  • Diagnosis and treatment of adult esophageal foreign body ingestion

    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.

  • A Questionnaire Study Investigating Current Application Status of Video-assisted Thoracoscopic Surgery of ThoracicSurgeons in Some Municipal Hospitals in China

    Objective To explore current view and application status of video-assisted thoracoscopic surgery (VATS) of thoracic surgeons in some municipal hospitals in China,and provide evidence for further VATS study and training.Methods We conducted a questionnaire study for thoracic surgeons in municipal hospitals who attended the 5th West China Forum on Mini-invasive Thoracic Surgery in 2012. The questionnaire content included general descriptions of the thoracic surgeons,the departments of thoracic surgery where they worked,and VATS application status in their hospitals. A total of 263 surgeons were investigated,and 183 (69.58%) valid questionnaires were collected for descriptive analysis.Results (1) Responders’ view of VATS:There were 89.62% (164/183) responders who believed that the advantages of VATS were mainly mini-invasive and fast postoperative recovery,while its disadvantage was high cost (76.50%,140/183). There were 71.04% (130/183) responders who thought that VATS lobectomy could provide a higher postoperative quality of life for lung cancer patients,while only 12.57% (23/183) responders thought that the 5-year survival rate of VATS was higher than that of open thoracotomy. There were 60.11% (110/183) responders who believed that VATS was less widely performed in China than America,but VATS level of very few hospitals in China was superior or equal to American level. There were 52.46% (96/183) responders who agreed that VATS could be used for the treatment of locally advanced lung cancer. (2) Training situation of VATS lobectomy for lung cancer:Learning class or short-term training (32.24%,59/183) was the best way to learn VATS lobectomy. Their main learning process was from open thoracotomy to mini- thoracotomy then to VATS (60.66%,111/183). Single-direction thoracoscopic lobectomy was the most popular VATS technique (54.64%,100/183),and its learning curve was at least 30 cases (26.78%,49/183). (3) VATS application status:VATS was performed in all the hospitals investigated. Benign thoracic diseases were most commonly chosen by thoracic surgeons who started to perform VATS (81.42%,149/183). The main initial hurdles of VATS lobectomy for lung cancer included poor operation theater conditions and surgical teamwork (39.34%,72/183) as well as unsatisfactory surgical techniques (36.07%,66/183). Further improvement of VATS technique (118/183,64.48%) was the developmental trend of VATS. Conclusions Thoracic surgeons in China have reached the consensus on the application of VATS for surgical treatment of thoracic diseases including lung cancer. Single-direction thoracoscopic lobectomy is a widely accepted technique. Further trends of VATS training and development are equipment upgrade and better teamwork.

  • The relationship between pure solid non-small cell lung cancer with diameter less than 2 centimeter and lymph node metastasis

    Objective To explore the relationship between pure solid non-small cell lung cancer with diameter<2 cm and lymph node metastasis rate. Methods We retrospectively analyzed clinicopathological data of 611 patients who underwent lobectomy and systematic lymph node dissection in our hospital between October 2005 and September 2016. There were 322 males and 289 females aged 58.8±10.0 years (range from 25 to 84 years). The relationship between clinicopathological feature and lymph node metastasis rate was analyzed by logistic regression. Results Lymph node metastasis was observed in 136 patients. The rate of lymph node metastasis was 22.3% in pure solid non-small cell lung cancer with diameter<2 cm. The result of univariate analysis showed that differentiation of tumor (P<0.001), location of tumor (P=0.047) and gender (P=0.032) were associated with lymph node metastasis. Multivariate analysis showed that differentiation of tumor was an independent risk factor for lymph node metastasis (P<0.001). Conclusion The rate of lymph node metastasis is high in pure solid non-small cell lung cancer with diameter<2 cm. Differentiation of tumor is an independent risk factor for lymph node metastasis. We recommend systematic lymph node dissection in the patients of this group. And we should choose sublobar resection prudentially.

    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 (49/59vs. 7/17 vs. 5/9, P<0.01). The maximum diameter of the tumor (4.58±2.19 cmvs. 4.05±1.07 cm vs. 3.00±1.45 cm, P<0.05) and the resected tissue weight (103.67±74.78 gvs. 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.

  • The effect of perioperative use of antibiotics on clinical indicators of thoracic surgery: A case control study

    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 yuanvs. 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.

  • Progress in ablation therapy of pulmonary nodules

    [Abstract]In recent years, with the improvement of people's awareness of physical examination and the more accurate detection equipment, the detection rate of pulmonary nodules is getting higher and higher. Surgical resection is the first choice for the treatment of malignant pulmonary nodules, but multiple pulmonary nodules, nodules in complex areas and those with surgical contraindications are not suitable for surgery. As an effective, less invasive and low-cost treatment, ablation has developed rapidly in the treatment of multiple pulmonary nodules. This paper reviews the progress of several common ablation treatments in the treatment of multiple pulmonary nodules.

  • Clinical Analysis of 17 Patients with Chest Injuries in Lushan Earthquake

    Objective To summarize our treatment experience for patients with chest injuries in “4•20” Lushan earthquake. Methods Medical records of 17 patients with chest injuries after 2013 Lushan earthquake who were admittedto the Department of Thoracic Surgery,West China Hospital were analyzed retrospectively. The diagnosis of chest injuries was mainly confirmed by medical history,physical examination,X-ray and CT scan of the chest. Clinical characteristics and treatment outcomes were analyzed. Among the 17 patients,there were 14 men and 3 women with their age of 57.3±16.1 years. Results There were 12 patients (70.6%)with crash injury of heavy objects,4 patients (23.5%) with fall injury and 1 patient with road traffic injury. Chest injuries were skin and soft tissue contusion in 17 patients (100%),rib fracturein 15 patients (88.2%) including 1 patient with abnormal respiratory movements,pulmonary contusion in 15 patients (88.2%),hemopneumothorax in 11 patients (64.7%),sternal fracture in 1 patient (5.9%) and bilateral pneumothorax with widespread subcutaneous emphysema in 1 patient (5.9%). Thirteen patients (76.5%) had concomitant brain,abdominal,orthopedic or nerve injuries. One patient underwent left thoracotomy,clot removal and internal fixation of rib fractures for left coagulated hemothorax and left lower lobe atelectasis. All the 17 patients received timely and effective treatment and there was noin-hospital mortality. Conclusions Mechanisms of earthquake injuries are often complex,and patients often have multipleinjuries. The main types of chest injury are rib fractures and pulmonary contusion. Tube thoracostomy is a simple andeffective treatment strategy for them.

  • Survey on Rational Use of Drug in Different Ranks of Hospitals in Sichuan Province

    Objective To investigate the awareness of rational use of drug (RUD) on medical workers in hospitals of different ranks, the establishment and execution of relevant strategies in hospitals of different ranks, and the main factors affecting RUD on medical workers, so as to provide references for the generalization of RUD. Methods A certain number of different ranks of hospitals in Chengdu and Zigong were randomly selected by the convenience sample method. Medical workers in each hospital were selected through face-to-face interviews with a self-designed questionnaire. Monte Carlo Chi-square analysis was applied on the hospital ranks and formulation of RUD guidelines, and logistic regression analysis was performed on the awareness of RUD knowledge of the respondents. Results Among 700 questionnaires distributed, 672 were retrieved (response rate 96.0%). The numbers of respondents who were familiar with the Pharmaceutical Affairs Councils (PACs) as well as the Pharmacy and Therapeutics Committees (PTCs) were 217 (32.29%) and 83 (12.35%), respectively. The number of respondents who understood the concept of essential medicine was 502 (74.71%). A total of 441 (61.16%) medical workers had been trained on RUD, 199 (29.61%) medical workers denied there were PTCs in their hospitals, and 60.71% of the medical workers mentioned that the use of drug was monitored and controlled with the feedback in their hospitals. The result of logistic regression analysis indicated that the professional title (P=0.038), awareness of essential medicine (Plt;0.001) and participation of RUD training (P=0.008) were the factors influencing the awareness of RUD. Conclusion Both management and education should be executed at the same time to elevate the level of rational use of drug. In order to increase the level of RUD we should complete monitoring institution and improving RUD awareness of workers. Additionally enhancing the rationality of medication should be performed by establishing guidelines of treatment or medication. Improving personal knowledge, scientific information and medication custom should be performed by standardizing regulations, strengthening management, emphasizing education and promoting communication between doctors and patients.
