ABSTRACT
BACKGROUND@#Thoracoscopic lobectomy combined with mediastinal lymph node dissection has been considered as one of the standard surgical procedures for early lung cancer. After 20 years of development, thoracoscopic lobectomy has reached a consensus on reliability and minimally invasive. At present, thoracoscopic lobectomy has a variety of incisions, which gradually evolve into four holes based on three holes, and two or one hole as the operative approach. The aim of this study was to evaluate the clinical value of four-hole unilateral dissecting lobectomy and mediastinal lymph node dissection in the treatment of non-small cell lung cancer (NSCLC). The aim of this study was to investigate the clinical value of anatomical lobectomy with mediastinal lymphadenectomy under four-hole completely video-assisted thoracoscopic surgery (C-VATS) in the treatment of non-small cell lung cancer.@*METHODS@#The patients undergoing lobectomy with mediastinal lymphadenectomy for NSCLC were identified in the Department of Thoracic Surgery, Yangzhou First People's Hospital, Yangzhou University from March 2015 to July 2016. Preoperative clinical diagnosis of peripheral-type early NSCLC. The patients were randomly divided into four-hole monophasic group (experimental group) and three-hole group (control group) according to the number of hospitalization before surgery. According to inclusion and exclusion criteria, the 39 cases assign in experimental group and 34 cases in the control group, including 36 males and 37 females; aged 38 to 84 years. The mean operation time, average blood loss, lymph node dissection group, average drainage, average extubation time and postoperative complications were compared between the two groups for statistical analysis.@*RESULTS@#The two groups of patients were successfully completed surgery, no death after surgery. Mean bleeding in the two groups, the number of lymph node dissection group, the average postoperative drainage, the average time of extubation, postoperative complications, with no significant difference. The average operation time of the four-hole unidirectional group was shorter than that of the three-hole group. The difference was statistically significant (P<0.05).@*CONCLUSIONS@#The safety and efficacy of a four-hole one-way operation under VATS are satisfactory. The operation is smooth during operation, which shortens the course of operation and deserves the clinical promotion. .

Objective To discuss if the intraoperative releasing inferior pulmonary ligament would affect the postoperative compensatory dilation of the residual lung in the patients going through the resection of the upper lobe under the thoracoscope. MethodFrom January 2010 to June 2014, 100 patients with lung cancer of right upper lobe were undergone resection of the upper lobe under thoracoscope in our department. They were randomly divided into two groups, the experimental group(the non-released group) with 50 people who were not released inferior pulmonary ligament during resection of the right upper lobe under thoracoscope. The control group(the released group) with 50 people who were released inferior pulmonary ligament during resection of the right upper lobe under thoracoscope. Observed the amount of daily thoracic cavity drainage, total drainage, the average extubation time and length of stay after the operation. Results Statistically compare postoperative residual cavity fluid level reserved rate of two groups of patients.There does not exist significant difference (P > 0.05) and the average drainage on the chest also is not significant (P > 0.05). Besides, there does not exist significant difference (P > 0.05) in the average time of decannulation of chest drainage tube, pleural biopsy cases and times, and postoperative hospital stay between two groups either. ConclusionIt’s unnecessary to release the inferior pulmonary ligament during resection of the right upper lobe under thoracoscope, which will not affect postoperative recovery and prolong length of hospital stay. Therefore it’s suitable for clinical promotion.
ABSTRACT
Objective To evaluate the clinical significance of dissection of pulmonary ligament was operated on videoassisted thoracic surgery(VATS) with bullectomy for spontaneous pneumothorax.Methods From Jan 2012 to Dec 2013, 232 patients (188 males, 44 females) underwent VATS with bullectomy for spontaneous pneumothorax or hemopeumothorax, whose age were between 14 and 45 years and mean age was(26.4 ± 10.1) years.202 patients resulted from upper lobe spontaneous pneumothorax, 23 patients for lower lobe spontaneous pneumothorax, 7 patients for hemopeumothorax, and 18 cases because of recurrence after bullectomy (7.7 ％, 18/232).all the patients were accepted bullectomy with or without dissection of pulmonary ligament.Results Between 112 patients who underwent upper lobe bullectomy with dissection of pulmonary ligament, at 1 st postoperative day, it was found 92 patients whose pleural effusion were less than 300 ml (82.1％ ,92/112);20 patients whose pleural effusion were greater than or equal to 300 ml(17.9％, 20/112), and the mean drainage from thoracic cavity was(147.0 ± 61.0)ml.At 3 rd day, the mean drainage was(33.4 ± 20.0) ml.Within 23 cases who underwent lower lobe bullectomy with dissection of pulmonary ligament, the mean drainage from thoracic cavity, at 1 st postoperative day, was (155.2 ±41.1)ml,and the mean drainage, at the 3rd day, was(52.1 ± 21.3)ml.Also,within 90 patients who underwent bullectomywithout dissection of pulmonary ligament, 9 patients whose pleural effusion, at 1 st postoperative day, were less than 300ml(10％ ,9/90);81 patients whose pleural effusion were greater than or equal to 300ml (90％, 81/90);the mean drainage for 90 patients was(65.1 ± 28.0)ml.At the 3rd day, 40 patients' pleural effusion were greater than or equal to 300ml (44.4％,40/90) , and the mean drainage was(40.2 ± 25.5) ml.2 of 7 hemopeumothorax patients bled for the vessels injury during pulmonary ligament avulsion.Conclusion There was significant difference in clinical outcomes between two groups, and the dissection of pulmonary ligament was able to reduce the pooling of pleural effusion, facilitate the drainage of pleural effusion, and prevent pneumothorax recurrence, but there is no convincing evidence that dissection of pulmonary ligament can lead to bronchial deformation, stenosis, and reduce the free thoracic space.
ABSTRACT
Objective To determine how the pulmonary ligament affects the helical CT appearances of the lower thoracic disease on the basis of the anatomic findings. Methods Four cadavers were cut transversely, with the section thickness of 11.3-13.4 mm. 57 patients with the lower thoracic disease were scanned using Somatom Plus 4, with administration of intravenous contrast material. The correlation of the anatomic findings of the pulmonary ligament and the helical CT appearances of the lower thoracic disease was evaluated. Results On cadaver sections, the right pulmonary ligament attached the lower lobe of the right lung to the esophagus, while the left ligament attached the lower lobe of the left lung to the esophagus or the descending aorta. In 40 pleural effusion and 7 pneumothorax cases, the pulmonary ligament tethered the medial aspect of the collapsed lower lobe and limited the shift of the lower lobe. In 40 pleural effusions, the ligament divided the medial pleural space into an anterior and a posterior compartment. The ligament showed thickness due to the invasion of the lesions of lower lobe including 7 tumors and 3 inflammatory diseases. Conclusion The pulmonary ligament can affect the helical CT appearances of the lower thoracic disease, such as lobe collapse, pleural effusion and pneumothorax; while the intraparenchymal and mediastinal abnormality can extend into the pulmonary ligament.
