This randomized controlled study aims to evaluate the effect of local heat application to the feet on postoperative pain and abdominal distension in patients undergoing open or laparoscopic cholecystectomy. Eligible participants will be randomly assigned to either a local heat application group or a control group. In the intervention group, heat will be applied to the feet using a hot-water bottle for 15 minutes at hourly intervals during the first four postoperative hours. Pain and abdominal distension will be assessed using validated scales, and gastrointestinal recovery indicators such as time to first flatus and defecation will be recorded. The study is designed to determine whether this simple, nurse-led, non-pharmacological intervention may improve postoperative comfort and recovery.
