Background: Frameless stereotaxy is an established method for real-time image-guided surgical navigation in neurological surgery. Though this is capable of providing sub-millimeter accuracy, it has not been used by other surgical specialists.
Methods And Procedure: A patient with locally advanced, distal rectal cancer and tumor abutting the prostate was selected for transanal TME using TAMIS, with intra-operative CT-guided navigation to ensure an R0 resection.
Results: The use of stereotactic TAMIS-TME was successfully performed with an accuracy of ±4 mm. The surgical specimen revealed an R0 resection, and this new approach aided in achieving adequate resection margins.
Conclusion: This is the first report of the use of frameless stereotactic navigation beyond the scope of neurosurgery. Stereotactic navigation for transanal total mesorectal excision is shown to be feasible. Stereotactic navigation may potentially be applied toward other pelvic and fixed abdominal organs, thereby opening the gateway for a broader use by the general surgeon.

Stereotactic systems have traditionally used Cartesian coordinate combined with linear algebraic mathematical models to navigate the brain. Previously, the development of a novel stereotactic system allowed for improved patient comfort, reduced size, and carried through a simplified interface for surgeons. The system was designed with a work envelope and trajectory range optimized for deep brain stimulation applications only.

Background: Parafalcine subdural hematomas (pSDHs) are a subtype of subdural hematoma (SDH) that occur most frequently in older patients after blunt trauma. The literature primarily describes two clinical courses for patients with pSDH: those who are neurologically intact with stable examinations and imaging and those with focal deficits, with or without hematoma progression. Surgical management is undoubtedly required for the latter group; however, there are no evidence-based guidelines specifically for pSDH.

Unlabelled: Brain morphology understanding is essential for radiologists, neurologists, and neurosurgeons. Historically, anatomical learning of brain relied on ex vivo specimens. Modern in vivo brain CT and MRI provide spatial, three-dimensional imaging capabilities crucial to help diagnose diseases, plan surgeries, and monitor treatment progress.
