Resolución de colección biliar gigante por fistulización espontánea al colon / Resolution of giant biliary collection by spontaneous colon fistulization

El tratamiento de las colecciones biliares puede consistir en actitud expectante con vigilancia radiológica del tamaño y las características de la colección, drenaje percutáneo guiado por pruebas de imagen (eco/TC), drenaje endoscópico dependiendo de la localización y la accesibilidad de la colección, o tratamiento quirúrgico. Se comenta el caso clínico de un hombre intervenido de forma programada realizándose una hepatectomía derecha, que presentó una colección adyacente al lecho quirúrgico, asintomática, sugestiva de bilioma, con aumento progresivo de tamaño, presentando de forma espontánea disminución hasta su resolución por fistulización al ángulo hepático del colon, confirmado por pruebas radiológicas. La formación de fístulas biliares al colon de manera espontánea se debe a la presión extrínseca de la colección sobre la pared intestinal con necrosis de la zona de contacto, siendo su presentación y documentación radiológica excepcionales

The treatment of bile collections is divided into: expectant attitude with radiological monitoring of the size and characteristics of the collection, percutaneous drainage guided by imaging tests (US/CT), endoscopic drainage depending on location and accessibility and surgical treatment. The clinical case of a man undergoing a scheduled hepatectomy was observerd, who presented a large asymptomatic subcapsular collection suggestive of bilioma, with progressive increase in size, spontaneously presenting a decrease until its resolution by fistulization to the hepatic angle of the colon confirmed by Radiological findings. The spontaneously formation of biliary fistulas to the colon is due to the extrinsic pressure of the collection on the intestinal wall with necrosis of the contact zone, being its presentation and radiological documentation exceptional
