Current trends in the diagnosis and treatment of pyloric stenosis.

Aim: We hypothesized that recent trends towards earlier diagnosis of hypertrophic pyloric stenosis continued throughout the early part of the 21st century.

Methods: We reviewed the medical records of patients with HPS at a single institution during two periods: 1/03-12/05 and 4/09-7/13.

Results: A total of 433 patients with hypertrophic pyloric stenosis who underwent pyloromyotomy were included (modern cohort = 259; historic = 174).
