Cholestasis is a clinical condition commonly encountered by both surgeons and gastroenterologists. Creation of a reversible cholestatic rat model can be challenging in view of the smaller size and unique hepatopancreatobiliary anatomy in rats. This video article demonstrates the creation of a reversible cholestatic model.

Treating chronic or neuropathic facial pain can be challenging when medical or standard treatment fails. Subcutaneous nerve field stimulation is the least invasive form of neuromodulation and is used for chronic back pain. We applied this technology to treat chronic and neuropathic trigeminal facial pain.

Source: Jakobs, M., et al. Subcutaneous Trigeminal Nerve Field Stimulation for Refractory Facial Pain. J. Vis. Exp. (2017)This procedure demonstrates the implantation of subcutaneous electrodes for trigeminal nerve stimulation to treat neuropathic facial pain. The electrodes are tunneled subcutaneously from the affected facial region to an infraclavicular pocket, where they are connected to an internal pulse generator (IPG). The IPG delivers electrical stimulation, activating mechanoreceptor...

FAQs
Tunnel geometry influences how the device sits within tissue and how forces act on it during use. A planned length and direction can reduce mechanical stress, support secure placement, and help maintain separate, well-positioned openings. These features also contribute to more favorable wound healing and may limit complications associated with poorly aligned or excessively stressed tissue pathways.
Blunt and sharp dissection provide different ways to develop the subcutaneous path, and the selected approach affects how the tissue is separated during surgery. Because limiting tissue trauma is an important goal, the surgeon must create the planned passage while handling tissue carefully. This supports device positioning, wound healing, and the intended function of the routed catheter, drain, graft, or device.
Tissue handling affects the amount of local trauma produced while the passage is formed and the device is advanced. Gentle, controlled development of the route helps preserve the surrounding tissue, which can support wound healing and secure placement. Careful handling also contributes to reducing complications when the tunnel must remain functional for ongoing vascular access, drainage, dialysis, or implanted-device treatment.
Separate entry and exit sites allow the device to follow a planned subcutaneous route rather than concentrating its course at one skin opening. This arrangement can reduce mechanical stress, help limit contamination, and support more stable positioning. When the sites are placed appropriately, they also contribute to wound healing and help the device perform its intended treatment function over time.
The procedure requires planning the passage, selecting blunt or sharp dissection as appropriate, developing the route through the tissue, advancing the device along that path, and positioning its openings. Tunnel length, direction, and tissue handling are key considerations throughout these steps. Together, they influence secure placement, device function, tissue trauma, contamination risk, and wound healing.
This technique supports several types of medical treatment that require a device to pass beneath the skin. Applications include vascular access, peritoneal dialysis, drainage procedures, and implanted-device placement. The specific device may be a catheter, drain, graft, or another medical device, while the planned tunnel helps separate its openings and maintain a route suited to the intended therapy.
An appropriately created tunnel should support secure device placement, preserve the device's intended function, and promote wound healing. Its length and direction should avoid unnecessary mechanical stress, while careful tissue handling should limit trauma. Proper positioning of the openings can also help reduce contamination and complications, making the technique relevant to both short-term procedures and longer-term treatment.
