Introduction: Recently, the use of thoracoscopic methods in spinal deformity surgery has increased, however, the issue of the effectiveness of combining anterior release with posterior spinal fusion compared to single-stage posterior instrumentation remains controversial, which raises the issue of the effectiveness and feasibility of their use., Purpose: To evaluate the effectiveness of endoscopic anterior release for thoracic scoliosis in children., Material and Method: A retrospective analysis of the results of surgical treatment of 48 patients with idiopathic scoliosis of the thoracic spine aged 12-17 years, with a thoracic curve of more than 60°, was carried out. To determine the stability of deformity, the stability index according to A.I. Kazmin was used. (SI) defined as the ratio of the angle of deformity in the supine position to the angle of deformity in the standing position. Indications for anterior release were incomplete skeletal growth and relatively stable deformities (SI 0.75-0.85). Group 1 included 27 patients operated on in one stage without anterior release, and group 2 included 21 patients in two stages, with preliminary anterior release using video-assisted thoracoscopy., Results: In group 1, the average Cobb angle of deformity was 71.8° with an average stability index of 0.8. In the second group, the average cobb angle of deformity was 69.7°, the average stability index was 0.82. In group 1 after surgery, the average Cobb angle was 27.8°, with an average correction of 63.39%. In the second group, the postoperative deformity angle was 17.4°, the average correction was 76.26%. Thus, we found a statistically significant increase in postoperative correction when using a combined anterior/posterior approach (p < 0.05)., Conclusion: In the study, in patients with relatively stable deformities, a statistically significant increase in the degree of postoperative correction was revealed (p < 0.05) when using a combined anterior/posterior approach. Performing an anterior thoracoscopic release for thoracic deformities can improve long-term results due to the formation of 360° spinal fusion at the apex of the deformity, as well as turning off the pathogenetic links in the progression of the deformity., Level of Evidence: III., Competing Interests: Conflicts of interest The authors have none to declare., (Copyright © 2024 Elsevier Inc.

Objectives: The objective of this work was to develop technology to create 'soft' patient-specific models of semilunar heart valves, the aortic valve in particular, suitable for training and simulation of surgical and endovascular interventions., Methods: Data obtained during routine cardiac contrast-enhanced multislice computed tomography were used to create 3-dimensional models of the aortic root. Three-dimensional models were used to create soft silicone models of the aortic root made by casting silicone into a negative mould printed with stereolithography. A comparison between the constructed models and the size of the aortic root was performed. We quantified how much time was needed for production of each model., Results: Four patient-specific soft models of the aortic root were produced. Data from patients of different ages and body surface areas were used as prototypes. All models had minimum size errors. During development of this technology, production time per model was reduced from 63 to 39 h., Conclusions: We have demonstrated the feasibility of making soft patient-specific 3-dimensional aortic root models using currently available technology. These models can be used both for training physicians in a variety of open surgical and endovascular interventions and for the study of complex aortic root geometry., (© The Author(s) 2020.

Aim: To improve treatment results of children undergoing laparoscopic genitourinary surgery by optimizing intraoperative hemostasis., Materials and Methods: The study comprised 110 children with various genitourinary diseases. The study group included 70 children who underwent laparoscopic surgery with optimized hemostasis with the use of an automated electrosurgical vessels ligation device LigaSure. Forty children who received standard intraoperative hemostasis with mono- or bipolar coagulation made up a control group., Results: The operative time was significantly shorter with the optimized method of hemostasis than when using mono- and bipolar coagulation [77.02 min versus 112.5 min (p<0.05)]. The blood loss in the study group was also significantly lower than in the control group [17.9 and 34.2 ml, respectively (p<0.05)] due to precise control and final hemostasis. There were no intraoperative complications and conversion to open surgery in patients in the optimized hemostasis group, whereas in the control group two complications were observed., Conclusion: Laparoscopic urogenital surgery with the optimized hemostasis using the automated electrosurgical vessels ligation device LigaSure in children is optimal due to the minimal injury to the coagulated tissues, the ability to forgo clipping and ligation of the vessels, which results in shorter operative time and reduced intraoperative blood loss.

The prevalence of various kidney diseases in children remains high in recent decades. Adequate nutrition management can enhance the effectiveness of drug treatment, slow the frequency of relapses andprevent the progression of the disease. The article is devoted to modern approaches to diet therapy in various kidney diseases in children with the defeat of tubular and glomerular appa ratus. For the first time the therapeutic diets for children with various kidney diseases are presented. Particular attention is paid to diet therapy in nephrotic syndrome (steroid-responsive and steroid-refractory). Dietary approaches with modern formulas for enteral nutrition in cases of steroid therapy complications in children with renal insufficiency (in predialysis stage and on dialysis) are described. Differentiated nutritional approaches for patients with different types of crystalluria are separately presented.
