The aim of investigation: to assess the possibilities of diagnostic and therapeutic BAE in a multidisciplinary hospital.Materials and Methods: The analysis of the findings was carried out in 32 patients who underwent 40 diagnostic and 17 therapeutic procedures. Small bowel ulcers were detected in 6 patients, angioectasias in 5. One patient with subcompensated jejunal stricture in the suprastenotic section was found to have a bezoar foreign body. In 17 patients, tumors of a different nature were identified: carcinoids in 4, gastrointestinal-stromal tumors (GIST) in 6 patients, adenocarcinomas in 7 patients. One patient was diagnosed with varicose veins of the jejunum, complicated by bleeding. In 9 patients, polyps of the jejunum and ileum were identified. Reoperations were planned in 6 patients.Results: When conducting therapeutic balloon-assisted enteroscopy, the following types of endoscopic treatment were used: endoscopic clipping (angiectasia-4 and ulcers-2), argon plasma coagulation was used in 1 case, endoscopic polypectomy was performed in 9 patients, destruction of the bezoar with a diathermic loop and balloon dilatation strictures in one case. Patients who had a pathology that was not subject to endoscopic treatment were operated on.Conclusion: The availability of modern equipment significantly expands the capabilities of clinicians in the differential diagnosis of pathological conditions of the small intestine and allows for minimally invasive treatment, shortening the rehabilitation period due to the reduction of surgical trauma.

Peutz-Jeghers syndrome is a genetic disorder inherited in an autosomal dominant pattern and characterized by a mutation in the STK11 gene. According to domestic literature, the risk of inheriting this pathology from a parent to a child is 50%. According to WHO data, in 2018, more than 74,000 new cases of colorectal tumors were detected in the Russian Federation, with 5–10% of cases being hereditary syndromes, of which 1% is Peutz-Jeghers syndrome. The frequency of occurrence is approximately 1/29,000–1/120,000.  The aim of the work is to share the experience of diagnosing and treating a patient with Peutz-Jeghers syndrome. Today, we have the ability to timely diagnose pathological changes in the mucous membrane of the small intestine, perform minimally invasive treatment, reducing rehabilitation time due to a decrease in surgical trauma.

The article presents a clinical case of massive recurrent bleeding from angioectasias of the jejunum in a 66-year-old patient. Within 13 months in the conditions of the GBUZ KKB No. 2, Krasnodar, the patient underwent: 1 video capsule examination of the small intestine, 3 esophagogastroduodenoscopy, 3 colonoscopy, 3 balloon-assisted enteroscopy. At the place of residence, the patient repeatedly underwent blood transfusions, as well as endoscopic examinations of the upper and lower parts of the digestive tract. In our facility, the patient underwent diagnostic laparoscopy, and twice-resection of the jejunum area that carries vascular malformation.

The aim of the study is to observe a patient with vascular malformation of the ileum complicated by recurrent bleeding. Materials and methods: the article presents a clinical case of small intestine bleeding from ileum angiectasia in a 64-year-old patient. At the patient's place of residence, a video capsule endoscopy of the gastrointestinal tract was performed, angiectasia of the ileum was detected, from which fresh blood was received. Upon admission, the patient has iron deficiency anemia, and hematocheesia. In our institution, the patient underwent diagnostic egophagogastroduodenoscopy, video colonoscopy, balloon-assisted enteroscopy (BAE). According to BAE, vascular malformation with a diameter of up to 10 mm is viuzalized in the ileum Results: The patient underwent endoscopic treatment: one endoclypse was applied to the identified vascular malformation. Conclusion: The capabilities of clinicians in the differential diagnosis of pathological conditions of the small intestine are enhanced by the availability of modern equipment in medical and preventive institutions, as well as to perform minimally invasive treatment, reducing the rehabilitation time due to the reduction of surgical trauma.
