Pubic Bone Excision and Perineal Urethrectomy for Radical Anterior Compartment Excision During Pelvic Exenteration.

BACKGROUND

Malignant infiltration of the pubic bone traditionally is considered inoperable. Consequently, there is little published on surgical approaches to resection of the anterior pelvic bone. En bloc partial or complete pubic bone excision can be performed depending on the degree of involvement.

OBJECTIVE

This article describes our surgical approach of pelvic exenteration with en bloc composite pubic bone excision.

DESIGN

The surgical technique describes 2 distinct aspects of the surgery, first, a perineal as opposed to abdominal transection of the urethra, and, second, varying extents of en bloc pubic bone excision.

SETTINGS

This study was conducted at a tertiary care hospital.

MAIN OUTCOME MEASURES

Pelvic tumors infiltrating the pubic bone require radical en bloc composite bone resection to achieve an R0 margin that should translate to longer-term survival versus nonoperative treatments.

RESULTS

Results of our study are currently under review.

CONCLUSIONS

As the magnitude of pelvic exenteration surgery continues to evolve for all compartments of the pelvis, malignant infiltration of the anterior pelvic bone should not be considered a contraindication to surgery.
