title: Mesourachus and colon obstruction.
abstract: The mesourachus is an uncommon anomaly in which the urachal remnant is connected with the anterior abdominal wall by a well-defined mesentery. Likewise, large-bowel obstruction secondary to adhesions and/or congenital bands is very rare in both adults and children. In the following case report of an 8-year-old boy with trisomy 13 syndrome and known intestinal malrotation, a segment of the mesourachus was bound by adhesions to the small-bowel mesentery. This arrangement resulted in severe obstruction of the descending colon, simulating a volvulus.
