  • Prominent small Bowel Loops
  • ?Small Bowel Atresia

FINDINGS:

  • X RAY ABDOMEN AP
  • USG ABDOMEN AND PELVIS
  • UPPER AND LOWER GI CONTRAST STUDY
  • Dilated air filled proximal small bowel loops with no evidence of air in distal loops
  • High density meconium in right iliac fossa.
  • Nasogastric tube tip in stomach.
  • Fluid filled distension of stomach & dilated proximal small bowel loops.
  • Intraluminal meconium in distal small bowel loops.
  • Upper GI study –No evidence of malrotation.
  • Lower GI study – Rectum filled with meconium, small caliber colon measuring 6 mm suggestive of  microcolon

DIAGNOSIS:

  • Mid-Distal Small Bowel Atresia and obstructi

TREATMENT:

Right upper quadrant laparotomy

  • Intestinal resection of  jejunoileal  atresia, end-back  intestinal Anastomosis  and intra-peritoneal drain insertion

POST OPERATIVE X RAY CHEST AP

  • Air noted in distal bowel loops.
  • Previously noted high density meconium seen in right iliac fossa is noted seen – passed out meconium.
  • Abdominal drain noted in central abdomen region.

HPE REPORT

DISCUSSION:

Jejunal Atresia

  • Jejunal atresia is due to an ischemic insult in utero.
  • Neonates present early with vomiting, abdominal distention, and failure to pass meconium.

 

  • Small bowel atresia is classified into four categories:

Apple peel jejunal atresia

  • There is initial obliteration of the SMA, resulting in jejunal atresia with a dorsal mesenteric defect.
  • The distal portion of the small bowel lies free within the peritoneal cavity and is tightly coiled around a vascular pedicle.
  • Abdominal radiographs typically show a triple bubble appearance of only a few dilated loops of bowel within the upper abdomen, with air-fluid levels seen on the cross-table lateral view

Ileal atresia 

  • Ileal atresia occurs due to an ischemic insult in utero.
  • Neonates typically present early in the neonatal period with vomiting, abdominal distention, and failure to pass meconium.
  • Management is with surgical repair.

Diffuse dilatation bowel loops, with a more dilated loop in the right mid abdomen No gas is seen within the rectum

Microcolon with contrast material passing retrograde to the level of the cecum and into the distal ileum

Massive focal dilatation of a loop of bowel within the mid and upper abdomen suggestive of obstruction secondary to atresia.

Differential diagnosis

  • Functional immaturity of the large bowel.
  • Meconium ileus
