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.

Detection of Black Holes

Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s. Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light. Not until the 1960s, when the first neutron...
FAQs
Opening the dura provides a pathway from the skull opening to the intracranial compartment when the target material or monitoring site lies beneath it. Whether this step is necessary depends on the intended purpose of the procedure. The distinction matters because access beyond the skull introduces additional contact with tissues and fluid compartments that normally contribute to intracranial protection.
Removing accumulated blood, cerebrospinal fluid, or infected material can reduce local mass effect and may relieve selected forms of intracranial pressure. The outcome depends on what has accumulated and whether drainage reaches the relevant compartment. Burr hole creation therefore functions as a targeted access route, while the material removed determines the immediate therapeutic objective.
A catheter can maintain a route for continued drainage after the initial opening is made. This is useful when accumulated material requires ongoing removal rather than a single release. Catheter placement also connects the access procedure to monitoring or postoperative management, although the source material does not specify a particular catheter design or duration of use.
Infection prevention depends on maintaining sterile technique while passing through the scalp, skull, dura when opened, and intracranial space. These tissues form protective barriers, so disrupting them creates an opportunity for organisms to reach normally protected compartments. Careful handling of the drill, opening, and any catheter is therefore central to reducing postoperative intracranial infection risk.
The procedure is commonly selected for chronic subdural hematomas, selected cases of raised intracranial pressure, and situations requiring access for monitoring or drainage. Its value lies in providing a small cranial access point suited to these objectives. The appropriate choice depends on the material or pressure problem being addressed and the required intracranial access.
The procedure provides a model for examining how tissue barriers and host defenses respond when intracranial compartments are surgically accessed. It also focuses attention on postoperative infection risk, particularly when blood, cerebrospinal fluid, or infected material is drained and a catheter may remain. These features connect surgical technique with sterile practice and host protection.
