Robotic computed tomography-guided celiac plexus neurolysis: our experience of technique and outcomes.

We report the use of robot assistance for computed tomography-guided celiac plexus neurolysis for the first time. Four patients of upper abdominal cancer with intractable pain despite opioids were positioned prone on the PET-computed tomography scanner, which measured the accurate coordinates for the entry, depth and angle of the target point. The robot positioned its arm over the patient in accordance with the set needle path. The physician manually inserted needle through it and injected 20 ml of 0.75% alcohol after dye confirmation. Significant reduction in pain scores and oral morphine consumption were observed in patients during 3 months follow-up. The robot precisely orients and helps in accurate placement of the needle through the robotic arm.
