[Transparieto-hepatic dilation of benign biliary stenosis: 5 years experience].
OBJECTIVE
To assess the results of percutaneous transparieto-hepatic dilation of benign biliary stenosis achieved over a period of 5 years.


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


METHODS
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.
