Do all flexible endoscopes contain internal channels?

Flexible endoscopes are designed to allow for visibility and access within various anatomical structures. However, not all flexible endoscopes contain internal channels, which are specifically used for the passage of instruments or suctioning during procedures.

The presence of internal channels depends on the purpose and design of the endoscope. Some flexible endoscopes are built solely for visualization, lacking channels entirely, while others, such as those used for therapeutic interventions, include one or more internal channels to facilitate procedures like biopsies or the removal of tissue. Because of this diversity in design, stating that all flexible endoscopes have internal channels is inaccurate.

It's important to recognize that the statement must account for the variety of endoscope types used in medical practice, leading to the conclusion that not every flexible endoscope is equipped with these internal passages. This understanding is crucial for proper device selection and for ensuring appropriate use in clinical settings.
