(2022)This video demonstrates the use of a minimally invasive resection system (MIRS) to excise tumor tissue from an anesthetized mouse implanted with a tumor. The procedure involves securing the mouse onto a stereotactic frame, reopening the previous surgical site to access the brain, and inserting a specialized cannula that utilizes suction and a...

Endoscopic septoplasty is a time-honored surgical procedure with multiple variations. This paper focuses on a step-by-step surgical approach to perform a modified septoplasty procedure known as limited two-line resection. This surgical technique can be applied to correct a deviated nasal septum in the absence of an external nasal deformity.

Minimally invasive surgical (MIS) procedures rely on anatomical references to localize structures not directly visible to the surgeon. This manuscript describes a combined method of plane-by-plane dissection and sectional anatomy of fresh-frozen specimens to locate the structures at risk during MIS procedures.
FAQs
Patient selection helps balance the intended reduction in tissue trauma against the technical demands of removing liver tissue safely. Surgeons must consider whether the lesion is localized and whether its position allows adequate visualization, vessel control, bile-duct division, and complete removal. Advanced imaging supports this assessment by clarifying liver anatomy and helping plan a safe resection.
Advanced imaging provides preoperative information about the lesion and surrounding liver structures, while the camera supplies direct intraoperative visualization. Together, they help the surgical team identify the planned area, locate relevant blood vessels and bile ducts, and guide the transection. This coordinated assessment supports precise removal and reduces the risk of leaving the targeted lesion behind.
Blood vessels and bile ducts must be identified and divided as part of separating the planned liver portion from the remaining organ. Controlling these structures allows surgeons to transect the selected segment through a defined surgical path. Their careful management is central to safe tissue removal and to achieving a complete resection of the localized disease.
The operation generally proceeds by placing laparoscopic or robotic instruments through small incisions, visualizing the liver with a camera, and identifying the planned resection area. Surgeons then divide the relevant blood vessels and bile ducts, transect the selected liver segment, and remove it through a protected incision. Each step depends on the preoperative plan and intraoperative anatomy.
Laparoscopic or robotic instruments provide the operative access, while a camera supplies visualization inside the abdomen. The removed liver tissue is taken out through a protected incision rather than directly through the small instrument openings. This equipment and access strategy enables the planned surgical tasks while limiting the size of the abdominal incisions used for the procedure.
This approach may be considered for selected patients with certain primary or metastatic liver tumors, as well as other localized hepatic lesions. When appropriate, it can support treatment while potentially reducing postoperative pain, shortening hospitalization, and accelerating recovery compared with the tissue burden associated with a large open abdominal incision. Complete resection remains an essential goal.
