Laparoscopic-assisted Open Pyloroduodenostomy Repair of Pyloric Atresia in an Infant: A Rare Congenital Anomaly

Purpose: Pyloric atresia is an uncommon congenital anomaly that may present with emesis and dehydration early in infancy. Definitive therapy consists of pyloroplasty or gastroduodenostomy depending on the subtype of atresia involved.

Case presentation: We report the case of a 2-day-old girl infant who presented with nonbilious emesis with feeds. Abdominal ultrasound and upper gastrointestinal series were performed and demonstrated a dilated, air-filled stomach with no distal air or passage of contrast. The patient was successfully treated by laparoscopic-assisted open pyloroduodenostomy of a type 2 pyloric atresia.

Conclusion: Type 2 pyloric atresia is a rare clinical entity that can present with symptoms of gastric outlet obstruction. The patient described was treated by laparoscopic-assisted open pyloroduodenostomy, which has not been previously described for pyloric atresia. This work demonstrates an example of the safety and efficacy of laparoscopic surgery for infants with this anomaly.
