1. A biliary diagnostic system comprising:
an output device configured to provide at least one of an audio output and a visual output;
a tubular body extending from a proximal end portion to a distal end portion for insertion into a duodenoscope, the tubular body comprising:
an outer wall extending between the proximal end portion to the distal end portion; and
an internal lumen extending at least partially through the tubular body between the proximal end portion and the distal end portion to form a working channel opening to an exterior of the tubular body at the proximal end portion;
non-transitory computer readable medium having stored therein one or more magnitudes of a first parameter for an electrical property of liver bile;
a first biliary diagnostic sensor coupled to the tubular body, the first biliary diagnostic sensor comprising a first electrode configured to analyze biological matter in contact with the tubular body to sense a magnitude of an electrical property of the biological matter and determine presence of liver bile using the first parameter;
wherein the non-transitory computer readable medium further has stored therein instructions executable by a processor to perform a method comprising:
comparing the magnitude of the electrical property sensed with the first biliary diagnostic sensor to the one or more magnitudes of the first parameter for the electrical property of liver bile;
generating a first output signal for the output device indicative of a first type of stone sensed by the first biliary diagnostic sensor if the sensed magnitude of the electrical property is greater than the first parameter, wherein the first output signal causes the output device to activate in a first manner, wherein the first output signal provides an output indicative of the first type of stone, wherein the first type of stone comprises a kidney stone; and
generating a second output signal for the output device indicative of a second type of stone sensed by the first biliary diagnostic sensor if the identified electrical property is less than the first parameter, wherein the second output signal causes the output device to activate in a second manner different from the first manner, wherein the second output signal provides an output indicative of the second type of stone, wherein the second type of stone comprises a gall stone; and
a first auxiliary device configured to perform a first type of procedure for the first type of stone; and
a second auxiliary device configured to perform a second type of procedure for the second type of stone
wherein:
the first auxiliary device comprises a forceps; and
the second auxiliary device comprises a sphincterotome.
