Ultrasound Diagnosis of Hypertrophic Pyloric Stenosis: Criteria, Technique, and Errors
Limitation of Source Base
This article must rely exclusively on the provided source fragments. However, among them, there are no materials on hypertrophic pyloric stenosis. Not a single fragment contains:
— threshold values for pyloric muscle thickness (criterion stated in the topic >3 mm) [clarify];
— threshold values for pyloric channel length (stated >15–16 mm) [clarify];
— description of the technique for visualization and locating the pylorus [clarify];
— list of diagnostic errors and artifacts [clarify].
What the Available Fragments Contain
The available fragments pertain to other areas of ultrasound diagnostics: POCUS in primary care (Andersen et al., 2026), scrotum (AIUM, 2025; EFSUMB, 2026), abdominal aorta (ACR–AIUM–SRU, 2025), liver elastography (WFUMB, 2024), female pelvic organs, thyroid gland, musculoskeletal system, neonatal neurosonography. Separate pediatric references in the “Textbook of Diagnostic Sonography” concern spleen sizes, abdominal masses, and classification of urinary tract dilation, but not pyloric stenosis.
Recommendation
For a correct and safe (YMYL) publication on ultrasound diagnosis of pyloric stenosis, it is necessary to provide specialized source fragments containing validated numerical criteria and technique descriptions. Until such data is obtained, numerical thresholds and methodological statements should not be presented. [clarify]
Frequently asked questions
What threshold values for muscle thickness are indicated in the source?
These values are absent in the provided fragments. [clarify]
Is there a criterion for pyloric channel length in the fragments?
No, data on channel length (>15–16 mm) is not present in the fragments. [clarify]
Is the technique for locating the pylorus described?
The technique for visualizing the pylorus is not presented in the available fragments. [clarify]
Is it possible to write an article on this topic based on the existing sources?
No. The fragments do not pertain to pyloric stenosis; specialized sources are required. [clarify]
