Source: Wang, L., et.al. Full-Endoscopic Isolation Zone Technique for the Treatment of Lumbar Disc Herniation. J. Vis. Exp.(2023)This video demonstrates a minimally invasive endoscopic procedure to treat lumbar disc herniation by removing the protruded nucleus pulposus and ruptured annulus fibrosus. The technique decompresses the affected nerve root, alleviates pain, and restores nerve function through targeted tissue resection and radiofrequency modulation.

The topical anesthetic lidocaine was atomized using a high oxygen flow through the working channel of a flexible intubating endoscope to achieve topical airway anesthesia for awake endotracheal intubation. We prefer this modified spray-as-you-go technique for endoscopic intubation to classical bolus application because of higher patient satisfaction and better compliance.

Over the past few years, new generation endoscopes have emerged as important diagnostic research aids for evaluating murine colitis and colorectal tumors. We present herein a detailed protocol for endoscopic assessment of inflammation and colorectal tumors in mice, as well as a novel scoring system that uses decimal identifiers to document the endoscopic severity of colitis and colorectal tumors.

The use of pigs in research has increased in recent years. Nevertheless, pigs are characterized by difficult airway anatomy. By demonstrating how to perform endoscopically guided endotracheal intubation, the present protocol aims to further increase laboratory animals' safety to avoid animal suffering and unnecessary death.

The ability to assess executive functions such as behavioral flexibility in rats is useful for investigating the neurobiology of cognition in both intact animals and disease models. Here we describe automated tasks for assessing strategy shifting and reversal learning, which are particularly sensitive to disruptions in prefrontal cortical networks.
FAQs
Steerability lets clinicians advance the insertion tube while angling its tip toward areas of interest. Direct visualization from the camera or fiber-optic imaging bundle helps guide these movements during examination. This combination of controlled motion and continuous viewing allows clinicians to inspect tissue and position the instrument for sampling or treatment rather than relying on access alone.
The working channels extend the instrument’s capabilities beyond viewing. They can accommodate instruments and support suction or irrigation, allowing clinicians to obtain biopsies, remove lesions, or carry out minimally invasive treatment while observing the target. Their role is especially important when a procedure requires tissue collection or an intervention during the same examination.
Compared with open procedures, flexible endoscopy reaches internal sites through natural openings or small access sites rather than requiring a larger incision. This less extensive access can generally reduce recovery time, while the scope’s imaging and working channels still support diagnostic and therapeutic tasks in selected clinical settings.
A typical examination begins with advancing the insertion tube through the relevant natural opening or access site. Under direct visualization, the clinician steers the tip to inspect internal surfaces. Depending on findings, the same procedure may include biopsy collection, lesion removal, suction, irrigation, or another minimally invasive treatment, combining assessment and intervention.
In medicine, flexible endoscopy can support evaluation and treatment across the gastrointestinal, respiratory, urinary, and reproductive systems. The relevant anatomy determines where the instrument is advanced, while direct viewing helps clinicians examine tissue. Because the system can also carry working instruments, clinicians may move from observation to biopsy or lesion removal within the same procedure.
The procedure provides direct visual access to internal tissue, allowing clinicians to examine areas that would otherwise require more invasive access. Findings can guide tissue sampling, lesion removal, or treatment performed through the instrument. Its value therefore extends beyond visualization: it can link an observed abnormality with an immediate diagnostic or therapeutic action during one minimally invasive examination.
