Plummer vinson

34
Q

Risk factors of adenocarcinoma gastric cancer

A
  • Risk factors for gastric cancer:
    • a family history of gastric cancer
    • gastric ulcers
    • Helicobacter pylori
      • pernicious anemia
35
Q

Dx and tx of gastric cancer

A
  • DX: EGD (esophagogastroduodenoscopy) and biopsy showing gastric cancer
    • a CBC showing microcytic/hypochromic anemia
    • positive guaiac
  • Treatment = Radiation therapy and chemotherapy can be beneficial but the prognosis is poor
36
Q

3 causes of gastritis (heartburn/dyspepsia)

A

Autoimmune or hypersensitivity reaction

Infection (h. pylori)

Inflammation (NSAID or alcohol)

37
Q

How do NSAIDs cause gastric inflammation?

A

cause gastric injury by diminishing local prostaglandin production in the stomach and duodenum.

38
Q

Leading cause of gastritis

39
Q

How does pernicious anemia affect gastritis

A
  • Pernicious anemia: + schilling test + ↓ intrinsic factor and parietal cell antibodies
40
Q

What type of ulcer improves with food & which type worsens with foods?

A
  • Duodenal ulcer- pain improves with food*
  • Gastric ulcer- pain worsens with food
41
Q

Tx of hemorrhoids

A

Stool softeners Corticosteroid Sitz baths. Internal hemorrhoids=rubber band ligation

42
Q

Indirect hernia (MC type) is medial or lateral to inferior epigastric arteries

A

Medial = Direct

Lateral = Indirect

MDs Dont Lie

43
Q

Involves protrusion of the stomach through the diaphragm via the esophageal hiatus.

A

Hiatal hernia

44
Q
  • “skip areas” with transmural (full-thickness)
    • young adults (20-40) 2 to 3 times more common in Jews
    • Pathology: antibodies against intestinal epithelial cells.
    • Appearance leading to the typical “cobblestone”
45
Q

Complications of crohn’s disease

A
  • Obstruction, fistulas, abscesses, and perforation. Malabsorption of B12, megaloblastic anemia. ??Arthritis and uveitis??
46
Q

Tx of Crohn’s

Q

Tx of UC

A

Maintenance meds: sulfasalazine (Azulfidine®)

  • Mesalamine (Pentasa ® Asacol ®,) NSAIDs
  • Prednisone during flare-up
    • Antispasmodics only used for patients with frequent and troublesome diarrhea may precipitate Toxic Megacolon
50
Q

At what bili level is jaundice?

A

bilirubin > 2.5 mg/dl

51
Q

Causes of melena vs hematochezia

A

Melena: black tarry stool - upper GI bleed →Gastric cancer, duodenal ulcers, right-sided colon cancer, portal hypertension with esophageal varices, severe erosive esophagitis, Mallory-Weiss syndrome.

Hematochezia: bright red blood per rectum (BRBPR) - lower GI bleed → Hemorrhoids, anal fissures, polyps, proctitis, rectal ulcers, and colorectal cancer. Diverticulosis is generally an incidental finding, since diverticular bleeding is usually of greater volume.

52
Q

What is Courvoisier’s sign & what is the MCC?

A

describes an enlarged, palpable gallbladder in patients with obstructive jaundice caused by tumors of the biliary tree or by pancreatic head tumors. This kind of biliary obstruction evolves slowly.

MCC = Pancreatic carcinoma

Q

MC type of pancreatic carcinoma

A
  • Most commonly ductal adenocarcinoma located at the pancreatic head
54
Q

What type of carcinoma is virchows node seen in?

A

Pancreatic carcinoma

55
Q

Sx of pancreatic cancer

A
  • weight loss/epigastric abdominal pain, clay-colored stools
  • Jaundice + palpable non-tender gallbladder (Courvoisier’s sign)
  • Virchow’s node (or signal node) is a lymph node in the left supraclavicular fossa (the area above the left clavicle) that is associated with pancreatic cancer
56
Q

Dx of pancreatic cancer

A
  • ERCP
  • abdominal CT scan: 75% show tumor at the head of the pancreas, 25% at the tail
  • pancreatic Bx
  • abdominal MRI
  • elevated serum bilirubin
  • abnormal liver function tests
  • CA 19-9 is present in about 80% of patients who have pancreatic cancer
57
Q

Pancreatitis and a palpable epigastric mass

A

Pancreatic pseudocyst

58
Q

Study of choice for palpable epigastric mass presenting 2-3 wks after acute pancreatitis

A

CT scan is the study of choice → Pancreatic psuedocyst

59
Q

Pain worsens with which type of ulcer? Pain improves with which type of ulcer?

A

Duodenal ulcer (food classically decreases pain think Duodenum = Decreased pain with food)

Gastric ulcer (food classically causes pain)

60
Q

MCC of duodenal ulcer

A
  • Duodenal ulcers are most commonly caused by H. pylori (95%)
61
Q

Sx of gastric ulcer

A
  • Pain is described as gnawing or burning and usually radiates to the back
62
Q

The most common presenting symptom of a small bowel tumor is

A

abdominal pain- typically intermittent and crampy in nature

63
Q

Toxic megacolon

64
Q

Tx of toxic megacolon

A

Decompression of the colon is required

  • In some cases, colostomy or even complete colonic resection may be required
