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)
Case reports

- 10 year old girl with duplication cyst of ascending colon presenting as an ileal volvulus (Afr J Paediatr Surg 2012;9:237)
- 12 year old girl with Y shaped colonic duplication (Chang Gung Med J 2011;34:43)
- 25 year old man with total colorectal and terminal ileal duplication presenting as intussusception and intestinal obstruction (World J Gastroenterol 2012;18:6338)
- 28 year old man with combined duplication of colon and appendix (World J Gastroenterol 2008;14:641)
- 29 year old woman with large tubular colonic duplication (J Korean Surg Soc 2012;82:190)
- 43 year old woman with colonic duplication mimicking a tumor of pancreas (World J Gastroenterol 2008;14:966)
- Mimicking fistulizing Crohn's colitis (Inflamm Bowel Dis 2011;17:E103)
- Two unusual cases of congenital pouch colon and segmental dilatation of colon (J Indian Assoc Pediatr Surg 2011;16:61)
Treatment
- May not require treatment (Yonsei Med J 2005;46:189)
