27
Q

Malrotation and abnormal rotation in
utero which results in incomplete fixation of the small bowel.

Ladds Bands develop between the cecum and peritoneum, which compresses the duodenum and causes obstruction.

A

Volvulus

28
Q

Midgut Volvulus is twisting of the small bowel containing the _________ _________ artery, quickly leading to ischemia

A

Superior Mesenteric Artery

29

30
Q

A

Volvulus

31
Q

Will you see gas distally to duodenum on abdominal plain films in a volvulus pt?

A

NO!

air fluid levels in the stomach and duodenum only
NO GAS DISTALLY TO DUODENUM BECAUSE IT IS TWISTED

32
Q

Tx for volvulus?

A

Emergency surgery

33
Q

Motor disorder of the gut
congenital absence of ganglion cells in the distal rectum and colon
causes an aganglionic segment, which leads to obstruction

male:female ratio is 3:1
sometimes associated with down syndrome

A

Hirchsprungs disease

34
Q

S/S
Failure to pass Meconium (first stool) within 72 hours of life
Explosive expulsion of gas and stool after digital rectal exam (SQUIRT SIGN)

Signs of bowel obstruction:
Vomiting, bowel distention, failure to pass stool, megacolon, fever

A

Hirschsprungs Dz

35
Q

How do you diagnose Hirschsprungs disease?

A

Rectal biopsy!!

(supported by abdominal xrays, contrast enema or anorectal manometry)

36
Q

Tx= surgery

resect the affected bowel segment, bring normal ganglionic bowel down close to the anus to preserve sphincter function

A

Hirschsprungs disease

37
Q

MC congenital anomaly of SMALL INTESTINE*

incomplete obliteration of the vitelline duct, leading to a true diverticulum of the small intestine

(these are uncommon and often not picked up til adulthood)

A

Meckel’s Diverticulum

38
Q

Rule of 2s:

Occurs in 2% of population
Male:Female ratio of 2:1
Within 2 feet of iliocecal valve
Can be 2 inches long
Usually present before age 2

A

Meckel’s Diverticulum

39
Q

S/S:

Painless GI bleeding, due to ulceration of small bowel
Children with intussesception or recurrent intussesception
Signs of sm bowel obstruction- abdominal pain, vomiting

A

Meckel’s Diverticulum

(sometimes Meckel’s can cause intussuscpetion)

40
Q

How do you diagnose Meckel’s diverticulum?

How do you treat?

A

Meckel’s scan!! (nuclear medicine)

Tx with resection (surgery)

41
Q

Invagination of a part of the intestine itself
MC abdominal emergency in children under 2 yo

Suddent onset of intermittent severe abdominal pain epsiodes
inconsolable crying
*DRAWING LEGS/KNEES TOWARD THE ABDOMEN

A
