On this resource, the following formatting is used for comprehensiveness:
- Minimal depth
- (Moderate depth)
Steps are as follows:
- (Review operative notes or preoperative radiological studies.)
- ((Photograph the specimen.))
- Measure the specimen
- Probe for any tract
- Inspect, with particular focus on any visible mucosa adjoining the fistula, looking mainly for friable areas or ulcers. Usually there is limited mucosa.
- If successfully probed, dissect longitudinally with a pediatric or finer scissors along the inserted probe.
- If an area of friability and/or ulceration is found, submit that entire area.
- Otherwise, submit one or two representative sections.
- Viral cytopathic effects, especially that of cytomegalovirus.
