Q

Acute cholecystitis

- clinical presentation

A
  • Severe pain, RUQ but can start mid-epigastric. May also refer to right shoulder. Constant for >6 hours (vs. intermittent biliary colic)
  • RUQ TTP, + Murphy’s sign, guarding, rebound
  • Anorexia, malaise, n/v, fever
  • Signs of inflammation (leukocytosis, fever, etc.) and mild elevation of LFTs

Q

Biliary colic

- clinical presentation

A
  • Gallbladder neck is impacted by a gallstone
  • No inflammatory response
  • Pain (sudden, dull, colicky) d/t contraction of gallbladder against occluded neck. Usually RUQ, radiation to epigastrum or back
  • Pain usu precipitated by consumption of fatty food
  • Often n/v
  • Might pass stone, if it gets stuck in common bile duct: pancreatitis.
  • Need an US

Q

What w/u is needed to differentiate biliary colic from acute cholecystitis

A
- US
Inc. in cholecystitis:

Q

Choledocholithiasis

- clinical presentation

A
  • Cholecystitis but the stone is stuck in the duct and causing an obstruction
  • Severe epigastric pain, n/v, no blood, ill appearing, TTP in epigastric region, guarding and rebounding, no distention
  • Mild elevation of AST, ALT, alk phos (NOT bilirubin), elevated WBC
  • US: will show the stone

Q

Cholangitis

- clinical presentation

A
  • Medical emergency
  • Bacteria in duodenum ascends back into common bile duct, usu dt gallstone obstruction
  • Charcot’s triad: abd pain, fever, jaundice (also hypotension, mental confusion)
  • Can rapidly progress to septic shock, multiple organ failure
  • Dx: +WBC and CRP (inflammation), elevated LFTS
  • Tx: ERCP to remove stone, IV fluids, broad spectrum abx
21
Q

Acute pancreatitis

- clinical presentatino

A
  • Fever, anorexia, n, abd pain (severe and upper abdomen with radiation to back), no v/d
  • Elevated WBC, slight elevation of LFTs
  • Gross elevation of lipase and amylase
22
Q

Acute pancreatitis

- common causes

A
  • etoh
  • gallstones
  • elevated TG
23
Q

What is the purpose of the Ranson Criteria?

A

Help predict mortality related to acute pancreatitis. Used to help determine whether pt should be discharged home

24
Q

Mesenteric ischemia

- clinical presentation

A
  • *Medical emergency, don’t let the gut die!!
  • Ill appearing: diaphoretic, pain, severe distress (pain out of proportion to exam)
  • Elevated vitals
  • Abd: distended, TTP, rigidity, guarding, rebound tenderness
  • Possible reduced unilateral pulses to LE
25
Mesenteric ischemia | - dx testing
- WBC elevation | - CTA: reveals stenosis
26
Peptic ulcer disease | - Clinical presentation
- Burning epigastric pain - N/V - Vomiting red blood - Melanotic stool - Anemia - Perforation - Gastric outlet obstruction
27
Peptic ulcer disease | - signs of perforation or hemorrhage
- PE and lab signs of blood loss (volume depletion, decreased H&H, etc.) - Perf: Signs of free air in abdomen, usually hypotensive, worry for sepsis
28
Acute appendicitis - presentation - dx - tx
- periumbilical pain that localizes to McBurney's point - leukocytosis - Dx: CT is best, US if pregnant - tx: surgery
29
Mallory-Weiss tear - presentation - Dx - Tx
- Usu after bout of vomiting or retching - Increased risk if portal HTN - Usu middle-aged men who present with hematemesis, usually after vom or etoh - Dx: endoscopy - Tx: most stop bleeding spontaneously
30
Intussusception - clinical presentation - dx - tx
- MC: 3 months ot 6 years - M>F - Sudden, intermittent, colicky abd pain. Episodes of pain usu spontaneously resolve - Current jelly stool (late finding) - Lethargy, v, diaphoresis. No melena, HA, fever, hematemesis - Dx and Tx: air contrast enema o Will have coiled spring appearance o CI to air enema: perforation which needs surgical treatment
31
Incarcerated hernia | - clinical presentation
- Severe pain, usu acute onset - n/v - Inability to have a BM or bloody stool - signs of infection
32
Incarcerated hernia | - tx
- surgery | - not sure if she wants more details than this
33
Dont' forget
to read the required readings too!
34
workup for GI pain
- CBC - CMP - Lipase - UA - Preg test - cardiac enzymes - ECG - Flat/upright abd x-rays - KUB - CT - US
35
workup for Gi bleeding
- VITALS!!!! - CBC - PT/INR - PTT - BMP - Stool guiac - CTA/endoscopy
36
Workup for n/v/d without pain/bleeding
assess fluid volume
37
GI workup | - radiology
X-rays - Upright and supine: air-fluid levels, free air - KUB (upright chest, upright abdomen, and supine abdomen): gallstones, kidney stones, masses, perforations, obstruction - Lateral decubitus: eval for free air (pneumoperitoneum) * usually left side down
38
Lab and/or radiologic w/u | - cholelithiasis
- US - HIDA scan - ERCP (also removes the stones) - CBC: slight WBC elevation
39
Lab and/or radiologic w/u | - acute cholecystitis
- US: pericholecystic fluid (indicates acute not chronic) - HIDA scan: failure of isotope to appear in GB in 4 hours is high suspicious - Lipase
