ABSTRACT
Objective:To investigate the application value of fluorescence imaging in single-port thoracoscopic anatomic segmentectomy.Methods:The clinical data of 280 patients (145 patients with fluorescence method and 135 patients with modified inflation-deflation method) who underwent thoracoscopic anatomic segmentectomy were retrospectively studied in the Anhui Chest Hospital from June 2020 to June 2021. There were 113 patients in the simple segmentectomy group and 167 patients in the complex segmentectomy group. The baseline data of the fluorescence method and the modified inflation-deflation method in the complex segmentectomy group were corrected by propensity score matching, and the perioperative results were compared between the groups.Results:There were no significant differences in segmental resection time, intraoperative blood loss, postoperative drainage, postoperative pain, postoperative extubation time, length of hospital stay, incidence of complications and cost of hand-holding between the fluorescence method and the modified method of the simple segmentectomy group.In the complex segmentectomy group, the time of segmental resection with the fluorescence method was significantly shorter than that with the modified inflation-deflation method( P<0.05), and other indexes had no significant difference. Conclusion:Fluorescence method single-port thoracoscopic anatomic segmentectomy has the same perioperative safety and short-term efficacy as modified inflation-deflation method, which can significantly shorten the operative time and improve the operative efficiency in complex anatomic segmentectomy.
ABSTRACT
@#Objective To summarize the clinical experience of surgical resection of synchronous multiple ground-glass nodules (SMGN), and explore the individualized diagnosis and treatment strategy of SMGN. Methods Clinical data of 84 patients with SMGN who underwent thoracic surgery in Anhui Chest Hospital from July 2016 to August 2018 were analyzed retrospectively, including 18 males (21.4%) and 66 females (78.6%), aged 32-80 (55.6±10.3) years. The results of operation and the information of GGNs were analyzed. Results Except for 1 patient who was converted to thoracotomy due to extensive dense adhesion of thoracic, other patients underwent video-assisted thoracoscopic surgery successfully. All patients recuperated successfully after operation, without severe perioperative complications or death. Finally, 79 patients were diagnosed as malignant tumors (94.0%), and 5 patients of benign lesions (6.0%). A total of 240 GGNs were removed, among which there were 168 pGGNs, including 68 benign lesions (40.5%) and 100 malignant tumors (59.5%), and 72 mGGNs, including 2 benign nodules (2.8%) and 70 malignant tumors (97.2%). Nodules diameter (P<0.001), consolidation/maximum diameter of nodule ratio (P<0.001), vacuole sign (P<0.001), air bronchograms sign (P=0.001), spine-like process (P=0.001), pleural indentation sign (P<0.001), lobulation sign (P<0.001), and vascular convergence (P=0.002) were correlated with malignant tumor. Conclusion Analysis of the imaging features of GGNs by thin-section CT scan and three-dimensional reconstruction is of great value in predicting the benign and malignant nodules, which can guide the surgical decision-making and preoperative planning. Through reasonable preoperative planning and following certain principles, simultaneous surgical treatment for SMGN is safe and feasible.
ABSTRACT
Objective:To explore the clinical characteristics of cryptococcus neoformans patients who suspected as lung cancer and treated with surgery, and to improve the diagnosis of the disease.Methods:A retrospective analysis on clinical data(including preoperative laboratory examination, chest CT imaging and postoperative pathology) of 21 cryptococcosis neoformans patients misdiagnosed as lung cancer in our hospital from February 2016 to July 2019.Results:Among the 21 patients, 17 cases were single nodules and 4 cases were multiple nodules, among which 15 cases were highly suspected malignancy. The postoperative pathological diagnosis was cryptococcal pulmonary granulomatosis. 14 patients were treated with antifungal therapy after surgery. No recurrence was found after postoperative follow-up.Conclusion:The clinical manifestations and imaging examination of pulmonary cryptococcus neoformans patients have no obvious specificity, and it is easy to be misdiagnosed as early lung cancer. The diagnosis can only be confirmed by the combination of various means such as regular follow-up, laboratory examination, percutaneous lung puncture or surgical biopsy.
ABSTRACT
Objective To compare the advantages and disadvantages of uniportal video-assisted thoracic surgery(uniportal-VATS)and three portal VATS in treatment of benign pulmonary diseases. Methods The clinical data of 66 patients with benign pulmonary disease treated by VAST from June 2015 to October 2016 were retrospec-tively analyzed. The patients were divided into two groups according to the specific operation. There were 32 patients (18 males and 14 females)in uniportal-VATS group. There were 34 patients(18 males and 16 females)in three portal VATS group. The operative time ,intraoperative blood loss ,thoracic drainage volume at 24 h after opera-tion,incision length,and the time of postoperative drainage of thoracic cavity,postoperative third day pain score and complication rate were compared between the two groups. Results The patients in the experimental and the control groups were successfully operated according to the scheduled protocol. No thoracotomy was performed. There was no statistical difference in the volume of blood loss,the volume of pleural drainage after 24 hours,the time of postoperative drainage of thoracic cavity ,the length of hospital stays and postoperative complications in uni-portal-VATS group and three portal VATS group(P>0.05). The pain score and postoperative third day pain score of the uniportal-VATS group was better than that of the three portal VATS group(P<0.05),but the operation time of the uniportal-VATS group was longer than that of the three portal VATS group(P<0.05). Conclusion Uniportal-VATS is safe and feasible for the treatment of benign lung diseases. It is more minimally invasive and beautiful than traditional three-hole thoracoscopic surgery. It is worthy of promotion and has broad prospects.
