Autologous blood patch pleurodesis (ABPP) was first proposed in 1987. Now it is mainly used to treat intractable pneumothorax and persistent air leakage after pneumonectomy, and also used to treat pneumothorax in children and other rare secondary pneumothorax. Persistent air leakage and pneumothorax of various causes are essentially alveolar pleural fistula. It can usually be treated by closed thoracic drainage, continuous negative pressure suction and surgery. Pleurodesis is a safe and effective alternative to surgery for patients who have failed conventional conservative treatment and can not receive operations. Compared with other pleurodesis adhesives, autologous blood (ABPP) is safer and more effective, and it is simple, painless, cheap and easy to be accepted by patients. But in the domestic and foreign researches in recent years, many details of ABPP treatment have not been standardized. For further research and popularization of ABPP, this article reviews the detailed regulations, efficacy and safety of this technology.

Objective    To investigate the clinical effect of thoracoscopic lobectomy versus segmentectomy in the treatment of T1bN0M0 non-small cell lung cancer (NSCLC). Methods    Clinical data of 181 patients with T1bN0M0 NSCLC admitted to our hospital from 2012 to 2015 were retrospectively analyzed. They were divided into a lobectomy group and a segmentectomy group according to surgical methods. There were 117 patients in the lobectomy group (46 males and 71 females aged 61.32±8.94 years) and 64 patients in the segmentectomy group (20 males and 44 females aged 58.55±12.57 years). Perioperative indicators and prognosis were compared between the two groups. Results    The segmentectomy group had longer operation time, less intraoperative blood loss, shorter postoperative hospital stay and more preservation of lung function compared with the lobectomy group (P<0.05). The lobectomy group had higher consolidation tumor ratio, bigger tumor diameter, and more lymph node sampling compared with the segmentectomy group (P<0.05). There was no statistical difference in 5-year overall survival or recurrence-free survival between the two groups (P<0.05). Conclusion    For patients with T1bN0M0 NSCLC, thoracoscopic segmentectomy and lobectomy have similar prognosis, but segmentectomy has advantages with less injury and faster recovery over lobectomy.

<p>INTRODUCTIONThis study evaluated the data completeness in the registration of prostate cancer after robotic radical prostatectomy (RRP) in the Urological Cancer Registry at the Singapore General Hospital (SGH), and its compliance to the international standards of US Commission on Cancer (CoC).p><p>MATERIALS AND METHODSA certified cancer registrar reviewed all RRP cases between June 2003 and July 2008 in the Urological Cancer Registry at SGH.p><p>RESULTSA total of 365 cases were reviewed. The results showed that 351 (96.2%) of RRP patients' demographic data were captured and 321 (87.9%) of RRP patients were staged. According to the international standards of CoC for an academic institution, the requirement is to capture 100% of all cancer cases and stage at least 90% of them. As for data completeness, 317 (86.7%) of RRP details were captured as compared to the CoC standard requirement of 90%.p><p>CONCLUSIONSThe existing manual cancer registry does not fully meet the CoC standards. Hence, the registry increased sources of case-finding and used active case-finding. With improvements made to the data collection methodology, the number of prostate cancer cases identified has been increased by 52.1% from 215 in 2007 to 327 in 2009. The registry is expected to be fully compliant with the CoC standard with the recruitment of more full time cancer registrars when a new web-based cancer registry is in full operation.p>

Thoracoscopic minimally invasive technology has been used in mitral valve plasty since 1990s. Totally thoracoscopic mitral valve plasty has the advantages of small trauma, beautiful incision and rapid postoperative recovery. It is favored by more and more patients and cardiac surgeons. However, according to the reports, the proportion of totally thoracoscopic mitral valve surgery in China is still low. Mitral valve plasty via the totally thoracoscopic approach is still controversial in terms of population adaptation, perioperative complications and long-term prognosis. In addition, the technical difficulty and the long training cycle of surgeons also limit the popularization of this technology. By summarizing the existing literature, this paper analyzes the application and development of totally thoracoscopic approach in comparison with the traditional median thoracotomy mitral valve plasty.

Objective To examine the safety, efficacy and durability of totally endoscopic minimally invasive (TEMI) mitral valve repair in Barlow’s disease (BD). Methods A retrospective study was performed on patients who underwent mitral valve repair for BD from January 2010 to June 2021 in the Guangdong Provincial People’s Hospital. The patients were divided into a MS group and a TEMI group according to the surgery approaches. A comparison of the clinical data between the two groups was conducted. Results A total of 196 patients were enrolled, including 133 males and 63 females aged (43.8±14.9) years. There were 103 patients in the MS group and 93 patients in the TEMI group. No hospital death was observed. There was a higher percentage of artificial chordae implantation in the TEMI group compared to the MS group (P=0.020), but there was no statistical difference between the two groups in the other repair techniques (P>0.05). Although the total operation time between the two groups was not statistically different (P=0.265), the TEMI group had longer cardiopulmonary bypass time (P<0.001) and aortic clamp time (P<0.001), and shorter mechanical ventilation time (P<0.001) and postoperative hospitalization time (P<0.001). No statistical difference between the two groups in the adverse perioperative complications (P>0.05). The follow-up rate was 94.2% (180/191) with a mean time of 0.2-12.4 (4.0±2.4) years. Two patients in the MS group died with non-cardiac reasons during the follow-up period. The 3-year, 5-year and 10-year overall survival rates of all patients were 100.0%, 99.2%, 99.2%, respectively. Compared with the MS group, there was no statistical difference in the survival rate, recurrence rate of mitral regurgitation, reoperation rate of mitral valve or adverse cardiovascular and cerebrovascular events in the TEMI group (P＞0.05). Conclusion TEMI approach is a safe, feasible and effective approach for BD with a satisfying long-term efficacy.

Objective     To evaluate the clinical effectiveness of valve-sparing aortic root replacement (VSARR) in the treatment of patients with dilated aortic root after operation for tetralogy of Fallot (TOF). Methods     A retrospective analysis was conducted on clinical data of TOF patients with aortic root dilation who underwent VSARR in our hospital from 2016 to 2022. Results     Finally 14 patients were collected, including 8 males and 6 females, with a median age of 22 years ranging from 12-48 years. Among them, 5 patients had severe aortic valve regurgitation, 4 moderate regurgitation, and 5 mild or no regurgitation. Six patients had sinus of valsalva dilation, and 8 significant dilation of the ascending aorta. One patient had residual shunt due to ventricular septal defect, and 9 severe pulmonary valve regurgitation. The David procedure was performed in 10 patients, Yacoub procedure in 2 patients, and Florida sleeve in 2 patients. There was no perioperative mortality in the group. The median follow-up time was 2.9 years (ranging from 0.4 to 6.0 years). One patient had mild aortic valve regurgitation, and the rest had minimal or no regurgitation. One patient had mild stenosis of the left ventricular outflow tract, and the rest patients had no obvious stenosis. Conclusion     VSARR is a satisfactory treatment for aortic root dilation in patients with TOF, with no significant increase in the incidence of left ventricular outflow tract stenosis or aortic regurgitation during mid-term follow-up.

As more and more people worldwide begin using Chinese herbs, authentication of these herbs becomes an increasingly critical, international problem. Mistakes, misidentification, or willful deception can cause illness and even death. Questionable authenticity with regard to Chinese herbs arises for a number of historical, geographical and nomenclatural reasons, which will be described in this paper. The current situation in the Hong Kong market and some suggestions for alleviating the problem are also discussed.

Objective     To exploring the effectiveness of perioperative application of new surgical clinical classification and staging for myasthenia gravis (MG) in reducing the incidence of postoperative myasthenic crisis (MC). Methods     The clinical data of patients with generalized MG admitted to the Comprehensive Treatment Center for Myasthenia Gravis of Henan Provincial People’s Hospital from January 2018 to June 2022 were retrospectively analyzed, who were scored with myasthenia gravis-activities of daily living (MG-ADL) score and quantification of the myasthenia gravis (QMG) score at the first visit, 1 day before surgery, and 3 days after surgery. The patients were divided into a group A (typeⅡ) and a group B (typeⅢ+Ⅳ+Ⅴ) by the new surgical clinical classification and staging of MG according to the disease progression process, and all patients underwent expanded thoracoscopic thymus (tumor) resection after medication and other interventions to control symptoms in remission or stability. The incidence of MC and the efficiency rate after surgery were analyzed. The normal distribution method and percentile method were used to calculate the unilateral 95% reference range of the QMG score and MG-ADL score. Results     Finally 126 patients were enrolled, including 62 males and 64 females, aged 13-71 years, with an average age of 46.00±13.00 years. There were 95 patients in the group A and 31 patients in the group B, and the differences of the preoperative baseline data between the two groups were not statistically significant (P>0.05). The incidence of postoperative MC was 1.05% (1/95) in the group A and 3.23%(1/31) in the group B (P>0.05). The effective one-sided 95% reference range of the QMG score and MG-ADL score 1 day before surgery was 0-7.75 and 0-5.00, and there was no postoperative death in both groups. Conclusion     The new surgical clinical classification and staging of MG can guide the timing of surgery, which can benefit patients undergoing surgery for MG and greatly reduce the incidence of postoperative MC.
