Background:

Infantile hypertrophic pyloric stenosis (IHPS) requires surgical correction.
The standard semi-circumumbilical incision for Ramstedt pyloromyotomy offers suboptimal access in up to 30% of cases.
This can lead to complications such as seromuscular lacerations.

Purpose of the Study:

To evaluate a modified pyloromyotomy technique using a sliding umbilical window for improved surgical access.
To assess the safety and efficacy of this new approach in infants with IHPS.

Main Methods:

A full-circumumbilical incision was used to create a sliding umbilical window.
The window was maneuvered to provide direct access to the hypertrophied pylorus.

Ramstedt pyloromyotomy was performed intracorporeally in 13 consecutive infant cases.

Main Results:

All 13 pyloromyotomies were successfully completed without complications.
Wounds healed primarily with no conspicuous scarring, abscesses, or hernias.
Postoperative recovery was uneventful for all infants.

Conclusions:

The sliding umbilical window technique provides superior access and exposure of the pylorus.
This method facilitates safe, intracorporeal pyloromyotomy with excellent cosmetic outcomes.
The approach is safe and effective for treating infantile hypertrophic pyloric stenosis.
