Abstract
Objective To retrospectively analyze the differential diagnosis and treatment strategy of neonatal intestinal perforation caused by neonatal necrotizing enterocolitis (NEC) and Hirschsprung′s disease (HD). Methods The clinical data of 42 cases with NEC and 22 cases with HD combined with intestinal perforation from Ja-nuary 2012 to January 2017 admitted at Fujian Provincial Maternity and Children′s Hospital were collected, the proportion of premature infants, and the proportion of low birth weight infants, age of onset, preoperative clinical symptoms and surgical treatment was compared between the two groups. Results The proportion of premature infants[95.23%(40/42 cases) vs.27.27%(6/22 cases)], the proportion of low birth weight infant[90.48%(38/42 cases) vs.45.45%(10/22 cases)]and the age of onset [(14.48± 10.51) d vs.(3.18±3.43) d]were statistically different between the NEC group and the HD group, and the differences were statistically significant(all P<0.05). There were significant differences in the presence of normal defecation before the operation[71.4% (30/42 cases)vs.27.3%(6/22 cases)], and in the the defecation characteristics at the onset[95.2% (40/42 cases)vs.9.1%(2/22 cases)]between the NEC group and HD group(all P<0.05). Among 42 cases of NEC patients, 8 cases underwent intestinal anastomosis, and 34 cases underwent enterostomy because of the high risk of anastomosis.All of 22 patients with HD underwent double-lumen enterostomy. Conclusions The general conditions, preoperative manifestations and intraoperative fin-dings of the children should be comprehensively analyzed for identification.Enterostomy is recommended for NEC intestinal perforation, but if the risk of anastomosis is high, then fistula should be performed.Double-lumen fistula should be recommended for HD intestinal perforation, and enterostomy should be recommended if the two cannot be clearly distinguished.
