Capsule endoscopy of the esophagus?

Background: The development of wireless capsule endoscopy (CE) allows the non invasive imaging of the small intestine. It is commonly believed, that other organs are not suitable for CE. Aim: To evaluate the clinical efficacy of CE in the distal esophagus. Patients and Methods: Wireless capsule endoscope measuring 11×27mm was used. The data of 22 patients were evaluated, who were mostly examined for suspected small intestinal bleeding. Results: In the 22 patients the median CE exposure time in the esophagus was 3s (range 1–8s, median of 5 pictures, range 1–16). At least one image of the Z line was obtained in 50…
