multivisceral resection
Surgical removal of a primary tumor along with adjacent organs or structures to achieve negative margins in locally advanced cancers.
Full Definition
Multivisceral resection refers to the surgical approach where a primary tumor is removed en bloc with one or more adjacent organs or structures to achieve complete oncologic resection. This technique is employed when tumors have invaded or are adherent to neighboring structures, making it impossible to achieve negative margins with standard organ-specific resections. Common examples include colorectal cancers requiring removal of adjacent small bowel, bladder, or reproductive organs. While multivisceral resections increase operative complexity and morbidity, they can provide curative treatment for locally advanced cancers that would otherwise be unresectable. Careful preoperative planning and multidisciplinary coordination are essential for optimal outcomes.
Usage
