Minimally invasive approach to non-communicating pyloric duplication

Pyloric duplication is a rare subset of alimentary tract duplications that can present in a manner almost identical to hypertrophic pyloric stenosis. Diagnosis can typically be made with an upper gastrointestinal series and ultrasound, though axial imaging is occasionally required. Because most of these malformations do not communicate with the lumen, they can be effectively managed with partial excision and ablation of the common wall mucosa. Here we present an 11-day-old female with pyloric duplication that was successfully managed laparoscopically.
