[Training curves for endosurgical interventions in neonates and infants].

AIM: To demonstrate training curves for endosurgical interventions in neonates and infants. MATERIAL AND METHODS: It was analyzed duration of thoracoscopic reconstruction of esophageal atresia (31 patients) and laparoscopic Nissen fundoplication (61 patients) performed for the period from January 2005 to December 2012. Graphs and tables reflecting correlation between duration and number of operations were framed. RESULTS: Figures demonstrate reducing duration of surgery with increase of endosurgical interventions number. CONCLUSION: Our data revealed that time necessary for minimally invasive procedures in infants and neonates decreases in process of experience accumulation.

[Vacuum-therapy for complicated anterior abdominal wall wounds and intestinal fistulas in children].

AIM: To present results of VAC application in children with complicated wounds of anterior abdominal wall combined with intestinal and/or biliary fistulas. MATERIAL AND METHODS: For the last 7 years 8 patients aged from 1.5 months to 15 years with infected postoperative wounds of anterior abdominal wall complicated by intestinal fistulas (6), biliary and intestinal fistulas (1) and biliary fistula (1) have been treated at the surgical department №2 of Russian Children's Clinical Hospital. All patients received complex medical therapy and local VAC-therapy. RESULTS: Granulation and wound's size reduction were observed within first 7 days of VAC-therapy application in 5 (62.5%) children. In 4 (50%) patients at least 1 intestinal fistula has been closed in 15 days after VAC-therapy initiation on the average (range 7--24). Closure of all fistulas and wounds healing were observed in all patients in 28 days (range 16--42) after VAC-therapy initiation on the average. CONCLUSION: VAC-therapy is safe and effective treatment of complicated wounds of anterior abdominal wall combined with intestinal and/or biliary fistulas in children.

[Sliding traсheal plasty in children under extracorporeal membrane oxygenation (first experience in Russia)].

AIM: To improve the results of surgical treatment of children with extended tracheal stenosis. MATERIAL AND METHODS: Since 2013 slidingtraсheal plasty under extracorporeal membrane oxygenation was performed in 4 children aged 1 year 2 months - 4.5 years with extended tracheal stenosis in Children's City Clinical Hospital №13. Patients' weight was from 10,5 to 16 kg. Extended tracheal stenosis and complete cartilag inousrings were confirmed in all patients after peoperative survey. Indications for surgery were based on medical history data, the severity of respiratory failure and survey data. Sliding traсheal plasty by different approach esunder extracorporeal membrane oxygenation was applied in all patients. RESULTS: There were no intraoperative complications. In the study group 1 patient died in remote postoperative period after discharge due to deterioration of his condition caused by upper respiratory tract infection and acute respiratory failure. In immediate postoperative period 1 patient had pronounced growth of granulation tissue in the area of anastomosis followed laser photocoagulation and prolonged intubation. The average ICU-stay was 24 days, the duration of mechanical ventilation - 11 days. Follow-up carefor patients was conducted on terms of 4-6 and 12 months after surgery. In 2 patients moderate complaints of recurrent bronchitis without signs of respiratory insufficiency during 6-8 months postoperatively were observed. In one child complaints were completely absent.

[Thoracoscopic lung resection in children].

The spectrum of pulmonary surgical pathology in newborns and infants is mainly presented by congenital diseases. Surgery is the main radical method of treatment of children with congenital lung diseases. By this time in the N.F.Filatov City Children's Hospital No13 it is performed more than 1000 endoscopic operations on the thoracic cavity including more than 300 lung resections. More than 190 cases were caused by congenital lung disease. The results of treatment of 194 infants with congenital lung disease for the period 2005-2014 are analyzed in this article. 14 (22%) patients were operated urgently. 8 patients (12%) with compensated respiratory failure underwent surgery at the age of 8 to 46 days. Children with absence of clinical manifestations underwent thoracoscopic lung resection at the age of 3 to 8 months. Thoracoscopic lobectomy was performed in the 40 cases (62%). There were no intraoperative complications. Thoracoscopic lung resection for malformations in newborns and infants is currently the method of choice. It allows to visualize pathological focus intraoperatively and to perform precise dissection of pulmonary root structures using modern equipment. Thus, it improves course of postoperative period and reduces duration of hospital-stay. Repeated lung resection in patients with recurrent tuberculosis of operated lung (literature review and own data).

[Endosurgical treatment of the bile duct lesions in children].

UNLABELLED: Question of feasibility of laparoscopic Kasai procedure and laparoscopic hepaticojejunostomy for biliary atresia (the BA) and choledochal cysts (the CC) in children has been a subject of discussion for a long time and still remains unsolved. AIM: To improve the results of surgery for biliary tract malformations (the BTM) in children using laparoscopic technique. MATERIALS AND METHODS: The are 55 patients with BA and CC, who were performed endosurgical operations, and 37 patients, who were performed traditional open surgical procedures. During this study we worked out and put into laparoscopic practice some new methods. We've made an analysis of technical features of liver transplantation after laparoscopic and traditional Kasai's operation in BA. RESULTS: The duration of laparoscopic Kasai procedure was significantly longer than open surgery (p < 0.05). In CC the duration was the similar (p > 0.05). There was no any urgent surgical complication after laparoscopic Kasai procedure in contrast to open surgery. We observed significantly fewer complications (40%) after laparoscopic hepaticojejunostomy than after traditional hepaticojejunoduodenostomy (84.6%, p < 0.05). The average length of stay in ICU and duration of analgesia after laparoscopy was significantly lower than after open surgery (p < 0.05). Comparing the efficiency of endosurgery and traditional operations using coloration of stool, decreasing of bilirubin level and the presence of indications to liver transplantation criteria we didn't find any significant difference (p > 0.05). CONCLUSION: At the same efficiency of laparoscopic and open reconstructive surgery for BA and CC the first has a number of incontrovertible advantages. Our experience allows us to recommend laparoscopic procedures to perform for the correction of BTM in children.

[The accessibility of high-tech medical care of newborns with surgical pathology in conditions of Far North].

The actual stage of development of public health rendering of specialized medical care is based on principles of generality, accessibility, addressness, qualitativeness, and effectiveness. However, the problem of rendering specialized medical care to population is one of most critical targets in district centers and requires immediate solution. The main mean of resolving this problem is re-hospitalization of patient in more large-scale medical institutions. The rendering of high-tech medical care, surgery care included, to newborns in the Republic of Sakha (Yakutia) is possible only in conditions of metropolitan health institutions i.e. medical institutions of third level. Annually, almost half of newborns with surgical pathology is transported from central district hospital. The organization of reanimation counseling center, maintenance of remote monitoring of newborns and development of telemedicine and means of sanitary aviation play main role in supporting accessibility of high-tech medical care in conditions of this region.

[The choice of surgical access in the treatment of lung hydatidosis in children].

Thoracoscopic and traditional access for the treatment of lung hydatidosis in children was compared. 56 children, who composed the 1st (control) group, were operated on with the open access. The 2nd (main) group, consisted of 22 patients, operated on thoracoscopically. The issue holds the thorough description of the operative technique. The mean operative time was 61.2±7.4 min for the thoracoscopic operation, the mean pleural drainig time was 2.5±0.7 days. The mean postoperative hospital stay was 12±3.5 days. For the patients of the control group, the operative time was 86.4±25.2 min, draining time was 4±1.2 days and hospital stay was 18.4±8.2 days. There were no conversion cases. 3 patients of the "thoracoscopic" group developed postoperative pneumonia and bronchial fistula. Considering the strict following the principles of antiparasitic treatment, the endoscopic treatment of lung hydatidosis proved to be a method of choice for the surgical treatment of lung hydatidosis in children.

[Thoracoscopic thymectomy in children by myasthenia gravis].

The authors' experience of surgical treatment of myasthenia gravis in children was analyzed. 32 patients were operated on, mean age was 13±3 (5-21 years); girls were 26, boys were 6 (19%). Disease severity was IIB-IVB by the MGFA classification, all patients were on anticholinesterase and pednisolone therapy. The operation was indicated by certified neurologists, specialized in myasthenia. All patient were thoracoscopically thymectomized using left- or rightside access. There were no conversions and intraoperative complications. The operation duration was 77±23 min. The postoperative hospital stay was 6.6±3.6 (3-9) days. Excellent long-term results were achieved in 6 (25%) patients, good - in 20 (62.5%) children, no changes were registered in 2 and deterioration of myasthenia in 2 (6.25%) patients. The study proved that thoracoscopic thymectomy obtains the radicalism of open technique, proposing the easier postoperative period and being the method of choice for the surgical treatment of myasthenia gravis in children.

[Use of venovenous extracorporeal membrane oxygenation in 14 months old child with acute respiratory distress syndrome and pneumonia].

UNLABELLED: Extracorporeal life support (ECLS) is used in pediatric patients with ARDS in recent 20 years with survival rate from 50 to 67% Venovenous ECLS was used in 1 year 2 months old patient with ARDS and pneumonia developed in postoperative period after gastral esophagoplasty. Purposes of ECLS use were stabilization child's condition and normalization of gas composition of blood with relative lungs repose. Indications for ECLS were increasing respiratory failure, hypoxemia, low respiratory index (PaO2/FiO2 ratio 47.3), alveolar-arterial gradient of oxygen (A-aDO) 630 mmHg and absence of positive effect from high frequency oscillation (HFO). MATERIALS AND METHODS: ECLS was used in 1 year 2 months old patient with ARDS and bilateral pneumonia developed in postoperative period after gastral esophagoplasty. Deltasteam system (Medos Medizintechnik AG, Germany) with centrifugal pump and servoregulation of blood flow pressure was used for ECLS. Double-lumen cannula with size 12 French was used ECLS was instituted via right internal jugular vein. RESULTS: The patient did not have expressed heart failure. Thus preference was given to venovenous ECLS and not to venoarterial ECLS. Duration of ECLS use was 72 hours. Auscultation parameters and gas exchange improved haemodynamics stabilized parameters of biochemical and haematological analysis normalized and the dynamics x-ray examination was positive after the ECLS use. Patient was decannulated and extubated. CONCLUSIONS: Venovenous ECLS was an only way of life support in child with heavy ARDS and pneumonia developed in postoperative period More observations are needed for more thorough analysis and recommendations.

[Early results of thoracoscopic treatment of inborn and acquired lung diseases in children].

Thoracoscopic and traditional methods of treatment of the inborn and acquired lung diseases in children were comparatively analyzed. The main group, operated on thoracoscopically, consisted of 30 patients. The control group, operated on thoracotomically, consisted of the same number of children. Both groups were comparable to the age, gender, diagnostic algorithm, risk and preoperative prepare. Traumaticity of the operation and postoperative period were assessed. Thoracoscopic method proved to have indisputable advantages.

[The magnetic foreign bodies of the gastrointestinal tract in children].

The authors own the experience of treatment of 23 children with magnetic foreign bodies (MFB) of the gastrointestinal tract. They share the possibilities of diagnostics and surgical treatment of children on the vivid clinical examples. By MFB in the stomach, which do not leave the gastrointestinal tract naturally, the use of fibroesophagoduodenoscopy is recommended. The laparoscopy is helpful in case of the uncomplicated MFB in the intestine. The X-ray control of the complete foreign bodies evacuation is necessary.

[Treatment of bronchiectasis in children].

The thoracoscopic and traditional thoracotomic surgical access for bronchiectesis treatment in children were compared. The first (thoracoscopic) group included 18 children. The control (thoracotomic) group included 26 patients. The mean operative time in the 1st group was 78.3±31 min; pleural draining lasted for 1.3 days and postoperative hospital stay was 9.93±2.08 days. The mean operative time in the 2nd group was 81.7±35.1 min; pleural draining lasted for 3.3 days and postoperative hospital stay was 14.4±3.4 days. Conversion was needed in 4 cases. Therefor, the thoracoscopic surgery proved to be much more preferable in children because of its' minimal invasiveness.

[The treatment of chemical burns of the esophagus in children].

The article covers the 22-year experience of treatment of chemical burns of the esophagus in 4252 children. The cicatrical stricture (the III degree burn) of the esophagus had 5.9% of patients. 82% of all patients were aged 1-3 years. The endoscopic signs of esophageal burns, developed in clinic, allow the thorough differentiation of burn stages, which has certain influence on treatment strategy. Treatment strategies, depending on the stage of esophageal burn and chemical agent, were described. Methods and terms of gullet bougienage were analyzed.

[The surgical correction of vascular tracheal rings in children].

The aortic arch and its branches anomalia compound 1-3.8% of all vessel inborn diseases. The treatment of such anomalia as tracheal vessel ring aims the liquidation of esophageal and tracheal compression. The authors introduce their experience of thoracoscopic tracheal vessel rings resection in 6 children. The time of the operation was 145±15min. There were no conversions to the traditional open surgery. The result was excellent in 4 of 6 children, who were completely releaed of tracheal obstruction symptoms. The rest 2 children demonstrated mild respiratory symptoms, cuased by the tracheomalation.

[The endoscopic operations by solid thoracic tumors in children].

20 patients were operated thoracoscopically on the cause of the solid tumors of the pleural cavity. Patients were aged from 1 day of life to 17 years. Minimal size of the tumor was 3.1×3.5×4.0 sm; maximal 10×10×20 sm. The control group was created of 22 children with thoracic tumors, operated via thoracotomy. The postoperative period and outcomes were statistically better among patients, treated thoracoscopically.
