The article focuses on the professional and scientific path of Professor Ivan Mykolayovych Ishchenko. He was a leading Ukrainian surgeon, a renowned scientist, an accomplished teacher, and a great humanist who formed the ideology of surgical science. Professor Ishchenko defined and developed promising directions for scientific research in the fields of military field surgery, urology, traumatology, neuro‑ and thoracic surgery, and tissue transplantation. His scientific interests included the surgical treatment of diseases of the biliary tract, liver, and stomach as well as theoretical and practical issues of anesthesia administration.

The modern stage of development of surgery, especially minimal invasive technologies, has significantly changed the surgeons' thoughts about the perioperative period. Until the end of the twentieth century, pre‑ and postoperative fasting was the most important requirement in planned surgery. It was believed that it could help to avoid complications both during surgery and in the early postoperative period. H. Kehlet in his fundamental work outlined the factors that allowed to accelerate the patient's recovery after surgery, namely: the absence of preoperative fasting. Objective — to evaluate the effectiveness of nutritional support for surgical patients within ERAS (Enhanced Recovery After Surgery) and ESPEN (European Society for Clinical Nutrition and Metabolism) protocols. Materials and methods. This research included both traditional laparoscopic cholecystectomy (177 cases) and single‑port transumbilical cholecystectomy (8); among laparoscopic bariatric interventions, the major part was represented by classical Roux‑Y gastric shunting (28), as well as sleeve gastrectomy (5) and mini‑gastric shunting (4); among 123 different laparoscopic hernioplasties, in 64 cases transabdominal preperitoneal (TAPP) was performed for bubonocele, intraperitoneal onlay mesh (IPOM) for postoperative ventral and umbilical hernias (59), laparoscopic crurography and fundoplication with and without alloplasty (33). For each type of surgery two groups we identified: control and experimental. Both groups were followed by ERAS protocols in addition to nutritional support. With the prior consent of patients before surgery: the experimental group received full perioperative nutritional support according to our local protocols using protein‑enriched sip feeding formula Nutridrink Protein, the control group followed the traditional scheme of fasting during 12 hours before surgery and received regular drinking water instead of protein mixtures at the first postoperative day. Results. We found statistically significant difference between control and experimental groups in assessing of two important parameters as hunger and weakness. The hunger after laparoscopic cholecystectomy was 1.5 times (p

The article highlights the professional and scientific path of Professor Oleksiy Petrovych Krymov — professor of surgery and head of the Department of Faculty Surgery of the Kyiv Medical Institute.

The article presents the professional and scientific path of Professor Volodymyr Opanasovych Karavaiev — the first professor of surgery, first head of the department, first organizer and first dean of the medical faculty of St. Volodymyr University, who worked at the university clinic (now Kyiv City Clinical Hospital No18).

Obesity causes increased morbidity, disability and mortality rates as well as affects the quality of life. Given the known risks to the patient’s health, the International Federation for the Surgery of Obesity and Metabolic Disorders pays special attention to the problem of morbid obesity (body mass index ≥ 40 kg/m2), with particular emphasis on super‑obesity (body mass index ≥ 50 kg/m2). Objective is to investigate the role of endoluminal interventions in the preparation of super obese patients with high risk of surgical and anaesthesia‑related complications for bariatric surgery. Materials and methods. From 2011 to 2018, 97 patients with morbid obesity and high risk of surgery and anaesthesia‑related complications (ASA PS III — IV) underwent a course of treatment at the clinical setting of the Department of General Surgery No2 of Bohomolets National Medical University. The treatment was carried out in 2 stages. In the main group (n = 60), the first stage of treatment included the intragastric balloon placement for a term of 6 months. The control group (n = 37) received a six‑month conservative therapy. In the second stage of treatment the patients of both groups underwent a surgical procedure for the morbid obesity management. Results. The outcomes of the first stage of treatment showed that the patients, who underwent the intragastric balloon placement, had statistically significantly (p 0.05). Conclusions. The results of the study provide strong evidence that the intragastric balloon placement for a term of 6 months reduces surgical and anaesthetic risks, contributes to the improved function of the cardiovascular and respiratory systems as well as gives a boost to carbohydrate metabolism, and, therefore, can be suggested for the preparation of super obese patients with high risk of surgical and anaesthesia‑related complications for bariatric surgery.
