Abstract
Up until the past 10 years, the diagnostic work-up for small-bowel diseases, employing modalities such as contrast studies and computed tomography, was poor and mostly unyielding. Push enteroscopy and intraoperative enteroscopy were performed in a few experienced institutions. However, it is not possible to reach all portions of the jejunum and the ileum by the push enteroscope, while intraoperative enteroscopy demands a surgical route. The introduction of capsule endoscopy has been a long-awaited advance in the diagnosis of small-bowel lesions. Wireless capsule endoscopy has overcome obstacles, but still has some weaknesses, such as the inability to biopsy and treat the detected lesions. Capsule endoscopy also has some limitations in patients with surgical strictures and in those with altered gastrointestinal anatomy, including Roux-en-Y reconstruction [1] [2] [3].
