Flashcards in GIped Deck (27):
1

most common type of esophageal atresia

Type A(87%; EA and distal TEF)

2

frothing and bubbling at the mouth and nose; cough; cyanosis; respiratory distress; feeding exacerbates symptoms

TEF

3

Dx of TEF

inability to pass an NGT or OGT in the NB is suggestive

4

Management of TEF

maintain patent airway; prone position; esophageal suctioning; surgical ligation of TEF and primary end-to-end anastomosis of the esophagus

5

most common esophageal disorder in children of all ages

GERD

6

major mechanism in GERD allowing reflux to occur

transient LES relaxation

7

main stimulus for transient LES relaxation

gastric distension (straining; coughing; large volume or hyperosmolar agents)

8

Dx of GERD

Barium study of esophagus and upper GIT; esophageal pH monitoring; endoscopy; Radionuclide scintigraphy with Tc

9

Management of GERD

conservative therapy; lifetstyle modification

10

management for intractable GERD

fundoplication

11

physiologic strictures in the esophagus

cricoid cartilage; tracheal bifurcation; EG junction

12

type of necrosis caused by liquid alkali

liquefaction necrosis

13

type necrosis caused by acidic agents

coagulative necrosis

14

management of caustic ingestion

upper endoscopy; dilution by water/milk; surgical resection

15

intrinsic causes of intestinal obstruction

atresia; stenosis; meconium ileus; aganglionic megacolon

16

extrinsin causes of intestinal obstruction

malrotation; constricting bands; intra-abdominal hernias; duplications

17

classic symptoms of intestinal obstruction

nausea/vomiting; abdominal distention; obstipation

18

most common cause of nonbilious vomiting

pyloric stenosis

19

firm; moveable; olive-shaped mass; visible gastric peristaltic wave after feeding

pyloric stenosis

20

bulge on the pyloric muscle into the antrum in barium study of pyloric stenosis

shoulder sign

21

streaks of barium in the narrowed channel in pyloric stenosis

double tract sign

22

diagnostic tests for pyloric stenosis

UTZ is confirmatory(pylorus>4mm or length >14mm; barium studies

23

Tx for pyloric stenosis

Ramstedt pyloromyotomy

24

twisting of a loop of intestine around its mesenteric attachment site (usually sigmoid and cecum)

volvulus

25

triad of volvulus

Sudden onset of severe epigastric pain; inability to pass a tube in the stomach; retching with emesis

26

bird's beak sign; inverted U sign; coffee bean sign

volvulus

27

Tx of volvulus

derotation and decompression; laparoscopic derotation or laparatomy +/- bowel resection
