What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only

Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study aimed to create a computer program that can automatically identify arteries and bones from ultrasound images taken during surgery. The goal is to make surgical navigation more accurate and efficient, potentially replacing CT scans. Fifty adults with abdominal cancer who were scheduled for surgery participated. The study focused on developing and testing the algorithm, not on treating the cancer itself.

Inclusion Criteria: * ≥ 18 years old * Scheduled for laparotomy (first 30 patients) or robotic assisted lymph node dissection (second 20 patients) * A clinical pre-operative CT scan is available * Patient provides written informed consent Exclusion Criteria: * Metal implants which could influence the 3D modelling or tracking accuracy * Patients with a pacemaker or defibrillator * Patient received treatment, e.g. surgery or radiotherapy, between the pre-operative CT scan and surgery, which might altered the patient's anatomy
