[Integration of ICG-fluorescence cholangiography into the safety system of laparoscopic cholecystectomy].

The Aim Of The Study: Is evaluating the possibility of integrating ICG-fluorescent cholangiography into the general safety system for laparoscopic cholecystectomy to prevent damage to the extrahepatic bile ducts by working out the methodological aspects of navigation technologies.

Materials And Methods: The analysis of literature data on various approaches to improve the perioperative identification of anatomical structures during laparoscopic cholecystectomy, including the ICG-fluorescent cholangiography, was carried out. This program was implemented during the provision of elective surgical care to 24 patients with cholelithiasis who underwent laparoscopic cholecystectomy with ICG-fluorescent navigation.

[Specific features of normal vaginal microflora in girls of preschool age].

The study of the vaginal microbial cenosis in 20 healthy girls aged 3-7 years did not confirm the notion on the dominating role of cocci (including epidermal staphylococci). The associations of 2-5 different microorganisms represented by more than 20 species in an amount of 4-6 Ig PFC/g of discharge were established. In the overwhelming majority of the examinees (84.
