operations has also expanded. This article describes a uniportal cVATS left upper lobectomy with partial pulmonary arterioplasty for lung cancer with calcified lymph nodes. In order to reduce the risk of bleeding, we looped the left main pulmonary artery and applied two-stage maneuvering for left upper lobe (LUL) bronchus, cut the bronchus at the distal end and close the stump using a stapler at the end, which are conducive to maximal safety.
