Enteric duplication can induce intestinal obstruction in neonates. We evaluated the pathogenetic mechanism of neonatal bowel obstruction related to enteric duplication in three of our own cases and in cases reported in the Japanese literature.
Case 1: A 3,540 g full-term female neonate was referred to us on Day 3. Emergency laparotomy was performed and an enteric duplication measuring 5 cm in diameter was found in the ileocecum. The ileum had invaginated into the cecal fossa, which caused an internal hernia. Case 2: A 3,544 g full-term male neonate was referred to us on Day 2. Emergency laparotomy was performed and two enteric duplications measuring 0.7 cm and 2 cm in diameter were found on the mesentery side of the terminal ileum. The enteric duplications were compressing the adjacent ileal lumen. Case 3: A 2,896 g full-term female neonate was referred to us on Day 22. Emergency laparotomy was performed and an enteric duplication measuring 2 cm in diameter was found on the mesentery side of the terminal ileum. The enteric duplication was compressing the adjacent ileal lumen. In all three cases, we performed emergency resection of the enteric duplications with the adjacent intestine owing to intestinal obstruction. We diagnosed the enteric duplications by ultrasonography and computed tomography. Although it is feasible to diagnose this entity preoperatively, it is important to recognize the features of intestinal obstruction induced by enteric duplication.
