Surgery for neonatal duodenal atresia often includes transection and anastomosis. 1. Transverse resection: refers to transverse resection via the right side over the navel, which is suitable for neonates with proximal duodenal obstruction, with good exposure during the operation, and also facilitates full abdominal examination. 2. Anastomosis: including duodenal side anastomosis and duodenojejunal anastomosis. Among them, duodenal side anastomosis is suitable for neonates with both ends of duodenal atresia close to each other; duodenojejunal anastomosis is mainly suitable for post-colonic anastomosis, which promotes the smooth drainage of food. Neonatal duodenal atresia, the impact on the body is relatively large, should be timely to the hospital, active treatment.
