Summary
Biliary complications after liver transplantation are common, often requiring endoscopic or percutaneous procedures. Surgical intervention is reserved for cases where less invasive methods fail, with hepatic artery thrombosis increasing complication rates.
Area of Science:
- Hepatology
- Transplant Surgery
- Gastroenterology
Background:
- Biliary reconstruction is a critical challenge in liver transplantation, associated with significant postoperative complications.
- Biliary strictures and leakages are common issues following liver transplant procedures.
Purpose of the Study:
- To identify risk factors for biliary strictures and leakages post-liver transplantation.
- To evaluate the efficacy of different treatment methods for biliary complications.
Main Methods:
- Retrospective analysis of 182 liver transplant patient records from 2001-2015.
- Evaluation of demographic data, transplantation type, biliary reconstruction methods, and vascular/biliary complications.
- Assessment of treatment outcomes for biliary complications, including interventional procedures and surgery.
Main Results:
- Biliary complications occurred in 26.92% of patients, with strictures (15.38%) and leakages (7.7%) being most frequent.
- Hepatic artery thrombosis was significantly associated with biliary complications (20.4%; p=0.003).
- Endoscopic/percutaneous procedures were primary treatments, with surgery reserved for failures; success rates were 45% for non-surgical and 61.9% for surgical interventions.
Conclusions:
- Biliary complications are frequent after liver transplantation and necessitate further interventions.
- Endoscopic and percutaneous approaches are initial treatments, followed by surgery if necessary.
- Hepatic artery thrombosis is a contributing factor to increased biliary complications.

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...
