- W202325752 abstract "A significant number of people suffer iatrogenic bile duct injury during laparoscopic cholescystectomy. Biliary-digestive bypass may be complicated by stenosis and biliary sepsis, affecting both quality of life and life expectancy. To avoid bypass synthetic grafts have been used, which are expensive.Evaluating autologous implantation of peritoneus as alternative of bile duct repair.Under general anesthesia, ten New Zealand adult rabbits were operated, common bile duct approached and sectioned underneath the cystic duct followed by a liver biopsy. An autologous graft was built of peritoneum and graft-bile duct proximal and distal end-to-end anastomosis done. Animals were followed-up by weekly bilirrubin and transferases. Rabbits were scheduled euthanized and a liver biopsy done for histological examinations.Autologous graft was easy to create and all rabbits survived. They did not develop jaundice or alterations in their normal habits. At necropsy, autologous grafts were removed and no signs of occlusion were noticed. Moderate short-term liver damage was observed but long-term damage was negligible. Bileoma and pyogenic liver abscess were observed in two animals, respectively.Our results favourably match well-known procedures used for bile duct repair, especially in cases of severe injury (Bismuth-Strasberg E1-3): it seems less complicated than biliary-digestive bypass, not as expensive as synthetic grafts, and much easier to build than human amnion graft.Interposing an autologous graft of peritoneum is an easy-to-create surgical procedure and circumferential bile duct injuries were adequately repaired.Antecedentes: un número significativo de individuos sufrirá daño por iatrogenia del colédoco durante colecistectomías laparoscópicas. Las derivaciones bilio-digestivas pueden complicarse con estenosis y sepsis biliar y afectar la calidad y expectativa de vida. Para evitar la derivación se utilizan injertos sintéticos. Objetivo: evaluar el implante autólogo de peritoneo en la reparación de colédoco. Material y métodos: estudio experimental efectuado en 10 conejos Nueva Zelanda adultos a los que se les resecó un segmento del colédoco y para la reparación término-terminal de la vía biliar se construyó un neo-conducto con peritoneo parietal como auto-injerto. Se vigilaron con ontroles semanales de bilirrubinas y transaminasas. A la necropsia programada se estudió el segmento injertado, se realizó biopsia epática durante el procedimiento y la autopsia. Resultados: los animales no mostraron alteraciones en sus hábitos normales, la herida quirúrgica no tuvo complicaciones, no cursaron con ictericia y a la necropsia el segmento injertado se apreció totalmente integrado. En dos animales hubo como complicación un bilioma y un absceso hepático. El daño hepático observado inicialmente fue disminuyendo a lo largo del seguimiento. Discusión: nuestros resultados se equiparan con ventaja con los métodos conocidos de reparación de vías biliares, especialmente en lesiones severas (Bismuth-Strasberg E1-3). Adolece de las complicaciones de las derivaciones bilio-digestivas, no es caro como los injertos intéticos y es de mucho más fácil construcción que el injerto de amnios humano. Conclusiones: el auto-injerto de peritoneo es un procedimiento adecuado como alternativa para tratar lesiones circunferenciales de colédoco." @default.
