: of doubt.

To be more specific: One of the 18 are niqvah hakeivah (Chullin 49a).
The keivah is the abomasum, the 4th of a ruminant's stomachs. WRT
matenas kehunah, the keivah includes the fats attached to the
abomasum; I am pretty sure but not certain they are not included here.
(Ie if someone cuts the fats, it would still be kosher.)

There are four different kinds of DA surgery, but all involve (1)
puncturing the keivah to deflate it, and (2) sowing it to the proper
location in the body.

Tir'u baTov!
