Bile Duct Imaging With Conventional and Indocyanine Green Near-Infrared (ICG-NIR) Imaging at Each “Look.”
| Look 1a | Look 2b | Look 3c | |
|---|---|---|---|
| No. of patients | 18 | 6d | 18 |
| Time after ICG injection, minutes, median (min-max) | 30 (20-72) | 70 (28-91) | 51 (10-117) |
| Bile duct imaging | 7 | 4 | 18 |
| Conventional imaging | |||
| Cystic duct (CD) | 3 | 3 | 18 |
| Common bile duct (CBD) | 0 | 0 | 3 |
| No visualization of bile ducts | 15 | 3 | 0 |
| ICG-NIR imaging | |||
| Cystic duct (CD) | 4 | 2 | 13 |
| Common bile duct (CBD) | 2 | 2 | 7 |
| No visualization of bile ducts | 13 | 4 | 5 |
a
After incising the peritoneal fold in the hilus of the gallbladder and before dissection of Calot’s triangle.
b
After the first look before skeletonizing of structures and only performed if the cystic duct could not be visualized at the first look.
c
When critical view of safety was reached with conventional imaging.
d
A second look was planned in 11 patients but performed in just 6 patients. In 5 patients, critical view of safety was reached quickly after the first look before a second look could have been performed.
