[Anatomo-clinical and echocardiographic correlations in hypertrophic pyloric stenosis. Apropos of 32 cases].

The authors present diagnosis particularities in 32 cases of hypertrophic pyloric stenosis, from 1980 to 1984, whom 21 cases since 1982 (25 boys, 7 girls). The diagnosis of HPS was confirmed by sonographic and roentgen explorations, isolated or associated: ultrasound alone 3 cases, ultrasound and roentgen combined 29 cases either roentgen first (22) or ultrasound first (7). Fiability was made for 22 cases; two times, error came from false interpretation; eight times were "false negative" results, corrected by roentgenogram, and corresponding with a voluminous pylorus (3) or little, sclerosis pyloric lesions (5). Amelioration of results give, from the last year, right diagnosis in 85 per cent, about 13 cases.
