Research has been carried out on the use of the symbiotic “Rumimaster” in balanced diets of highly productive cows in the conditions of the breeding plant “Kirovskaya meadow-bog experimental station”. The experiment was carried out on two groups of animals in the middle of lactation with a duration of 90 days. The inclusion of the feed additive “Rumimaster” in the diet of experienced cows contributed to an increase in the gross production of natural and 4% fat milk by 124.5 kg and 128.4 kg, the yield of milk fat and milk protein by 5.2 and 4.1 kg, respectively. … The differences between the groups for these parameters were in the range of 5.1-5.7%. The productivity of cows for 305 days of lactation in the experimental group was higher than in the control by 7.5%. The symbiotic “Rumimaster” promoted the activation of digestion processes, which was reflected in the increase in the time of feed consumption and the duration of the chewing gum. The cows of the experimental group showed an increase in the level of digestibility of the main nutrients. In terms of the digestibility of crude protein and crude fiber, the experimental group of cows significantly exceeded the indicators of the control group by 3.3 and 3 absolute percent, respectively. The blood biochemical parameters of the animals of the experimental and control groups were within the physiological norm. The economic evaluation of the research results showed the effectiveness of the use of the symbiotic “Rumimaster” in the diets of lactating cows, which was expressed in the receipt of additional profit from one cow in the amount of 1,344.79 rubles for the period of experience and an increase in the profitability of milk production by 2.1 absolute percent.
Применение имплантов в коррекции диафрагмальной грыжи у новорожденныхThe use of implants for surgical treatment of congenital diaphragmatic hernia in newborns Врожденная диафрагмальная грыжа (ВДГ) -патология, которая требует обязательной хирургической коррек-ции. При значительных дефектах диафрагмы, например аплазии ее купола, зачастую возникает необходимость в использовании имплантационных материалов. До сих пор нет единой точки зрения по вопросу выбора имплан-та. В статье представлены результаты сравнительного анализа лечения новорожденных (n = 40) с левосторонней ложной ВДГ. Всем пациентам была выполнена торакоскопическая пластика купола дифрагмы. По типу использо-ванного имплантационного материала детей разделили на две группы: для первой (n = 16) применяли синтетичес-кие импланты «Экофлон» («НПК "Экофлон"», Россия), для второй (n = 24) -биологические импланты Permacol (Tissue Science Laboratories, Великобритания). Результаты исследования показали преимущества биологичес-кого импланта: время операции при его использовании было меньше (106 мин против 144 мин при использова-нии «Экофлона», p <0,05); число рецидивов -также меньше (28 % против 54 %, однако p >0,05); случаев от-торжения импланта не было (при использовании «Экофлона» у двух пациентов началось воспаление, p <0,05).Congenital diaphragmatic hernia (CDH) is an absolute indication for surgical treatment. In case of extensive defects of the diaphragm, such as diaphragmatic aplasia, the use of implants is required. So far, there is no unanimous opinion on the type of the implant. The article presents a comparative analysis of treatment of 40 newborns with left pseuso-CDH. All patients received thoracoscopic repair of the diaphragmatic cupula. The patients were divided into two groups according to the type of the implant: 16 newborns received Ecoflon synthetic implants (Ecoflon Scientific and Production Complex, Russia) and 24 newborns received Permacol biologic implants (Tissue Science Laboratories, UK). The study demonstrated the advantage of the biologic implant over the synthetic one: the surgery took less time (106 minutes compared to 144 minutes with Ecoflon, p <0.05); relapses were also more rare (28 % and 54 %, respectively; however, p was >0.05); no implant rejection was observed (with Ecoflon, two patients responded with inflammation, p <0.05).Ключевые слова: новорожденные, врожденная диафрагмальная грыжа, торакоскопия, имплант, имплантационный материал, «Экофлон», Permacol

Purpose. Presentation of clinical cases of rare combination of omphalocele with pylorostenosis in the postoperative period and additional liver lobe. Materials and methods. In National Medical Research Center for Childrens Health of health surgical ward of newborns and infants for the 2019 us operated 2 children who performed surgery involving intra-operative decision making about further surgical tactics. Results. the results of surgical treatment of newborns with omphalocele combined with hypertrophic pylorostenosis and extra liver lobe are presented. Conclusions. In patients with malformations of the anterior abdominal wall in the postoperative period, when regurgitation syndrome appears, it is necessary to make a differential diagnosis between the functional and organic causes of obstruction. When confirming the organic nature of the obstruction, surgical intervention is indicated. It is necessary to be able to timely and objectively assess the risks and expediency of the approach when choosing surgical tactics in each individual case.
Anorectoplasty and pull-through procedure can be performed with extended mobilization or tension anastomosis, which can compromise the vasculature of the rectum. We aimed to analyze the histopathological ndings, hypoxia biomarker values and to correlate the incidence of anal stenosis and defecation disorders of both conditions in experimental models. MethodsWe created anorectal reconstruction models during anorectal mobilization with extended mobilization with impaired vascularization (group I) and tension anastomosis (group II) in rats. Hypoxia biomarker values was assessed in both groups and in sham operated animals (group III). The histopathological changes on the 3 rd postoperative day, anal stenosis and defecation disorders on the 35 th day are compared with each other and with a control group (group IV). ResultsHypoxia biomarker levels con rmed postoperative ischemia in I -III groups compared to the control.Groups I, II are accompanied by pronounced histopathological changes in the anorectum on the 3rd postoperative day and accompanied by severe brosis on the 35 th day. In comparison to group III, both groups showed defecation disorders and anal stenoses. ConclusionExtensive mobilization with vascular impairment and tension anastomosis resulted in similar ischemia with histopathologic changes, which in the long term resulted in brotic changes associated with defecation disorders.
BACKGROUND: The preserved cloaca is a particular type of anorectal anomaly. The combination of urological, genital, and rectal abnormalities makes radical reconstruction difficult. MATERIALS AND METHODS: This study examined operations performed in 50 patients with persistent cloaca treated from 2010 to 2021. Two groups are presented: the first with 35 children and a short canal (3 cm), and the second with 15 children and a long canal (3 cm). We examined the prognosis for bowel control, the type of operation, the need for vaginal reconstruction, complications after surgery, and the days of hospital stay. RESULTS: Anomalies of the Mllerian ducts in the second group (94%) were higher than in the first (36%) (p 0.001). The sacral index and myelodysplasia did not differ in both groups. The sacral index in the first group was 0.62 0.14, and in the second group, it was 0.58 0.14 (p = 0.520). Myelodysplasia in the first group was 33%, and in the second group, it was 38% (p = 0.744). Total urogenital mobilization (51%) was used in the first group, and abdominal reconstruction (54%) was used in the second group. Vaginal reconstruction was required in 28% of patients in the first group and 60% in the second group. Complications were 3.5 times more likely in the first group (60% versus 17% in the second) (p = 0.003). The length of hospital stay in patients in the second group was longer than that of patients in the first group. CONCLUSION: Our study data demonstrate that the reconstruction of a persistent cloaca requires individual planning of the operation, considering the length of the canal and the state of all structures forming the cloaca.
Introduction. Malformations of the anterior abdominal wall in newborns is one of the actual problems in neonatal surgery. Antenatal diagnostics of such defects as omphalocele and gastroschisis allows to diagnose and perform necessary surgical interventions in time. Often, outcomes of treatment of newborns with embryonic hernia depend not only on the form of the defect, but also on the accompanying abnomalies. Purpose. To present outcomes of surgical treatment of newborns with anterior abdominal wall malformations. Material and methods. From December 2017 till May 2019, 34 pregnant women with fetal anterior abdominal wall malformations were consulted; 17 out of them with omphalocele and gastroschisis were treated. Results. In December 2017, the surgical department for newborns and infants at the National Medical Research Center for Children’s Health successfully helped children with malformations of the anterior abdominal wall. 16 children were discharged home in a satisfactory condition; there was one unsatisfactory outcome. 11 patients were treated for gastroschisis; 6 patients were treated for omphalocele. 3 patients had repeated surgeries for concomitant pathologies. There were no any adhesive processes and commissural intestinal obstruction. Conclusions. In Russia, there are two groups of newborns with anterior abdominal wall defects: children with isolated defects and children with concomitant pathologies who have an increased risk of unsatisfactory outcomes. The technique developed by us for treating newborns with anterior abdominal wall malformations and concomitant pathologies has very good cosmetic and functional results and reduces the number of postoperative complications and unsatisfactory outcomes.
Intestinal atresia is a congenital obstruction of the lumen of the jejunum or ileum and is one of the most common causes of congenital obstruction in newborns. This literature review is devoted to the surgical treatment of newborns with various types intestinal atresia. Causes of intestinal atresia are considered, where a special role is assigned to the genetic theory, the expression of the nucleotide sequences ITGA2 873G/A and NPPA 2238T/C and antenatal circulatory disorders of the developing intestine. Topographical-anatomical and morphological characteristics of the intestine in newborns with intestinal atresia are studied in detail in articles. A table of revealed histomorphological features of the small intestine in children with atresia was compiled. In addition, processes occurring in the mucosa, submucosa, muscle, and serous membranes are described in detail. A relationship was found related to the size of the atresia site and duration of ischemia. The theory of neuromuscular regulation of the intestine is considered, in which an important role is assigned to interstitial pacemaker cells of Cajal. Variants of anastomosis depending on the difference in diameters of the adductor and excretory parts of the intestine are analyzed, and results of treatment in patients with laparoscopic access are described. The postoperative course of disease, development of complications, recurrent operative interventions, duration of parenteral nutrition, and onset of enteral load was evaluated. Conclusion. The choice of surgical technologies used to restore the patency of the intestinal tube is determined by the degree of discrepancy between diameters of anastomosed segments. The prognosis is not determined by tactics of surgical treatment, type of atresia, time before treatment, and presence of associated anomalies.
