You need to consult a general surgeon

Would like to discuss in details and provide apt solution. Kindly consult.

So your query is 'What is meant by lower rectum is opacified?' Normally our rectum is radiolucent as xray can pass through it. In fistulogram a special dye in used through which xray cannot pass just like our bone & comes white. So, some dye is there in your rectum. You have no need to worry about the opacity just visit a surgeon for that fistula. Thats all. Stay healthy.

Consultation with a radiologist is advisable

It must be a simple fistula measuring 6.75cms needs fistulectomy. Lower rectum must be opacified because of the dye injected.
