Hello and welcome to the Zero to Finals podcast. My name is Tom and in this episode I'm going to be talking to you about acute coliciditis.

And you can find written notes on this topic at zero definals.com acute coliciditis or in the general surgery section of the zero

Goal stones may be trapped in the neck of the gallbladder or in the cystic duct.

In a small number of cases, the dysfunction in the gallbladder emptying is caused by something other than gallstones, and this is called acalculus colostitis.

One scenario that may cause a calculus colicestitis is where patients are on

total parental nutrition or are having long periods of fasting, for example when they're in the

intensive care unit for another very serious condition, and the gallbladder is not being stimulated by

food in order to empty regularly, and this causes a build-up inside the gallbladder. Remember that

normally the gallbladder is stimulated by a chemical called colostocycinocyanin, which is released in

response to food in the duodenum.

If there's no food entering the GI tract because the patient is on total parental nutrition

or fasting, then the gallbladder is not receiving this stimulation, so bile builds up in the

gallbladder and can lead to acalculus colostitis.

Let's talk about the presentation of acute colostitis.

The main presenting symptom of colostitis is pain in the right upper quadrant.

This may radiate to the right shoulder.

Other features include fever, nausea, vomiting,
