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 gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl. Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

A mouse model of human endoscopic skull base reconstruction has been developed that creates a semipermeable interface between the brain and nose using nasal mucosal grafts. This method allows researchers to study delivery to the central nervous system of high molecular weight therapeutics which are otherwise excluded by the blood-brain barrier when administered systemically.

Herniated Intervertebral Disc l: Introduction

2026
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
FAQs
Mechanical pressure can force the mucosa outward when the supporting tissue has become weak or disrupted. Repeated muscular contraction may add recurring stress, encouraging the protrusion to persist or enlarge. These interacting factors help explain why mucosal herniation is best understood as a change in wall mechanics, rather than as an isolated alteration of the mucosal surface.
When the mucosa moves outward through a compromised underlying layer, the surrounding wall architecture can form a localized pouch. In a hollow organ, that pouch may create a space where luminal contents move differently or remain temporarily retained. This structural consequence connects the microscopic tissue disruption with changes that can be observed at the organ level.
The position and extent of weakness influence how far the mucosa projects and whether the result appears as a limited protrusion or a more recognizable pouch. Mechanical forces within a hollow organ also shape the final architecture. Examining these relationships helps investigators connect local tissue damage with broader changes in the organ wall.
Histology allows researchers to examine the mucosal lining and the underlying tissue layers directly. It can show whether the normal wall architecture has been disrupted and whether the mucosa extends into an abnormal location. This microscopic evidence supports interpretation of the structural change and helps distinguish a benign alteration from a lesion that warrants closer pathological attention.
Endoscopy provides a direct view of the lining and any visible pouch-like alteration, while imaging helps evaluate the structure of the organ wall and surrounding anatomy. Using these approaches together can connect surface appearance with deeper architecture. The resulting information supports detection, characterization, and comparison of structural changes that may not be fully assessed by one method alone.
The process links tissue weakness, mechanical forces, and organ-level architecture, making it useful for studying how structural abnormalities develop. In gastrointestinal research, investigators can also examine how altered wall geometry affects movement or retention of luminal contents. Pathological assessment then helps determine whether the finding represents a benign structural change or a clinically significant lesion.
