Duplication of the gastrointestinal tract is a relatively rare malformation. The incidence is approximately 1 in 10 000 live births with the small intestinal duplication in most cases. Malformations with a long duplication part are considered technically complex. A successfully treated clinical case of the subtotal small intestinal duplication in a child is presented in the article. The mid-median mini-laparotomy was performed and a subtotal 1 meter length small intestinal duplication was revealed (from the Treitzs ligament to the ileum in 50 cm from the ileocolic valve). The proximal part of the intestinal duplication and its mucous membrane of the distal part with the common wall were completely removed. Histological examination found ectopia of the gastric mucosa and pancreatic tissue. Surgical treatment of this malformation is aimed at the complete removal of the duplication part due to possible ectopia of the gastric mucosa or pancreatic tissue. If the resection of an entire part of the intestinal duplication is technically impossible, the mucous membrane can be removed.

It was found that dogs with a subcutaneous transplant secreting and discharging pancreatic juice externally absorbed no more fat than dogs in which the pancreatic remnant was undergoing rapid atrophy and sclerosis. Hence, the condition of the pancreatic tissue remaining in the body does not influence the amount of fat absorbed by the intestine. The absorption of fat by the intestinal mucous membrane is always markedly disturbed when the pancreatic secretion is excluded from the intestine. After the complete removal of all pancreatic tissue from an animal, the absorption of considerable amounts of fat can still take place.

SummaryTwo groups of six sheep were fed either dried-grass or ground maize-based diets for at least 4 weeks before slaughter. Samples of the small intestinal mucosa and spancreatic tissue were assayed for a-amylase, glucoamylase, maltase and oligo-l,6-glucosidase.The pancreatic tissue contained high activities of α-amylase and much lower activities of glucoamylase, maltase and oligo-1,6-glucosidase. There was no effect of diet on the specific activities of any of these enzymes in the pancreatic tissue.The activity of α-amylase adsorbed on to the mucosa of the small intestine was greatest in the proximal region of the small intestine, the activity generally declining with increasing distance away from the pylorus. There was no diet effect on the absorbed α-amylase activity.Similar patterns of distribution along the small intestine were observed for maltase, glucoamylase and oligo-1,6-glucosidase with the highest activities in t he jejunum. There was no overall effect of diet on glucoamylase or maltase specific activities and glucoamylase total activity, although the total activities of maltase and oligo-1,6-glucosidase were significantly greater for the sheep fed the ground maize-based diet (P < 0·05).It is suggested that ruminant animals may be capable of digesting large amounts of starch in the small intestine through an adaptation in the activity of the host carbohydrases.

The article presents some information about xanthomatosis, as well as about xanthomas of the stomach, which are benign formations, but their etiopathogenesis is unknown. Some believe that there is a relationship between xanthomas of the stomach and hyperlipidymia, diabetes, preneoplastic changes in the mucous membrane, age-related features of the gastric mucosa.The clinical case described in this report confi rms the existing point of view about xanthomas as markers of preneopastic changes in the gastric mucosa and its precancerous diseases.

The aim: The aim of the study is a statistical analysis of the mucosa of the stomach affected by Helicobacter pylori in young people studying at the university. Materials and methods: The work contains the results of the study of chronic gastritis of type B in university volunteer students. The study was attended by students of 1-4 courses, aged 17 to 25 years, a total of 50 people. Among them were 28 men and 22 women. Results: Various forms of chronic gastritis were found in the mucosa of the topographic-anatomical sections of the stomach, 90% of which were associated with Helicobacter pylori (HP). In all departments there is a different amount of common forms of chronic gastritis. In the pyloric section only atrophic gastritis was detected – 31.0 ± 8.5. Atrophic gastritis was also dominant on the lesser curvature – 32.3 ± 7.8, but its forms were significantly (p <0.5) less pronounced than in the pyloric section. In the area of the body, the above variants of chronic gastritis were found in 34.3 ± 8.7 cases, and the majority were flat erosive gastritis 51.0 ± 9.3. There is a tendency to reduce the degree of bacterial contamination of the gastric mucosa from its pyloric section and the lesser curvature to the walls of the body. With a decrease in the degree of bacterial contamination of the gastric mucosa, the degree of leukocyte infiltration also decreases. Between the degree of contamination of the mucous membrane of Helicobacter pylori and the degree of leukocyte infiltration of the mucous membrane, the Pearson correlation coefficient is rxy – 0,935, the correlation is very strong, the coefficient of determination is D=rxy^2 – 0,874, the statistically significant dependence on the probability is 0.99. Conclusions: Atrophic or hyperplastic gastritis associated with HP is found in the gastric mucosa, respectively, 90% of cases. The degree of bacterial contamination correlates with the degree of leukocyte infiltration of the gastric mucosa. Atrophic or hyperplastic gastritis Helicobacter pylori-associated is a common disease of people in young and working age.

Superior mesenteric artery aneurysm (SMAA) is reported to be the third-most common type of visceral aneurysm (VA), accounting for 5% of all VAs. The etiology of SMAA is commonly thought to be infection, and it usually exists in the proximal part of the superior mesenteric artery, which is suitable for endovascular treatment. We herein report an extremely rare case of the distal part of SMAA caused by Takayasu's arteritis (TA), which was successfully resected using a mini-laparotomy method without impairing the intestinal blood supply. A 51-year-old woman was admitted to our hospital with sustained fever and lower back pain. Physical examination showed that she had a discrepancies in blood pressure between both arms. Contrast-enhanced whole-body computed tomography showed stenosis of the thoracic aorta and an aneurysm located in the distal part of the superior mesenteric artery. The diameter of the aneurysm was 4.5 cm. The aneurysm was resected via 4-cm mini-laparotomy, and the vascularity of the intestine was successfully preserved. The postoperative course was uneventful, and the patient was diagnosed as having TA based on both clinical and pathologic findings. Additional corticosteroid therapy was started to treat the arteritis, and at 3-month follow-up she was without critical incidents. Mini-laparotomy is a safe and less-invasive approach to treat SMAA, especially when the lesion is located in the distal part of the artery.

Enteric duplication is rare in dogs. Here, we report the rarest form of duplication in which two segments are parallel and share a wall for most of their lengths. A nine-year-old spayed female Yorkshire terrier was referred to the Veterinary Medical Teaching Hospital at Gyeongsang National University due to anorexia and diarrhoea. Physical examination, haematological examination, radiography, and ultrasonography were performed. On physical examination, dry, pale mucous membrane was identified. Moderate anaemia with decreased packed cell volume was detected in complete blood count. Serum urea nitrogen and creatinine levels were mildly increased. Radiographic images revealed no significant findings. On ultrasonographic examination, a multi-layered appearance of a focal small intestinal segment was identified in the left mid abdomen. Following the lesion, it was divided into two small intestinal segments. Based on imaging findings, intussusceptions or enteric duplication were suspected. To resect the abnormal small intestinal segment, enterectomy was performed. Follow-up was not performed because the patient expired during the postoperative recovery time. The histopathological diagnosis was non-communicating small intestinal duplication. Non-communicating intestinal duplication is related to embryologic abnormalities and is usually concurrent with other anomalies such as vertebral malformations and urogenital duplications. However, this case had no other anomalies associated with the malformation of the intestine.

Introduction. Despite a significant number of publications and a concept known as Correa’s cascade, dysplas-tic processes and the mechanisms of gastric carcinogenesis, are still far from being completely understood. Dysplasia and the processes in the mucous membrane adjacent to the tumor node, their significance, and their role in the field cancerization have also been studied insufficiently. The aim of this work was to analyze the frequency of occurrence and some characteristics of high- and low-grade dysplasia in the gastric mucosa at variable distances from the tumor node. Materials and methods. We carried out a prospective histological study of surgical specimens from 49 patients with intestinal type gastric adenocarcinoma. We studied tissues from the tumor node and adjacent gastric mucosa at various distances from the tumor and assessed the frequency of occurrence and some characteristics of low- and high-grade dysplasia. Results. In the mucous membrane adjacent to the intestinal type adenocarcinoma, 73.5% of cases demon-strated low- and high-grade dysplasia. In all cases, background and precancerous processes were found in areas adjacent to the tumor node with low- and high-grade dysplasia. Conclusion. The incidence of low- and high-grade dysplasia detected in the mucous membrane adjacent to intestinal type gastric adenocarcinoma significantly decreases as the distance from the tumor node in-creases. Dysplastic changes are associated with epithelial hyperplasia, intestinal metaplasia, and inflamma-tory and atrophic changes. The results obtained support field cancerization and highlight the need to study morphological, molecular, and genetic alterations in the gastric mucosa adjacent to the tumor more deeply. The dysplastic changes present at the resection line area indicate that this fact must be considered when determining the resection line.
