CLINICAL RISK-FACTORS OF HIRSCHSPRUNG-ASSOCIATED ENTEROCOLITIS .2. POSTOPERATIVE ENTEROCOLITIS

Among 302 Hirschsprung patients diagnosed between 1976 and 1993, 213 p atients who had undergone definitive operations for Hirschsprung's dis ease (HD) were reviewed for the occurrence of postoperative Hirschspru ng-associated enterocolitis (HAEC). The role of 42 parameters were ana lyzed. We detected 34 patients (14.0%) with postoperative HAEC with no mortality. In nine patients (26.5%) HAEC persisted postoperatively bu t no effect of preoperative HAEC on postoperative HAEC was detected. T he length of the aganglionic segment did not have any effect on HAEC. Down's syndrome was not present in any of our patients with HAEC. Ente rocolitis appeared after Swenson, Duhamel and Boley operations In 23, 10 and one patient, respectively. The incidence of HAEC was inversely proportional to age and weight at the time of definitive operation. Th e presence of colostomy before or during definitive operation had no e ffect on postoperative HAEC. Complications of definitive operations, i ncluding strictum, did not have any effect on HAEC.
