Objective. To estimate a high-frequency welding of the living tissues as a variant of treatment for the Barrett’s esophagus. Materials and metods. Retrospective analysis of the treatment results was conducted in 73 patients, suffering Barrett’s esophagus, in 36 of whom the argon-plasm coagulation was performed (Group I), while in 37 (Group II) - a high frequency welding of living tissues. Into the investigation the patients with a short-segment Barrett’s esophagus C2-3M3-4 (the Prague Classification, 2004 yr) and a high-grade dysplasia without a nodule development (VI World Congress of International Society for Diseases of the Esophagus (ISDE) were included. Results. In patients of Group I a severe esophageal edema have occurred in accordance to endoscopic ultrasonography data. In this Group in 5 (13.89%) patients after performance of the argon-plasm coagulation esophageal stenosis was observed, corrected by application of the balloon dilation. In 8 (22.22%) patients of this Group the disease recurrence have occurred, necessitating performance of additional séance of the argon-plasm coagulation. In patients of Group II the above mentioned inflammatory signs were less pronounced, and mucosal regeneration have proceeded more rapidly, than in patients of Group I - during 53 and 115 days, accordingly. The disease recurrence was noted in 2 (5.41%) patients of Group II only. Conclusion. High-frequency welding of living tissues constitute a safe and effective method of treatment in patients, having esophageal metaplasia.

Today, thanks to the development and implementation of new modern instrumental research methods in the daily practice of doctors, such as computed tomography with angiography, multispiral computed tomography, ultrasound examination of vessels with duplex scanning, celiacography, upper and lower mesentericography, etc. Every year, the information content of the above examination methods is growing, which will certainly lead to an increase in the frequency of detecting rare vascular pathologies that cause hemobilia. The method of treatment for this vascular pathology is endovascular embolization using embolizing coils and substances. A clinical case of a multidisciplinary approach to diagnosis and endovascular treatment is presented. a. gastroduodenalis with the formation of a pseudo-aneurysm (40 × 20 mm) with antegrade blood flow along a.pancreaticoduodenalis superior and a.gastroepiploica dextra distal to the aneurysm of a 28-year-old patient who was urgently hospitalized in the surgical department of Kyiv Regional Clinical Hospital. After the surgical treatment against the background of conservative treatment, the patient’s general condition improved and the hemoglobin level increased. A multidisciplinary approach helps to choose the right tactics for managing a patient, even with such a rare vascular pathology that has led to hemobilia. The gold standard for diagnosis and treatment hemobilia is angiography and endovascular embolization, which can be an alternative to open surgery, minimizes the risk of postoperative complications and reduces the rehabilitation period. If it is impossible to carry out the above technique or its ineffectiveness, further treatment is surgical.
