- type and time of last meal or other oral intake (information required if surgery is indicated)
- past medical and surgical history, medication use, and family history.
28
In what order should the physical examination be done?
Measure vital signs: blood pressure, temperature, and pulse rate.
- Inspection-Make a general assessment of how ill the patient appears.
- Auscultation-chest and abdomen
- Percussion
- Palpation
- Other important examinations: rectal, pelvic, scrotal/testicular
29
Why do you do auscultation before palpation?
to put the patient at ease and increase cooperation
also palpation may stimulate bowel activity and thus falsely increase bowel sounds if performed before auscultation

49
What is biliary colic?
it is defined as pain in the abdomen, due to obstruction usually by stones in the cystic duct of the biliary tree
50
What is the pain caused by in biliary colic?
due to contraction
51
What is causing it to contract in biliary colic?

there is RUQ pain
there is no fever or jaundice
62
Is there RUQ pain, fever or jaundice with cholecystitis?
there is RUQ pain and fever
no jaundice
*jaundice is present in 10% of cholecystitis cases
63
Is there RUQ pain, fever or jaundice with cholangitis?
there is RUQ pain, fever and jaundice
64
How does a patient with biliary colic present?
steady severe pain in the RUQ
symptoms last between 15mins and 5h
65
How does a patient with cholecystitis present?
biliary pain lasting more than 5 hours accompanied by features of inflammation e.g., fever, marked RUQ tenderness, leukocytosis
66
How does a patient with cholangitis present?
sudden onset epigastric or LUQ pain whicvh may radiate to the back, nausea and vomiting common causes are gallstones and excessive alcohol consumption
67
Would you expect inflammation in biliary colic?
No
68
Why is there jaundice with cholangitis?
bilirubin would not secreted from the liver, so you would have jaundice
elevation of LFT (aka elevated liver enzymes)
69

obesity
aging
oestrogen treatment
pregnancy
diabetes
75
What are risk factors for pigment gallstones?
haemolytic anaemia
black pigment gallstones form whenever an increased load of bilirubin reaches the liver
76
What is the general pathogenesis of gallstones?
there is supersaturation
gallstones made of water, bilirubin and salts
Imbalances in the constituents of bile and biliary sludge secondary to gallbladder hypokinesis can lead to the precipitation of insoluble stones. When these gallstones cause physical blockages in the biliary tree and beyond, pain, inflammation, and infection can result in damage to the gallbladder and a host of other organs.
77
What are some complication caused by gallstones?
gallstone pancreatitis
acute cholecystitis
causing biliary obstruction
gallstone ileus
biliary fistula
bouveret syndrome
mirizzi's syndrome
78
What is Mirizzi's syndrome?
Mirizzi's syndrome is a rare complication in which a gallstone becomes impacted in the cystic duct or neck of the gallbladder causing compression of the common hepatic duct, resulting in obstruction and jaundice.
defined as common hepatic duct obstruction caused by extrinsic compression from an impacted stone
79
What is bouveret syndrome?
Bouveret syndrome refers to a gastric outlet obstruction secondary to impaction of a gallstone in the pylorus or proximal duodenum. Thus, it can be considered a very proximal form of gallstone ileus.
80
What do impacted gallstones in the cystic duct cause?
acute cholecystitis
81
What is gallstone ileus?
it is an uncommon cause of a mechanical small bowel obstruction
*small bowel ileus is different to bowel ileus
82
When does gallstone ileus occur?
when stone obstructs ileocecal valve after migrating through the fistula
83

A fistula is an abnormal connection between two body parts, such as an organ or blood vessel and another structure
84
What are types of biliary fistula? (5)
Cholescystoduodenal
