Acquired diverticula of the small bowel are mainly located in the duodenum, followed by the jejunum. They are typically asymptomatic, but may occasionally cause massive bleeding, diverticulitis, and even perforation. Meckel’s diverticula are a remnant of the omphalomesenteric duct located in the ileum. They can cause overt bleeding, typically in children, but also in adults. Sensitivity of Meckel’s scintigraphy in adults seems limited. SBCE is a useful diagnostic tool, although the sensitivity of the more invasive retrograde enteroscopy for Meckels’s diverticulum is higher. Typical findings at SBCE are a double lumen with a septum, visible diverticular entrance, and linear or circular ulcers. Occasionally ectopic mucosa or active bleeding can be visualized.

摘要

Acquired diverticula of the small bowel are mainly located in the duodenum, followed by the jejunum. They are typically asymptomatic, but may occasionally cause massive bleeding, diverticulitis, and even perforation. Meckel’s diverticula are a remnant of the omphalomesenteric duct located in the ileum. They can cause overt bleeding, typically in children, but also in adults. Sensitivity of Meckel’s scintigraphy in adults seems limited. SBCE is a useful diagnostic tool, although the sensitivity of the more invasive retrograde enteroscopy for Meckels’s diverticulum is higher. Typical findings at SBCE are a double lumen with a septum, visible diverticular entrance, and linear or circular ulcers. Occasionally ectopic mucosa or active bleeding can be visualized.
