BACKGROUND: Da Vinci Surgical System is one of the greatest inventions of the 20th century, which represents the development direction of the precise minimally invasive surgical techniques, the aim of this study was to comparing the short-term outcomes between da Vinci robot-assisted lobectomy and video-assisted thoracic surgery (VATS) lobectomy for non-small cell lung cancer. METHODS: 45 pairs of non-small cell lung cancer patients underwent pulmonary lobectomy with da Vinci Robotic assisted thoracoscopic (RATS) and VATS approach during the same period from January 2014 to January 2017. The operative time, estimated blood loss (EBL), total number and total groups of dissected lymph nodes, postoperative duration of drainage, the first day volume of drainage, total volume of drainage were compared. RESULTS: No perioperative death and convertion to thoracotomy occured in both groups. There were significant difference between RATS group and VATS group in EBL [(50.30±32.33) mL vs (208.60±132.63) mL], the first day volume of drainage [(275.00±145.42) mL vs (347.60±125.80) mL], the dissected total number [(22.67±9.67) vs (15.51±5.41)] and total team [(6.31±1.43) vs (4.91±1.04)] of lymph node. There were no significant difference in other outcomes. CONCLUSIONS RATS is safe and effective and took better short-outcomes than VATS in non-small cell lung cancer.

Minimal invasive surgery with short operation time and enhanced recovery after surgery can truly achieve biological minimal invasiveness. The minimal invasive lung cancer surgery includes several kinds, such as uni-portal video-assisted thoracoscopic surgery (VATS) and multi-portal VATS. Robotic-assisted thoracic surgery (RATS) can be categorized into multi-portal VATS. As a frontier technology of minimal invasive surgical technique, surgical robotic system has been broadly applied in many areas. The average RATS operation time is (91.51±30.80) min among our team, which is much shorter than reported uni-portal VATS operation time. For now, RATS has some drawbacks and is lacking of national practice guidelines, which, we believe, will be solved by technology development and large-scale randomized controlled trials.

Chest wall defect may be caused by many factors such as the resection of tumor and trauma, and the reconstruction of bone-defection is still the key point of thoracic surgery. With the development of material science, more and more new materials have been used in medical practice, which makes huge progress in the surgery of chest wall. However, none of these materials satisfy all the practical needs of the reconstruction. Recently, with the development of the capacity of computer, 3D-printing technology has been gradually used in clinical work, and the idea of individual treatment has been accepted by more and more people. The weakness of these materials may be solved by the new material and the application of individual treatment, which could also make great advance in chest wall surgery. This article will make a summary of the research on the reconstruction of chest wall.

INTRODUCTIONThis study aimed to evaluate the clinical and radiological outcomes, and safety and efficacy of percutaneous pedicle screw fixation (PPSF) in the treatment of thoracolumbar burst fractures.

METHODSThis was a retrospective review of patients with thoracolumbar burst fractures treated with PPSF in a single hospital from 2010 to 2011. Baseline data included patient demographics, mechanism of injuries, fracture level, neurologic status and the number of percutaneous screws inserted. Kyphotic angle correction, vertebral body height restoration and mid-sagittal canal diameter improvement were used to assess radiological outcome. Screw misplacement, operative complications, functional improvement (ASIA score) and pain score on visual analogue scale were used to assess safety and clinical outcomes.

RESULTS21 patients with 25 thoracolumbar burst fractures were treated with 134 percutaneous screws. There was significant improvement in kyphotic angle correction (mean difference 6.1 degrees, p = 0.006), restoration of anterior and posterior vertebral height (mean difference 19.7%, p < 0.01 and mean difference 6.6%, p = 0.007, respectively) and mid-sagittal canal diameter (mean difference 15.6%, p = 0.007) on discharge. These improvements remained statistically significant at six months post operation for restoration of anterior vertebral body height (mean difference 9.8%, p = 0.05) and mid-sagittal diameter (mean difference 30.0%, p < 0.01).

CONCLUSIONIn this first local review, we have shown that PPSF is a relatively safe and effective technique for treating selected thoracolumbar burst fractures, and that it yields satisfactory results. However, its long-term outcome and efficacy need to be further evaluated.

OBJECTIVETo compare the differences in intrapulmonary shunt (Qs/Qt) and arterial oxygenation between selective left lower lobar blockade by Coopdech endobronchial blocker tubes (BB) and one lung ventilation (OLV) by left-sided double-lumen endobronchial tubes (DLT) in patients with normal pulmonary function.

METHODSThirty-six patients (aged 32-64 years) scheduled for lower esophageal surgery were allocated randomly into BB and DLT groups (n=18). Anesthesia was induced and maintained with Propofol by target controlled infusion with intravenous administration of sufentanil and cisatracurium if needed. A 35 to 39 French tube was placed in the DLT group, and an 8.0-mm (internal diameter) single-lumen endotracheal tube was used in the BB group where a 9 French Coopdech BB was advanced into the left lower lobar bronchus guided by a fiberoptic bronchoscope. The variables recorded were blood gas analysis data from the venous and arterial blood samples at 20 min after two-lung ventilation in supine position (T(1)), 20 min after initiation of one-lung ventilation or selective left lower lobar blockade by inflating BB balloons in the right lateral decubitus position (T(2)), total collapse of the left lung or the left lower lobe after the pleura was opened (T(3)), and before tracheal extubation (T(4)). Qs/Qt was calculated using a standard formula based on the three-compartment model. Upon pleura opening, the effectiveness of lung collapse was evaluated by the surgeon who performed the surgery. Chest radiograph and arterial blood gas analyses were performed the day after the operation.

RESULTSBoth of the groups were similar with regard to rank of the surgical exposure, pH, PaCO(2), hemoglobin from T(1) to T(4), Qs/Qt, PaO(2), PO(2), and oxygenation index at T1. In BB group, a significant reduction of Qs/Qt and greater improvements in PaO(2), PO(2), oxygenation index at T(2), T(3) and T(4) were observed in comparison with those in DLT group (P<0.05 or <0.01). No lobe collapse was observed postoperatively in BB group, but 2 patients in DLT group showed left lower lobe atelectasis. The patients in BB group showed better postoperative arterial oxygenation and shorter postoperative hospital stay (P<0.01).

CONCLUSIONSelective left lower lobar blockade by Coopdech endobronchial blocker tube during lower esophageal surgery provides a lower intraoperative intrapulmonary shunt and a better intra- and postoperative arterial oxygenation..

OBJECTIVE: To review the management of NUSS procedure by video-assisted thoracoscopy for the correction of pectus excavatum in 18 patients, and to prevent and treat some complications. METHODS: Eighteen patients with severe pectus excavatum underwent NUSS procedure by video-assisted thoracoscopy from December 2006 to September 2007. RESULTS: The operation time ranged from 30 to 70 min ( average 45 min). Good Results were achieved for all patients after the operation. All of them recovered and were discharged 5 approximately 7 days after the operation. Minor complications occurred in 2 patients. CONCLUSION NUSS procedure is microinvasive and has beautiful outlook with shorter operation time and simple handling.The minimally invasive technique has a low complication rate with satisfactory short-term result. Proper management is important for the recovery at the early postoperative stage.

OBJECTIVETo compare the precision of the vertebral screw insertion in treating idiopathic thoracic scoliosis by thoracoscopy with that by mini anterior thoracotomy.

METHODSTen patients with an average Cobb angle of 52.9 degrees were operated thoracoscopically (group A), and twenty-one patients with an average Cobb angle of 45.4 degrees were operated by mini anterior thoracotomy (group B). In order to determine the accuracy of screw placement, several parameters were measured postoperatively on each instrumented level of CT scan, including the entry point and entry direction of screw, the relationships between the screw tip and aorta as well as spinal canal. The safety of screw placement was determined at the position of screw to the vertebral canal and the aorta, and the results of CT analysis were designated as; D, the screw tip was distant from the aorta (> or = 1 mm); A, the screw tip was adjacent to the aorta (< 1 mm); C, the screw tip was felt to be against the aorta and creating contour deformity. The screw which had a bi-cortical purchase but was distant from the aorta and vertebral canal was defined as a satisfied screw.

RESULTS73 screws were inserted into patients of Group A, and 162 into patients in Group B. Parameters measured on CT image and X-ray showed no difference between these two groups (P > 0.05). There is no difference (P > 0.05) between A and B group of percentages in D (89.0% vs. 80.2%), in bi-cortical purchase (89.0% vs. 87.0%), and in satisfaction of screw placement (74.0% vs. 66.0%).

CONCLUSIONThoracoscopic and mini-open thoracotomic anterior correction are safe and effective to correct idiopathic right thoracic scoliosis with satisfied correction. Vertebral screws placed by both techniques have the same satisfied accuracy, safety, bi-cortical purchase and the satisfaction rate either in total screws or in the corresponding area.

We evaluated the safety and stability of the less-invasive submuscular bar fixation method in the Nuss procedure. One hundred and thirteen patients undergoing the Nuss procedure were divided into three groups according to the bar fixation technique employed. Group 1 consisted of 25 patients who had undergone bilateral pericostal bar fixation, group 2 consisted of 39 patients with unilateral pericostal one, and group 3 included 49 patients with bilateral submuscular one. The patients' age ranged from 2 to 25 yr, with an average of 7.2+/-5.67 yr. Bar dislocation occurred in 1 patient (4%) in Group 1, 2 patients (5.1%) in Group 2, and 1 patient (2.0%) in Group 3 (p=0.46). Hemothorax was noted in 2 patients (8%) in Group 1, 2 (5.1%) in Group 2, and none (0%) in Group 3 (Group 1 vs. Group 3, p=0.028). The mean operation time was shorter in Group 3 than Group 1 (50.1+/-21.00 in Group 3 vs. 67.2+/-33.07 min in Group 1, p=0.041). The submuscular bar fixation results in a decrease in technique-related complications and operation time and is associated with favorable results with regard to the prevention of bar dislodgement.
