[Hypertrophic pyloric stenosis in infants: laparoscopic pyloromyotomy].
OBJECTIVE
To evaluate the results of laparoscopic pyloromyotomy in infants with hypertrophic pyloric stenosis (HPS).


METHODS
Retrospective.


METHODS
Data from medical records were collected on all children who underwent laparoscopic extramucosal pyloromyotomy for hypertrophic pyloric stenosis in the period from 1 October 1993 to 31 March 2001 in the Wilhelmina Children's Hospital of the Utrecht University Medical Centre, the Netherlands.


RESULTS
A total of 133 children were operated: 108 boys (81%) and 25 girls (19%). The mean age on the day of operation was 35.3 days (SD: 15.4). Of these children, 17 (13%) were ex-prematures and 8 (6%) were ex-dysmatures, and 40 (30%) had a positive family history for HPS. The mean operating time was 29 min (SD: 10); per surgeon, the first 5 operations required over 30 minutes on average and the following operations lasted an average of 26 minutes. Postoperatively, 84 patients (63%) no longer vomited. Four children required a second operation. The mean period from operation to discharge was 61.6 hours (SD: 46.0). Complications included: perforations of the mucosa (n = 4; 3%), wound infections (n = 4; 3%) and small incisional hernias (n = 5; 4%).


CONCLUSIONS
Laparoscopic pyloromyotomy is an efficient and safe operative technique for the treatment of infants with HPS.
