Acquired ileal atresia in infancy: report of two cases

Acquired Jejunal Atresia in a 2-Month-old Infant

Acquired intestinal atresia in non-necrotizing enterocolitis affected patients is very rare. We report a 2 month old male infant who presented with bilious vomiting, abdominal distension and constipation. He was exclusively breast fed, gained weight and was asymptomatic till six weeks of age. Exploratory laparotomy revealed blind-ended, dilated proximal segment and collapsed distal segment of jejunum at approximately 30 cms from duedeno-jejunal flexure, with a V-shaped mesentery defect resembling a type III-a congenital jejunal atresia.

Acquired ileal atresia induced by adhesive intestinal obstruction

Three female infants, aged 13, 7 and 18 mo respectively with acquired ileal atresia induced by adhesive small bowel obstruction are reported. Case 1 was diagnosed with urachal cyst and cyst excision was performed when she was 7-mo-old. Case 2 was diagnosed with mesenteric cyst and cyst excision was performed by laparoscopic-assisted procedure when she was 3-mo-old. Case 3 had no history of abdominal operation previously. At laparotomy ileal atresia induced by adhesive band was found.

Under pressure: a contribution to the pathogenesis of acquired ileal atresia

An acquired ileal atresia is a rare occurrence. A 3-week-old neonate is presented, who developed postnatally a type 2 ileal atresia and an ileal stenosis within a pre-existing internal hernia secondary to an adhesion band. The literature reports a total of eight cases (4 females) with acquired ileal atresia in babies ranging in age from 3 weeks to 2 years (median 4 months). Mechanical forces (eg, adhesion band, intussusception and volvulus) onto the intestine are most frequently (75%) implicated as the primary event. The distal ileum is most often affected and a type 3A atresia is identified in six of eight (75%) cases.
