The umbilical cord remnant distal to the umbilical clamp appeared bluish and was necrotic and swollen, with a size of ~1.5 x 1.5 cm (Figure 1A). Intraoperatively, a loop of small bowel (ileum) that was herniated through the umbilicus was pinched off by the applied umbilical clamp and was necrotic (Figure 1B).
