Thoracic drainage with traditional chest tube versus central venous catheter after video-assisted thoracoscopic lobectomy: A randomized controlled study / 中国胸心血管外科临床杂志

@#Objective    To evaluate the effectiveness and safety of a central venous catheter for thoracic drainage after video-assisted thoracoscopic lobectomy compared with a conventional chest tube. Methods    This study collected 200 patients with lung cancer who underwent thoracoscopic lobectomy and systematic hilar and mediastinal lymph node dissection between January 2018 and September 2019 in our hospital. The patients were randomly divided into two groups, including a group A (left with 28F chest tubes postoperatively) and a group B (left with 12G central venous catheters postoperatively). Patients in both groups were left with 2 chest tubes after upper lobectomy and 1 chest tube after middle or lower lobectomy. Duration and total volume of drainage, length of hospital stay, maximum visual analogue scale score and so forth were compared between the two groups. Results    Finally, 151 patients were included for analysis. There were 73 patients in the group A, including 26 males and 47 females, with an average age of 55.38±9.95 years, and 78 patients in the group B, including 37 males and 41 females, with an average age of 59.86±10.18 years. No statistical  difference was found between the two groups in drainage volume on postoperative day 2, and proportion of prolonged air leaks, hemothorax, chylothorax or drain reinsertion (all P>0.05). There was a statistical difference in drainage volume on postoperative day 1 [200.0 (120.0, 280.0) mL vs. 57.5 (10.0, 157.5) mL, P=0.000], postoperative day 3 [155.0 (100.0, 210.0) mL vs. 150.0 (80.0, 215.0) mL, P=0.023], total volume of drainage [890.0 (597.5, 1 530.0) mL vs. 512.5 (302.5, 786.3) mL, P=0.000], maximum pain score (2.29±0.72 points vs. 2.09±0.51 points, P=0.013) and length of hospital stay [7 (7, 9) d vs. 5 (4, 7) d, P=0.000]. Conclusion    Compared with conventional chest tubes, central venous catheters for chest drainage in patients with lung cancer after thoracoscopic lobectomy shortens the length of hospital stay and reduces postoperative pain.

Accuracy and technical feasibility of mutual corroboration in the diagnosis of pulmonary nodule: A report of 1 368 cases / 中国胸心血管外科临床杂志

@#Objective    By applying the mutual corroboration in the diagnosis, we aimed to improve the accuracy of preoperative imaging diagnosis, select the appropriate timing of operation and guide the follow-up time for patients with pulmonary nodules. Methods    Clinical data of 1 368 patients with pulmonary nodules undergoing surgical treatment in our department from July 2016 to October 2019 were summarized. There were 531 males and 837 females at age of 44 (21-67) years. The intraoperative findings, images and pathology were classified and analyzed. The imaging pathology and pathological changes of pulmonary nodules were shown as a dynamic process through mutual collaboration and interaction. Results    Of 1 368 patients with pulmonary nodules, 376 (27.5%) were pure ground-glass nodules, 729 (53.3%) were mixed ground-glass nodules and 263 (19.2%) were solid nodules. Among the pure ground-glass nodules, adenocarcinoma in situ (AIS) accounted for the highest proportion (156 patients), followed by microinvasive adenocarcinoma (MIA, 90 patients), atypical adenomatous hyperplasia (AAH, 85 patients), and benign tumors (20 patients). Among mixed ground-glass nodules, 495 patients were invasive adenocarcinoma (IA) and 207 patients of MIA. no patient was featured by AAH, AIS or MIA. Conclusion    The mutual collaboration and interaction can improve the accuracy of preoperative diagnosis of pulmonary nodules, and it supports the choice of operation timing and the judgment of follow-up time.

Comparison of HRCT imaging features of ground glass opacity of COVID-19 and early-stage lung carcinoma / 中华胸心血管外科杂志

Objective:To investigate the difference of HRCT imaging features between COVID-19 and the ground-glass opacity(GGO) lesion of early-stage lung carcinoma, standardize the diagnosis and treatment process of ground-glass opacity(GGO) degeneration during the epidemic.Methods:A total of 34 patients with diagnosed COVID-19 who confirmed by positive results of the new coronavirus nucleic acid test were collected as observation group 40 patients with pathologically diagnosed early-stage lung carcinoma whose preoperative HRCT examination showed pure ground glass lesions and received surgical intervention were recruited from the Department of Thoracic Surgery (The First Affiliated Hospital of Xiamen University) from January 2018 to December 2019 as the control group. The HRCT imaging features of these two groups of patients were compared and statistically analyzed.Results:The HRCT imaging features of the new type of COVID-19 showed significant difference by characteristics of multiple lesions, lesion rapid variation within 3 days, reticular pattern, vacuolar sign and clear boundary compared to the GGO lesion of early-stage lung carcinoma( P<0.05). The chinical and imaging characteristic the sex, age, with pleural effusion or not and the lesion location showed no significant difference between these 2 groups ( P>0.05). Conclusion:Contrast with inert early lung carcinoma lesions, COVID-19 disease developed rapidly. Imaging dynamic examination can provide evidences to distinguish Novel Coronavirus Pneumonia and early-stage lung carcinoma.

One stage surgical treatment of multiple primary carcinoma of hypopharynx and esophagus / 中国耳鼻咽喉头颈外科

OBJECTIVE To discuss the therapeutic effect of one stage surgical treatment in the multiple primary hypopharyngeal and cervical thoracic esophageal carcinoma.METHODS The thoracoscopy group: dissecting the esophagus and mediastinal lymph node assisted with thoracoscope, and then opened abdominal cavity to make gastric tube. Head and neck group: doing the cervical lymph node dissection, total laryngectomy, total hypopharyngectomy and total esophagectomy, and then anastomosis of the pharynx with gastric tube. All cases were received conventional radiotherapy and chemotherapy after operation.RESULTS All the cases in this group were successfully underwent the one stage operation. The postoperative complications were pulmonary infection in 3 cases, pleural effusion in 2 cases and tracheal tear in one case. No anastomotic fistula or postoperative deaths occurred. The 3 and 5 year survival rates were 63.6% and 50.0% respectively.CONCLUSION It should take necessary examinations of cervical thoracic esophagus to prevent missing the multiple primary carcinoma of the hypopharyngeal carcinoma. The total laryngectomy, total hypopharyngectomy and total esophagectomy, and anastomosis of the pharynx with gastric tube for multiple primary hypopharyngeal and cervical thoracic esophageal carcinoma is a feasible and active treatment method.

Three-dimensional versus two-dimensional imaging systems in thoracoscopic lobectomy for lung cancer in different year / 中国医师杂志

Objective To compare the clinical application of three-dimensional (3D) and two-di-mensional (2D) imaging systems in thoracoscopic lobectomy for non-small cell lung cancer ( NSCLC). Methods In 2014 and 2016, the patients with NSCLC undergoing thoracoscopic lobectomy with 2D or 3D imaging systems were performed by a single experienced surgeon. The baseline characteristics and perioper-ative data of the patients were collected and analyzed. Results In 2014, 19 patients underwent 3D thora-coscopic lobectomy and the other 23 patients underwent 2D thoracoscopic lobectomy. Compared to 2D thora-coscopic lobectomy group, 3D thoracoscopic lobectomy group had a significantly shorter operative time [(147.0 ±23.9)min vs (179.1 ±54.4)min,P=0.016], a smaller volume of intraoperative blood loss [(142. 1 ± 69. 3)ml vs (203. 0 ± 90. 4)ml,P=0. 018]. In 2016, 36 patients underwent 3D thoracoscopic lobectomy and the other 32 patients underwent 2D thoracoscopic lobectomy. No significant differences were found between two groups in terms of preoperative indicators. Conclusions To some extent, 3D thoracos-copy reduces the operation difficulty, shortens the operative time and reduces intraoperative blood loss. However, with the accumulation of surgical experience, 2D can effectively compensate for the disadvantages of thoracoscope.
