    Abstract

    Today, hepatitis B virus-associated acute liver failure remains the leading cause of liver failure (44% mortality in Asia and 41% in the United States). Studies show that among patients with hepatitis B-associated cirrhosis, acute liver failure develops in 10-20% of cases. Acute liver failure on chronic liver disease is a potentially reversible syndrome that occurs in patients with cirrhosis or chronic liver disease and is characterized by acute decompensation, organ failure, and high short-term mortality. Chronic hepatitis B virus infection is a leading cause of liver morbidity and mortality worldwide. When we talk about hepatitis B, there is a high risk of developing super infection hepatitis D, since hepatitis D remains infectious and can reactivate at very low titers that are not detected using modern analysis methods if HBsAg remains in the blood serum. The interaction of these viruses leads to accelerated progression of fibrosis and cirrhosis of the liver, which significantly increases the risk of developing acute liver failure against the background of chronic.

    In our case, a patient diagnosed with liver cirrhosis as a result of viral hepatitis B with delta agent, class C according to Child–Pugh–Turcotte, MELD-36 points, the patient developed a severe form of acute renal failure, which required emergency intervention, so he was not included in the waiting list for a transplant from a cadaveric donor. His wife became the donor, which is an example of living donation, which provides higher chances of successful recovery due to a shorter waiting time and a lower risk of graft rejection. Timely examination of the donor and recipient, as well as prompt liver transplantation, contributed to a favorable outcome of the disease.

    Abstract

    Pancreatoduodenectomy is the only treatment method for patients with pancreatic head and periampullary region tumors. It is known that some long-lived patients develop exocrine pancreatic insufficiency after surgery. One of the consequences of exocrine pancreatic insufficiency is fatty liver disease, which has been reported to occur in 7.8% to 40.0% of patients after pancreatoduodenectomy. We reported two clinical cases of patients who underwent pancreatoduodenectomy and total pancreatectomy for pancreatic head cancer and intraductal papillary mucinous neoplasm of the main pancreatic duct. After surgery, they developed rapidly progressive fatty liver disease with no history of liver disease, leading to death from liver failure 20 days and 3 months after surgery. Severe malnutrition caused by exocrine pancreatic insufficiency, postoperative eating disorders, and exacerbation of diabetes mellitus were the main factors contributing to the rapid deterioration of the condition. This clinical case highlights the possibility of developing life-threatening fatty liver disease with severe fibrosis after pancreatoduodenectomy and total pancreatectomy. Careful monitoring of liver status, regular nutritional assessment of patients, prophylactic replacement of pancreatic enzymes, and ensuring adequate nutrition are important.

    Abstract

    Background. Bile duct injury is a potentially life-threatening condition characterized by high morbidity and mortality, which occurs as a result of erroneous manipulation during surgical intervention, such as incorrect identification of the ducts, improper clipping, or thermal injury. The aim of the study is to investigate the effectiveness of laparoscopic hepaticojejunostomy in patients with post-cholecystectomy bile duct injuries and compare it with traditional open techniques. Materials and

    Methods. A retrospective analysis of the results of laparoscopic and open hepaticojejunostomy in patients with bile duct injuries from 2017 to 2023 was conducted.

    Results. Laparoscopic surgery was performed on 28 patients, while open surgery was performed on 57 patients. Statistically significant differences were noted in the presence of external biliary fistula, diameter of the anastomosis, duration of the operation, postoperative complications, and postoperative period. There were no significant differences in the frequency of intraoperative complications.

    Conclusion. The laparoscopic approach in treating bile duct strictures classified as Strasberg E1 - E2 is safe and effective.
