1

Pulmonary sequestration diagnosis

CTA

2

Pulmonary sequestration most common location

Left lower lobe

3

Drainage system of extralobar versus intralobar pulm sequestration

Extralobar systemic
Inralobar pulmonary vein

4

Congenital lobar emphysema treatment

Lobectomy (no chest tube)

5

Most common lobation of CLE

Left upper lobe

6

Location of bronchogenic cyst

Mediastinum (right posterior to carina)

7

Treatment of bronchogenic cyst

Resection of cyst

8

Mediastinal masses: anterior, middle, posterior

Anterior: T-cell lymphoma, teratoma, germ cell tumors, thyroid cancer
Middle: T-cell lymphoma, teratoma, cysts (cardiogenic or bronchogenic)
Posterior: T-cell lymphoma, neuroblastoma, neurogenic tumor

9

Choledochal cyst types

I: Fusiform of entire CBD, tx resection and hepaticoJ

II: True diverticular cyst off CBD, tx resection

III: Distal dilatation involving sphincter or Oddi, tx resection and choledochoJ via duodenotomy

IV: Intra and extra hepatic cysts, tx resection and lobectomy, maybe transplant

V: Intrahepatic (Caroli's disease), tx lobectomy versus transplant

10

Neuroblastoma most common location

Adrenals, but can occur anywhere along sympathetic chain

11

Secretory diarrhea, raccoon eyes, hypertension, unsteady gait (opsomyoclonus), increased catecholamines, VMA, HVA, and metanephrines, in child <2 years old

Neuroblastoma

12

Embryological origin of neurblastoma

Neural crest cells

13

Indicators of worse prognosis in neuroblastoma

NSE (neuron specific elastase), LDH, HVA, diploid tumors, and N-myc amplification

14

Most common malignancies in kids

Overall: leukemia (ALL)
Solid: CNS tumors
Gen surg: Neuroblastoma if <2 yo; Wilms if >2 yo

15

Embryology of Meckel's

Persistent vitelline duct (aka omphalomesenteric duct)

16

Most common cause of painless lower GIB in kids

Meckel's

17

Pyloric stenosis metabolic abnormalities

Hypochloremic hypokalemic metabolic alkalosis

Tx: NS boluses until making urine, then switch to D5-NS with 10 mEq of K

18

Age of presentation for intususception

3 months to 3 years

19

Etiology of intestinal atresias

Intrauterine vascular accidents

20

Most common site of intestinal atresia

Jejunum

21

Associated abnormalities with duodenal atresias

Down's syndrome; cardiac, renal, and other GI abnormalities

22

TEF types

A: complete atresia

B: proximal fistula and distal atresia

C: most common, proximal atresia and distal fistula

D: Double fistula

E: H type just fistula

23

VACTERL Syndrome

Vertebral
Anorectal (imperforate anus)
Cardiac
TEF
Esophageal
Radius (thumb) or Renal
Limb

24

Approach to TEF repair

Right extrapleural thoracotomy

25

Malrotation diagnosis

Upper GI study: duo does not cross midline, duodenojejunal junction displaced to right

26

Treatment of Malro

Ladd procedure: resect ladd's bands, perform counterclockwise rotation (turn back hands of time), place cecum in left lower quadrant, duodenum in RUQ, appendectomy

27

Treatment of meconium ileus

Gastrograffin enema, test for CF

28

Appearance of abdominal x ray of meconium ileus

Dilated loops of small bowel without air fluid levels; ground glass or soap suds appearance

29

Classic presentation of NEC

Bloody stools after first feeding in premature neonates

30

Risk factors for NEC

prematurity
hypoxia
sepsis
