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 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 clearly define and describe the difference of analgesic actions and side effects between dezocine and parecoxib sodium in video-assisted thoracic surgery (VATS) lobectomy. Methods Ninety patients underwent thoracotomy (lobectomy) and were hospitalized in the Department of Thoracic Surgery, West China Hospital, Sichuan University between August 2015 and January 2016. Patients were randomly divided into two groups including a parecoxib sodium group (a PG group, 43 patients) and a dezocine group (a DG group, 47 patients). We analyzed the occurrence of side effects in the two groups, as well as other outcomes including visual analogous scores and location of the pain et al. Results The occurrences of nausea, vomit and abdominal distention in the PG group (9.30%, 2.33%, 13.95%) were significantly lower than those of the DG group (25.53%, 17.02%, 40.43% , P=0.046, P=0.032, P=0.009) in the early period after operation. Pain scores at the postoperative 12 h, 24 h, 48 h and 72 h in the PG group (2.56±0.96, 2.47±0.96, 1.93±0.99, 0.98±1.24) were better than those of the DG group (4.00±1.60, 3.62±1.48, 3.36±1.55, 2.47±1.78, P=0.000, P=0.000, P=0.000, P=0.002). And the same results were found in the postoperative coughing VAS assessment. The mostly reported pain location was the chest drainage, incision site and chest wall in turn. Postoperative pain properties, in turn, were swelling, stabbing pain and numbness. Conclusion Postoperative pain after VATS lobectomy may be adequately controlled using parecoxib sodium. The low pain scores and decreased adverse effects are achieved.
ABSTRACT
Reproductive lifespan in female mammals is related to the size of primordial follicles pool, which relies on the balance between activated and quiescent primordial follicles. Therefore, the molecular mechanisms of recruiting and maintaining quiescence of primordial follicles have become hot research topics recently. Multiple studies have shown that genetic mutations, local ovarian autocrine and paracrine factors, proto-oncogene and tumor-suppressor genes are involved in the maintenance of balance between quiescent and activated primordial follicles. In the present review, we summarize recent research progress of the important signaling molecules and pathways that maintain the quiescence of primordial follicles.
