Sigmoid adhesion caused by a congenital mesocolic band

Congenital mesocolic band is an uncommon aberration in the development of t he mesentery. Large-bowel obstruction secondary to adhesion and/or congenit al band is very rare in children. A 6-month-old male infant who had no hist ory of previous surgery was admitted with unremitting crying. A barium enem a showed extraintestinal compression of the sigmoid colon. Laparotomy revea led an adhesive mesocolic band compressing the proximal part of the sigmoid colon. The band was lysed. The patient has remained asymptomatic since the procedure.
