Overview
The pathogenesis of infantile hypertrophic pyloric stenosis is not completely understood. However, infantile hypertrophic pyloric stenosis may result from abnormal innervation of the pyloric smooth muscle.
Pathophysiology
The pathogenesis of infantile hypertrophic pyloric stenosis is not completely understood.
- However, infantile hypertrophic pyloric stenosis (IHPS) may result from abnormal innervation of the pyloric smooth muscle.
- Evidence of increased collagen production and abnormal amounts of extracellular matrix proteins has also been seen in patients with hypertrophic pyloric muscle.[1]
- The pathophysiology for adult-onset hypertrophic pyloric stenosis (HPS) is not comprehensively understood.
Genetics
In relatives of probands of infantile hypertrophic pyloric stenosis patients and monozygotic cotwins the recurrence pattern did not depict a single major inheritance.[2]
Associated Conditions of Infantile Hypertrophic Pyloric Stenosis
Various conditions associated with infantile pyloric stenosis include:[3]
- Neuromuscular disorders
- Connective tissue disorders
- Metabolic disorders
- Intracellular signalling pathway disturbances
- Intercellular communication disturbances
- Ciliopathies
- DNA-repair abnormalities
- Transcription regulation disorders
- MAPK-pathway abnormalities
- Lymphatic abnormalities
- Environmental factors
