[ERCP success after 72 hours of pre-cut].

INTRODUCTION: Despite the advances of bile duct catheterization, its success is still not guaranteed. Few studies have been published regarding a second ERCP attempt, however those reports enhance the catheterization success Objective: To determine whether an ERCP performed 72 hours after a first precut papillotomy enhances the bile duct catheterization.

MATERIAL AND METHODS: A cohort study was performed including all patients that had ERCP with precut papilotomy without catheterization of the bile duct and 72 hours later were programmed to a new ERCP between September 2015 and September 2016. These patients did not have any distinctive characteristic such as age, gender or anatomy that were associated with the failure to catheterize the bile duct, compared to the general population.

RESULT: 16 patients were included with a mean age of 61,3 years (SD: 10,6), bile duct catheterization was successful in 14 cases. No complications presented after precut papilotomy. Both failures went to surgery.

CONCLUSIONS: Our experience about an 87% successful bile duct catheterization, 72 hours after precut papillotomy allows us to suggest it as an alternative before considering surgery.
