Q

What are the radiological features of jejunal atresia?

A
  • Distended abdomen
  • Distended, air-filled bowel upstream to the area of atresia (so will have more distended bowel when compared to duodenal atresia)
  • Distal bowel is small and unused

Q

How can an inguinal hernia appear on xray?

A
  • Extensive distended bowel loops as obstruction in very low down in the bowel
  • A loop of bowel seen sitting too low - this is the part of bowel which has protruded out of the abdominal wall

Q

What is malrotation and volvulus?

A

Malrotation: incomplete rotation of the bowel during foetal development

Volvulus: a complication of malrotation where the bowel becomes twisted and the blood supply is cut off

16
Q

Where are the 2 normal fixed points of the bowel and where do they move to in malrotation?

A

1: Where the duodenum becomes the jejunum
2. At the appendix

In malrotation, the 1st fixed point is lower and to the right
The 2nd fixed point is higher and found next to the displaced 1st point

17
Q

What is the investigation of choice for malrotation and volvulus?

A

Upper GI contrast with follow through

18
Q

What are the radiological features of malrotation and volvulus?

A
  • NG tube inserting contrast into stomach, then into duodenum until point of twisting
  • Spiral is seen in duodenum at point of twisting
  • No contrast carried on past the twisting
19
Q

Why is malrotation and volvulus a lifethreatening condition?

A

Bowel twisting blocks the superior mesenteric artery, cutting off blood supply to the midgut

20
Q

How is a volvulus fixed in surgery?

A

The bowel is untwisted and put back in the abdomen in a safe place do that adhesions form and prevent re-twisting

21
Q

What happens if malrotation and volvulus is caught too late?

A

The bowel dies and the baby cannot be saved

this is why green bile is a red flag!

22
Q

Which of these conditions can cause perforation of the bowel?

  • Jejunal atresia
  • Duodenal atresia
  • Malrotation + volvulus
  • Meconium ileus
  • Inguinal hernia
  • Necrotising enterocolitis
A

Necrotising enterocolitis

23
Q

Which of these conditions is due to obstruction inside the lumen of the bowel?

  • Jejunal atresia
  • Duodenal atresia
  • Malrotation + volvulus
  • Meconium ileus
  • Inguinal hernia
  • Necrotising enterocolitis
A

Meconium ileus

24
Q

Which of these conditions is due to obstruction in the wall of the bowel?

  • Jejunal atresia
  • Duodenal atresia
  • Malrotation + volvulus
  • Meconium ileus
  • Inguinal hernia
  • Necrotising enterocolitis
A

Duodenal atresia

Jejunal atresia

25
Q

Which of these conditions is due to obstruction outside the wall of the bowel?

  • Jejunal atresia
  • Duodenal atresia
  • Malrotation + volvulus
  • Meconium ileus
  • Inguinal hernia
  • Necrotising enterocolitis
A

Malrotation + volvulus

Inguinal hernia
