A

60%

28

29
Q

gastric stasis (Roux stasis syndrome)
dumping syndrome
post-vagotomy diarrhea
Bile reflux gastritis
30
Q

What is a small gastric remnant?

A

One of the post-gastrectomy syndromes. Loss of gastric capacity or vagotomy resulting in loss of receptive relaxation / accommodation.

31
Q

what are the symptoms of small gastric remnant and what can you recommend for it?

A

early satiety, pain with eating, vomiting

–> small frequent meals, no fluid with meals

32
Q

What is gastric stasis (Roux stasis)?

A

One of the post-gastrectomy syndromes. Hypomotility of remnant stomach and motor disturbances in the jejunal limb.

33
Q

What are the symptoms of gastric stasis (Roux stasis) and what can you recommend for it?

A

Nausea, pain, gas/bloating, postparandial fullness, symptoms relieved by vomiting.
–> small frequent meals, liquids rather than solids, liquid calories and pureed foods, low fat, low fiber diet

34
Q

What is the dumping syndrome?

A

One of the post-gastrectomy syndromes. Loss of pyloric sphincter causes rapid influx of hyperpsmolar contents into the small bowel and releases of hormones (epinephrine) which affect GI motility.

35
Q

How soon after a meal does early dumping occur?

A

10-30 minutes after a meal

36
Q

What are the symptoms of early dumping syndrome?

A

epigastric fullness, N/V, abdominal cramps, nausea, diarrhea

37
Q

How soon after a meal does late dumping occur?

A

1-3 hours after a meal

38
Q

What are the symptoms of late dumping?

A

hunger, perspiration, tremors, difficulty concentrating

39
Q

What is postvagotomy diarrhea?

A

One of the post-gastrectomy syndromes. alterations in gastric emptying cause episodic explosive diarrhea unrelated to intake.

40
Q

What can you recommend for postvagotomy diarrhea?

A

watchful waiting (symptoms may improve over several months), avoidance of instigating foods, fiber supplement may be helpful, addition of antidiarrheal agents.

41
Q

MNT for dumping?

A

reduce concentrated sugars, test tolerance to lactose foods, eat protein rich foods with complex carbohydrates, drink 30 minutes before and after a meal (no liquid with meals), 5-6 smaller meals, chew foods well.

42
Q

What is bile reflux gastritis?

A

One of the post-gastrectomy syndromes. Most common after Billroth II. Results from chronic exposure of the gastric remnant to biliopancreatic secretions caused by loss of the pylorus.

43
Q

What are the symptoms of bile reflux gastritis?

A

burning epigastric pain, N/V that doesn’t relieve pain, pain only partially associated with meals, vomitus continuing bile mixed with food, possible weight loss and anemia.

44
Q

What can you recommend for bile reflux gastritis?

A

cholestyramine, antacids, histamine receptor blockers, proton pump

45
Q

T/F: Bone disease is common after gastritis?

A

True due to reduced intake of calcium and vitamin D-containing foods and malabsorption.

46
Q

Why does fat malabsorption occur after gastritis?

A

Due to alterations to gastric lipase and exocrine pancreatic insufficiency, cck release and SIBO
