<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have keloid formation after the heart surgery on the chest. Is it right that I should have injection of Tricot? Is there any side effect, if 5-fluorouracil combined with it ? Should I have cryotherapy as well this this injection? Kindly suggest the right way.  <response>: Hi, Thank you for your query. I can understand your concerns. Intralesional corticosteroid injections StrictTriamcinolonecan be taken if local therapy has failed. Intraluminal injections are more effective on younger scars. When used alone, however, there is a variable rate of response and recurrence. Success is enhanced when used in combination with surgical excision.5-fluorouracil or cryotherapy is not standard treatment. Regards
