An operation on a seven-year-old boy at the centre of a legal dispute over cancer treatment went well, a High Court judge has been told.
Neon Roberts underwent more surgery on a brain tumour on Wednesday against his mother's wishes.
Sally Roberts, 37, wanted a delay until more doctors had been consulted.
A High Court hearing into whether he should have other treatment has resumed, with doctors saying a delay in treatment would worsen his prognosis.
Addressing the hearing in London, Ian Peddie QC, for Ms Roberts, said: "The mother is happily relieved to report that the operation went well."
Counsel for the NHS trusts said that, when Neon underwent surgery, evidence was found of a tumour nodule which had been predicted.
However, tests on spinal fluid had shown no evidence of cancerous cells elsewhere.
Brain damage concerns
Doctor giving evidence for treatment said they believed it would not be in Neon's interests to delay preparation for radiotherapy as it would worsen his prognosis.
The court also heard that Mrs Roberts had refused permission for her son to be given medicine in the last few days to stop him vomiting.
Mr Justice Bodey said he was minded to make a default ruling on Neon's continuing treatment unless Mrs Roberts could produce someone who could offer other treatment that was in Neon's best interests.
A further ruling is expected to be made by the end of week on additional treatment for Neon, such as radiotherapy.
The NHS asked for a final order to be made on Thursday.
Mrs Roberts wanted to seek an adjournment until January, but that was rejected by Mr Justice Bodey.
On Tuesday, the judge ruled Wednesday's surgery should go ahead after an MRI scan revealed a residual tumour left from the boy's last operation.
A doctor told the court it was "highly likely" Neon would die within a "relatively short period" without further treatment.
Mrs Roberts previously told the court she was not a "bonkers mother" and she feared treatment such as radiotherapy could do Neon long-term harm including causing brain damage or infertility.
Earlier in the month New Zealand-born Mrs Roberts went into hiding with her son, sparking a nationwide search before both were found unharmed.
A judge has previously ruled that the hospital should not be identified.
