Resumen
PRIETO, Robin Germán et al. Duplications of digestive tract. rev. colomb. cir. [online]. 2018, vol.33, n.2, pp.198-205. ISSN 2011-7582. https://doi.org/10.30944/20117582.62.
Alimentary tract duplications are rare congenital lesions that can occur anywhere in the gastrointestinal tract. Three hypotheses about their etiology had been proposed, The luminal recanalization theory, the intrauterine vascular accident theory, and the abortive twinning theory.
According to some series, three quarters of gastrointestinal duplications are cystic with no communication to the adjacent alimentary tract, while the remaining are tubular and may communicate with the intestinal lumen.
They have three essential characteristics: they are attached to any segment of the gastrointestinal tract and with the same blood supply, having a muscular layer and possessing an epithelial lining that corresponds generally to the mucosa of the same path.
The most common symptoms are nonspecific abdominal pain, nausea, vomiting, gastrointestinal hemorrhage, invagination, obstruction, jaundice and pancreatitis. The diagnosis is based mainly on imaging studies, ranging from simple radiography to nuclear resonance, with prenatal ultrasound being of great importance. Surgical treatment is the main therapeutic option, being increasingly used the laparoscopic route.
