Non-OB Abdominal Pain Flashcards
How may appendicitis present in pregnancy?
RUQ pain may be higher d/t displaced GI system
What is the effect of progesterone?
smooth muscle relaxation –> decreased LES tone and peristalsis and increased intestinal transit time
appetite stimulant
What contributes to N/V?
- hCG
- estrogen
- elevated T4
- altered motility
- reflux
- emotions/psych
How do sodium and albumin levels change?
mildly decreased serum levels
How does hematocrit change?
moderately decreased blood levels –> physiologic anemia
How do serum bile acids, cholesterol, and triglyceride levels change?
mildly increased serum levels
ruptured ectopic
location, character, radiation, dx
location: lower abdomen, pelvis
character: localized, severe
radiation: none
dx: serum hCG, abdominal U/S
PID
location, character, radiation, dx
location: lower abdomen, pelvis
character: gradual onset, localized
radiation: flanks and thighs
dx: abd U/S
appendicitis
location, character, radiation, dx
location: periumbilical –> RLQ (RUQ in late pregnancy)
character: gradual onset –> focal
radiation: back, flank
dx: abd U/S, elevated WBCs
acute cholecystitis
location, character, radiation, dx
location: RUQ
character: focal
radiation: right scapula, shoulder, or back; middle of back
dx: abd U/S = thickened gallbladder wall, serum LFTs
pancreatitis
location, character, radiation, dx
location: epigastric
character: localized; deep, piercing, midline
radiation: middle of back
dx: (2 out of 3) clinical presentation, abd U/S = pancreatomegaly (CT better), serum lipase and amylase
perforated peptic ulcer
location, character, radiation, dx
location: epigastric or RUQ
character: burning, deep, piercing
radiation: right back
dx: abd U/S, laparotomy, H. pylori?
urolithiasis
location, character, radiation, dx
location: abdomen or flanks
character: intermittent, aching to severe, unremitting
radiation: groin
dx: abd U/S, urinalysis,, occasional fluoroscopy w/ contrast urography
What are abd pain red flags?
1) N/V after 20wks
2) hematemesis
3) blood in diarrhea, stool
4) jaundice
What labs should be ordered for abd pain?
1) CBC w/ diff
2) LFTs (alk phos normally elevated; ALT & AST same)
3) Cr > 1.1 = concerning
4) BMP (Na 129-143 = normal - low = concerning!)
5) amylase & lipase (lipase = better)
6) UA
What is the preferred dx test in pregnancy for abd pain?
abd U/S
What effect does pregnancy have on cholelithiasis?
- increased cholesterol synthesis
- gallbladder hypomotility
What is the most common cause of jaundice during pregnancy?
acute viral hepatitis
What are 2nd and 3rd trimester differentials for jaundice?
2nd: drug hepatotoxicity and gallstone disease (e.g. acute cholecystitis, gallstone pancreatitis)
3rd: intrahepatic cholestasis of pregnancy, acute fatty liver of pregnancy, HELLP syndrome
What are differentials of RUQ abdominal pain?
pain characteristics important
pain + abnormal LFTs + new onset HTN = preeclampsia w/ hepatic involvement
What are differentials of RLQ pain?
GI d/o: appendicitis, Crohn’s, intussusception, colon cancer, IBS
OB/GYN: ruptured ectopic, ovarian tumor/cyst rupture/torsion, endometriosis, uterine leiomyomas
renal: nephrolithiasis, cystitis
What are differentials of N/V?
hyperemesis gravidarum
pancreatitis
cholelithiasis
peptic ulcer disease
acute fatty liver of pregnancy
HELLP
Describe presentation of cholestasis
- pruritus in third trimester
- no hx chronic liver disease
- absence of abdominal pain
- affects hands and feet
- mild to mod elevated serum transaminase and bili levels
What is the most common non-obstetric surgical emergency in pregnancy?
appendicitis
