Flashcards in Ch. 330.3 - Malrotation Deck (22):
1

Malrotation is INCOMPLETE rotation of the intestine during fetal development and involves intestinal non rotation or incomplete rotation around the ___

SMA

2

Intestinal rotation and attachment begins when

5th week of gestation

3

Abdominal rotation and attachment are completed by ___

12th week of gestation

4

Normal configuration of organs after rotation

Duodenum at the region of the LOT, colon at the LUQ, cecum at the RLQ

5

Configuration of organs in the abdominal cavity in nonrotation

1st and 2nd portions of duodenum in the normal position, remainder of duodenum, jejunum, and ileum on the right, colon on the left

6

MC type of malrotation

Failure of cecum to move to the RLQ in the sub hepatic area

7

Bands of tissue that can extend from the cecum to the RUQ, crossing and possibly obstructing the duodenum seen in malrotation

Ladd bands

8

T/F Malrotation and non rotation are often associated with other abnormalities of the abdominal wall

T

9

GI anomaly associated with asplenia

Malrotation

10

Majority of malrotations present within

1st year of life

11

>50% of malrotation presenting in the 1st year of life present during

1st month of life

12

MC symptom of malrotation during infancy

Vomiting

13

Approximately 25-50% of patients with malrotation in this age group are asymptomatic

Adolescents

14

A life-threatening complication of malrotation, which resembles an acute abdomen or sepsis and is the main reason that symptoms suggesting malrotation should always be investigated

Volvulus

15

Radiograph may demonstrate a gasless abdomen or evidence of duodenal obstruction with a double-bubble sign

Volvulus

16

Gold standard in the evaluation and diagnosis of malrotation and volvulus

UGIS

17

Normal intestinal rotation is seen on UGIS as

1) Duodenal C-loop crossing the midline 2) Duodenojejunal junction located to the left of the spine

18

Best exam to visualize malposition of the LOT

UGIS

19

Positioning of superior mesenteric vessels seen on UTZ that can suggest malrotation

SMV located to the left of the SMA

20

Recommended management for any patient with a significant rotational abnormality REGARDLESS OF AGE

Surgical intervention: Ladd procedure

21

T/F Purpose of surgical intervention in malrotation is to return organs to normal configuration

F, To minimize the risk of subsequent volvulus

22
