Abstract
Objective

To assess the results of percutaneous transparieto-hepatic dilation of benign biliary stenosis achieved over a period of 5 years.

Design

A retrospective study to assess the technique, complications and the clinical, analytical and radiology results.

Patients

Data was gathered on 13 patients diagnosed in our Hospital between the years 2002 and 2006 with benign biliary stenosis and who had been treated using percutaneous dilation. Patients diagnosed with malignant disease and those who had a prosthesis were excluded. Seven of the patients had received a liver transplant. One patient had an endoscopic dilation on two occasions, with the stenosis persisting.

Results

A clinical and radiological improvement was observed in 60% of the cases, and an analytical improvement in 69% (61% normal). Re-stenosis occurred in 30% of the cases, of which 50% were rescue support using re-dilation. The complications presented (30.7%) were resolved conservatively. No significant differences were observed between the transplanted and the non-transplanted groups.

Conclusions

Transparieto-hepatic dilation of benign biliary stenosis is a fairly safe technique and has a high rate of resolution in the medium term, and avoids the use of surgery in 75% of patients. The results need to be confirmed in larger samples.

Resumen
Objetivo

Valorar los resultados de la dilatación percutánea transparietohepática de las estenosis biliares benignas durante un período de 5 años.

Diseño

Estudio retrospectivo para evaluar la técnica, las complicaciones y los resultados clínicos, analíticos y radiológicos.

Pacientes

Se recogieron datos de 13 pacientes diagnosticados de estenosis biliar benigna que se trataron mediante dilatación percutánea en nuestro centro entre los años 2002–2006. Se excluyó a los pacientes diagnosticados de enfermedad maligna y a aquellos pacientes a los que se les colocó una prótesis. Siete de los pacientes han sido receptores de trasplante hepático. Un paciente había recibido dilatación endoscópica en 2 ocasiones con persistencia de la estenosis.

Resultados

Se comprobó mejoría clínica y radiológica en el 60% de los casos y analítica en el 69% de los casos (el 61% de normalización). El 30% de los casos presentó reestenosis, de los que el 50% fueron subsidiarios de rescate mediante redilatación. Las complicaciones que se presentaron (30,7%) se resolvieron de forma conservadora. No se observaron diferencias significativas entre el grupo de trasplante y el grupo sin trasplante.

Conclusiones

La dilatación de las estenosis benignas de la vía biliar por vía transparietohepática es una técnica bastante segura, tiene una alta tasa de resolución a medio plazo y permite evitar la cirugía en más de un 75% de los pacientes. Los resultados deben confirmarse en muestras mayores.
