Methods: From March 2020 to March 2023, 100 inpatients with DS were classified into groups A, B, C, and D based on the CARDS classification system. Preoperative radiological data were analyzed to measure the severity of central canal stenosis, facet joint arthropathy, intervertebral disc herniation, and spinal epidural lipomatosis, osteophyte formation, range of motion (ROM), and computed tomography value of the vertebral bodies. The radiological characteristics and clinical contraindications for OLIF were compared among the groups. Results: Of the 100 patients, 51% had clinical contraindications for OLIF, which included 85%, 25%, 62.5%, and 20% of patients in groups A, B, C, and D, respectively. Compared with group B, group A demonstrated greater severity of central canal stenosis, whereas group C showed a higher degree of facet joint arthropathy. More patients in groups A and C had severe central canal stenosis. Regarding the ROM results, group A had segmental stiffness, whereas group D presented relatively unstable slip segments. Conclusions Patients with different DS subtypes have varied radiological characteristics. Groups B and D are suitable candidates for OLIF. Most patients in group A are unsuitable for OLIF because of bony hyperplasia, severe spinal stenosis, and segmental stiffness.

Objective To investigate the feasibility of retroperitoneoscopy in the treatment of adrenal masses in infants under 6 months old.Methods From January 2020 to November 2023,retroperitoneoscopic surgery was performed in 5 infants under 6 months old with adrenal tumors.Their age was from 1 month and 18 days to 4 months and 27 days,and their body weight was 5-8 kg.The lesion was found by prenatal ultrasonography in 1 case and by abdominal ultrasonography for other reasons after birth in 4 cases.Ultrasound and CT indicated a diameter of 1.7-5.5 cm for the adrenal masses.Results The operations of adrenalectomy and tumor resection were completed under retroperitoneoscopy.The operative time was 65-135 min(median,94 min).The intraoperative blood loss was less than 10 ml.The postoperative drainage tube retention time was 3-6 d(median,5 d).Pathological diagnosis showed 4 cases of adrenal neuroblastoma and 1 case of adrenal hyperplasia.Follow-ups for 1-36 months(median,3 months)with abdominal ultrasound and CT scanning showed no recurrence or metastasis.Conclusion Retroperitoneoscopy is relatively safe for the treatment of adrenal tumors in infants under 6 months old(tumors with acceptable boundaries).

Objective To summarize the clinical experience of thoracoscopic treatment of anterior mediastinal enterogenous cysts.Methods From July 2019 to July 2023,27 children diagnosed as having anterior mediastinal enterogenous cysts were treated with total thoracoscopic surgery through the lateral thoracic approach(three port method)in our department.The patients were placed in a healthy lateral position.The observation hole was located in the 5th intercostal space under the scapula,and the other 2 operating holes were established based on the location of the lesion and the endoscopic diamond-shaped method,both of which were 5 mm trocars.The CO2 pneumothorax was established at a pressure of 6 mm Hg.The visceral pleura of the cyst was opened with an electric hook,the cyst was fixed and pulled by intestinal forceps,and the cyst was completely removed by forceps and electric hook separation alternately.Results No conversion to thoracotomy was required.Complete resection was performed in 26 cases,and residual cyst wall existed in 1 case.Esophageal muscular layer was opened in 9 cases.During the operation,cysts obstructed the surgical field of view in 5 cases,which was not conducive to observation.The cyst puncture and fluid extraction were performed.The operation time was 45-120 min(median,70 min).The amount of blood loss was 3-10 ml(median,5 ml).Postoperative hospitalization lasted for 2-5 d(median,3d).The 27 cases were followed up for 1-43 months(median,22 months),and there was no recurrence.The compressed trachea in 2 cases was all recovered,with emphysema fully recovered.Conclusions Thoracoscopic treatment of anterior mediastinal enterogenous cysts in children is safe and feasible.When the surrounding structure of the lesion is complex,it can be combined with bronchoscopic or gastroscopic surgery if necessary.

Objective:To explore the impact and cost-effectiveness of community stroke screening intervention mode on stroke risk.Methods:A total of 3 561 community people over 40 years old who participated in screening intervention in 2017,2019 and 2021 were selected as research objects,and stroke risk was divided into low risk,medium risk and high risk.A Markov model was established to explore the impact of screening intervention mode on stroke risk in community population.The cost increment during the phase I trial was calculated,and the life year increment was adjusted according to the quality estimate of previous studies.The cost-effectiveness increment ratio was calculated,and the screening intervention mode was evaluated,and univariate sensitivity analysis was performed.Results:Within a certain range,intervention screening could effectively shift the status of residents to the low-risk direction,and finally stabilize the distribution of low-risk,medium-risk and high-risk were 47.4％,31.0％and 21.6％.The incremental cost of interventional screening was 160 245 yuan,the incremental quality-adjusted life year was 151.129 yuan,and the incremental cost-effectiveness ratio(ICER)was 1 060.319 yuan/QALY,which was less than 1 times the per capita GDP.The intervention program was fully cost-effective.Conclusion:Screening intervention can promote the transformation of the commu-nity population to a low-risk state of stroke in the prevention stage,and this approach has good cost-effectiveness performance.It is recommended that the primary medical and health institutions that are not enough to fully implement the integrated process ser-vice of community prevention and treatment of stroke should first implement low-cost screening intervention.
