Endoscopic Reduction of Sigmoid Volvulus in a 15-Year-Old Male

摘要

Sigmoid volvulus is a well-recognized phenomenon in the elderly but rare in children. The proposed mechanism involves rotation of a redundant sigmoid loop around a narrow, elongated mesentery with subsequent vascular occlusion. The condition can be intermittent or may resolve spontaneously, complicating diagnosis. Early diagnosis is imperative to prevent ischemic complications including necrosis, perforation, and sepsis. Abdominal pain, abdominal distention, and vomiting are the most common presenting symptoms, however abdominal tenderness is uncommon. Colonic dilation is the most frequent finding on abdominal radiograph. Contrast enema reveals a “bird’s beak” configuration of the twisted colon and moreover, is successful in reducing the majority of pediatric cases. If there is no evidence of bowel ischemia or perforation, endoscopic reduction has been proposed as first-line treatment for sigmoid volvulus, especially in children. We report the case of 15-year-old male in which endoscopic reduction of sigmoid volvulus was successful without complication.
