Olympus Colonoscopy Lawsuit Over C. Diff Infection Set for Status Hearing in September 2026

A federal lawsuit has been filed against Olympus Corporation over allegedly defective and contaminated colonoscopes that transmit bacterial infections to patients during medical procedures. The plaintiff, Denise Hopkins from Chicago, filed the case in the U.S. District Court for the Northern District of Illinois on July 9, 2026, and the matter has been assigned to U.S. District Judge Sunil R. Harjani.

According to the complaint, Hopkins underwent a colonoscopy in August 2024 using an Olympus CF-HQ190L colonoscope that was not properly sterilized. Following the procedure, she developed a Clostridioides difficile (C. diff) infection, which is a serious bacterial infection capable of causing severe diarrhea, colon inflammation, and long-term health complications. Hopkins alleges the infection resulted directly from contamination remaining inside the reusable medical device.

Colonoscopes are specialized endoscopic instruments containing cameras, lights, narrow channels, and moving parts used in various minimally invasive procedures. The case highlights concerns that bacteria can persist within reusable Olympus colonoscopes despite cleaning protocols, potentially exposing multiple patients to serious infections. An initial status conference has been scheduled for September 29, 2026, to discuss the litigation and procedural next steps.
