Performance characteristics of near‐infrared indocyanine green perfusion assessment and subsequent change in planned anastomotic site
| No. of patients* (n = 504) | |
|---|---|
| Failure to acquire NIR image | 0 (0) |
| Duration of each NIR image acquisition (min)† | 4 (1–20) |
| Time to visualization of ICG fluorescence in the anastomosis (s)† | 29 (10–158) |
| Quality of ICG perfusion before anastomosis | |
| Satisfactory | 481 (95·5) |
| Unsatisfactory (revision of decision to proceed) | 23 (4·5) |
| Quality of ICG perfusion after anastomosis | |
| Satisfactory | 503 (99·8) |
| Avoidance of proximal defunctioning ileostomy in patients undergoing LAR | 5 of 90 (6) |
| Unsatisfactory, leading to change of plan (redo anastomosis) | 1 (0·2) |
| Global intraoperative change of plan owing to NIR‐ICG finding | 29 (5·8) |
| Leak rate in patients in whom NIR‐ICG led to change of plan | 0 of 29 |
