Flashcards in Diverticular Disease Deck (22):
How does diverticular disease occur.
Acquired outpouching of bowel mucosa secondary to high intraluminal pressures.
What part of the colon does diverticular disease most commonly affect.
Sigmoid and descending colon.
However, it can affect any part of the colon.
What is a possible cause of diverticular disease.
It has been postulated that it is secondary to low-fibre Western diets.
What does 'diverticulosis' mean.
It is the existence of diverticula with no inflammation.
What does 'diverticulitis' mean.
It is inflammation of a diverticulum.
What does 'diverticular disease' mean.
It is diverticula associated with abdominal pain and disturbed bowel habits.
What are the symptoms of diverticular disease. (5)
It largely depends on the site, severity and presence of complications.
Common symptoms include:
Abdominal pain (usually LIF).
Altered bowel habit.
What are the physical signs associated with diverticular disease. (4)
Guarding and rebound/percussion tenderness. (often in LIF).
Do a PR for localized tenderness/blood.
Who does diverticular disease usually affect.
Usually affects those over 50.
What is the prevalence of diverticular disease.
It occurs in 50% of patients over 50.
In what percentage of patients is diverticular disease asymptomatic.
It is asymptomatic in 95% of patients.
What does 'diverticular colitis' mean.
The term refers to crescenteric inflammation on the folds in areas of diverticulosis.
When does diverticulitis occur.
It occurs when faeces obstruct the neck of the diverticulum, causing stagnation and allowing bacteria to multiply and produce inflammation.
What are potential complications of diverticulitis. (5)
Bowel perforation (peridiverticulitis).
Abscess formation - usually pericolic.
Fistulae into adjacent organs - usually colovesical.
Acute rectal bleeding.
How is diverticular disease diagnosed in asymptomatic patients.
Incidentally on a colonoscopy or barium enema examination.
What can occur in sever diverticular disease.
Luminal narrowing in the sigmoid colon. This causes severe pain and constipation.
What part of the colon is most commonly affected in acute diverticulitis.
It most commonly affects diverticular in the sigmoid colon.
How does acute diverticulitis present. (6)
Severe pain in LIF.
Abdominal tenderness, guarding and rigidity on the left side.
Sometimes a palpable tender mass is felt in the LIF.
What term is used to describe the acute presentation of diverticulitis.
What is the differential diagnosis for a patient presenting with symptoms of diverticulitis. (4)
Inflammatory bowel disease.
Who is more likely to suffer a complication of diverticular disease.
Patients taking NSAIDs or aspirin.
