RESUMEN
The most frequent type of benign bile duct stricture (BBDS) that complicates surgery, is not an indication for placement of any current model of metal stent because of poor long-term results. This statement could not apply to less frequent types of BBDSs, in particular those complicating chronic pancreatitis (CP) and radiotherapy. The authors report their preliminary results observed in 10 patients whose CP-related BBDS was treated with an Ultraflex Diamond stent. No stent dysfunction was detected in the observed patients during a mean follow-up of 17 months. Studies involving larger numbers of patients followed for longer periods of time are necessary to know whether endoscopy using this material may replace surgery in this indication.

OBJECTIVE: The purpose of this study is to report a new sign, "acinar filling," observed on dynamic MR pancreatography after secretin stimulation in patients with suspected early chronic pancreatitis. CONCLUSION: Acinar filling might reflect tissue hypertension or loss of pancreatic parenchyma compliance or both. This finding is probably an insensitive but specific sign of early chronic pancreatitis.
