About

The goal of this observational pilot study is to evaluate the feasibility and accuracy of tracked ultrasound registration on patients undergoing abdominal cancer navigation surgery. The main research question is: Could tracked ultrasound be applied as an alternative to standard CBCT scanning in surgical navigation? Participants will undergo tracked ultrasound measurements of the pelvic bone on the operating room after patient anesthesia and before surgical incision.

Full description

Image-guided navigation surgery allows for full utilization of pre-operative imaging during surgery and has the potential of reducing both irradical resections and morbidity. Currently, registration is done by Cone-Beam CT (CBCT) scanning on the operating room (OR) prior to navigation surgery. However, standard CBCT scanning has several limitations, mainly limited availability on the hybrid OR and radiation exposure. Furthermore, standard CBCT scanning can only be performed in horizontal patient position, while the patient position mostly differs during surgery, such as the Trendelenburg position. The use of tracked ultrasound instead of standard CBCT could overcome these limitations, which might lead to an increased navigation accuracy and improved surgical outcomes. Therefore, the goal of this research is to evaluate the feasibility and accuracy of tracked ultrasound registration on patients undergoing abdominal cancer navigation surgery. The main research question is: Could tracked ultrasound be applied as an alternative to standard CBCT scanning in surgical navigation?

Patients scheduled for navigated abdominal cancer surgery

Description:

Patients are 18 years old or older. Patients are scheduled for tumor surgery in the abdominal/pelvic area and navigation surgery with a scheduled Cone Beam CT-scan in the operating room. Patients provide written 'informed consent'. The to be administered intervention is a percutaneous tracked ultrasound measurement of the patient's pelvic bone on the operating room after anesthesia.

Treatment:

Device: Tracked ultrasound measurement
