2025
We present a laparoscopic technique for anatomic S7+S8d resection with right hepatic vein transection, preserving the inferior right hepatic vein and segment S6. Relying on meticulous anatomical landmarks without intraoperative ultrasound, this approach offers a precise and parenchyma-sparing option for dorsally located right-liver tumors, particularly in settings with limited advanced navigation resources.

Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Lateral canthotomy is a potentially eyesight-saving procedure when performed emergently for an orbital compartment syndrome. An orbital compartment syndrome results from a buildup of pressure behind the eye; as pressure mounts, both the optic nerve and its vascular supply are compressed, rapidly leading to nerve damage and blindness if the pressure is not quickly relieved. The medial and lateral...

A high incidence of tumor recurrence after resection of liver metastases remains an unsolved problem. The illustrated mouse model may be useful to investigate the reasons for such recurrences. It combines a liver resection model with intrahepatic tumor cell injection for the first time.
FAQs
Functional cortical mapping helps surgeons distinguish tissue that can be removed from nearby eloquent cortex, meaning cortex essential for important functions. In this region, mapping is particularly relevant because language, executive function, and motor control may be at stake. The information supports a tailored excision, helping the surgical team pursue diseased tissue while limiting avoidable neurological injury.
The inferior frontal gyrus contributes to several functions that are clinically important during surgery. Removing or disturbing nearby functional cortex can therefore produce language impairment, weakness, or changes in executive function. These possible effects explain why surgeons assess the relationship between the abnormal tissue and functional areas before excision rather than treating the lesion’s location alone as sufficient guidance.
A larger excision may remove more abnormal or diseased tissue, but extending the resection can increase the chance of affecting eloquent cortex. Surgical planning therefore weighs the intended treatment benefit against possible language, motor, or executive-function consequences. This balance is central to selecting how much tissue to remove while preserving neurological function as far as possible.
The procedure begins with a craniotomy to provide access to the brain. Surgeons then identify the target lesion and may perform functional cortical mapping to locate important cortex. After establishing the surgical boundaries, they carefully excise the affected tissue. Preoperative planning and postoperative neurological assessment frame the procedure and help evaluate its functional consequences.
This operation may be considered when abnormal tissue is localized to the inferior frontal gyrus and is associated with a selected brain tumor, focal epilepsy, or another localized disorder. The decision depends on whether the lesion can be approached while managing functional risks. Its use is therefore tied to the disorder, its location, and the feasibility of safe tissue removal.
Postoperative neurological assessment examines whether important functions have changed after tissue removal. Clinicians may focus on language, strength, and executive function because impairment in these areas represents a recognized surgical risk for this region. Comparing the patient’s postoperative neurological status with preoperative expectations helps guide outcome evaluation and informs subsequent clinical management.
