Present on all resections to document the presence or absence of tumour and/or viability of the resection margin
En face (shave, parallel)
Advantages
- more surface area
- entire structures can be evaluated (e.g., bronchus, ureter)
Disadvantages
- cannot measure the exact distance
- can be difficult to interpret when cautery artifact is present
Perpendicular
Advantages
- exact distance can be measured
Disadvantages
- very little tissue is evaluated in larger resections
Rule of thumb
