The work is based on the analysis of literature data devoted to the problem of assessing postoperative complications in patients with primary and incisional hernias of the anterior abdominal wall. The main purpose of this review is identifying existing methods for assessing local, general perioperative complications and determining of the most reliable prognostic scales and methods for assessing risk factors among the existing ones.

The first part of the article is devoted to the assessment of the general condition of patients with hernias of the anterior abdominal wall. The existing scales for assessing modifiable risk factors (MFR), methods of preventing complications, including abdominal bandage, are considered. The main risk factors were determined: CDC wound class, patient age, hernia size, smoking, diabetes, risk 3 and higher according to ASA.

In the second part, the assessment of risk factors for complications from the surgical site is considered. The problem of terminology standardization, the difference between surgical site infection (SSI), adverse surgical events (SSO) and surgical site occurrences requiring procedural interventions (SSOPI) is described. Scales for assessing the risks of perioperative complications are presented. The evolution of SSO assessment methods from a four level to a three level scale is described. The Russian experience in assessing the combination of MFR is presented.

The third part describes the importance of evaluating post traumatic stress disorder in patients as a risk factor for an unfavorable course of the postoperative period. The European EuraHS QoL Questionnaire, recommended for use in the European Hernia Registry, is presented. The section also highlights the relevance of the selection of patients with hernias in outpatient surgery and one day hospitals.

The main idea of developing modern methods for assessing complications after hernioplasty is a comprehensive assessment of the patient's individual profile before operations for primary and incisional hernias in different risk groups. Priority should be given to tailored specific electronic questionnaires.

Aim: to investigate the time period and reasons for seeing a doctor of patients with acute thrombosis and to assess treatment satisfaction.

Methods: The main complaints, symptom duration, pain severity and pathological process characteristics of patients with acute perianal venous thrombosis were recorded. The treatment strategy was determined by the doctor and the patient: the surgical thrombosed hemorrhoid removal or conservative treatment with analgesics, venotonics, drugs for stool softening. Pain severity on days 3, 7, 30 and overall satisfactions on day 30 were evaluated.

Results: 62 patients were included. The main symptoms were pain (69.4%) and discomfort (16.1%). During the first 72 hours from the disease onset 21.5% of patients saw a doctor and 66.7% of all patients underwent the surgery, on day 4–7 — 50% saw a doctor and 77% underwent the surgery, > 8 days — 28.5% and 33% respectively. During the appointment pain was 4 points according to VAS, 3 days after surgery — 5.9 points, 4–7 days — 3.9 points, > 8 days — 2.5 points. 64% of patients underwent the surgery with average pain level of 5 points, in the conservative group — of 4.5 points (p = 0.014). On day 30 80.6% of all patients were completely satisfied. Having the pain severity > 4points nobody was satisfied with conservative treatment, while 80% of surgical patients were satisfied.

Conclusion: Considering the symptom duration, pain continuing > 3 days, perianal discomfort ora «bump» the treatment tactics should be accepted by the doctor and the patient together for achieving a high treatment satisfaction.

The work carried out by analyzes of the literature data on assessing the severity of acute pancreatitis and predicting its course and mortality. A comparison of traditional point scales for assessing the severity of AP was made.
As a result of a comparative analysis, it was found that the most objective instrumental method for diagnosing acute pancreatitis and its complications was MSCT with the determination of the CT index of severity. Balthazar scale allows assessing the severity of the disease and forming a prognosis for the development of complications. However, computed or magnetic resonance imaging with intravenous contrast enhancement allows an accurate assessment of the severity of the disease not earlier than 72 hours and has some contraindications.
Estimating and predictive systems Ranson, APACHE, Krasnorogov, Bozhenkov systems, Pugaeva and Achkasova, BISAP and HAPS allow identyfying the severity of the clinical course of acute pancreatitis, have a high sensitivity, but at the same time require significant time and resources for execution. Glasgow-Imrie, SAPS, MODS, and SOFA scales mainly calculate mortality and degree of multiple organ failure in critically ill patients; these severity assessment systems are not specific for patients with acute pancreatitis.
The optimal scale for assessing the severity of AP should allow assessing the patient's condition and prognosis from the moment of admission to the outcome of the disease. The practicing surgeon will be interested in an affordable, inexpensive, easy-to-use system for determining the severity of acute pancreatitis. For surgeons, the time factor plays a key role in determining tactics, and, therefore, improves the prognosis of the disease.

This article gives an overview of mechanical esophageal anastomosis. The results of the esophageal anastomoses formation by using circular and linear stitching devices (staplers) by Russian and foreign authors are presented in chronological order. The faults of staplers, complications associated with them are described. The importance of the problem related to the choice of anastomotic technique to reduce the risks of specific complications such as leakage and stricture of esophageal anastomosis was remarked by authors. The advantages and disadvantages of the currently known esophageal anastomotic methods have been analyzed. It was noted that mechanical side-to-side anastomoses are associated with low frequency of leakage, stricture, postoperative mortality, that’s why they have become preferable, especially in the mini-invasive reconstructive surgery. The authors concluded that the question about the feasibility of mechanical esophageal anastomoses formation is not answered, the evaluation of the properties of modern staplers and the search for the best esophageal anastomotic method are relevant for modern surgery.

Еsophageal achalasia is a neuromuscular disease of esophagus characterized by a distortion of the relaxation of the lower esophageal sphincter (LES) and manifested by marked clinical symptoms. To date, methods for diagnosing pathology and various surgical methods for its correction have been developed and actively used. In this review, the authors summarized all available data on principles of modern classification based on the identification of characteristic diagnostic criteria of the disease. The modern treatment methods are described in detail, the effectiveness of the presented methods is evaluated.

Acute thrombosis of the external hemorrhoid node is one of the common manifestations of hemorrhoids and a frequent reason for seeking specialized medical care. Despite existing prospective studies proving the effectiveness of operative treatment, there is no clear position in determining the indications, timing and methods of surgery, nor the combination of the latter with conservative therapy.
The article formulated and described the original clinical-morphological classification of acute thrombosis of the external hemorrhoid node based on the data of its ultrasound examination (ultrasound). Effectiveness of various methods of treating acute thrombobosis of external hemorrhoid node, carried out on the basis of proposed classification, is evaluated.
Purpose of the study. Improving treatment outcomes for patients with acute thrombosis of the external hemorrhoid node.
Results. Ultrasound types of thrombosis of external hemorrhoidal node are revealed:

– mononuclear (in ultrasound, it is a single thrombus or a dense, intimately soldered group of thrombotic masses of an an- or isoechogenic structure with untested swelling of the skin and subcutaneous fat (PWD), from 10 mm or more in size);

– polynuclear (clusters of thrombotic masses of an- or isoechogenic structure up to 10 mm in size, located at a short distance from each other, with moderate swelling of the skin and subcutaneous fat);

– edema (during sonography, multiple small, up to 2–3 mm, anechogenic thrombotic masses are visualized against the background of pronounced edema of subcutaneous fat fiber and skin).

Effectiveness of various methods of treating patients with acute thrombosis of external hemorrhoid node in groups formed on the basis of proposed classification is evaluated. It has been found that in patients with edematous sonographic type of thrombosis, it is more advisable to apply only conservative therapy or carry out surgical treatment after completion of taking diosmin-containing preparations. Such tactics reduced the duration of treatment and reduced pain syndrome. In patients with a mononuclear type of thrombosis of the external hemorrhoidal node, a similar result was noted during surgery and the beginning of conservative therapy on the day of circulation.
Conclusion. Application of ultrasound diagnostics allows establishing the type of hemorrhoid node thrombosis and using the obtained data when choosing treatment tactics. A differentiated approach to treating this category of patients, based on the proposed classification, allows improving the treatment results of patients with acute thrombosis of the external hemorrhoid node.

Background: A high worldwide incidence of colorectal cancer defines the importance of search not only for effective treatment methods, but also for risk factors for the cancer development and its worst prognosis. The influence of many genetic factors, environmental characteristics and lifestyle features has already been proven, and recently the attention of researchers is being focused on the study of microbiota and, in particular, various parasitic intestinal diseases in the context of risk factors for colorectal cancer.
Clinical case presentation: we demonstrate an incidental finding of parasitic invasion signs during the pathomorphological examination of the surgical specimen in a patient without an epidemiological history.
Conclusion: Further studies are needed not only to confirm and substantiate the role of micro- and macroorganisms inhabiting the intestine in the development of oncological diseases, but also to identify individual links of pathogenesis, pathological pathways and signaling molecules involved in carcinogenesis. Research like this could help broaden knowledge about both the risk factors and predictors of colorectal cancer and the potential sites for targeted therapy.

Background: Recurrent postoperative perineal hernia is a rare complication of such operation as posterior pelvic evisceration. This condition can reduce the quality of life in the postoperative period and requires surgical restoration of the impaired pelvic anatomy.
Clinical case: A 54-year old female patient applied to the MSU University clinic in July 2020 with the protrusion in the perineal area. She was diagnosed with recurrent perineal postoperative hernia. She was diagnosed with rectal cancer T4N1M0 and uterine dysplasia in 2017, 6 courses of neoadjuvant polychemoradiation therapy were performed; she underwent extralevator abdominal-perineal resection with uterine extirpation and the permanent colostomy formation in 2018. A perineal postoperative hernia was diagnosed in March 2020, perineal transabdominal plastic surgery was performed with a mesh implant. A recurrent perineal hernia was diagnosed in April 2020, the patient underwent laparoscopic alloplasty with a composite mesh implant. On the 9th postoperative day, she was discharged in a satisfactory condition without any complaints.
Conclusion: Postoperative perineal hernia is a fairly rare complication in surgical practice. The recurrent rate is quite high. The insufficient number of patients, the short follow-up period and the wide range of surgical treatment methods do not allow evaluating the results adequately. It is necessary to conduct large randomized clinical trials to assess the efficacy of surgical interventions and to determine the indications for certain procedures.

The article is devoted to the current trend of modern orthopedics – the surgical treatment of local full-thickness defects in the hyaline cartilage of the knee joint. This pathology is diagnosed in 5-10% of patients with diseases and injuries of the knee joint.
Materials and methods: The authors of the article presented one of the most modern and available technologies for the restoration of cartilage defects – the technology of matrix-induced autochondrogenesis (AMIC – autologous matrix-induced chondrogenesis). This operation technique was used in 63 patients. The article presents the indications and technique of surgery, considers possible errors, complications, criteria for evaluating treatment outcomes.
Results: treatment outcomes in terms of up to 13 years were studied in 56 patients. Good treatment results were observed in 53 patients. In all cases, high-quality and regeneration of the cartilaginous surface of the femoral condyles was achieved.
Conclusion: Analysis of the outcomes of treatment of patients after implantation of collagen membranes in various modifications allows the authors of the article to recommend this technique for widespread use in clinical practice.
