Abstract
Introduction. Almost 60 years have passed since the first liver transplant performed by Thomas Starzl. During this time, medical technologies have gradually improved, which has made it possible to use more and more new methods and approaches in this type of medical care. One of the new techniques of recent decades is robotic surgery, which is gradually being introduced into medical practice, including in the field of transplant medicine.Objective. The purpose of writing this review was to summarize knowledge and describe the current status of development of robotic surgery in the aspect of liver transplantation, namely: liver resection in donors, as well as graft implantation in the recipient.Material and methods. The review includes foreign and domestic publications on minimally invasive donor liver surgery. Publications on the topic of robotic liver resection in the aspect of liver transplantation were also processed.Conclusion. Robotic surgery using advanced robotic systems represents the next step in the development of minimally invasive technologies in liver transplantation. Robotic systems provide more precise and dexterous control of instruments, allowing surgeons to perform complex procedures with greater precision and less risk to patients. However, the robotic approach is still very limited in geographical distribution and requires much more experience than laparoscopy. The upcoming introduction of new robotic systems that support haptic feedback or cavitronic ultrasonic surgical aspirators will further promote a widespread adoption of robotic liver resection in liver donors and liver recipients.

Abstract
The shortage of donor organs remains an unresolved issue in livertransplantation worldwide. Consequently, strategies for expanding the donor pool are currently being developed. Donors meeting extended criteria undergo thorough evaluation, as livers obtained from marginal donors yield poorer outcomes in recipients, including exacerbated reperfusion injury, acute kidney injury, early graft dysfunction, and primary nonfunctioning graft. However, the implementation of machine perfusion has shown excellent potential in preserving donor livers and improving their characteristics to achieve better outcomes for recipients. In this review, we analyzed the global experience of using machine perfusion in livertransplantation through the history ofthe development ofthis method to the latest trends and possibilities for increasing the number of liver transplants.

Abstract
Background Living donor liver transplantation (LDLT) is an effective treatment for patients with end-stage liver disease. This study was performed to evaluate the outcomes of the initial series of LDLT procedures performed in the Republic of Uzbekistan and to demonstrate that liver transplantation is viable under the conditions in this country. Methods Between October 2021 and December 2023, we performed 40 LDLTs. We evaluated both immediate and long-term outcomes. Results Thrombosis of the hepatic artery developed in one case (2.5%). Arterial anastomotic stenoses were diagnosed in three cases (7.5%) and were successfully treated with endovascular balloon vasodilation. Splenic artery steal syndrome arose in three patients (7.5%) and was managed with endovascular embolization of the splenic artery. One patient (2.5%) developed portal vein thrombosis. Portal vein stenosis occurred in two patients (5%) at 10 months posttransplantation and was addressed with endovascular balloon angioplasty, yielding good clinical outcomes. Biliary complications were observed in 45% of the cases, with bile leakages accounting for 89% of these issues and strictures of the biliary anastomoses for 11%. The in-hospital mortality rate was 12.5%. Conclusions Our research findings and analysis of complications align with the international literature, and the results are deemed acceptable during this implementation phase of the liver transplantation program. Accordingly, liver transplantation is feasible in the Republic of Uzbekistan; however, improvements in surgical and therapeutic methods are necessary to minimize the development of both early and late postoperative complications.

Abstract
Background. Living donor liver transplant is an effective method of treatment in patients with different types of endstage liver diseases. Unfortunately, patients undergoing such a complex treatment sometimes develop various vascular complications. Splenic artery steal syndrome has emerged as a cause of graft ischemia in living donor liver transplant recipients and may lead to high liver enzyme levels, cholestasis, hepatic artery thrombosis, and even a graft loss in some severe cases.Objective. Evaluation of the first results in the experience of our center with a routine intraoperative ligation of the splenic artery during the procedure of right lobe living donor liver transplantation in adult recipients for the prevention of the steal syndrome development in the postoperative period.Material and methods. Living donor liver transplant recipients with known hepatic arterial flow impairment were retrospectively studied. Patients were allocated into groups with regard whether the splenic artery had been ligated or not during the transplant procedure. Arterial complications were reviewed in both groups.Results. None of 30 patients with ligated splenic artery developed splenic artery steal syndrome after living donor liver transplant. splenic artery steal syndrome occurred in 60% patients with non-ligated splenic artery. Surgical technique of performing arterial anastomosis was not related to the splenic artery steal syndrome development (p<0.01 There was no local ischemic necrosis noted in the spleen in patients with the ligated splenic artery.Conclusion. Based on the analysis of our own experience and literature data, the splenic artery ligation appears to be an effective and safe method for preventing a splenic artery steal syndrome in patients following right lobe liver transplantation, with a minimal risk of ischemic complications for the spleen. However, further studies with larger sample sizes are needed to obtain more reliable results. Ultrasound examination and endovascular intervention are the primary tools for an early detection of abnormalities and rapid restoration of arterial blood flow in the hepatic artery of the graft.

Abstract
Biliary complications (BCs) are the most frequent complications following liver transplantation (LT). They are a major source of morbidity after LT. The incidence of BCs after LT is reported to range from 5% to 45%. The main post-LT biliary complications are strictures, biliary fistulas and bilomas, cholelithiasis, sphincter of Oddi dysfunction, hemobilia, and mucocele. Risk factors for biliary complications are diverse. In this article we seek to review the main types of biliary complications and modern approaches to their diagnosis and treatment.
