In recent years, several consensus and guidelines for the diagnosis and treatment of chronic pancreatitis have been published. In 2017, the Russian and Pan-European (HaPanEU) consensus was published, in 2018 — the international consensus on minimal change pancreatitis, in 2020 — the clinical guidelines of the American College of Gastroenterology, in 2021 — the British clinical guidelines. Many of their provisions overlap. This review article analyzed the main provisions of the latest recommendations, taking into account the possibility of their adaptation to Russian clinical practice.

Aim: To identify a connection between acute and chronic pancreatitis and primary hyperparathyroidism on the base of clinical cases. To consider the features of the diagnosis and treatment of acute and chronic pancreatitis with primary hyperparathyroidism.

Materials and methods: Over the past 10 years, there have been observed 3 cases of pancreatitis with primary hyperparathyroidism. Two patients were diagnosed with chronic pancreatitis, one patient was diagnosed with acute destructive pancreatitis. Patients were undergoing surgery, parathyroidectomy was performed.

Results: Primary hyperparathyroidism is rarely associated with the occurrence of acute or chronic pancreatitis, but hypercalcemia plays an important role in the pathogenesis of these diseases. Pancreatitis usually occurs in the late stage of hyperparathyroidism, which explains the low prevalence of this association in developed countries, where primary hyperparathyroidism is diagnosed at an early stage of the disease.

Conclusion: These clinical cases of radical surgical treatment of parathyroid adenoma associated with severe concomitant pathology testifies to the effectiveness of the surgical method in some cases. It is necessary to take into account severe concomitant pathology and diagnose and correct it in time.

Aim: to study the quality of life and the emotional state of patients with chronic pancreatitis on the background of postoperative hypothyroidism and the possibility of effective rehabilitation.

Materials and methods. 270 patients with chronic pancreatitis were examined, among which 40 patients with primary postoperative hypothyroidism, who made up group 1, group 2 included 30 patients without thyroid pathology. Patients underwent a blood test according to the main biochemical parameters, hormonal blood count, ultrasound of the thyroid gland, hepatobiliary and duodenal zone. The study of quality of life and psychoemotional state by tests.

Results In patients with chronic pacreatitis in combination with postoperative hypothyroidism among diseases of the hepatoduodenal zone, chronic non-calculous cholecystitis and non-alcoholic fatty liver disease were identified that are clinically characterized by abdominal pain syndrome according to the GSRS questionnaire. Patients revealed mild depressive state, high levels of personal and situational anxiety. The quality of life of patients was reduced both in physical and in psychological components, due to indicators of role-playing physical and emotional functioning. Against the background of treatment with a combination of succinate-containing drugs, the severity of depression, situational and personal anxiety decreased, and role functioning due to physical and emotional state, social functioning increased.

Conclusions: The use of combination therapy with sodium levothyroxine and ethylmethylhydroxypyridine succinate in patients with comorbid pathology during postoperative hypothyroidism improves the clinical picture, psychoemotional balance and quality of life.

Chronic pancreatitis is one of the most pressing problems of pediatric gastroenterology and surgery of hepatopancreatobiliary organs. Diagnosis and treatment of this category of patients requires a comprehensive examination using modern highly sensitive research methods and the collegial participation of a surgeon, gastroenterologist and endocrinologist. Due to the fact that the algorithm for managing these patients is not regulated, patients often receive enzyme replacement therapy for a long time, with indications for surgical treatment. In addition, the non-specificity of complaints and clinical manifestations of chronic pancreatitis, the asymptomatic course and the initial detection of exo- and endocrine insufficiency lead to a later choice of the optimal treatment method and increase the risk of complications. The key to effective care for children with chronic pancreatitis is the staging and continuity in research and treatment. At the Center for the Treatment of Developmental Anomalies and Diseases of the Hepatopancreatobiliary System in Children on the basis of the Filatov Hospital, highly effective interventions are carried out for chronic pancreatitis in children, the purpose of which is to ensure an adequate outflow of pancreatic juice using longitudinal pancreaticojejunostomy, which, in addition to draining the pancreas, allows to achieve clinical remission and stop the progression pathological process, including diabetes mellitus. The article reflects the experience of diagnosis and treatment of chronic pancreatitis in children.

Introduction. Inflammatory bowel diseases are a group of chronic, immune-mediated diseases of unknown etiology. Etiotropic therapy of IBD does not exist, all drugs used to treat IBD have a pathogenetic effect. In the treatment of IBD biologic therapy is used. The most previously registered group of biologics are anti-TNF-α. But, after the expiration of the relevant patents, biosimilars appeared on the market (analogs, comparable in quality to the already approved reference product).

Materials and methods. A retrospective study was conducted on the basis of the Ryzhikh Natianal Medical Research Centre for Coloproctology of the Ministry of Health of the Russia, which included 46 patients who switched from therapy with the original infliximab or adalimumab to biosimilar therapy.

Discussion. This study showed that when switching therapy with the original drugs infliximab and adalimumab to biosimilars, the effectiveness of therapy does not significantly decrease with the use of biosimilars Infliximab BIOCAD and Dalibra. However, a statistically significant decrease in efficacy was revealed when switching from therapy with the original Infliximab to Flammegis. Considering that the use of biosimilars can reduce the cost of treatment and reduce the burden on the health budget, it is necessary to continue this study in order to obtain longer-term results.

In patients with acute pancreatitis (AP), diagnostic imaging is very important for determining disease etiology and its primary diagnosis in unclear clinical situations. This review presents literature data about the methodology, indications and timing of various imaging methods in the diagnosis and treatment of AP. The detailed information about modern tomography capabilities in stratification of AP severity and morphological assessment of its local complications is presented. Currently, beam imaging methods are crucial in planning of draining minimally invasive surgical interventions for AP and subsequent assessment of their effectiveness, which makes the radiologist a permanent and key member of a multidisciplinary team of specialists, contributing to the optimization of the immediate and long-term results of treatment of this complex pathology.

The frequency of intestinal microbiota disorders in patients with chronic pancreatitis (CP) is extremely high and can reach 97%. The bacterial overgrowth syndrome (SIBO) and the syndrome of increased epithelial permeability (SPEP), developing against the background of excretory insufficiency of the pancreas, affect the severity of the clinical picture of the disease, reduce the effectiveness of enzyme replacement therapy and generally contribute to the further progression of CP.

The article presents a modern view on the mechanisms of the formation of SIBO and SPEP in CP. There is their aggravating effect on the course of the disease and the aggravation of disorders of the digestive and absorption processes that accompany them is shown and analyzed in the article.

For decontamination of conditionally pathogenic and pathogenic flora, increasing the number and metabolic activity of indigenous microflora in patients with CP, the use of a non-absorbable broad-spectrum antibiotic rifaximin is effective. In order to restore the barrier function of the gastrointestinal mucosa, the drug of choice is rebamipid, a universal cytoprotector that affects all three levels of epithelial tissue protection (preepithelial, epithelial and subepithelial).

Conclusion. CP is characterized by the complexity of its etiology and pathogenesis. Bacterial factors, in particular, SIBO and SPEP, play an essential role in the development of inflammatory changes in the pancreas. In the complex therapy of CP, it is advisable to take measures aimed at correcting disorders of the intestinal microbiota.

Changes in the exocrine function of the pancreas often develops after proximal and distal resections. Exocrine pancreatic insufficiency (EPI) is characterized by a reduced secretion of pancreatic enzymes, because of which the digestion and absorption of nutrients is impaired. Clinical manifestations of EPI and, as a consequence, changes in nutritional status significantly affect the quality of life of patients.

Despite of achieved progress in advanced pancreatic cancer treatment, the disease outcomes remain far from satisfying. The peculiarity of malnutrition treatment in these patients is the result of its causes complexity and progressively growing manifestations extent. The review represents mechanisms of malnutrition and approaches to their treatment.

The regulation of the digestive glands of the stomach and pancreas in the body of animals and humans is provided by peptides, most of which are in various molecular forms. 10 molecular forms of peptides of the gastrin group and 5 peptides of the cholecystokinin (CCK) group have been identified, containing in their structure from 4 to 56 amino acids, the physiological role of which has been little studied. It has been proven that the liver removes up to 85% of short-chain peptides of the gastrin (pentagastrin) and cholecystokinin (CCK-8) groups.

The Aim. Study of a clinical case of metachronous primary multiple cancer of the head of the pancreas and liver.

Materials and methods. The work was carried out with modern domestic and foreign literature sources devoted to the problem of primary multiple malignant neoplasms. A retrospective analysis of the patient’s clinical and anamnestic data was performed, the necessary medical documentation was studied.

Results. In 2011, a pancreatoduodenal resection was performed on a patient for ductal adenocarcinoma of the head of the pancreas. In 2021, an MRI scan revealed a formation in S5-S6 with dimensions up to 34x35x29 mm. According to the histological examination of the biopsy material, hepatocellular carcinoma was confirmed. Resection of the 5th segment of the liver was performed in the conditions of the NMIC Oncology in Rostov-on-Don.

Conclusion. The presented case of primary multiple cancer of the head of the pancreas and hepatocellular carcinoma of the liver is of direct interest both from the point of view of oncological surgery and chemotherapy.

The aim of the study was to evaluate the informative value of various diagnostic methods for spontaneous drainage of the pancreatic pseudocyst into the stomach.

Materials and methods: based on the clinical observation of a patient who received complaints of pain in the epigastrium, an episode of melena, after suffering acute pancreatitis several years ago with the development of pancreatic necrosis with an outcome in the cyst of the tail of the pancreas, drainage of the omentum bag. The patient underwent a comprehensive laboratory and instrumental examination.

Results: ultrasound, endoscopic examination, MSCT suspected a malignant process in the stomach with ulceration and germination into the pancreas. After performing endoscopic ultrasonography, it was possible to differentiate the layers of the formation and make the correct diagnosis, which was confirmed by subsequent MSCT with oral contrast.

Conclusions: a spontaneously opened pancreatic pseudocyst in the lumen of the stomach is a rare and difficult to diagnose disease. An integrated approach, including endoscopic, ultrasound, X-ray, and laboratory methods of investigation when compared with the clinical picture, allows us to verify the formation of the pancreas.

Objective: To present a clinical description of the observation of a patient with Crohn’s disease (CD) with extraintestinal manifestations in the form of granulomatous alveolitis.

Materials and Methods: A brief review of the literature on the current understanding of the prevalence and clinical manifestations of lung lesions in inflammatory bowel diseases (IBD) and CD, as well as a description of a patient with this pathology with the results of autopsy is presented.

Results: The rare presence of granulomatous lung lesions in a patient with CD was proved.

Conclusion: Difficulties in the differential diagnosis and treatment of CD lung lesions are shown. In particular, suspicion of tuberculous lesion, lung abscess creates potential risks of generalization of the process when using such therapeutic effects as glucocorticosteroids, cytostatics, immunosuppressants, biological genetically engineered drugs and active surgical intervention. The authors hope that the described observation will alert doctors in terms of possible systemic pulmonary lesions in CD.

Mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN) is defined as a tumor composed of cells originating from neuroendocrine cells in the embryonic intestine and elements of epithelial adenocarcinoma. To determine the differentiation grade of MiNEN, the proliferation index was used, for which at least 500 cells were examined. MiNEN is a rare neoplasm that is most frequently found in the lower gastrointestinal tract. We present a rare clinical case of surgical treatment of MiNEN of the ascending colon.

Autoimmune Insulin syndrome (AIS), also named Hirata disease, is a rare condition characterized by hypoglycemic episodes due to the presence of high titers of insulin autoantibodies (IAA). AIS is a form of immune-mediated hypoglycemia, which develops when a triggering factor (medication or a viral infection) acts on an underlying predisposing genetic background. The diagnosis of IAS is challenging, requiring a careful workup aimed at excluding other causes of hyperinsulinemic hypoglucemia. The article presents a case of Hirata disease diagnosing of a patient of the therapy department of the Multidisciplinary Medical Center of the Bank of Russia.

Purpose: Determining of the features of the diagnosis of Autoimmune Insulin syndrome (Hirata disease)

Materials and methods: the article presents a clinical case of the diagnosis of Autoimmune insulin syndrome (Hirata disease), focuses on the diagnostic significance of laboratory tests. The article is intended for general practitioners, endocrinologists, gastroenterologists.
