Factors Affecting the Number of Stapler Cartridges in Complete Video-Assisted Thoracoscopic Surgery Lobectomy for Non-small Cell Lung Cancer.

BackgroundVideo-assisted thoracoscopic surgery (VATS) lobectomy has become the major surgical option for the treatment of non-small cell lung cancer (NSCLC). Endoscopic instruments such as stapler cartridges are essential for VATS procedures. In this study, we investigated the factors that affect the number of stapler cartridges used in VATS lobectomy.MethodsA retrospective analysis was conducted of patients who underwent complete VATS lobectomy for NSCLC from January 2013 to December 2015.ResultsIn total, 596 patients underwent complete VATS lobectomy. The average number of stapler cartridges used for VATS lobectomy was 5.3±1.9. The number of stapler cartridges used for VATS lobectomy was higher in men (5.5±1.9 vs. 5.0±18, p=0.006), those aged older than 70 years (5.5±2.1 vs. 5.1±1.7, p=0.038), those who underwent upper or middle lobectomy procedures (5.7±1.9 vs. 4.1±1.2, p<0.001), those with a higher fissure sum average (p<0.001), and those in whom surgery was performed by a surgeon with a preference for staplers (5.6±2.0 vs. 4.9±1.6, p<0.001).ConclusionThe number of stapler cartridges required to perform VATS lobectomy in NSCLC patients appears to be influenced by sex, age, the location of the tumor, the degree of fissure development, and the surgeon’s preference.

Efficacy of complete video-assisted thoracoscopic surgery lobectomy using the three-dimensional endoscopic system for lung cancer.

We aimed to investigate the efficacy of complete video-assisted thoracoscopic surgery (cVATS) lobectomy using the three-dimensional (3D) endoscopic system in patients with lung cancer and compare it with that of cVATS lobectomy using the conventional two-dimensional (2D) endoscopic system in former consecutive cases. We retrospectively analyzed the prospectively collected database of patients with clinical stage I lung cancer who underwent cVATS lobectomy using the 3D endoscopic system; the patients who underwent surgery using the 2D endoscopic system were considered the historical control group. The operative and perioperative data were compared, and propensity-score matched comparisons were used to assess the potential impact of selection bias. We performed 189 cVATS lobectomies. Of these, 105 were performed using the 3D endoscopic system, while 84 were performed using the 2D endoscopic system. After matching, there was no significant difference in the preoperative factors between the two groups. The operation time was significantly shortened (P = 0.003), and the intraoperative blood loss was significantly reduced in the 3D group (P < 0.001). In particular, there was only one case of intraoperative hemorrhage of 201mL or more in the 3D group, compared to 12 cases in the 2D group (P < 0.001). After matching, the intraoperative blood loss and operation time were significantly reduced in the 3D group. Our results showed that the 3D endoscopic system for cVATS lobectomy may be a useful surgical tool and switching to it from the 2D endoscopic system can be performed safely.

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.

A Study of Complete Video-Assisted Thoracoscopic Surgery Lobectomy in Treatment of Elderly Patients with Non-Small Cell Lung Cancer: Curative Effect and Impact on Clinical Prognosis.

The present study intends to investigate the clinical value of complete video-assisted thoracoscopic surgery (c-VATS) lobectomy in treatment of elderly patients with non-small cell lung cancer (NSCLC). A total of 100 cases of elderly patients with NSCLC admitted in our hospital from March 2012 to March 2014 were enrolled in this study and divided into the research group (n=50) and control group (n=50) by random sampling method. All patients in the research group underwent c-VATS lobectomy, while those in the control group underwent conventional lobectomy via thoracotomy. The duration of operation, length of incision, intraoperative blood loss, indwelling time of drainage tube, postoperative complication rate, the number of excised lymph nodes, the time of removing stitches, mean length of stay, and vision analog score (VAS) in two groups were observed and compared. The pulmonary function and arterial blood gas before surgery and six months after surgery in two groups were detected and compared. A regular follow-up study was conducted after surgery. The one-year survival rate in two groups were calculated and compared. The differences in the duration of operation, length of incision, indwelling time of drainage tube, postoperative complication rate, the time of removing stitches, mean length of stay, and VAS score between two groups were statistically significant (all P<0.05). The postoperative vital capacity, forced vital capacity (FVC), forced expiratory volume in 1s (FEV1), FEV1 to FVC ratio, 25 and 75% of forced expiratory flow, and the degree of decline in maximum ventilatory volume per minute compared to that before surgery in c-VATS group were significantly less than those in conventional thoracotomy group (all P<0.05). The degree of advance in postoperative partial pressure of arterial oxygen and saturation of arterial oxygen compared to those before surgery, and the degree of decline in partial pressure of arterial carbon dioxide compared to that before surgery were significantly greater than those in conventional thoracotomy group (all P<0.05). The differences in intraoperative blood loss, the number of excised lymph nodes, and one-year survival rate were not statistically significant (all P>0.05). VATS lobectomy has advantages of smaller incision in treatment of NSCLC, faster recovery, and better prognosis compared to traditional therapy.

Nursing for the complete VATS lobectomy performed with non-tracheal intubation.

Video-assisted thoracoscopic surgery (VATS) has without doubt been the most important advance in thoracic surgery. The general anesthesia before the tracheal intubation for VATS was often accompanied with tracheal mucosa and lung injuries, which were typically manifested as painful throat, nausea, vomiting, and other symptoms. However, the non-intubated anesthesia VATS can avoid these shortcomings due to its shorter anesthesia time, simpler steps, and quicker post-operative recovery. A total of 63 patients underwent VATS lobectomy under non-intubated anesthesia from July 2012 to July 2013. Good teamwork, proper pre-operative visit, and comfortable intra-operative position had ensured the success of these operations. In conclusion, adequate pre-operative preparation, careful nursing, and close cooperation can achieve a successful non-intubated anesthesia VATS.

Robot-assisted lobectomy for non-small cell lung cancer in china: initial experience and techniques.

To summarize our initial experience in robot-assisted thoracoscopic lobectomy. Methods Five patients underwent lobectomy using da Vinci S HD Surgical System (Intuitive Surgical, Sunnyvale, California). During the operation, we respectively made four ports over chest wall for positioning robotic endoscope, left and right robotic arms and auxiliary instruments without retracting ribs. The procedure followed sequential anatomy as complete video-assisted thoracoscopic surgery lobectomy did, and lymph node dissection followed international standard. All patients successfully underwent complete robot-assisted thoracoscopic lobectomy. Neither additional incisions nor emergent conversion to a thoracotomy happened. Frozen dissection during lobectomy showed non-small-cell lung cancer in four patients, who afterwards underwent systemic lymph node dissection, while the case left was with tuberculoma and didn't undergo lymph node dissection. Recurrent air leak occurred in one case, so chest tube was kept for drainage, and one week later, the patient was extubated due to improvement. All other patients recovered well postoperatively without obvious postoperative complications. Robot-assisted thoracoscopic surgery is feasible with good operability, clear visual field, reliable action and its supriority of trouble free; exquisite operative skills are required to ensure a stable and safe operation; robot-assisted surgery is efficiency and patients recover well postoperatively.

Complete video-assisted thoracoscopic surgery lobectomy and its learning curve. A single center study introducing the technique in The Netherlands

Data regarding the benefits for the complete video-assisted thoracic surgery (c-VATS) lobectomy over the open lobectomy are numerous. This article describes the experience of introducing this technique in a training hospital, the first reported cohort in The Netherlands. From March 2006 to November 2008, all patients operated on for proven or suspected lung cancer were analyzed. Prospective data from these patients were evaluated. A subgroup analysis for the c-VATS lobectomy is presented. A total of 184 operations were performed on 172 patients. In 122 (66.3%) of the operations the resection ended in a lobectomy of which 70 were done by complete thoracoscopic procedure. For the c-VATS lobectomy the mean operating time was 179 min, with a mean blood loss of 444 ml. The median hospital stay was four days. Complications were present in 10% of c-VATS lobectomies. No mortality was seen in the c-VATS group. After thorough evaluation and training, c-VATS lobectomy is a safe procedure that can be performed in a relatively low volume hospital. It has exceptional short-term benefits. For training purposes all operations must start thoracoscopically. All patients must be operated according the intention to treat method.

Complete versus assisted thoracoscopic approach: a prospective randomized trial comparing a variety of video-assisted thoracoscopic lobectomy techniques

Video-assisted thoracoscopic surgery (VATS) lobectomy does not represent a unified approach, but rather a spectrum of operative techniques ranging from a complete endoscopic thoracotomy to a minithoracotomy. A prospective randomized trial was conducted to compare the differences in these techniques and their results to determine the best of VATS lobectomy for lung cancer. This study randomized 39 consecutive patients with clinical stage I lung cancer to undergo either a complete (C-VATS, n = 20) or an assisted (A-VATS, n = 19) VATS approach for pulmonary lobectomy. The operating time was longer (p = 0.002) and blood loss was less (p = 0.004) with C-VATS than with A-VATS. Although there was no significant difference in analgesic use or duration of thoracic drainage between the groups, a shorter hospitalization was observed after C-VATS. Serum peak levels of postoperative inflammatory markers (white blood cell count, C-reactive protein, creatine phosphokinase) were lower with C-VATS and an earlier return to normalization than with A-VATS. Various differences exist among the VATS lobectomy techniques, and complete VATS lobectomy as a purely endoscopic surgery may be technically feasible and a satisfactory alternative to the conventional procedure for stage I lung cancer.
