Definition / general
  • GI duplications are uncommon congenital abnormalities, 80% recognised before age 2; colorectal duplications occur in 7% of cases
  • Rare in adults, may present with rectal bleeding (J Clin Pathol 2010;63:1080, World J Gastroenterol 2005;11:5072)
  • Partial or complete doubling of a variable length of bowel
  • Saccular to long, cystic structures
  • Often present in mesentery of normal bowel without communication with lumen
  • Associated with complex GU abnormalities
Clinical features
  • Cystic (>80%) or tubular; often asymptomatic and undiagnosed
  • Symptomatic colonic duplication is rare in adults; present with abdominal pain and intestinal obstruction; also acute abdomen or acute bleeding, necessitating emergency surgery (BMC Surg 2010;10:19)
