Laparoscopic cholecystectomy is a commonly used procedural procedure for removal of the gallbladder. Following this healing, wound healing, scar formation and scar tissue formation are critical factors in the healing process. The development of painless, noninvasive, biophysical therapeutic interventions has become the focus of current biomedical research. In recent years, it has been reported that infrared (IR) LED light applications have positive effects on tissue healing processes. This study will be conducted in a randomized controlled manner to examine the effect of postoperative IR LED application on wound healing, scarring and scar tissue formation in patients who underwent laparoscopic cholecystectomy.The research will be carried out at Erzurum City Hospital General Surgery Clinic between 15.08.2024-30.08.2025. A number sequence will be created for the 80 patients in the sample who meet the inclusion criteria for the experimental group and control group, and they will be assigned to the experimental (n = 40) and control groups (n = 40) using a computerized randomization program (https://www.random.org/integer-sets/) patient distribution will be provided. First of all, IR LED light application; It is applied on Post-Operative Day 1 and postoperative day 2. It will be given four times in total, from a distance of 45-60 cm, for 20 minutes at 8 hour intervals. On the 15th and 30th post-operative day, the patient will be asked to come to the hospital and the wound site will be re-evaluated and the data collection form will be filled out again. The patient's pain status will be evaluated with VAS, and satisfaction with Newcastle Nursing Care Satisfaction Scale. Wound and scar tissue will be examined with the Bates Jensen wound assessment scale and the patient and observer scar assessment scale. Wound and scar sites will be re-evaluated after the 15th and 30th post-operative day. The patient's pain status will be evaluated with VAS, and satisfaction with Newcastle Nursing Care Satisfaction Scale. Wound and scar tissue will be examined with the Bates Jensen wound assessment scale and the patient and observer scar assessment scale. The wound margin will be measured with a disposable ruler. In coding and evaluating the data; SPSS 22.00 package program will be used.
