title: Laparoscopic pull-through procedures using the harmonic scalpel in infants and children with Hirschsprung's disease.
abstract: Hirschsprung's disease in infants has routinely been treated by a three- or four-stage process requiring a rectal biopsy, diverting colostomy, pull-through procedure, and then colostomy takedown. This algorithm requires multiple hospitalizations and surgeries over several months. The authors have adopted a laparoscopic approach that allows the surgery to be performed in one stage with a marked decrease in morbidity and hospital stay. From March 1995 to May 1996, 15 infants and children, ages 7 days to 8 years and weighing 2.3 kg to 40 kg, underwent laparoscopic pull-through procedures. Eleven underwent primary pull-through, while four underwent a previous diverting colostomy. The laparoscopic portion of the pull-through was performed using three or four ports, size 3.5 mm or 5 mm and an ultrasonic dissector. The final submucosal dissection was performed transrectally starting 1 cm above the pectinate line. The rectal anastomosis was hand sewn, and no patient was left with a diverting colostomy. Operative time averaged 2 hours and 50 minutes. Average time to feeds was 1.3 days and the average days to discharge was 3.4. There was one intraoperative pathology misdiagnosis and one patient with an anastomotic stricture. All patients are excreting stools spontaneously at least daily and there have been no episodes of colitis. This preliminary report shows that the one-stage laparoscopic pull-through is safe and effective.
