Replacement of the main bile duct by bioprosthesis in an experimental porcine model (24-month results)
Background
Cholecystectomy for conditions like iatrogenic injury during cholecystectomy can lead to complications such as bile duct injuries, necessitating alternative options like bioprosthesis.
Methods
This study evaluated a bioprosthesis’s efficacy in maintaining bile duct continuity over 24 months in 16 male pigs.
Results
The bioprosthesis was implanted in the common bile duct of three-month-old animals, with follow-ups at 1, 6, 12, 18, and 24 months. Liver function remained stable, and biliary permeability was assessed through various imaging techniques. Despite mild stenosis, biliary flow was unimpeded. Histological analysis confirmed biliary epithelium presence in the regenerated area.
Conclusion
The bioprosthesis acted as a scaffold for tissue regeneration without compromising biliary function. Remnants of the bioprosthesis were observed but did not affect biliary excretion in the 24-month porcine model. This study highlights the bioprosthesis’s potential in bile duct reconstruction, offering a safe and effective option for maintaining biliary continuity.
期刊介绍：
HPB is an international forum for clinical, scientific and educational communication.
Twelve issues a year bring the reader leading articles, expert reviews, original articles, images, editorials, and reader correspondence encompassing all aspects of benign and malignant hepatobiliary disease and its management. HPB features relevant aspects of clinical and translational research and practice.
Specific areas of interest include HPB diseases encountered globally by clinical practitioners in this specialist field of gastrointestinal surgery. The journal addresses the challenges faced in the management of cancer involving the liver, biliary system and pancreas. While surgical oncology represents a large part of HPB practice, submission of manuscripts relating to liver and pancreas transplantation, the treatment of benign conditions such as acute and chronic pancreatitis, and those relating to hepatobiliary infection and inflammation are also welcomed. There will be a focus on developing a multidisciplinary approach to diagnosis and treatment with endoscopic and laparoscopic approaches, radiological interventions and surgical techniques being strongly represented. HPB welcomes submission of manuscripts in all these areas and in scientific focused research that has clear clinical relevance to HPB surgical practice.
HPB aims to help its readers - surgeons, physicians, radiologists and basic scientists - to develop their knowledge and practice. HPB will be of interest to specialists involved in the management of hepatobiliary and pancreatic disease however will also inform those working in related fields.
