1

when is excisional biopsy contraindicated

when histopathologic disease process of the mass in UNKNOWN

2

needle core biopsy method

obtained percutaneously or openpneumatic vs spring filled vs manualsmallleast invasiveprone to crush

3

disadvantages of needle core biopsy

small size/qualityprone to crushinaccurate tissue collectionhemorrhageseeding of tumor cells

4

US guided liver biopsy recommendations

needle core biopsyat least 2 cm away from vascular structures33% get skeletal muscle

5

reported lateral thermal damage in liver biopsy w harmonic scalpel

1.3 mm

6

recommendations for endoscopic GI biopsy sample #

stomach 6-8SI 10-15LI 3-4

7

T/Fendoscopic biopsy can ddx btwn inflm vs neoplasia in bowel of cat

FALSEcan NOT ddx btwn IBD vs LSA in catsneed full thickness biopsy

8

target sampling of renal biopsies

CORTEX

9

T/Frenal biopsy by novice endoscopist were superior to US guided biopsies

TRUEless artifactincr glomerulifewer inappropriate tissue samples

10

major complication following renal biopsy

hemorrhage

11

risk factors associated with open renal biopsy complications

agelow body weightsevere azotemia

12

methods for bone biopsy

Jamshidi closed needle (smaller, lower diagnostic quality)Michelle Trephine (better quality, risk fx)

13

methods of lung lobe biopsy

pre tied loop ligatures (2 cm biopsies obtained)TA staplerendoscopic staplers

14

T/F harmonic scalpel use in spleen led to less hemorrhage when compared to standard techniques Vt Sx 2006 Barnes et al

FALSE incr inflam/fibrous CT in pancreas/spleendid NOT control hemorrhage from spleen as wellcoagulation necrosis evident in sample but diagnostic quality achieved
