An anal fistula is a tunnel connecting an infected gland within the anus to an opening on the skin surrounding the anus. The common symptoms of the condition are pain and swelling around the anus. 

According to Dr. Purnendu Bhowmik, a fistula doctor in Kolkata, surgery is the only option to cure anal fistula effectively. There are several surgical treatments available. However, among these, laser treatment is preferred by both surgeons and patients. 

Here is everything you need to know about fistula laser treatment in Kolkata

How is an anal fistula laser therapy performed?

Due to its benefits and effectiveness, fistula laser surgery is gaining popularity in India. During the operation, surgeons use a thin laser probe to inject precise laser energy into the fistula tract. After injecting the laser, the fistula tissues are destroyed and the laser probe is withdrawn, closing the tract.

As the laser procedure is precise, it leaves the surrounding healthy tissues intact. Compared to traditional methods, the operation time and the recovery are faster and more comfortable, in the case of laser surgery. 

Fistula laser treatment benefits

  • Short procedure
  • Minimally invasive 
  • Faster healing time than conventional surgery
  • Faster recovery 
  • Daycare procedure
  • Painless procedure
  • Post-surgery complications are lesser
  • Chances of recurrence are negligible


The recovery time following fistula laser treatment in Kolkata is short and pain-free. The fact that this is a minimally invasive daycare procedure means that patients are able to return home the same day that the procedure is performed. They will be able to resume their normal activities after 2-3 days.

However, patients should make sure to avoid strenuous activities until their doctor suggests otherwise.

Although there are no dietary restrictions, Dr. Purnendu Bhowmik, a fistula surgeon in Kolkata, recommends avoiding spicy food and following a high-fibre diet to facilitate easy bowel movements.

Patients who have undergone surgery must follow the post-operative instructions provided by their healthcare provider once they have returned to their homes after the procedure. It is critical to follow all diet and exercise recommendations in order to recover as quickly as possible.

  • Intense pain and discomfort
  • Vomiting or nausea
  • Constipation (no bowel movement for three days or more)
  • Difficulty urinating
  • Fever
  • Anal region redness, swelling, or pain
  • Swelling of the groin lymph nodes
