There are still many questions concerning the choice of tactics for the treatment of cholelithiasis in childhood. For a long time, cholelithiasis traditionally considered a pathology of adults. Accordingly, virtually all research was devoted to the diagnosis and treatment of this pathology in the above group of patients. Purpose of research. Justification of tactics in surgical treatment of cholelithiasis in children. Patients and research methods. The work formed observations on 135 children aged from 2 to 17 years with cholelithiasis. In 70.4% of cases the disease is observed in girls and boys, respectively at 29.6%. 7.8% of patients have children disease arose against the backdrop of hemolytic anemia. One patient, who received urgent indications, had manifestations of mechanical jaundice: an increase in the level of common bilirubin and its direct fraction, pronounced jaundice of the skin. In the second group, 140 children with chronic stoneless cholecystitis were compared. Research result. All patients with cholelithiasis identified different ways deformation in the area of gallbladder duct. One of the major causes of cholelithiasis in children are changes in the gallbladder duct. No patient has ever been found in concretions extrahepatic biliary passages. In patients with chronic stone-free cholecystitis pathology in the area of bladder flow was not found. Conclusion. One of the major causes of gallstone disease in children are changes in the gallbladder duct, that most likely leads to obstruction of outflow of bile from the gall bladder, with the subsequent formation of concrements. Therefore, the conduct of conservative treatment of cholelithiasis in children appear to be ineffective and the method of choice in the treatment of this pathology can be a cholecystectomy.

Purpose. This study aimed to improve the results of surgical treatment of children with hereditary autoimmune hemolytic anemia by laparoscopic splenectomy. Materials and methods. In the period from 1991 to 2020, a total 47 patients with hereditary autoimmune hemolytic anemia were treated in the surgical department of the Republican Childrens Clinical Hospital of Syktyvkar. Splenectomy was performed by the open method in 25 children, and laparoscopic method in 22 patients. Since 2019, the method of spleen reduction during laparoscopic splenectomy has been used in 3 patients when the large size of the mobilized spleen does not correspond to the size of the endoscopic container. Results. On average, surgical intervention using the above-described method of spleen reduction lasted for 19 2 min lesser than with laparoscopic splenectomy without the above method, due to the possibility of removing a significantly smaller volume of spleen tissue from the endoscopic sac outside the abdominal cavity. However, the most important achievement was the almost complete elimination of the risk of getting free fragments of a pathologically altered spleen with its possible replantation and recurrence of the clinic of autoimmune hemolytic anemia. The postoperative period was smooth, and all patients were discharged at their place of residence 7 days after the laparoscopic splenectomy. Intra-abdominal complications and relapses of the disease associated with the above-described method of operation did not occur in any patient within 612 months postoperative. Conclusion. The proposed method of spleen reduction during laparoscopic splenectomy made it possible to avoid relapses of the disease, reduce the operation time, as a result, improved the results of surgical treatment in children with hereditary autoimmune hemolytic anemia.

Introduction. The first publications about acute appendicitis in the conditions of the new COVID-19 coronavirus infection have appeared. Most authors point to the increased time of seeking medical help in such patients and an increase in the level of postoperative complications.Material and methods. A retrospective study of 192 case histories of patients aged 3 to 17 years with various forms of acute appendicitis who were treated in the surgical Department of the Republican children’s clinical hospital in the period from 2019 to November 2020 was conducted. Children operated on during 2019 before the start of the new coronavirus pandemic were included in the first group (n = 114). Children operated on in 2020 after the development of a new coronavirus pandemic were included in the second group (n = 78).Results. The age of patients in both groups compared did not differ significantly. The course of the disease was within the average accumulated indicators and the terms of hospitalization did not change significantly. According to our observations, the time of admission to the surgical hospital from the time of the disease in the pre-coronavirus period and during it also did not differ significantly, which indicates that the same availability of medical care remains even during the epidemic. Our study also showed that the number of requests for complicated appendicitis in children during the COVID-19 epidemic even decreased, which ultimately led to a decrease in the level of postoperative complications. The study did not establish a significant difference between the main results of treatment of children with acute appendicitis before and during the new COVID-19 coronavirus infection. Only the level of postoperative complications significantly decreased in patients operated during the COVID-19 epidemic, which is associated with a lower admission of children with complicated appendicitis.Conclusion. With the onset of the pandemic, the organization of medical care for the child population with acute pathology in the Komi Republic did not change and did not have any restrictions, which made it possible to maintain the timely provision of surgical care to children with acute appendicitis at the proper level.
