A General Practioner may be prosecuted following a botched circumcision of a four-year-old boy.
Health and Disability Commissioner Ron Paterson says the matter has been referred to the Medical Council and the Ministry of Health.
The commissioner found the GP failed to provide services of an appropriate standard by choosing to carry out the circumcision, through his management of the boy during the operation and the inadequacy of information provided to his parents.
In another case, Mr Paterson found a urological surgeon breached the Code of Health and Disability Services Consumers' Rights when operating on a man with prostate cancer.
The patient underwent an operation on his prostate, during which he developed deep vein thrombosis and now has ongoing problems.
The commissioner found the urological surgeon failed to inform the man of his limited experience performing the procedure and the complications that could occur if the operation was subsequently prolonged.
