Introduction:

Since Dr. McCune, in 1966, described for the first time the endoscopic retrograde cholangiography (ERCP) procedure, a great interest in improving the procedure was awakened.There are several attempts to understand the factors that make the selective cannulation of the bile duct difficult, among these efforts we have the elaboration of classifications based on the macroscopic aspect of the duodenal papilla and attempts to relate the type of anatomical classification with the difficulty of the procedure, this in order to reduce the comorbidities associated with the difficult bile duct E Haraldsson publishes in 2017 a classification based on the morphology of the váter ampule; The purpose of this work is to correlate the morphology with the canulation technique chosen by the operator.

Objectives:

To know if the morphology of the vater ampule modifies the cannulation technique in ERCP.

Material and methods:

Retrospective, observational, transversal and descriptive study. By means of a bibliographic review, the data referring to the morphology of the ampule and the cannulation technique used in CPRES carried out at the UMQ Juárez Centro from 03/01/2018 to 03/01/2019 were compiled on an Excel sheet (Office Professional 2016).

Results:

150 reports were analyzed, of which 64 were classified as type 1 (42.6%), 61 type 2 (40.66%), 18 type 3 (12%) and 7 type 4 (4.66%). 85.9%, 39.34%, 50% and 71.4% of the ampoules classified as type 1, type 2, type 3 and type 4, respectively, were channeled by conventional techniques, as well as 14.06%, 60.66%, 50% and 28.6% of the Amps classified as type 1, type 2, type 3 and type 4, respectively, were canalized using advanced techniques.

Conclusions:

It was observed that the majority of type 1 ampules were cannulated by conventional techniques, unlike type 2 ampules which were cannulated mostly by advanced techniques.
