Abstract

Twenty-seven patients of hypertrophic pyloric stenosis operated on at our hospital between 1977 and 1991 were reviewed. The patients consisted of 22 boys and 5 girls, with males accounting for 81%. Seventeen of the 27 patients were the first children of their mothers. Vomiting was first noted between 10 and 58 days after birth with a mean of 26.5 days, and neonatal onset was observed in 67% of all patients. The body weight decreased after the onset in 17 patients, including 1 in which it decreased below the birth weight. Hypochloremia was the most frequent preoperative electrolyte imbalance, being observed in 41% of all patients. Alkalosis was noted in 17 of the 22 patients in which arterial blood gas analysis could be performed. The olive was palpated preoperatively in 24 (89%) of the 27 patients. The body weight increased in all patients after operation, and the mean daily increase was 26.7 g. The mean period of hospitalization after operation was relatively short at 8.3 days. Postoperative vomiting was observed in 16 patients (59%), with its mean duration being 26 days. All patients showed normal growth after operation, and no postoperative complications were noted.
