Anomalous congenital band: a rare cause of intestinal obstruction and failure to thrive.

Intestinal obstruction caused by an anomalous congenital band is very rare in adults and children. A 7-year-old boy was admitted with acute intestinal obstruction. His parents mentioned that the child always had mild abdominal distention and failure to thrive from his infancy. On his medical history, there were not any attacks of abdominal pain, fever and hospitalization. Laparotomy showed an ileal loop compressed by an anomalous band, which extended from the ileum to the sigmoid mesentery resembling a mesenteric remnant. The band was resected. Histologically, it was composed of loose connective tissue containing mature vessels.
