trisegmentectomy

Trisegmentectomy is a surgical procedure involving the removal of three distinct anatomical segments of an organ. While the term can be applied to various organs, it is most commonly encountered in the context of liver surgery. In liver trisegmentectomy, the surgeon removes three of the liver's eight segments. This is a complex procedure that requires precise identification and dissection of the hepatic vessels and bile ducts associated with the targeted segments.

The decision to perform a trisegmentectomy is typically based on the location and size of a tumor or other lesion within the liver. The goal is to achieve a complete resection of the diseased tissue while preserving as much healthy liver function as possible. This is crucial, as the liver has a remarkable capacity for regeneration, but removing a significant portion can still impact its overall function.

The procedure is performed under general anesthesia and involves making an incision to access the abdominal cavity. Advanced imaging techniques, such as intraoperative ultrasound, are often used to accurately delineate the boundaries of the segments to be removed. Following resection, the remaining liver tissue is reconstructed. Potential complications can include bleeding, bile leakage, and liver insufficiency. The recovery period varies depending on the patient's overall health and the extent of the surgery.
