We standardized an abdominal adipose tissue biopsy using a non-diathermy method performed under local anesthesia. Three cases of excessive post-operation bleeding out of 115 operations (2.61%) occurred.We conclude that an abdominal adipose tissue surgical biopsy using a non-diathermy method can be safely applied to healthy men.

This video demonstrates the hemocyte disturbance assay, evaluating hemocyte re-adhesion in Drosophila larvae's hematopoietic pockets. Mechanical disturbance releases resident hemocytes, elevating circulating hemocyte counts. Post-recovery, re-adherence of resident hemocytes is confirmed, illustrating reversibility.

The cornea is unique in that it lacks vascular tissues. However, robust blood vessel growth and survival can be induced in the cornea by potent angiogenic factors. Therefore, the cornea can provide with us a valuable tool for angiogenic studies. This protocol demonstrates how to perform the mouse model of cornea pocket assay and how to assess the angiogenesis induced by angiogenic factors using this model.

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...

2023
Source: Joseph Donroe, MD, Internal Medicine and Pediatrics, Yale School of Medicine, New Haven, CT Abdominal pain is a frequent presenting concern in both the emergency department and the office setting. Acute abdominal pain is defined as pain lasting less than seven days, while an acute abdomen refers to the abrupt onset of severe abdominal pain with features suggesting a surgically intervenable process. The differential diagnosis of acute abdominal pain is broad; thus, clinicians must have a...
FAQs
The key mechanical feature is controlled separation between the abdominal skin and fascia. This creates a defined interface in which an implant or biological material can remain positioned rather than being placed directly within deeper abdominal structures. For researchers, that inspectable location also makes local tissue responses easier to follow over time.
Blunt and sharp dissection provide two documented ways to create the space, but the essential mechanism is the same: tissue planes are separated to establish the pocket. The distinction matters procedurally because the operator selects how the planes will be opened, while the resulting site supports placement of the intended device, graft, sensor, or other material.
Closure is more than the final surgical step. It helps secure the implanted material while the separated tissues heal, preserving the intended placement during recovery. Subsequent observation can then distinguish local integration from reactions such as inflammation, infection, or fibrous capsule formation. These findings help investigators interpret device performance and biological compatibility.
A typical workflow includes creating the pocket by blunt or sharp dissection, positioning the selected material within the space, and closing the incision. The sequence can support drug-delivery devices, infusion pumps, biosensors, tissue grafts, or other implants. Keeping these stages distinct helps relate later observations to pocket formation, material placement, or healing.
Researchers use this site when a study needs a defined subcutaneous location for placing and evaluating an implant or biological material. In medicine and preclinical research, the approach supports investigations of drug delivery, infusion systems, sensing devices, graft behavior, and tissue responses around implanted materials. Its value comes from combining placement with subsequent local observation.
Follow-up may provide information about whether the device is functioning, whether local inflammation or infection develops, and whether tissue integrates with the material. It can also show fibrous capsule formation, giving investigators a way to characterize the local biological response alongside the performance of the implanted system. These observations support evaluation of both function and tissue compatibility.
