Objective To study the survey outcome of idiopathic scoliosis ( AIS) in 12 881 junior middle school students from Shantou city ,Guangdong province.Methods From October 2013 to January 2015,the survey of AIS was carried out in 12 881 junior middle school students from 10 middle schools in Shantou city ,Guangdong province.Three methods such as school screening ,hospital review and X -ray film examination were used.The two five surface checking method was used as physical examination method .X-ray was used to slicing a positive lateral view of the whole spine as standing position.The persons whose Cobb angles ≥10°were diagnosed as AIS.Results The amount of individual with suspicious signs were 1 543 students,the suspected rate was 11.98%.Meanwhile,a further checking was conducted by hospital to 263 students,the response rate was 17.04% and 136 students were diagnosed as AIS.The positive rate of AIS was 51.71%.Conclusion The prevalence of AIS in junior middle school students in Shantou city is higher than national average level.Therefore,it is necessary to attach attention to the census for AIS.

Objective    To explore the safety and feasibility of uni-portal video-assisted thoracic surgery (VATS) for the treatment of bronchopulmonary sequestration (BPS). Methods    The clinical data of BPS patients with surgical resection in Shanghai Pulmonary Hospital from February 2010 to June 2021 were reviewed. The patients were divided into a VATS group and a thoracotomy group according to the operation method. The operation time, intraoperative blood loss, hospital stay and postoperative complication rate were compared between the two groups. The VATS group was subdivided into a uni-portal VATS group and a multi-portal VATS group for subgroup analysis. Results    Finally 131 patients were enrolled, including 62 males and 69 females with an average age of 39.3±13.2 years. There were 103 patients in the VATS group and 28 patients in the thoracotomy group. A total of 104 patients were diagnosed with left lower BPS, 26 with right lower BPS and 1 with bilateral lower BPS. The main symptom was cough (88 patients, 67.2%). There were 119 patients diagnosed by thoracic enhanced CT before operation. Compared with the thoracotomy group, the operation time was not statistically different (P=0.717), but the blood loss was less, the rate of postoperative complication was lower and hospital stay was shorter in the VATS group (P<0.05). The rate of conversion to open surgery in the uni-portal VATS group and multi-portal VATS group was 11.8% and 13.5%, respectively. Meanwhile, patients in the uni-portal VATS group had shorter operation time and postoperative hospital stay, less blood loss and lower postoperative complication rate than those in the multi-portal VATS group (P<0.05). Conclusion     In order to improve the rate of diagnosis, the lung enhanced CT scan should be selected as an optimal noninvasive method in adult suspected patients (especially those with solid cystic and solid lesions in the lower lobe). Uni-portal VATS is a safe and feasible method for BPS which can be widely promoted.
