The aim of the study: to improve the results of abdominoplasty in patients with diastasis of the rectus abdominis and umbilical hernia. Materials and methods: the study included 31 patients, 17 of them underwent abdominoplasty with suturing of the rectus abdominis diastasis, 14 women underwent suturing of the rectus abdominis diastasis and hernioplasty. The proposed method was used to form a neo-navel in all patients (RF patent 2749475 of 11.06.21).

Results: In women with di astasis of the rectus abdominis muscles, an umbilical hernia was diagnosed in 45.2 % of cases. 17 patients underwent abdominoplasty with suturing of the diastasis of the rectus abdominis and 14 patients had abdominoplasty, suturing of the diastasis of the rectus abdominis and hernioplasty according to the novel technique. (RF patent 2749475 of 11.06.21). The proposed method of abdominoplasty, which includes suturing of the diastasis of the rectus abdominis and hernioplasty, resulted in a significant improvement in the quality of life of women who underwent the surgery. According to the EuraHSQoL questionnaire, 94 % of respondents reported a statistically significant improvement in physical activity, functional state of the anterior abdominal wall, and aesthetic appearance of the abdomen. Conclusion: a study of the long-term results of using the novel technique showed that no relapses of the diastasis of the rectus abdominis and umbilical hernia were 14 detected during 5 years of observation. When assessing the quality of life according to the EuraHSQol questionnaire, 93.4 % of respondents noted good results in the first year, and 90 % of respondents in the fifth year following the operation.

This paper aims to assess the effectiveness of current approaches to information exchange among key actors in the healthcare system and their impact on healthcare delivery. Specifically, it compares existing approaches to collecting medical data in herniology and explores their potential use in ‘learning healthcare systems'. However, current nosological registries do not fully meet the needs of these systems. One solution is to modify medical information systems to serve as a source of medical data of sufficient quality to supplement existing medical data lakes. Achieving this requires collaboration among clinicians, researchers, medical information system engineers, and data scientists. Establishing legal regulations for the transfer of medical data to scientific and educational organizations is necessary to fully realize the potential of this new type of nosological registry for advancing science and medicine.

The clinical case presented in this article illustrates one of the rare manifestations of systemic sarcoidosis — an isolated sarcoidosis lesion of the spleen. In a 36-year-old patient, based on anamnestic information and preoperative instrumental examination, a nonspecific granulomatous lesion of the spleen was suspected. Surgical intervention was performed in the scope of laparoscopic splenectomy with subsequent morphological verification of the diagnosis. According to the pathohistological examination, the diagnosis of sarcoidosis of the spleen was established. The patient was discharged in a satisfactory condition on the 6^th day.

Aim: assessment of the impact of biological therapy on risk factors for postoperative complications. Materials and methods: the study included 116 patients operated on for Crohn's disease. The mean age of the patients was 38.2 years, among them 65 men (56 %) and 51 women (44 %). The influence of various factors on complications in the postoperative period was analyzed using the IBM-SPSS software for Mac version 22.0 and Microsoft Excel 1997-2003. Results: 32.7 % of the patients received biological therapy, and postoperative complications developed in 31 % of the operated patients. There was no association between receiving biological therapy and the risk of postoperative complications. The risk factor was the formation of a stoma and surgery for emergency indications. Conclusion: an important task before surgical treatment for Crohn's disease is a thorough preoperative preparation and assessment of all risk factors for complications of surgical intervention by a multidisciplinary team.

This work provides a comprehensive overview of the recent advancements in the field of radiomic diagnostics and artificial intelligence (AI) in the diagnosis of pancreatic diseases. The integration of radiochemical analysis and AI has allowed for more accurate and precise diagnoses of pancreatic diseases, including pancreatic cancer. The review highlights the different stages of radiomic analysis, such as data collection, preprocessing, tumour segmentation, data detection and extraction, modeling, statistical processing, and data validation, which are essential for the accurate diagnosis of pancreatic diseases. Furthermore, the review evaluates the possibilities of using AI and artificial neural networks in surgical and oncological pancreatology. The features and advantages of using radiochemical analysis and AI in the diagnosis and prognosis of pancreatic cancer are also described. These advancements have the potential to improve patient outcomes, as early and accurate diagnosis can lead to earlier treatment and better chances of recovery. However, the limitations associated with the use of radiometry and AI in pancreatology are also noted, such as the lack of standardization and the potential for false positives or false negatives. Nevertheless, this work highlights the potential benefits of incorporating radiochemical analysis and AI in the diagnosis and treatment of pancreatic diseases, which can ultimately lead to better patient care and outcomes.

The study on gastrointestinal tract reconstruction after proximal gastrectomy (PG) for stomach cancer aimed to identify the most optimal way to restore the integrity of the gastrointestinal tract. The study involved a comparative analysis of 23 papers with a total of 1,517 cases of reconstructions after PG from four countries during the period 2010—2021. The five most commonly described types of reconstruction after PG were analyzed: jejunal interposition, esophagogastric anastomosis, ‘double tract' reconstruction, ‘double flap' reconstruction, and jejunal pouch interposition. The comparison criteria included the duration of surgeries, intraoperative blood loss, length of hospital stay, as well as postoperative complications such as anastomotic leakage, anastomotic stricture, reflux esophagitis, and residual food. The results of the study can provide valuable insights for surgeons in choosing the most optimal type of reconstruction after PG, thus reducing the risk of postoperative complications and improving the quality of life of patients with stomach cancer.

Degenerative diseases that involve excessive formation of fibrous tissue are complex and common problems. These diseases cause pronounced and often irreversible changes, resulting in the dysfunction of the affected organ. Osteoarthritis, osteoarthritis, and arthrofibrosis are pathological conditions characterized by chronic inflammation and excessive proliferation of connective tissue. The elbow joint, being the most mobile and anatomically stable joint in humans, is often affected by arthrofibrosis, resulting in significant functional impairment and reduced quality of life for patients. This problem has significant social relevance. Understanding the mechanisms that lead to arthrofibrosis can help determine the most effective therapeutic interventions, the optimal timing for treatment and rehabilitation, and the use of preventive measures to reduce the risk of relapse.
