Colon capsule endoscopy and its effectiveness in the diagnosis and management of colorectal neoplastic lesions

ABSTRACT

Introduction: Colorectal cancer (CRC) represents a major cause of morbidity and mortality in Western countries. Though colonoscopy is the benchmark for CRC diagnosis and management, other alternatives have been proposed. Colon capsule endoscopy (CCE) was first introduced in 2006 as a non-invasive painless technology that utilizes an ingestible, wireless, and disposable capsule to explore the colon, without sedation or air insufflation.

Areas covered: To date, the European Society of Gastrointestinal Endoscopy (ESGE) guidelines consider CCE as an option for average-risk colorectal cancer screening patients and in patients with contraindications or unwilling to undergo colonoscopy and/or with an incomplete colonoscopy. Furthermore, Japan’s Pharmaceuticals and Medical Devices Agency (JPMDA) and Food and Drug Administration (FDA) approved the use of CCE in patients unwilling or unable to undergo colonoscopy.

Expert commentary: CCE accuracy is nearly comparable to conventional colonoscopy for CRC and significant polyps. Moreover, in the setting of incomplete colonoscopy, CCE was demonstrated to have a higher diagnostic yield for significant polyps and to be better tolerated than CTC. However, the use of CCE is still limited. The lesson coming out is that we should explore new populations that are suitable for colon capsules and for which the colon capsule can be an advantage.
