Q 
1. Absorption of fat is defective when
destroyed by disease or resection of
a. Duodenum
b. Jejunum
c. Ileum
d. All of the above
A

c. Ileum

Lipolysis is completed in the duodenum and
jejunum by pancreatic lipase, which is
inactivated by a pH <7.0. (19th ed., p1935)

Q
  1. Similar bet. GI TB & Crohn’s. EXCEPT.
    A. Caseating granuloma
    B. Lymph node involvement
    C. Fistula
A

A. Caseating granulomaThe earliest lesions are aphthoid ulcerations
and focal crypt abscesses with loose
aggregations of macrophages, which form
noncaseating granulomas in all layers of the
bowel wall (19th ed., p1952)

Q 
4. Malabsorption can be expected after
Bilroth II operation because
A. part of the pancreas is resected
B. Mucosa of small bowel is destroyed
C. Length of small bowel is reduced
D. Stasis at the afferent loop
A

D. Stasis at the afferent loop
Although rarely seen today as a result of the
decrease in the performance of Billroth II
anastomosis, two types of afferent loop
syndrome can occur in patients who have
undergone this type of partial gastric
resection. (19th ed., p1926)

Q
  1. Racecadotril anti-diarrheal mechanism?
A 
Racecadotril increases the availability of
endogenous opioids (enkephalins) by
inhibiting the membrane-bound
enkephalinase. The enkephalins in turn
mediate their effect through δ receptor
activation that induces a selective increase
in Cl absorption by inhibiting adenylate
cyclase.
