Isolated Segmental Sigmoid Structure after Necrotizing Enterocolitis: A Rare Localization of the Stricture Out of the Late Complication

In one-third of newborns with necrotizing enterocolitis (NEC) can take place intestinal stricture as a late complication. Contrast enema studies are routinely carried out prior to stoma closure following NEC. The locations of strictures are often in ascending colon/hepatic flexure, transverse colon/splenic flexure and descending colon together with sigmoid or multiple colonic areas. The stricture is less common in small bowel segments than those of the large bowels. This report describes a isolated segmental sigmoid colon stricture after NEC of which was 5 mm in diameter and 5 cm in length of a male infant who was born via cesarean section at 38 weeks of gestation with weighing 2140 grams. We firstly found and described this complication as a solitary stricture in the sigmoid colon for the first time. We believe that due to early diagnosis and treatment, the stricture did not compose of in the previous segments and strictly limited to this region only. However, it is a dilemma whether more or fewer practitioners cannot escape from this fate or not.
