The maintenance and testing of flexible endoscopes have a direct impact on how reliably the devices perform in clinical work. Leak testing is one of the most important steps in this process, even though in practice it often receives too little attention in many units.
Even a small undetected leak can allow moisture to enter the endoscope’s internal structures, increasing the need for repairs, shortening the device’s service life, and causing operational downtime. Industry guidelines consider leak testing an essential part of the proper maintenance of flexible endoscopes. Leak testing should be carried out after every use and before manual cleaning, in accordance with the manufacturer’s instructions.
Why is leak testing so important?
Flexible endoscopes are complex and valuable devices. Their structures contain delicate channels, joints, and surfaces where moisture can cause internal damage at an early stage. The problem is not always visible from the outside right away, so a visual inspection alone is not enough. Leak testing should always be performed before cleaning, when the endoscope would otherwise be exposed to water. This makes it possible to detect a leak in time and prevent moisture from causing further damage inside the device.
Regular leak testing is also an important part of controlling repair costs. A leak detected early is often significantly less expensive to address than more extensive internal moisture damage. In addition, unnecessary downtime places a burden on the unit’s operations and can make daily planning more difficult. Testing regularly and early helps identify leaks at an early stage, reduces the risk of more extensive damage, and supports the safe use of the device. It also helps prevent situations in which a damaged endoscope progresses too far in the handling process before the problem is noticed.
Leak testing should always be performed before cleaning
Leak testing is not an optional extra step that can be done only if time happens to allow. It is part of the correct procedure according to both manufacturers’ and authorities’ guidelines. According to CDC recommendations, leak testing should be performed after every use and before manual cleaning, following the manufacturer’s instructions.
In many units, leak testing is still performed manually. The process depends on the user remembering to carry out the test at the right point in the workflow, in the right way, and every single time. This is exactly where a practical challenge arises. In everyday work, the step may be skipped because of hurry, varying routines, or simple human forgetfulness. The result can still be costly. A single missed test may be enough for the damage to progress further than necessary.
Repetitive manual work is exposed to variation. Workload, time pressure, and staff turnover are easily reflected in how consistently routines are followed. That is why automation has become an important topic, especially in environments where many devices are handled and processes must function reliably day after day.
Automating leak testing makes everyday work easier and reduces repair costs
The greatest benefit of automation is not speed alone. Even more important is repeatability. Consistent testing helps ensure that leak testing is actually carried out and that its quality does not vary depending on the user’s experience or the pressure of the situation. This supports both patient safety and device management. Early detection of leaks reduces the risk that a damaged endoscope will proceed further into the cleaning and disinfection process.
Leak testing can be automated easily with the LeakControl device. LeakControl is an automated endoscope leak tester designed to detect leaks at an early stage before the device is exposed to water or moves on to the next cleaning steps. This allows possible faults to be identified in time, so repairs are often smaller and costs easier to manage.
LeakControl is connected to the endoscope before it is moved into the water bath. The device pressurizes the endoscope and monitors whether the pressure drops during the test. According to the manufacturer, the test time is usually 60 or 120 seconds depending on the size of the endoscope. If the system detects a leak, it alerts the user and keeps the endoscope pressurized until the device is removed from the water and the test is stopped. The aim is to detect leaks in time before moisture can enter the internal structures of the device and before a leaking endoscope proceeds to the next cleaning stages.
