9,419 medical device reports received by FDA name the brand "Colonovideoscope" (colonovideoscope); the manufacturer given most often on reports is Aizu Olympus; received from March 2017 to August 2026. Brand names are as the reporter or manufacturer wrote them, so one product can appear under several spellings.
5,712 reports arrived in the 12 months to August 2026, up 225% from 1,755 in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are malfunction (99.3%) and injury (0.7%); across all colonoscope and accessories, flexible/rigid reports (product code FDF) death is recorded in 0.1% and malfunction in 98.1%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are failure to clean adequately (42.3%), communication or transmission problem (14.5%) and device reprocessing problem (11.8%). The patient problems coded most often are abdominal pain, nausea and ascites. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
