Hypertrophic pyloric stenosis (HPS) can occur in newborns, even before 3 weeks of age. This condition, a common cause of infant vomiting, should be considered in the diagnosis of newborns presenting with non-bilious vomiting.
Area of Science:
- Pediatric Surgery
- Neonatal Medicine
- Medical Imaging
Background:
- Hypertrophic pyloric stenosis (HPS) is the most frequent surgical cause of vomiting in infants.
- HPS typically manifests between 3 to 5 weeks of life.
- Early presentation, even within the first week of life, has been documented.
Observation:
- This report details a case of HPS identified via prenatal ultrasound.
- The infant presented with symptoms consistent with HPS postnatally.
Findings:
- Prenatal diagnosis of HPS is possible.
- HPS can present earlier than typically observed.
Implications:
- Prenatal ultrasound can aid in the early detection of HPS.
- Considering HPS in the differential diagnosis for neonatal non-bilious vomiting is crucial for timely intervention.
- Early identification may lead to improved infant outcomes.

Surgical Interventions for Peptic Ulcer Disease
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
