Surgery Flashcards
differential for anterior mediastinal mass
4 T’s 1. Thymoma (normal bHCG, AFP)
- Teratoma (elevated bHCG, AFP)
- Thyroid neoplasm
- Terrible Lymphoma (normal bHCG, AFP)
scrotal mass that increases in size with valsalva…what is it and what is tx
Varicocele “bag of worms” -presents with subfertility, testicular atrophy -us finding of retrograde venous flow -dilation of pampiniform venous plexus tx: gonadal vein ligation, scrotal support, NSAIDS
how to confirm presence of peripheral artery disease
Ankle-brachial index
<0.9 abnormal (diagnostic of occlusive PAD)
0.91-1.3 normal
>1.3 suggestive of calcified and uncompressible vessels
treatment of gallstones
- Gallstones without symptoms
- Gallstones with typical biliary colic sx
- Complicated gallstone dz
- gallstones w/o sx –> no tx necessary
- gallstones with typical biliary colic sx –> elective laparoscopic cholecystectomy
- complicated gallstone dz (acute cholecystitis, choledocolithiasis, gallstone pancreatitis) –> surgery within 72 hours
physical exam findings indicative of a urethral injury
blood at the meatus, high riding prostate
pubic ramus fx, return of frank blood on foley insertion without resistance and NO blood at meatus
EXTRAperitoneal bladder rupture (contusion or rupture of the neck, anterior wall, or anteriorlateral wall of bladder
intra vs extra peritoneal rupture of the bladder
intra –> rupture of the dome of the bladder resulting in intraperitoneal leakage and presents with signs of chemical peritonitis (guarding, diffuse abd tenderness)
extra –> localized pain in lower abd and pelvis, pelvic fracture almost ALWAYS seen, gross hematuria present
most critical prognostic indicator of compartment syndrome
time to fasciotomy (go to OR right away…NO time for eval or elevation or ice)
-in fact, the leg should be kept at the level of the torso, not higher or lower
retropharyngeal abscess
presents with neck pain, odynophagia, and fever following penetrating trauma to the posterior pharynx. This infection can drain into the superior mediastinum. -If it extends through the alar fascia, it can enter the “danger fascia” and transmit infection into the POSTERIOR mediastinum and result in acute nectrotizing mediastinitis
ludwig angina
rapidly progressive bilateral cellulitis of the submandibular and sublingual spaces arising from an infected mandibular molar
succession splash over the epigastrum and a hx of acid ingestion several months ago in a suicide attempt
pyloric stricture = gastric outlet obstruction caused by mechanical obstruction leading to postprandial pain and vomiting and early satiety
-can be caused by gastric malignancy, crohns, PUD, ingestion of caustic agents
timeline of post-op fever
0-2 hours: prior trauma/infection, blood products, malignant hyperthermia
24hrs-1 week: nosocomial infection, noninfective (MI, DVT, PE), Group A strep, Clostridium perfringes
1 week-1 month: other bacteria not above, catheter infection, drug fever, dvt, pe
>1 month: viral infections, SSI (indolent organisms)
post-op fever defined as what temp
>100.4 = 38
tx of anal fissures
- topical anesthetics and nifedipine
- sitz bath
- high fiber diet and adequate fluid intake
- stool softeners
paradoxical chest wall movement
seen in flail chest with multiple rib fractures. Chest expands when inhales and retracts when exhale
colonic thickening and fat stranding, think what
ischemic colitis
persisting pneumo despite bilateral chest tube placement
think of tracheobronchial rupture secondary to blunt thoracic trauma. The right main bronchus is most commonly injured in these patients
-also may see pneumomediastinum or subq air
