The article presents the main stages of the development of ideas about a fairly rare pathology in clinical practice the syndrome of compression of the ventral trunk. Until the mid-nineteenth century, reports of the clinical picture of chronic abdominal ischemia were more descriptive. Serial pathoanatomic studies, comparison of anatomical features revealed at autopsy with clinical manifestations accompanying these changes, contributed to the isolation of chronic ischemic disease of the digestive system in a separate nosological form. The discovery of angiography contributed to the significant development of vascular surgery and the isolation of the ventral trunk compression syndrome as an independent disease, since it allowed for a lifetime comparison of the detected changes in blood vessels with the clinical manifestations of the disease. The term ventral trunk compression syndrome was first introduced by P. Harjola when describing a case of abdominal pain in a patient with compression of the ventral trunk by the neuroganglionic tissue of the ventral plexus. Later, J. Dunbar confirmed the Association of clinical manifestations of chronic abdominal pain with compression of the ventral trunk by the median arched ligament of the diaphragm. In English-language literature, the disease was named Dunbar syndrome. The effectiveness of eliminating the symptoms of this disease by surgical dissection of compression structures has been proven. Further study of this problem developed in parallel with the development of surgery in General in accordance with the emergence and introduction of new surgical technologies. The purpose of numerous studies was to study the etiopathogenetic mechanisms of the occurrence of a variety of clinical manifestations of this syndrome and improve the results of its treatment by improving known surgical techniques and introducing new ones.

Currently, bariatric (metabolic) surgery is the main effective treatment of obesity and associated pathological conditions. The features of the course of obesity as a chronic progressive disease, heterogeneous etiology, clinical manifestations and a steady increase in number of patients worldwide make the problem of bariatric interventions extremely urgent. The article presents the analysis of modern data concerning the choice of the method of surgical benefits in patients with obesity and their own clinical experience.

Celiac trunk compression syndrome is a symptom complex arising from compression of the celiac trunk by the median arcuate ligament, crura of diaphragm or ganglion tissue of the celiac plexus. The main clinical manifestations of this pathological condition are abdominal pain syndrome, indigestion and weight loss. The disease is detected in 0.4–1 % of people in the population, more often in young people. The pathophysiological mechanisms of the development of celiac trunk compression syndrome remain not fully understood, but the key reason for its development is ischemia of the digestive system. The main instrumental methods for diagnosing compression of the celiac trunk are ultrasound duplex scanning of the abdominal aorta and visceral arteries and spiral computed angiography. The only effective treatment for celiac trunk compression syndrome is surgery. Currently, both classical techniques and various minimally invasive technologies are used to decompress the celiac trunk. The advantages of open access include good visual and manual control of anatomical structures, the possibility of eliminating complications, changing the tactics of surgical intervention, if necessary, performing vascular reconstruction. The advantage of minimally invasive surgical technologies is minimal trauma to the abdominal wall tissues, minor postoperative pain syndrome, early rehabilitation, a low risk of developing cusp, wound infection and hernial defects. Regardless of the methodology, surgical treatment can achieve a positive effect in 75–90 % of patients with celiac trunk compression syndrome. These are the modern concepts of epidemiology, pathogenesis, clinical manifestations, diagnosis and methods of treatment of this pathological condition.

Introduction. Currently, traditional methods and minimally invasive surgical technologies are used in the treatment of celiac trunk compression syndrome. The choice of treatment method remains a subject of discussion. The drawback of the classical approach – laparotomy – is a significant trauma to the tissues of the abdominal wall, the risk of adhesions, wound infection and hernias. The disadvantage of videosurgical techniques is the risk of developing life-threatening bleeding requiring conversion of access. The main cause of this complication is damage to the wall of the aorta, celiac trunk and its branches during the intervention.Methods and materials. A set of tactical and technical principles was developed to reduce the risk of bleeding during laparoscopic decompression of the celiac trunk. The prerequisites were an assessment of the individual architectonics of the vessels according to 3D reconstruction data, the location of working instruments as parallel to the celiac trunk course, retrograde access to the compression zone, the use of an ultrasonic or bipolar dissector, contact with the vascular wall only with passive branches. With these principles surgical intervention was performed in 12 patients.Results. Complication (bleeding from the branch of the lower phrenic artery) – occurred in one (8.3 %) case – was eliminated laparoscopically. The average duration of the operation was 85 minutes, the average hospital day after the operation was 5 days. Treatment results within 3 to 12 months were evaluated in 8 out of 12 (66.7 %) patients. In 7 (87.5 % of patients with the studied results) cases, complete regression of symptoms and restoration of normal blood flow were noted. One (12.5 %) person had a slight abdominal pain syndrome against the background of normal hemodynamics in the celiac trunk.Conclusion. The presented data are comparable with the results of traditional surgical methods of treatment of celiac trunk compression syndrome and are the basis for further research.

The article discusses modern methods of treatment of morbid obesity and associated diseases. It is known that obesity leads to disability in people, including young people, due to the frequent development of severe comorbid diseases. According to current clinical guidelines, the main goals of treating obese patients are: weight loss, achieving good metabolic control, and improving the course of diseases associated with obesity. A small selection of drugs for the treatment of obesity, the need for strict adherence to indications and contraindications to their appointment, significantly limits the possibilities of drug therapy for morbid obesity. With morbid obesity, the effectiveness of conservative treatment is only 510%. Up to 60% of patients cannot maintain the result of weight loss within 5 years of observation. Long-term use of bariatric surgeries, the purpose of which was initially to reduce body weight in patients with morbid obesity, showed certain possibilities of surgery in compensating for a number of diseases associated with obesity. Therefore, at present, the concept of bariatric surgery is not only to reduce the patients weight, but also to achieve beneficial metabolic effects (normalization of glycemia, lipid metabolism). In this regard, modern bariatric interventions are united by the term metabolic surgery. It has been proven that compensation of non-insulin-dependent diabetes mellitus after bariatric interventions is observed in 4295% of patients, depending on the type of surgery, duration of non-insulin-dependent diabetes mellitus and basal C-peptide level. As a result of many years of research, bariatric surgery has allowed for the first time to formulate the term remission of non-insulin dependent diabetes mellitus.
