Comparison between EMTS tip location and radiograph tip location
| A: Postprocedure EMTS tip location immediately after placement and radiograph tip location within 5 hours of placement | ||||
| EMTS screen tip location immediately after placement | Radiograph tip location within 5 hours* after placement | |||
| Stomach | Pylorus region | Small intestine | Total by EMTS | |
| Stomach | 22† | – | 2 | 24 |
| Pylorus region | – | 9 | – | 9 |
| Small intestine | – | – | 25 | 25 |
| Total by radiograph | 22 | 9 | 27 | 58 |
| B‡: EMTS tip location and radiograph tip location at the follow-up visit (12–49 hours after placement of the feeding tube) | ||||
| EMTS screen tip location at follow-up visit | Radiograph tip location at follow-up visit | Total by EMTS | ||
| Stomach | Pylorus region | Small intestine | ||
| Stomach | 16† | 1 | 1 | 18 |
| Pylorus region | 1 | 3 | – | 4 |
| Small intestine | 1 | 1 | 24 | 26 |
| Total by radiograph | 18 | 5 | 25 | 48 |
*The protocol allowed for a 5-hour window for radiographic confirmation of EFT placement to account for radiology’s schedule.
†Shaded values represent complete agreement between tip location according to the EMTS and radiography.
‡Note that table 2B includes the 48 patients who had both EMTS and radiography evaluations at follow-up. The patient who had EMTS evaluation but not radiography is not included.
