Study on augmented reality for robotic surgery bedside assistants.

Robotic surgery bedside assistants play an important role in robotic procedures by performing intra-corporeal tasks while accommodating the physical presence of the robot. We hypothesized that an augmented reality headset enabling 3D intra-corporeal vision while facing the surgical field could decrease time and improve accuracy of robotic bedside tasks. Bedside assistants (one physician assistant, one medical student, three surgical trainees, and two attending surgeons) performed validated tasks within a mock abdominal cavity with a surgical robot docked.

Maximizing lymph node retrieval during surgical resection of Wilms tumor.

Introduction: Sampling lymph nodes (LNs) is independently associated with decreased recurrence and improved survival for Wilms tumor (WT). Despite sampling, we noted cases where a few or no LNs were identified after resection of WT. We hypothesized fewer LNs were identified when submitted en bloc with the tumor, compared with when submitted separately.
