ABSTRACT
@#With the development of technology, the detection rate of ground-glass opacity (GGO) is rapidly increasing. GGO comprises of pure GGO and mixed GGO. Many researches have studied the characteristics of GGO, and they found that different malignant probability of GGO was associated with different image characteristics. It is obvious that there is a close relationship between the image characteristics of GGO and its prognosis. However, due to the various image characteristics of GGO, it is essential to assess the prognosis of lung adenocarcinoma patients in a more comprehensive way. In this review, we summarize the correlation between the main GGO image features (solid proportion, size, mean CT value, shape characteristics) and the prognosis of lung adenocarcinoma patients, to provide clinical reference for prognosis prediction and decision-making for patients with lung adenocarcinoma.
ABSTRACT
@#Objective To assess the specific clinicopathological characteristics as well as prognostic value of prognostic significance of spread through air spaces (STAS) in lung adenocarcinoma. Methods We systematically searched the databases of PubMed, EMbase and Web of Science databases from their date of inception to March 2019. The quality of the included literature was assessed by the Newcastle-Ottawa scale (NOS). The NOS of the study higher than 6 points was considered as high quality. Software of Stata 12.0 was used for meta-analysis. Results Twenty retrospective cohort studies involved with totally 6 225 patients were included. Quality of included studies was high with NOS score equal or higher than 6 points. STAS was associated with male sex, ever smoking history, abnormal carcino-embryonic antigen (CEA) level, air bronchogram negative, anaplasticlymphoma kinase (ALK) arrangement positive, epidermal growth factor receptor (EGFR) mutation positive, advanced pathological tumor stage and more invasive pathological adenocarcinoma subtypes. The presence of STAS indicated significantly poor recurrence free survival (RFS) (HR=1.960, 95%CI 1.718-2.237, P<0.001) as well as poor overall survival (OS) (HR=1.891, 95%CI 1.389-2.574, P<0.001). Further subgroup analyses showed that exhibiting tumor size including diameter less than 2 cm (HR=2.344, 95%CI 1.703-3.225, P<0.001) and diameter over 2 cm (HR=2.571, 95%CI 1.559-4.238, P<0.001), resection type including lobectomy (HR=1.636, 95%CI 1.258-2.127, P<0.001) and sublobar resection (HR=3.549, 95%CI 2.092-6.021, P<0.001) in stageⅠ adenocarcinoma suggested that STAS had a bad effect on RFS. Conclusion Presence of STAS is associated with more aggressive clinicopathological features and independently associated with worse RFS and OS in lung adenocarcinoma. STAS positive has a negative effect on RFS whatever the tumor size (including the diameter<2 cm or >2 cm) and resection types in stageⅠ adenocarcinoma.
ABSTRACT
@#A new independent subtype CD4+ T cell which massively secreted interleukin-17 (IL-17) was found at the beginning of the 21st century, and thus it was named as T helper cell 17 (Th17 cell). With the progress of the research in recent years, Th17 cells were found to be widely involved in a variety of the human diseases such as autoimmune diseases, infections and tumors through secretion of IL-17. The relationship between Th17 cells, IL-17 and the occurrence, development and prognosis of lung cancer was reviewed.
ABSTRACT
@#Foreign body ingestion is common in emergency. The vast majority of foreign body ingestion occurs in the pediatric population as well as mentally impaired and edentulous adults. The typical clinical manifestation of foreign body ingestion includes acute onset of dysphagia and chest pain. Most of the ingested foreign bodies pass without the need of intervention; however, about 20% of esophageal foreign body ingestion requires endoscopic removal. While less than 1% will need surgery for foreign body extraction. Timely diagnosis and proper treatment are associated with low mortality and morbidity rate, while delayed diagnosis and improper treatment always lead to severe complications such as esophageal perforation and death. This article reviews the diagnosis and treatment of adult esophageal foreign body ingestion.
ABSTRACT
@#Objective To explore the safety and effectiveness of video-assisted thoracoscopic surgery (VATS) pneumonectomy for bronchiectasis. Methods The clinical data of 164 patients undergoing VATS pneumonectomy or open thoracotomy for bronchiectasis in our hospital from March 2002 to July 2012 were retrospectively analyzed. Patients were divided into two groups according to different surgical methods: a thoracotomy group (122 patients, 63 males, 59 females) and a thoracoscopic surgery group (42 patients, 15 males, 27 females). Surgical and follow-up indicators were compared between the two groups. Results There was no difference between the two groups in the blood loss, operation time, perioperative mortality or complication. However patients undergoing VATS had shorter length of postoperative stay than those undergoing thoracotomy (6.9±2.6 d vs. 8.1±3.1 d, P=0.030). In the thoracoscopic surgery group, 3 patients were lost to follow-up and in the thoracotomy group, 5 patients were lost to follow-up. In a median follow-up of 51 months (ranging from 2 to 116 months), 36 patients (92.3%) fully recovered with no sputum or haemoptysis and 3 (7.7%) partially recovered with a reduced sputum or haemoptysis in the thoracoscopic surgery group; 105 (89.7%) fully recovered with no sputum or haemoptysis, 10 (8.5%) partially recovered with a reduced sputum or haemoptysis while 2 (1.7%) without any improvement in the thoracotomy group with no statistical difference (P=0.700). Conclusion VATS pneumonectomy for bronchiectasis is equivalent to thoracotomy in terms of safety and effectiveness, and can be used as an alternative surgical procedure for the treatment of bronchiectasis.
ABSTRACT
@#Objective To compare the differences in the application of ultrasound scalpel and coagulation hook in thoracoscopic anterior mediastinal tumor surgery and to analyze the respective advantages and indications of the two commonly used energy instruments. Methods The clinical data of 85 patients undergoing thoracoscopic anterior mediastinal tumor surgery in West China Hospital of Sichuan University between June and November in 2017 were prospectively analyzed. There were 45 males and 40 females at age of 50.45 (18–75) years. The patients were divided into three groups including a ultrasound scalpel group (59 patients), a coagulation hook group (17 patients) and a mixed group (9 patients) according to the using time of energy devices. The clinical effect among the three groups were compared. Results No significant difference was found among the three groups in operation time, blood loss, average duration of chest tube drainage or volume of drainage (P>0.05). No significant complications occurred in all groups during operation or after operation. The proportion of subxiphoid approach in the ultrasound scalpel group was higher than that in the other two groups (49/59 vs. 7/17 vs. 5/9, P<0.01). The maximum diameter of the tumor (4.58±2.19 cm vs. 4.05±1.07 cm vs. 3.00±1.45 cm, P<0.05) and the resected tissue weight (103.67±74.78 g vs. 61.17±31.97 g vs. 61.86±34.13 g, P<0.05) were also significantly greater than that in the coagulation hook group or the mixed group. Conclusion Ultrasound scalpel has good safety and reliability in the thoracoscopic anterior mediastinal tumor surgery, and is more suitable for operation in a narrow space.
ABSTRACT
@#Objective To evaluate the effectiveness and safety of single-incision video-assisted thoracic surgery versus conventional multiple ports video-assisted thoracic surgery in the treatment of lung cancer as well as providing reference for clinical decision-making. Methods We searched the Cochrane Library, PubMed, EMbase, CBM, CNKI, VIP, Wanfang ect until March 2017 to collect randomized controlled trials (RCTs), cohort studies, and case-control studies comparing single-incision with conventional multiple ports video-assisted thoracic surgery for lung cancer.Two reviewers independently screened and selected literatures according to inclusion and exclusion criteria. Then data extraction and quality assessment of included studies were conducted. RevMan 5.3 software was used for meta-analysis. Results Twenty-six cohort studies (3 053 patients) were included. The quality of the included studies was high with score more than five.Meta-analysis showed that single-incision video-assisted thoracic surgery had shorter thoracic drainage time (MD=–0.71, 95% CI –1.03 to –0.39), shorter hospitalization time (MD=–0.92, 95% CI –1.66 to –0.19), lower pain scores 1 day after surgery (MD=–0.65, 95% CI –0.90 to –0.40), lower pain scores 3 days after surgery (MD=–0.90, 95% CI –1.16 to –0.64), lower pain scores 7 days after surgery (MD=–1.24, 95% CI –1.90 to –0.57), less number of lymph node dissection (MD=–0.72, 95% CI –1.35 to –0.10), less total drainage fluid (MD=–108.60, 95% CI –180.42 to –36.79) and shorter length of surgical incision (MD=–2.74, 95% CI –3.57 to –1.90) than conventional multiple ports video-assisted thoracic surgery. But the differences between the two groups in operation time, intraoperative blood loss, postoperative complications were not statistically significant. Conclusion Single-incision video-assisted thoracic surgery is safer and better in patient's compliance than conventional multiple ports video-assisted thoracic surgery in the treatment of lung cancer. But there is no significant difference in operation time, intraoperative blood loss, or postoperative complications. It still needs large-scale, high-quality studies to demonstrate its effectiveness and safety.
ABSTRACT
@#Objective To explore the effect of standardized use of antibiotics on clinical indicators after thoracic surgery, such as pulmonary infection rate, incision infection rate, average length of hospital stay and total hospitalization cost. Methods We selected 468 patients (an observation group) who were hospitalized and received thoracic surgery from August to October 2011, 3 months after the implementation of the preventive antibiotics use protocol for thoracic surgery in West China Hospital, Sichuan University, and selected 343 patients (a control group) in the same period of the previous year (from August to October 2010). There were 326 males and 142 females with a mean age of 52.0±15.5 years in the observation group, and 251 males and 92 females with a mean age of 51.4±15.9 years in the control group. The level of antibiotic use, medication time, antibiotics cost, postoperative incision infection, incidence of pulmonary infection, postoperative hospital stay and total hospitalization cost were compared between the two groups. Results Compared with the control group, the time for preventive use of antibiotics was significantly shorter in the observation group (3.6±2.4 d vs. 6.1±3.1 d, P=0.020) and the total cost of antibiotic use significantly reduced (1 230.0±2 151.0 yuan vs. 2 252.0±1 764.0 yuan, P<0.001). There was no significant difference between the two groups in hospitalization cost (36 345.0±13 320.0 yuan vs. 35 821.0±11 991.0 yuan, P=0.566), postoperative hospital stay (10.6±8.4 d vs. 10.7±5.3 d, P=0.390), the incidence of postoperative wound infection or postoperative pulmonary infection (1.5% vs. 2.3%, P=0.430; 19.2% vs. 22.2%, P=0.330). Conclusion The standardized use of antibiotics in thoracic surgery does not cause postoperative pulmonary infection and incision infection, and has no negative impact on clinical indicators. Significantly reducing the level of antibiotics use may have a positive effect on reducing medication time, in-hospital infection and the incidence of drug-resistant strains.
ABSTRACT
@#Objective To analyze the current status and difficulties of ERAS applicated in thoracic surgery in different regional hospitals. Methods A total of 773 valid questionnaires were collected during the First West China Forum on Chest ERAS and analyzed by geographical distribution. The content of the questionnaire was divided into two parts, including the respondents’ institute and personal information, as well as 10 questions about ERAS. Results There were 83.57%, 83.82%, 89.58%, 93.75%, 94.74% and 92.86% of surgeons and nurses in Sichuan province, municipalities, the eastern, western, southern and northern respectively who believed that ERAS in all surgeries should be used. There were 61.84%, 60.29%, 65.97%, 81.25%, 73.68% and 75.00% of surgeons and nurses who thought that the concept of ERAS was more in the theory than in the practice; 77.99%, 80.88%, 74.31%, 78.13%, 83.33%and 69.64% of respondents agreed that average hospital stay, patients’ experience and social satisfaction should be the evaluation standard of ERAS practice while 58.50%, 63.24%, 54.86%, 62.50%, 70.18% and 58.93% of respondents believed that immature procedure, lack of consensus and specifications and insecurity for doctors were the reasons for poor compliance of ERAS; 63.23%, 67.65%, 59.72%, 68.75%, 72.81% and 67.86% of respondents thought that the best team of ERAS should be based on the combination of subject integration, surgery orientation and surgeon-nurse teamwork; 43.73%, 44.12%, 43.75%, 46.88%, 59.65% and 41.07% of respondents thought that multidisciplinary cooperation, multi-modality conducted and surgical programming should be the best way for ERAS implementation; 72.98%, 69.12%, 62.50%, 65.63%, 80.70% and 55.36% of responders agreed that the ERAS forum or conference should include the norms and consensus, analysis and implementation of projects and the status and progress of ERAS. Conclusion There are more consistent views on the clinical application of ERAS in all regions. The subject integration, surgeon-nurse teamwork and multidisciplinary, multi-modality cooperation are the best team and best way for ERAS program implementation.
ABSTRACT
@#Objective We conducted a questionnaire study who attended the First West China Forum on Chest Enhanced Recovery after Surgery (ERAS) in order to analyze whether it can improve the knowledge of ERAS and how to organize an effective meeting. Methods We analyzed 188 questionnaires from the representatives of the First West China Forum on Chest ERAS after the meeting which included two parts: one was the personal basic information and institution of respondents, and the other was the opinion of the content setting and suggestion for the next forum. Results A percentage of 97.7% of participants believed that this forum contributed to improving their understanding of ERAS and 65.3% of them will put the concept of ERAS into practice after the meeting. The exchange of experience and project communication of ERAS were the most useful agendas approved by representatives while expert lectures should be more appropriate (18.1%). Arrangement for topic discussion and enough time for discussion were supported by 93.1%and 98.9% of the representatives respectively. Multi-center project discussion (80.9%) and interactive sessions especially WeChat interaction (74.0%) should be added on ERAS forum. Conclusion Reasonable agenda settings are beneficial to improve the understanding and compliance of application of ERAS.
ABSTRACT
@#Objective To present the preliminary clinical experience of robot assisted trans-subxiphoid (extended) thymectomy in patients with thymic neoplasms or myasthenia gravis. Methods A total of 62 patients (34 males and 28 females at an average age of 38±11 years) suffering from thymic neoplasms or myasthenia gravis who underwent robotic (extended) thymectomy via subxiphoid approach were included in our department between August 2016 and August 2017. All of the operation were completed through 4 ports. In details, the observation hole was created just below the xiphoid process, two ports for arm 1 and arm 2 were created below bilateral subcostal arch at the midclavicular line, and trocar for arm 3 was placed in the 5th or 6th intercostal space at the anterior axillary line, respectively. Patients with thymic neoplasms received thymectomy. Patients with myasthenia gravis received extended thymectomy. Results All the patients experienced uneventful operations. The mean operative time was 116.0±34.0 min. The mean intraoperative blood loss was 5.6±4.3 ml. The mean postoperative hospital stay was 4.0±2.2 days. There was no intra-operational massive hemorrhage, mortality, conversion or postoperative complication during the postoperative and follow-up period. Conclusion Robotic trans-subxiphoid thymectomy is safe and feasible, which is a promising technique for extensive application.
