2. Based upon the location of this pain, would you guess that the organ in
question is a retroperitoneal organ or an organ attached to the abdominal
wall by a broad sheet of mesentery? Explain your answer. - answer-2.
Chronic exposure to alcohol can cause pancreatitis - - i.e. inflammation of
the pancreas. Since the pancreas is a retroperitoneal organ, the dull,
throbbing pain associated with pancreatitis is often felt in the back. It is
therefore likely that Vincent is suffering from alcohol-induced pancreatitis.
The destruction of exocrine cells in the pancreas reduces this organ ability
to secrete digestive enzymes and HCO3- ions into the duodenum during
meals. Consequently, many of the nutrients in Vincent's meals will never be
completely digested, and therefore never absorbed into the bloodstream.
Vincent will slowly lose weight due to this malabsorption syndrome.
2
shown to lower the lower esophageal sphincter pressure, and it is probably
a major contributing cause of Vincent's reflux esophagitis. And in Vincent's
case, the reflux esophagitis is exacerbated by his repeated alcohol-drinking
binges and bouts of vomiting.
2. Where are esophageal varices typically located? (Be specific.) - answer-
2. Esophageal varices are usually located in the lower end of the
esophagus, where veins of the portal circulation (i.e. veins ultimately
draining blood through the portal vein of the liver) anastomose with veins of
the systemic circulation (i.e. veins ultimately draining blood into the superior
and inferior venae cavae).
, 3. Based upon the function of the organ in question, what is causing the
"steatorrhea" and weight loss? - answer-3. Since many of the nutrients
Vincent ingests during a meal pass through the intestines unabsorbed, they
osmotically draw water from the bloodstream into the intestinal lumen,
causing an "osmotic diarrhea." The high fat content of the stool gives it a
foul odor and yellowish color - - a condition called steatorrhea. The inability
of Vincent to absorb the nutrients of his meal will cause him to slowly lose
weight. This malabsorption syndrome can now be treated with the ingestion
of pancreatic enzymes with each meal.
3. Can you think of any treatments for Vincent's problems? Explain the
mechanisms for those treatments, based upon your knowledge of the
regulation of gastric secretions. - answer-3. Treatments for reflux
esophagitis include the following:
A. Avoid exposure to substances that reduce lower esophageal sphincter
pressure, such as alcohol, caffeine, cigarette smoke, and chocolate
B. Avoid large meals (i.e. over-distension of the stomach)
C. Avoid strenuous activity or lying down for the first two hours following a
meal
D. Use antacids, which directly neutralize the gastric acid in the stomach
lumen
E. Use H2-blocking drugs, which block the stimulatory effect of histamine
on the gastric glands and therefore decrease gastric acid secretion
F. Use drugs that directly increase the lower esophageal sphincter
pressure (e.g. cisapride), making it more difficult for gastric contents to
reflux into the esophagus
G. Use H+ ion pump blockers (e.g. omeprazole), which directly inhibit
gastric acid secretion by the stomach lining
Many of the treatments listed here are helpful in the treatment of gastritis
and peptic ulcers as well. However, if it is determined that Vincent has a
peptic ulcer, he should be placed on two weeks of antibiotic therapy to
destroy the bacterium Helicobacter pylori, which is implicated in most
ulcers.
3. If Vincent's liver disorder resulted in the production of a "gallstone," what
danger might that present for his pancreas? - answer-3. A gallstone
expelled from the gallbladder can be force by peristaltic contractions down
through the cystic and common bile ducts. If it gets lodged and stuck near
the ampulla of Vater, it could partially or completely block not only the flow
