Assessment of Postoperative Pain Using Conventional and Tumescent Local Anesthesia in Laser Treatment of Pilonidal Sinus Disease

What this Trial Is About

Researchers are comparing two local anesthesia methods to see their effect on pain after laser treatment for pilonidal sinus disease, a common condition affecting about 2% of the population, mostly men. The study aims to find out if there is a difference in pain levels after surgery using conventional local anesthesia or tumescent local anesthesia, which may provide longer pain relief and reduce bleeding. This is a prospective, randomized study taking place from September 2025 to August 2027 at a general hospital. Participants receive either conventional local anesthesia with 2% lidocaine injected into the surgical area or tumescent local anesthesia, which is a diluted anesthetic solution including lidocaine, epinephrine, and sodium bicarbonate, injected under the skin before laser treatment using a 1470-nm radial-emitting laser fiber. Both groups undergo the same laser treatment for pilonidal sinus. Randomization is done by sealed envelopes prior to surgery. Participants will have their pain assessed using a visual analog scale (VAS) before surgery and on the first, second, and seventh days after surgery. Data on pain scores and demographics will be collected anonymously and assessed without bias. The main outcome measured is pain on the first day after surgery. The study ensures voluntary participation with informed consent, and no additional risks beyond standard care are expected.
