Abstract
During a 12-year period (1980-1992), 82 cases of infantile hypertrophic pyloric stenosis (IHPS) have been diagnosed at the Chang Gung Memorial Hospital. Patient ages ranged from 17 days to 3 months, with a male to female ratio of 3.1:1. Sonography had been used to diagnose IHPS in this hospital since 1987. Before that time, IHPS preoperative diagnostic methods for 36 cases were as follows: (1) there were 9 cases (25%) with typical vomiting symptom and palpable pyloric mass. (2) Another 10 cases (28%) has palpable pyloric mass, as confirmed by upper GI series. (3) The Other 17 cases (47%) had no palpable pyloric mass and were completely diagnosed by UGI series. After that time, 46 cases were routinely screened with sonography with typical vomiting symptoms. Positive criteria by sonography were that an anterioposterior diameter of pyloric mass greater than 1.5 cm; muscle thickness greater than 0.4 cm; and pyloric length greater than 2.0 cm. There were 42 positive cases (91%); the other 4 cases were negative or suspicious, and thus diagnosed by UGI series. The sensitivity yas 0.91. Sonography is a non-invasive diagnostic tool. It can reduce X-ray exposure and also avoid contrast media complications caused by UGI series. According to experience here with a high and correct diagnostic rate, it is recommended that sonography can be used to screen the patients for IHPS.
