Brief Summary

"Assessment of postoperative pain with conventional and tumescent local anesthesia in the laser treatment of pilonidal sinus." The aim of this study is to: examine the possible difference in postoperative pain between two local anesthesia procedures after laser treatment of pilonidal sinus disease on the first and second postoperative day, as well as one week after surgery. During the procedure, two well-established anesthesia techniques are used to make the surgical area painless. The first is local anesthesia, in which the anesthetic is injected into and under the skin. The second procedure is tumescent anesthesia. In this procedure, the anesthetic in diluted form is introduced into the subcutaneous tissue. Both procedures are used in surgery and are standard methods of local anesthesia.

Outcome Measures

Primary Outcomes (1)

  • Pain score VAS - Day 1

    VAS (visual analog scale for pain) value obtained via questionnaire on day 1 after the operation.The VAS score has a scale of 1-10, where 1 represents completely pain-free and 10 represents the strongest imaginable pain.

    24 to 48 hours after surgery

Study Arms (2)

Conventional local anesthesia for SiLaC

ACTIVE COMPARATOR

Local anesthesia is administered before laser treatment of pinlonidal sinus disease. Postoperative the pain score is measured using the visual analog scale.

Drug: local anesthesia using 2% lidocaineDevice: SiLaCOther: Questionnaire and physical examination

Tumescent local anesthesia for SiLaC

ACTIVE COMPARATOR

Tumescent local anesthesia is administered before laser treatment of pinlonidal sinus disease. Postoperative the pain score is measured using the visual analog scale.

Device: SiLaCOther: Questionnaire and physical examinationDrug: Tumescent local anesthesia

Interventions

Intervention Type: Drug Intervention Name: Lidocaine 2% Description: Conventional local anesthesia using 2% lidocaine infiltrated into the operative field prior to SiLaC.

Conventional local anesthesia for SiLaC
SiLaCDEVICE

Intervention Type: Device Intervention Name: 1470-nm radial-emitting laser fiber (SiLaC) Description: Thermal ablation of pilonidal sinus tracts using a 1470-nm radial-emitting laser fiber (1470 nm) with power adjusted between 8 and 10 Watt.

Intervention Type: Other Intervention Name: Questionnaire and physical examination Description: Postoperative pain evaluation using a visual analog scale (VAS) questionnaire and physical examination.

Conventional local anesthesia for SiLaCTumescent local anesthesia for SiLaC

Intervention Type: Drug Intervention Name: Tumescent local anesthetic solution Description: Tumescent solution prepared with 500 mL normal saline, 20 mL 2% lidocaine, one ampule of epinephrine (1 mg/mL), and 5 mL sodium bicarbonate; infiltrated into the operative field prior to SiLaC.
