Presentation
5 days old term baby with history of no bowel motion since birth and progressive abdominal distension associated with bilious aspirate from the gastric tube.
Patient Data
Progressive gaseous distension of the small bowel with no gas seen in the distal bowel/colon. No pneumoperitoneum is seen.
Multiple dilated fluid-filled bowel loops in the lower abdomen.
Small/unused colon. Free flow of contrast from the rectosigmoid colon to the cecum with contrast reflux into the normal-appearing terminal ileum.
Histopathology of the resected bowel (ileum) showing intestinal atresia.
Case Discussion
The patient underwent laparotomy.
Operation notes: Approximately 7 cm long atretic segment in the ileum, 45 cm from the ileocecal valve, associated with localized volvulus and proximal small bowel dilatation. No bowel perforation seen. The affected segment was resected with primary anastomosis.
The patient developed a second episode of small bowel obstruction after two weeks; see case (rID-167064).
