Why does sticky pus discharge happen while passing gas after fistula laser treatment?

Mild sticky or pus like discharge after fistula laser treatment can sometimes occur during the healing phase, especially in the first few weeks after surgery. Some patients may notice slight discharge while passing gas or after bowel movements because the treated fistula tract is still healing internally. Mild moisture, staining, or occasional discomfort can be part of the recovery process in some cases.

However, persistent pus discharge, foul smell, increasing pain, swelling, fever, or continuous leakage should not be ignored, as these symptoms may suggest infection, delayed healing, or recurrence of the fistula. We recommend a follow up examination with your surgeon to assess the healing properly and ensure there are no complications. Maintaining hygiene, following wound care instructions, and attending regular follow ups are important for smooth recovery.
