Abstract
Recently, most infants with congenital hypertrophic pyloric stenosis (CHPS) are operated on, but some receive conservative therapy followed by operation. To elucidate the appropriate therapy for CHPS, we analysed 62 infants with CHPS who were operated on in our hospital from 1975 to 1988.
As for conditions on admission, the longer the periods from the onset to admission were, the less their body weight were gained. Most infants who came late after the onset had been treated conservatively.
Imblalance in the electolites and fluids in these infants were corrected preoperatively according to their acid-base balance, serum electrolyte values, and other clinical data. Only 8 infants with hypovolemic shock or poor general conditions, who were admitted late in the course, required plasma infusion. Base excess, one of our major guides of preoperative management, was corrected to the normal level within 24 hours after initiation of therapy in 35 infants who came to our hospital without previous therapy.
Based upon these data, we have confirmed that the infants who are diagnosed as CHPS have to undergo the operation immediately after correcting the electrolyte imbalance and dehydration.
