What is the treatment for duodenal atresia in infants?

The appropriate treatment for duodenal atresia in infants involves creating an anastomosis to allow for the passage of contents through the duodenum. Duodenoduodenostomy is the procedure that connects the proximal and distal segments of the duodenum, thereby bypassing the atretic segment. This surgical intervention addresses the obstruction caused by duodenal atresia and enables the infant to begin feeding.

The other options presented are not relevant to the treatment of duodenal atresia. Esophagectomy is a surgical procedure to remove part or all of the esophagus, which is unrelated to the treatment of duodenal atresia. Gastric bypass is a weight-loss surgery primarily intended for adults with obesity and does not address the congenital obstruction. Ileal resection involves the removal of a segment of the ileum, which is pertinent to conditions affecting the lower part of the small intestine, not to duodenal atresia.

In summary, duodenoduodenostomy is the most appropriate surgical option for infants diagnosed with duodenal atresia, facilitating a functional gastrointestinal pathway.
