A

combo therapy for 2-3 weeks:

Q

.best test for PUD and why

A

upper endoscopy b/c its more sensitive and definitive

differeniates gastritis from ulcer disease;

all gastric ulcers need repeat endoscopy to document healing

Q

.disadvantage of PUD tests:

barium radiography,

serum antibody test

stoot antigen testing,

urea breath test

A

barium radiography: cheap but less sensitive, 30% false neg rate

serum antibody test: highly sensitive but cannot be used to confirm cure

stoot antigen testing and urea breath test: s and s but not accurate for 4 weeks after completion of treatment

Q

.what gender is gastrin adenocarcinoma twice as common in

age

incidence

A

males

usually over 40 y/o

common cancer worldwide but less common in US

38
Q

.gastrin adenocarcinoma strongly associated with what

what decreases risk

A

h pylori

asa, nsaids, wine, lots of fruits/veg

39
Q

progressive dysphagia vs postprandial vomiting in terms on gastrin adenocarcinoma

A

progressive means the neoplasm is impinging on esophagus and postprandial means its near the pylorus

40
Q

metastatic spread of gastrin adenocarcinoma

A

left supraclavicular lymphnode(virchows node) and umbiliical node(sister mary joseph node)

41
Q

common finding in gastrin adenocarcinoma

other tests

A

iron def anemia

liver enzymes may be elevated with hepatic metastases

endoscopy with cytology should be done a pt with 40 years of age with dyspepsia who is unresponsive to therapy

do CT after to determine the extent of the disease

42
Q

what is the common extra-nodal site for non hodgekins lymphoma

A

stomach

43
Q

what is the risk of gastric lymphoma if H pylori is present

A

6 fold!

44
Q

.what is ZES

results in what

% of cases of PUD from this

A

gastrin secreting tumor resulting in excessive acid production; causes hypergastrinemia

results in refractory PUD

1% of cases of PUD are caused by ZES

45
Q

most gastrinomas found where

A

in pancreas and duodenum;

but may be found anywhere or may metastasize

46
Q

.presentation of ZES

A

similar to PUD and maybe…

abdominal pain may have secretory diarrhea that improves with H2 blockers or PPI

occult or frank bleeding, causing anemia

47
Q

presentation of gastric adenocarcinoma

A

dyspepsia and weight loss associated with anemia and occult GI bleeding

progressive dysphagia may be caused by a neoplasm impinging on the esophagus

postprandial vomiting may be caused by a neoplasm near the pylorus

48
Q

advantage of early diagnosis of gastric adenocarcinoma

A

80% cure rate;

if the muscularis propria is involved, the cure rate is 50%

but is there is lymphatic spread, the cure rate is 10%

49
Q

progressive dysphagia or postprandial vomiting

A

think gastric adenocarcinoma

dyspepsia and weight loss associated with anemia and occult GI bleeding

progressive dysphagia may be caused by a neoplasm impinging on the esophagus

postprandial vomiting may be caused by a neoplasm near the pylorus

50
Q

tx of gastric adenocarcinoma

A

curative or palliative resection of tumor

chemo or radiation may provide some palliative benefit

51
Q

.carcinoid tumors in stomach location

A

55% occur in GI tract, 30% in lungs

rarely occur in response to hypergastrinemia and are generally benign and self limited

52
Q

gastric lymphomas incidence

risk

sx

dx

tx

A

less than 2% of gastric malignancies

risk is greater by 6 fold if h pylori present

sx same as gastric adenocarcinoma

dx: findings differ than adenocarcinoma only in the pathology of the lesion
tx: resection with or w/out radiation or chemo

53
Q

stomach the most common extranodal site for what

A

non hodgkin’s lymphoma

54
Q

discuss type A and type B in chronic gastritis

A

type A(10%) occurs in fundus and d/t autoantibodies to parietal cells. causes pernicious anemia and assoc with other autoimmune disorders and increased risk of gastric adenocarcinoma and carcinoid tumors

type b(90%) occurs in antrum and may be caused by NSAIDs or h pylori infection. often asymptomatic, but assoc with increased risk of PUD and gastric cancer.

55
Q

why is type A gastritis assoc with pernicious anemia

A

due to lack of intrinsic factor necessary for the absorption of vitamin B12

56
Q

stress ulcers and burn injuries

A

curling ulcers;

associated with traumatic brain injury

57
Q

h pylori antibodies after an infection

A

they stay positive even when cleared;

use the urea breath test or a repeat stool antigen as a test of cure

58
Q

.risk factors for gastric cancer (3)

A

diet high in nitrates and salt; low in fresh vegetables

h pylori colonization (90%)

chronic gastritis

59
Q

.what to do if you suspect a perforation with PUD

A

get a KUB upright to evaluate diaphram and CT abdomen

60
Q

.how to remember ulcer pain after a meal

A

after a meal, pain from a GASTRIC ulcer is GREATER

whereas DUODENAL pain DECREASES

61
Q

misoprostol

A

can help pts with PUD who require NSAID therapy

62
Q

1) hypercalcemia (MEN type 1)
2) epigastric pain(peptic ulcer)
3) diarrhea (due to mucosal damage and pancreatic enzyme inactivation leading to malabsorption)

A

3 key things about ZES

64
Q
