    Area of Science:

    • Pediatric Surgery
    • Gastrointestinal Surgery

    Background:

    • The Heineke-Mikulicz pyloroplasty, while common, can be inadequate in children due to size limitations and funnel distortion.
    • The Y-V advancement principle, reintroduced in 1958, offers potential advantages in pyloric enlargement but has seen limited adoption.

    Purpose of the Study:

    • To evaluate a modified Y-V pyloroplasty technique utilizing a U-shaped pedicle for pyloric enlargement.
    • To assess the safety, efficacy, and long-term outcomes of this modified pyloroplasty in pediatric patients.

    Main Methods:

    • A modified Y-V pyloroplasty was performed using a U-shaped pedicle from the gastric antrum advanced into the duodenum.
    • The procedure was applied to 33 patients (3 weeks to 17 years) for various conditions including delayed gastric emptying, ulcers, and esophageal issues.
    • Patients were followed for 6 months to 10 years.

    Main Results:

    • The modified pyloroplasty was successfully used in 33 pediatric patients.
    • Complications were minimal, and gastric drainage was highly satisfactory.
    • Long-term follow-up showed no adverse effects from antral mucosa in the duodenum.

    Conclusions:

    • The modified Y-V pyloroplasty with a U-shaped pedicle is a simple, safe, and effective technique for pyloric enlargement in children.
    • This method provides maximal channel size with minimal operating time and satisfactory long-term outcomes.
