Objective:

The objective of the study was to evaluate whether a diagnosis of choledocholithiasis established by imaging (ultrasonography, Tomography or colangioresonance) reduces the risk of complications after ERCP.

Materials and methods:

We included the files of the patients who underwent ERCP in the endoscopy service of the Adolfo López Mateos Regional Hospital during the period from January 2015 to December 2017. We filled out a data collection sheet for each patient and they concentrated for their analysis in the SPSS program. All ERCPs that were not general surgery were removed. 136 were discarded, leaving a total of 286 patients.

Results:

Only complications occurred in 38 patients (13.3% of total ERCP included), most of which (30 patients, 78.9% of complicated patients) were from the group that entered the procedure without a diagnosis of choledocholithiasis, while of the group with previous diagnosis, there were only 8 patients (corresponding to 21.1%) of the patients with complications. Performing the Pearson P analysis based on square Chi is significant (0.003).

Conclusions:

In our study, it was shown statistically significant that having imaging diagnosis of choledocholithiasis prior to ERCP reduces the risk of complications associated with the procedure. We also describe the percentage of complications 13.3% in our center that comparatively to the world literature is slightly higher than the one reported in the international literature that varies according to the demography between 1 and 10% of the total of cases.
