| Abstract |
Purpose
: This study was done to analyze the changes in the clinical conditions and the diagnosis
of hypertrophic pyloric stenosis.
Methods
: We report a retrospective clinical analysis of 39 patients with hypertrophic pyloric
stenosis from Jan. 1992 to Aug. 2001. The age and sex distribution, family and birth history,
clinical symptoms, the ultrasonographic and the operative sizes of pyloric canals were compared.
Results
: The body weight was below the 3 percentile at admission in eight cases(20.5%). “Olive
like mass” in right upper quadrant was palpated during physical examination in 23 cases(59%)
and gastric peristaltic wave observed in six cases(15%). The ultrasonographic measurements
showed that the pyloric muscle thickness to be 4.95±0.99 mm(mean±SD), pyloric diameter
14.42±2.64 mm, and pyloric length 20.17±3.92 mm. Fredet-Ramstedt pyloromyotomy was employed
in all cases. The operative measurements of the pyloric muscle thickness was 5.11±1.01
mm, pyloric diameter 15.01±2.47 mm, and pyloric length 22.32±3.43 mm.
Conclusion
: There was no significant difference between the ultrasonographic and operative
measurements. Currently, the hypertrophic pyloric stenosis patients showed lesser clinical hallmarks
of the disease. The earlier diagnosis using imaging studies before development of significant
metabolic abnormalities is becoming an important factor that change the future outcomes of
hypertrophic pyloric stenosis. |
