Gaby Scanlon was celebrating her birthday with friends when she said she drank two shots of the liquer Jagermeister, and the chemical substance.
Gaby said her stomach began to expand after the night out at Oscar's Wine Bar in Lancaster in October 2012.
Gabby was taken to Lancaster Royal Infirmary where a CT scan found a large perforation.
Miss Scanlon, an A-level pupil at Ripley St Thomas Academy in Lancaster, spent three weeks in hospital.
Doctors removed her stomach and connected her oesophagus directly to her small bowel.
She is now severely limited in what she can eat and faces a life on vitamin supplements and liquid replacement meals.
She told the Mail in 2012: "I try to stay strong. I'm an optimistic person.
"It could have been very much worse and I'm very grateful to be alive."
Today Lancaster City Council announced that court proceedings will take place against the George Street wine bar, one of its directors and an employee.
It is not illegal to serve cocktails containing liquid nitrogen but health and safety laws mean that bars and their employees are under a duty not to expose people to risks to their health and safety.
