• 8K laparoscopic images were excellent in reproducing the
appearances of solidity and reality.
• They could clearly recognize vessels on the multilayer mem-
brane around the bile duct and the gallbladder.
• Viewing of 8K laparoscopic images caused less eyestrain.
On the other hand, they also reported the following negative
evaluations:
• Without sufficient illumination, the darkness and low quality of
color reproduction of the images made laparoscopic surgery
impossible.
• The large size of the 8K camera head interfered with the surgi-
cal field.
• The weight of the heavy 8K camera head made it difficult to
hold in position even by 2 laparoscopists.

visualization. A recent study found that fluorescence imaging could
help prevent bile duct injuries in complicated cholecystectomies
(osmag.net/X7UeTg).
Dr. Eun uses the technology extensively in his urological robotic
cases. During complex repairs, he'll inject ICG solution directly into
the ureter in an off-label use that's becoming more common among
surgeons. He can then visualize the ureter clearly using NIRF imaging
and avoid damaging it. He also uses NIRF imaging in cases where he
needs to determine if tissue has good blood supply.
"When we're looking at a piece of tissue during repairs, we can easily
check the blood supply," he says. "If it lights up green, then it's a confir-
mation that that piece of tissue is well perfused. Before, we had to judge
these situations using only the naked eye."
