The decision follows an investigation by the BBC and a review by Southmead Hospital and Spire Hospital, which found more than 200 patients were harmed after Dixon operated on them unnecessarily.
Southmead Hospital’s investigation, in 2023, found non-surgical treatments should have been offered instead.
The BBC first revealed allegations made against Dixon in 2017, when many women complained of severe pain following their operations.
He used a technique known as mesh rectopexy to treat bowel problems.
The tribunal received testimonials that “spoke very highly” of Dixon, including from numerous former patients who said how he helped them, as well as being described as “extremely well thought of by his peers and a leading light”.
However, the tribunal found he had “not taken any steps to remediate his serious misconduct”.
