    Notes: Abstract Enterocolitis remains a major cause of morbidity and mortality in patients with Hirschsprung's disease (HD). Forty-one (30%) of 135 patients treated for HD from 1975 to 1992 developed enterocolitis; enterocolitis occured preoperatively in 25. It was a presenting feature in 17 infants, including 11 neonates. The proportion of patients presenting with enterocolitis in the neonatal period increased with advancing age, 6 (11%) out of 56 presenting within the 1st week and 5 (24%) out of 21 after 1 week. Episodes of enterocolitis continued in 7 of these 25 patients after a pull-through procedure. Sixteen patients had a first episode of enterocolitis after surgery: 3 after a colostomy, and 13 after a pull-through procedure. The incidence of enterocolitis was 28% in patients with rectosigmoid involvement and 38% in patients with long-segment or total colonic aganglionosis (P= 0.1). Enterocolitis occured in 8 (47%) of 17 patients with trisomy 21 as compared to 33 of 118 (28%) other patients (P= 0.1). Four of the 41 patients died as a result of enterocolitis, 3 in the neonatal period after a colostomy performed at a mean age of 22 days, although the symptoms suggestive of HD were present since birth. Prompt diagnosis and expeditious management are necessary in patients with HD.

    Notes: Abstract Intercellular adhesion molecule-1 (ICAM-1) is a glycoprotein that is necessary for the transendothelial migration of leucocytes. This study was undertaken to elucidate the role of ICAM-1 in the pathophysiology of Hirschsprung's disease (HD)-related enterocolitis. Ganglionic and aganglionic portions of bowel from 18 patients with HD who did not have clinical or histological evidence of enterocolitis and 5 patients with HD who developed enterocolitis before or after a pull-through operation were stained using monoclonal antibody against ICAM-1. The bowel specimens obtained from 2 children with imperforate anus at the time of colostomy closure and 3 children at the time of bladder augmentation were similarly stained to act as controls. The ganglionic portion of bowel from patients with HD without enterocolitis and controls showed either no ICAM-I staining or occasional staining of the endothelial lining of submucosal vessels with no staining of the glandular crypt epithelium. In contrast, both ganglionic and aganglionic bowel from patients with enterocolitis complicating HD demonstrated strong ICAM-1 staining in the endothelium of submucosal vessels. Strong expression of ICAM-1 in the glandular crypt epithelium was seen in only 2 patients who had developed enterocolitis before pull-through operations. This study illustrates the importance of endothelial cell activation in the pathogenesis of HD-related enterocolitis.
