Sigmoidal volvulus in childhood: report of two cases.

Volvulus of the sigmoid colon is a very uncommon cause of acute obstruction in children. Although common in adults in India, it was found to account for only 0.8 per cent of all acute obstructions in infants and children in this institution. It causes a proximal torsional obstruction of the colon with an acute onset of symptoms. The onset of volvulus is characterized by colicky pain over the left lower quadrant, vomiting, tenderness, and rigidity in te left lower quadrant. A scout film of the abdomen may be inconclusive, but a barium-enema examination is diagnostic. The number of cases reported is too small to allow conclusions about the best treatment for children who have sigmoidal volvulus.
