[Choledochal cysts: surgical treatment in newborns and infants]. / Kisty kholedokha: osobennosti khirurgicheskogo lecheniya u detei pervykh trekh mesyatsev zhizni.

OBJECTIVE: To improve postoperative outcomes in newborns and infants with choledochal cysts and to determine the indications for surgery. MATERIAL AND METHODS: There were 13 children aged 0-3 months with choledochal cyst who underwent reconstructive surgery between 2019 and 2023. In all children, choledochal cyst was associated with cholestasis. Acholic stool was observed in almost half of the group (n=7). All children underwent cyst resection and Roux-en-Y hepaticoenterostomy. RESULTS: Symptoms of cholestasis regressed in all patients. Mean surgery time was 128±27 min. There were no complications. Enteral feeding was started after 1-2 postoperative days, abdominal drainage was removed after 6.2±1.6 days. Mean length of hospital-stay was 16±3.7 days. Adequate bile outflow is one of the main principles. For this purpose, anastomosis with intact tissues of hepatic duct should be as wide as possible. Roux-en-Y loop should be at least 40-60 cm to prevent postoperative cholangitis. CONCLUSION: Drug-resistant cholestasis syndrome and complicated choledochal cysts (cyst rupture, bile peritonitis) are indications for surgical treatment in newborns and infants. When forming Roux-en-Y hepaticoenterostomy, surgeon should totally excise abnormal tissues of the biliary tract to prevent delayed malignant transformation.

[The endotoxine aggression in the pathogenesis of postoperative complications in children with Hirsprung disease].

Signs of disseminated intravascular clotting (DIC), which were considered the laboratory sign of the subcompensated endotoxine aggression, were detected in 20 children with the Hirsprung disease, aged 3 months - 11 years. Under the influence of the operation stress the subcompensated DIC transformed to the acute decompensated reaction, which led to early complications, such as anastomosistis with tendency to the insufficiency or stenosis, enterocolitis, etc. The study revealed not only the straight connection between the postoperative complications and endotoxine aggression, but the necessity of preoperative preparation, directed on the decrease of the intestinal endotoxin level and normalization of antiendotoxin immunity.

[Laparoscopic heminephrouretherectomy in children with double kidney].

The article revises the first experienced of laparoscopic geminephrouretherectomy in our country. 5 children aged 3-14 years were operated on. In 1 case of double ureter the laparoscopic ureterectomy was performed, the rest 4 patients experienced geminephrouretherectomy (2 left and 2 right).The operative time was 100-180 minutes. There were no intra- and postoperative complications. All children were discharged on 6-12th postoperative day. Follow-up examination verified perfect cosmetic and functional results.

[Laparoscopic operation for Hirschsprung's disease in children].

Experience in the treatment of 5 children aged 6 months to 14 years with different types of aganglionosis of the colon using laparoscopic endorectal bringing down of the colon (like Coabe surgery) is analyzed. In all the cases this method permitted mobilization and resection of the intestine (to 60 cm), bringing down intact intestine on the perineum with simultaneous coloanal anastomosis. Duration of the surgery ranged from 120 to 240 min, postoperative hospital stay did not exceed 8 days. Functional and cosmetic results were excellent. The method is characterized by combination of advantages of classical Coabe operation with minimal surgical trauma of laparoscopic mobilization of the colon.

[Use of a laryngeal mask during combined regional anesthesia in children].

For intraoperative anesthesia, the authors applied central regional blocks. A laryngeal mask was used to maintain free airways patency. The purpose of this study was to provide evidence for the effectiveness of a laryngeal mask used under combined regional anesthesia and to establish whether the mask could be employed for artificial ventilation during laparoscopy in children.
