More women treated by a now-banned gynaecologist employed across four of the state's hospitals for more than two decades are expected to come forward, the NSW health department says.
The NSW Civil and Administrative Tribunal earlier this month found Emil Gayed guilty of misconduct while working at Manning Base Hospital on the NSW mid-north coast.
His work was suspended in February 2016 and the tribunal has since banned him from practising medicine.
The complaint alleged that Dr Gayed was guilty of unsatisfactory professional conduct and professional misconduct in relation to his clinical examination and management of seven patients over a three-year period, according to the Health Care Complaints Commission.
He was accused of failing to diagnose a 10-week pregnancy, telling a patient she had cervical cancer when there was no evidence of malignancy and unnecessarily removing a patient's right ovary and fallopian tube, NSW Health said in a statement.
Dr Gayed also worked at Cooma, Kempsey District and Manning Base hospitals between 1994 and his 2016 suspension.
NSW Health has launched a review into the oversight of the care and safety of the patients he treated.
A department spokesman on Tuesday told AAP they are "confident more people will come forward".
NSW Health deputy secretary Nigel Lyons on Monday said he was "very sorry" some women treated by Dr Gayed did not receive quality and safe care.
He said each of the four hospitals will make direct contact with any patient who had raised concerns about the treatment they received from the now-banned doctor.
The inquiry, led by Gail Furness SC, will look at the management of complaints, adverse events and performance issues relating to Dr Gayed.
Ms Furness is due to report back by September 30.
Dr Gayed is still listed on the online practitioner database HealthEngine as a male gynaecologist and obstetrician, based in the Sydney suburb of Dee Why, who speaks Arabic and English.
