A Case of Duodenoduodenal Intussusception Secondary to Duodenal Polyp

Abstract

Adult intestinal intussusception accounts for 1 to 5 percent of mechanical bowel obstructions and is relatively rare. Its presentation, aetiology and treatment varies greatly from childhood intussesception. Duodenoduodenal intussusception (DDI) is unusual due to fixed position of the duodenum within the retroperitoneum with only a few cases of adult DDI reported in literature. In adults, a pathologic lead point within the bowel typically leads to intussusception, and this may be malignant in up to 77 percent of cases. DDI is a challenging condition due to its rarity and nonspecific presentation. Here, we present a case of DDI secondary to a duodenal polyp.
