'''Intraoperative consultation''', also '''quick section''' and '''frozen section''', is when a surgeon requests an opinion during an operation so that they can appropriately manage a patient. It is abbreviated '''IC'''. Frozen section is often abbreviated '''FS'''. | '''Intraoperative consultation''', also '''quick section''' and '''frozen section''', is when a surgeon requests an opinion during an operation so that they can appropriately manage a patient.

===Endometrial carcinoma=== | |||
===General=== | |||
*Diagnosis usually known before the surgery. | |||
*The IC revolves around whether the lesion has a "high risk" of [[lymph node metastasis]]. | |||
Factors that increase the risk of lymph node metastases:<ref>{{Ref BITFS|43}}</ref> | |||
*Histology: | |||
**Serous or clear cell. | |||
**FIGO grade 3. | |||
*Staging parameters - involvement of: | |||
**Outer half of the myometrium. | |||
**Uterine cervix. | |||
**Adnexa. | |||
===Checklist=== | |||
Gross assessment: | |||
*Uterine cervix involvement (rare). | |||
*Adnexal involvement (rare). | |||
*Myometrial involvement - after sectioning bivalving and sectioning (with a 5 mm interval). | |||
===Parathyroid gland=== | |||
{{Main|Parathyroid gland}} | |||
Possibilities: | |||
*Parathyroid gland: † | |||
**Benign parathyroid gland. | |||
**[[Parathyroid adenoma]]. | |||
**[[Parathyroid hyperplasia]]. | |||
**[[Parathyroid carcinoma]]. | |||
*Thyroid gland. | |||
*[[Lymph node]]. | |||
*Fibroadipose tissue. | |||
*[[Paraganglioma]]. | |||
Notes: | |||
* † It is ''not'' possible to determine which one without history ''or'' all parathyroid glands. | |||
* Surgeons are pretty good at identifying parathyroid tissue ~ 94% accurate in one series.<ref name=pmid16360503>{{Cite journal | last1 = Dewan | first1 = AK. | last2 = Kapadia | first2 = SB. | last3 = Hollenbeak | first3 = CS. | last4 = Stack | first4 = BC. | title = Is routine frozen section necessary for parathyroid surgery? | journal = Otolaryngol Head Neck Surg | volume = 133 | issue = 6 | pages = 857-62 | month = Dec | year = 2005 | doi = 10.1016/j.otohns.2005.05.001 | PMID = 16360503 }}</ref> | |||
