Chronic Constipation Leading to Sigmoid Colon Volvulus in an Adolescent

60 Constipation is very common in children1,2. The estimated prevalence of functional constipation in children is 4% to 36%1,2. The complaint of constipation accounts for 3% of children visits to primary physicians and 25% of visits to pediatric gastroenterologist1,2. In spite of its prevalence, it rarely causes serious complications in children, such as sigmoid colon volvulus3. The volvulus of the sigmoid colon is believed to be caused by a twist of the mesentery of the redundant colon3. An abdominal radiograph is helpful in diagnosing the presence of sigmoid volvulus. There are a few specific radiographic signs for sigmoid volvulus, including the dilated ahaustral loops. Rectal tube reduction is very successful in reducing sigmoid volvulus; however, ultimately, most patients require sigmoidectomy4,5.
