Q

mgmt rectovaginal fistual

A

IBD related:

  • asx: observe
  • mild: cipro/flagyl
  • mod to severe: Infliximab first! (any anti-tnf)…only if persistent dz then surgery

Non-IBD: surgery

20-30% crohns pt will develop anorectal fistula

Q

Mgmt post corrosive ingestion

A
  • CXR and abdominal xray will identify perforation
  • if no perf on xrays, early EGD w/in first 24 hours to assess and grade esophageal involvement

acute mgmt does not have role for barium swallow (can ID strictures later)

No NG insertion b/c can induce perforation

Q

common complications of Roux-en-y

A
  1. Stomal Stenosis (20%): n/v/abdominal pain/early satiety. Dx EGD. Tx endoscopic balloon dilation
  2. Cholelithiasis (40%): give prophy URSDA for up to 6 mo post op
  3. Dumping syndrome (50%): abdominal pain, n, hypotension, reflex tachycardia. Avoid by replacing simple carbs for complex carbs
  4. SIBO: abdominal distention, flatulence, diarrhea. macrocytic anemia. fat malabsorption (D, A, B1, b12).

Patient with + serology or highly suggestive need endoscopy with biopsy (“small bowel enteroscopy”) to confirm dx PRIOR to starting gluten-free diet (reduces biopsy sensitivity). A cutaneous bx showing dermatitis herpetiformis is also diagnostic.

PIE: Odynophagia (painful)…and retrosternal CP
PIE is PAINFUL IF EATING

Neither need EGD routinely.

For EE: dietary modifications, swallowed fluticasone/budesonide (topical glucocorticoid). Eval includes 8 week trial of a PPI

125
Q

Treatment of Hep B

A

Main drugs (pick one):

  • Entecavir
  • Tenofivir
  • PEG Interferon is an option with limitations (ok if pregnant, CI if cirrhosis, major depression, autoimmune disorders, severe cytopenias)
  • If HIV also: Emtricabine-Tenofivir
  • Don’t treat in immune tolerant phase (AKA normal LFTs despite high DNA level)
126
Q

How do you differentiate phases of Hep B?

A

Immune tolerant: normal ALT despite +HBeAg and high HBV DNA. *No tx indicated

Inactive carrier stage: +HBeAg and HBV DNA <20,000. *No tx indicated

Chronic Phases:
Immune active: HBeAg +, elevated ALT and HBV DNA >10,000
or
Immune escape: HBeAg -, elevated ALT and HBV DNA>10,000
(Escape is without the E)

Reactivation phase: HBeAg negative, ALT up, HBV up

127
Q

Chronic SBP prophylaxis

A

Use fluoroquinolone (cipro) in:

  • any hx of SBP
  • high risk: ascitic protein < 1.5 + any of Na <130, bili >3, Cr >1.2, BUN>25
  • while hospitalized if ascitic protein <1
  • for 7 days if active bleeding (variceal)

A

AMI: Usually from afib/ambolus. Acute severe pain. Need angiography. Likely need an intervention or surgery/embolectomy.

Ischemic colitis: usually mild to moderate, painless hematochezia will bring patients in. Low flow states or vasoconstricting meds. Don’t need angiography, dx with colonoscopy. Tx with bowel rest and observation, usually no intervention.

139

No, but high risk people do:

  • black >20 years old
  • asian men >40, women >50

Tx of HCV

A

Sofosbuvir and ledipasvir (or other vir drugs).

stop if bili doesn’t improve by day 10

Dont use if GI bleed, infection, kidney dz or pancreatitis

fasting serum transferrin saturation

ferritin can be elevated in advanced liver disease but can have normal iron sat
