Zici, Seppuku, and ...

Well, everyone knows Japanese bushi commit suidice by cutting his stomach, and it's called seppuku. Cutting one's stomach as a suicide method is called Zici in China, and was practiced until Eastern Han dynasty, and reappeared in Sui and Tang dynasty. The most famous case of Zici is Nie Zheng, who committed it after assassinated the King and Prime Minister of Han, as show in the Han-period wall painting:


After Western Han, zici was no longer practiced (as it's considered inhumane). But it reappeared during Sui and Tang dynasty, people had suggested it's due to Sogdian influence.  Zici again went 'out of fashion' after Tang.

My question: was slashing one's stomach a suicide method used in Korea? If it was, how it's called? and was it a common method or it's very rare?

I knew one Kogoryo general (second son of Yeon Gaesomun 연개소문 ) did commit suicide by slashing his stomach after fall of Pyongyang, but wonder whether it's just a Kogoryo thing.
