Pt ingests radiolabeled meal.
Scans taken at 0, 1, 2, 4 and 6 hours
tests for dysmotility disorders
What is Manometry? When is it used?
Pressure sensitive device is placed in the stomach and duodenum, and measures the contraction of the GI system.
Used if dysmotility is confirmed with other means
What are the results of a Manometry with neuropathic problems?
Contraction of normal amplitude, but abnormal contractile patter
What are the results of a Manometry with myopathic
Low average amplitude of contraction
What are the ROME II criteria for IBS?
1. Relieved by defecation
2. Onset associated with change in stool frequency
3. Onset associated with a change in stool form or appearance
What is IBS?
Recurrent abdo pain for at least 3 days during the previous 3 months and associated with 2 of the criteria
What are the supporting symptoms of IBS?
1. Altered stool frequency
2. altered stool form
3. Altered stool passage
5. Abdo bloating or distension
What is IBS-D?
What is IBS-C?
What is IBS-M
Mixed diarrhea and constipation
What is IBS-A?
Alternating diarrhea and constipation
True or false: it is common that IBS pts change type within a year
What are the pmhx flags for IBS?
Onset of abdominal pain and altered bowel habits in childhood
The development of IBS symptoms in people older than what age should prompt a closer search for an underlying organic cause?
40 years old
What is the key to diagnosing IBS?
What are the "alarm" symptoms of IBS (5)
-Nocturnal diarrhea or pain
The focus of an evaluating a pt with suspected IBS is what?
rule out organic disease prior to dx IBS (e.g. lactose intolerance, gluten intolerance)
Fatty stool indicates what?
Infectious or absorptive problem

Lower or LLQ
What is the pain like in IBD?
Dull pain with intermittent sharp pain.
What does eating/defecation do to the pain in IBS?
Eating = precipitate
Defecate = improves
