Flashcards in Pathoma 10.4 Stomach Deck (21):
1

Dx: Congenital malformation of the abdominal wall, leads to exposure of abdominal contents

Gastroschisis

2

Dx: Persistent herniation of the bowel into the umbilical cord; Failure of herniated intestines to return to the body cavity during development;

Omphalocele Covered by peritoneum and amnion (how you can tell the difference between omphalocele and gastroschisis)

3

Dx: Congenital hypertrophy of pyloric smooth muscle; Projectile vomiting; Visible peristalsis; Olive-like mass in abdomen More common in males

Pyloric stenosis

4

What is the treatment for pyloric stenosis?

Myotomy

5

Dx: Acidic damage to mucosa due to imbalances between mucosal defenses and acidic environment

Acute gastritis

6

A Cushing ulcer (increased intracranial pressure) is a risk factor for:

Acute gastritis Cushing ulcer (increased intracranial pressure) --> increased vagal stimulation

7

Chronic gastritis is what type of hypersensitivity reaction?

Type 4 T-cell mediated damage antibodies against parietal cells or intrinsic factor

8

Chronic gastritis involved what parts of the stomach?

Body and fundus if autoimmune (antrum if H. pylori) Knocking out parietal cells --> knocking out the ability to produce acid

9

Chronic gastritis is the most common cause of:

Pernicious anemia (B12 deficiency)

10

Patients with autoimmune chronic gastritis are at increased risk for

Gastric adenocarcinoma (from intestinal metaplasia)

11

Patients with H. Pylori chronic gastritis are at increased risk for what 3 things?

1. ulceration 2. gastric adenocarcinoma 3. MALT lymphoma

12

ZE syndrome causes:

Duodenal ulcers

13

Dx: Epigastric pain that worsens with meals

Gastric ulcer usually located on the lesser curvature of the antrum

14

T/F: Duodenal ulcers are almost never malignant.

True

15

What makes a gastric ulcer benign?

Small; punched out appearance; No heaping of mucosa around it or inflammation

16

What makes a gastric ulcer malignant?

Piling up of mucosa around the ulcer; large; irregular border

17

Nitrosamines, present in smoked foods, help explain the increased incidence of:

Gastric cancer (in Japan)

18

Dx: Signet ring cells infiltrate gastric wall; Linitis plastica; Not associated with H. Pylori, intestinal metaplasia or nitrosamines

Diffuse type of gastric cancer NO ulcers, instead diffusely thickened wall of stomach

19

Where does gastric cancer commonly spread?

Left supraclavicular node (Virchow node)

20

What is a Sister Mary Joseph nodule?

Distant metastasis of intestinal type of gastric carcinoma at the periumbilical region

21

A Krukenberg tumor is commonly seen with what cancer?

Diffuse type of gastric carcinoma distant metastases are bilateral ovaries
