The aim: To study the effectiveness of the enhanced recovery after surgery (ERAS) protocol for laparoscopic hernioplasty (LH) in patients with ventral hernias (VH). Materials and methods: 190 patients with VH after laparoscopic prosthetic hernioplasty with intraperitoneal mesh placement (IPOM) were included in the study and divided into two groups. The study group (ERAS group) included 92 (48.4%) patients to whom the ERAS protocol was applied, the control group (preERAS group) – 98 (51.6%) patients. The width of the hernia was more than 10 cm in 25 (13.2%) patients of the ERAS group. For them botulinum toxin type A (BTA) was injected into the muscles of the anterior abdominal wall 4 weeks before the operation. In the postoperative period, the duration of the operation, hospital length of stay, the intensity of the pain syndrome and well-being, the level of C-reactive protein (CRP) and interleukin-6 (IL-6) on the first postoperative day were evaluated. Results: After the introduction of BTA in 25 patients of ERAS group, the hernial defect decreased by an average of 4.6±0.62 mm and in all cases became less than 10 cm (р

A systematic review and meta-analysis of data on the problem of enhanced recovery in urology was performed. Inclusion criteria – clinical trials of the enhanced recovery program in urology.The aim of the study was to assess the significance of the enhanced recovery program (ERP) in the provision of surgical care in the “urology” profile.Materials and methods. The systematic review was performed according to the guidelines for the presentation of systematic reviews and meta-analyses by PRISMA. The registration number in the international system Prospero was received (CRD42022358982). The review included 364 studies. Studies in urologic oncology were excluded from the meta-analysis. The meta-analysis included 15 studies involving 2293 subjects. A comparison was made between the application of ERP and the standard treatment protocol.Results. The use of ERP leads to an expected two-fold reduction in the duration of postoperative length of hospitalization (OR = –1.96; 95% CI: –2.56÷–1.36; p Class 2.

The results of numerous studies prove the high efficiency of regulating the flow of formation water into productive reservoirs by injecting non-hydrocarbon gases near the initial gas contour. In order to improve the existing technologies for the development of fields in a water drive, a study of the effectiveness of cyclic injection of carbon dioxide into a gas condensate reservoir was carried out. The study was conducted for varying carbon dioxide injection cycle times using Schlumberger’s Eclipse and Petrel simulation tools. According to the results of calculations, it was found that an increase in the duration of the injection cycle of carbon dioxide leads to a decrease in the duration of the development period of the reservoir until the moment of breakthrough of carbon dioxide. Rapid breakthrough of non-hydrocarbon gases into production wells results in shutdowns in order to maintain production gas condition to industry standards. This, in turn, leads to a decrease in the technological indicators of the development of a productive reservoir. However, analyzing the research results, it should be noted that the injection of carbon dioxide into the reservoir at the initial gas-water contact leads to a slowdown in the flow of formation water into the gas-saturated horizons. Based on the results of processing the calculated data, the optimal value of the duration of the cycle of injecting carbon dioxide into the reservoir was established, which is 7,89 months. The final gas recovery factor for the optimal value of the injection cycle time is 64,14 %, and in the case of depletion development – 54,31 %. The results of the studies carried out indicate the technological efficiency of injecting carbon dioxide into the productive reservoir on the vboundary of the initial gas-­water contact in order to regulate the process of inflow of edge waters into gas-saturated horizons and increase the final gas recovery factor.

Introduction. The implementation of ERAS (Enhanced recovery after surgery) protocols has been shown to be effective in orthopedics, bariatric and colorectal surgery. However, the safety and feasibility of implementing accelerated rehabilitation protocols in patients underwent distal pancreatic resection is not well studied.The objective was to analyze the results of the application of accelerated rehabilitation protocols in patients underwent distal pancreatic resection.Methods and materials. A retrospective - prospective, single-center study was conducted. The study included 60 patients. Patients were divided into two groups (control group - 30 patients, perioperative management was carried out according to standard methods and the main group - 30 patients, perioperative management was carried out according to the accelerated rehabilitation protocol). All patients included in the study underwent distal pancreas resection.Results. Patients in the analyzed groups were comparable by gender, age, body mass index, and ASA score. The frequency and severity of postoperative complications in the compared groups was comparable. The frequency of early activation of patients was significantly higher in the main group (86.7 vs 56.7; p

Guidelines for enhanced recovery after surgery (ERAS) are widely used and their efficiency was clearly demonstrated by numerous studies. Number of publications on this topic in bariatric surgery is significantly lower compared with other fields of surgery. However, the data accumulated allow to compose recommendations based on studies with high level of evidence. Authors review existing methods of enhanced recovery in their implementation into bariatric surgery. Enhanced recovery methods can be used to optimize all stages of perioperative care and include data on preoperative preparation, maintenance of electrolyte balance, prevention of postoperative nausea and vomiting, sufficient analgesia and safe discharge form hospital. Suggested guidelines for bariatric surgery are implied to be used by a multidisciplinary team.

Objective: To study the outcomes of fast-track recovery in patients with perforated duodenal ulcer (PDU)., Material and Methods: There were 138 patients with PDU who underwent surgical treatment for the period from January 1, 2015 to December 31, 2019. Patients were divided into 3 groups: main group, control group 1 (CG-1) and control group 2 (CG-2). The main group (fast-track group, FT-group) included 51 patients who underwent laparoscopic suturing of PDU followed by enhanced recovery (fast-track). CG-1 comprised 44 patients who underwent open suturing of PDU and conventional perioperative treatment. CG-2 consisted of 43 patients who underwent laparoscopic suturing and conventional perioperative treatment. Complications were assessed using Clavien-Dindo grading system., Results: In the FT group, postoperative complications were observed in 2 patients (3.92%). Anemia of mixed genesis (Clavien-Dindo grade II) was diagnosed in 1 patient and left-sided lower lobe pneumonia in another one (grade II). There were no deaths. Mean length of hospital-stay was 3.86 days. In the 1 st control group, the largest number of complications was observed ( n =12, 27.27%) including 9 extra-abdominal complications (pulmonary disorders (II) - 7 patients (15.9%); sepsis (IVB) - 1 (2.27%), delirium (IVA) - 1 patient (2.27%), postoperative wound seroma (IIIA) - 1 (2.27%) patient). Intra-abdominal complications consisted of compensated pyloroduodenal stenosis (II) in 1 (2.27%) case, recurrent bleeding from acute gastric and duodenal ulcers (IIIB) in 1 (2.27%) patient. Mortality rate was 4.54% ( n =2) in this group (progressive multiple organ failure). Mean length of hospital-stay was 7.56 days. In the 2 nd control group, postoperative complications included extra-abdominal (pulmonary disorders (II) - pneumonia in 4 (9.3%) cases, spontaneous pneumothorax (IIIA) in 1 (2.32%) case) and intra-abdominal events (duodenitis (II) in 1 (2.32%) patient and compensated pyloroduodenal stenosis (II) in another 1 (2.32%) patient). There were no lethal outcomes in this group. Mean length of hospital-stay was 6.7 days., Conclusion: Treatment outcomes in patients with perforated duodenal ulcer confirmed an effectiveness of laparoscopic suturing and complete abdominal sanitation. These measures create the prerequisites for fast track recovery in urgent surgical practice. FT-protocol of inpatient management is followed by reduced hospital-stay and less incidence of postoperative complications. Moreover, this approach promotes early and safe discharge of patients.
