Former patients of a surgeon who has been struck off say their lives have been ruined by his misconduct.

His firm has been contacted by 193 former patients in total, he said.
ESNEFT said it had carried out its own internal investigation but did not respond when asked if it had undertaken a recall.
The trust invited the Royal College of Surgeons to conduct what is known as an "invited re and Twitter. If you have a story suggestion email eastofenglandnews@bbc.co.uk
