Gastroscopes are used in upper endoscopy (EGD) procedures to examine the esophagus, stomach, and duodenum. If you developed a serious infection after an upper endoscopy using an Olympus gastroscope, you may have a legal claim.
A gastroscope (also called an upper endoscope or esophagogastroduodenoscope) is a flexible endoscope used during upper endoscopy or EGD (esophagogastroduodenoscopy). This procedure allows physicians to visualize the esophagus, stomach, and first part of the small intestine (duodenum) for diagnosis and treatment of conditions including ulcers, GERD, Barrett's esophagus, and upper GI bleeding.
Upper endoscopy is one of the most commonly performed endoscopic procedures, with millions conducted each year in the United States. Gastroscopes have internal channels for suction, air/water delivery, and instrument passage that must be meticulously reprocessed between patients. Incomplete cleaning can leave behind blood, tissue, and bacterial biofilms.
Olympus manufactures several widely used gastroscope models, including the GIF-HQ190, GIF-H190, and GIF-XP190N. These devices are found in hospitals, outpatient endoscopy centers, and ambulatory surgery centers nationwide. The reprocessing challenges that affect other Olympus endoscopes also apply to gastroscopes.
Olympus gastroscopes and the endoscope lawsuit
While the Olympus endoscope lawsuit has focused primarily on duodenoscopes, gastroscopes share many of the same reprocessing vulnerabilities. Internal channels, instrument ports, and distal tip components all present potential contamination risks when reprocessing is incomplete.
Gastroscope contamination lawsuits allege that Olympus failed to adequately design devices for effective cleaning, provided insufficient reprocessing guidance, and did not promptly address reports of gastroscope-related infections. Because upper endoscopy is considered a routine, low-risk procedure, patients are often unprepared for the possibility of device-transmitted infections.
Studies have documented bacterial contamination on reprocessed gastroscopes, including organisms associated with serious infections. The volume of upper endoscopy procedures performed daily means that even a small contamination rate can affect a large number of patients.
Injuries from contaminated gastroscopes
Patients who undergo upper endoscopy with a contaminated gastroscope may suffer:
Bacterial infections of the upper GI tract, including H. pylori cross-contamination
Esophageal infections following biopsy or dilation procedures
Bacteremia from organisms introduced through the gastroscope during the procedure
Sepsis requiring hospitalization, IV antibiotics, and intensive care
Perforation injuries to the esophagus, stomach, or duodenum
Hemorrhage from device malfunction during therapeutic procedures
Hepatitis or other pathogen transmission in cases of severe reprocessing failure
Legal theories in gastroscope cases
Gastroscope lawsuits may pursue design defect claims (internal channels resistant to thorough cleaning), failure to warn (inadequate patient and provider information about contamination risks), and breach of implied warranty (the device does not perform safely for its intended use).
The routine nature of upper endoscopy strengthens patient claims because there is a reasonable expectation that a screening or diagnostic procedure will not introduce life-threatening infections. Attorneys evaluate gastroscope claims based on procedure timing, infection type, device model, and available evidence of reprocessing failures.
Evidence for gastroscope claims
Upper endoscopy (EGD) procedure records identifying the Olympus gastroscope model
Post-procedure infection diagnosis with cultures and sensitivity results
Hospitalization records within 90 days of the upper endoscopy
Follow-up care records documenting treatment of the infection
Hospital or facility notifications about endoscope-related contamination
