Objective:
To assess the effectiveness and safety of modified silicone gel sheets applied to hypertrophic scars and keloids following laparoscopic surgery.
Methods:
Patients who had undergone laparoscopic surgery and who had either conventional or modified silicone gel sheets affixed to their surgical lesions for 6 months postoperatively (treatment groups), and control patients who had not received postsurgical treatment involving silicone gel sheets, were enrolled. The surgical wounds were assessed visually and using the Japan Scar Workshop (JSW) Scar Scale. Patients were interviewed before, 3 months after, and 6 months after sheet affixation.
Results:
A total of 45 patients were included, comprising 15 patients per group. Both silicone gel-sheet groups had significantly lower JSW Scar Scale scores at 3 and 6 months after affixation compared with controls. The scores were not significantly different between the conventional and modified treatment groups and no adverse events were observed in the latter.
Conclusions:
Modified silicone gel sheets were more effective than controls and comparable to conventional gel sheets, and there were no adverse events related to laparoscopic surgical wounds in the improved silicone gel sheet group, demonstrating the safety and effectiveness of the modified silicone gel sheets.
