Pediatric Sigmoid Volvulus: A Report on Two Cases.

Sigmoid volvulus is a rare cause of intestinal obstruction in the pediatric age group. Rotation of the redundant sigmoid colon about its narrow mesenteric base results in vascular compromise and large bowel obstruction. Predisposing factors for sigmoid volvulus are Hirschsprung's disease, congenital anomalous fixation of the colon, and chronic constipation. Here, we report two cases of sigmoid volvulus in children with redundant sigmoid colon in the South Indian subcontinent. If it is not diagnosed in time, it may lead to serious complications such as gangrene, perforation, septic shock, and eventually death. Thus, the condition warrants prompt evaluation and treatment.
