目的 探索芒硝外敷联合红外线照射促进胆石症手术切口愈合的疗效。 方法 将2022年1月至2025年4月我科收治的胆石症且实施开腹手术的患者随机纳入3个组：（1）联合组（n = 60）：患者术后切口应用芒硝外敷，联合红外线外照射治疗；（2）芒硝组（n = 60）：患者术后切口单纯应用芒硝外敷治疗；（3）红外线组（n = 60）：患者术后切口单纯应用红外线外照射治疗。比较各组术后第7天时患者切口愈合等级，术后第3、5、7天的切口疼痛评分，患者术后至出院切口愈合情况。如果患者出现切口愈合不良，则记录出现切口愈合不良后治疗至切口愈合的时间，患者术后住院时间，术后3个月时切口瘢痕温哥华瘢痕量表包括切口色泽、厚度、血管分布和柔软度4个指标的评分。 结果 联合组切口愈合不良发生率、术后住院时间、瘢痕温哥华评分中瘢痕厚度和柔软度评分，术后第3、5天疼痛评分显著低于其他两组（P < 0.05）。 结论 胆石症术后应用芒硝外敷联合红外线照射手术切口是一种优效、经济、可及的辅助治疗方式，能够降低胆石症患者手术切口愈合不良的发生率，减轻早期术后疼痛，值得临床推广。

Objective To investigate the efficacy of externally applied mirabilite combined with infrared irradiation in promoting wound healing following biliary tract surgery. Methods Patients who underwent open surgery for biliary tract disease in our department between January 2022 and April 2025 were randomly assigned to one of three groups： （1） Combination group （n = 60）， which received postoperative wound treatment with mirabilite application combined with infrared irradiation； （2） Mirabilite group （n = 60）， treated with mirabilite application alone； and （3） Infrared group （n = 60）， treated with infrared irradiation alone. The primary outcomes included wound healing grade on postoperative day 7， pain intensity measured on days 3， 5， and 7， and wound healing status up to discharge. For cases with suboptimal healing， the duration required for complete healing following intervention was documented. Secondary outcomes encompassed length of postoperative hospital stay and Vancouver Scar Scale （VSS） scores—assessing scar pigmentation， thickness， vascularity， and pliability—evaluated at 3 months postoperatively. Results The combination group exhibited significantly lower rates of poor wound healing， shorter postoperative hospital stays， improved VSS scores—particularly in terms of scar thickness and pliability—and reduced pain levels on the 3rd and 5th postoperative days compared to the other two groups （P < 0.05）. Conclusions The combined use of mirabilite and infrared irradiation for surgical incisions following biliary tract surgery represents an effective， economical， and readily accessible adjuvant therapy. It significantly reduces the incidence of impaired wound healing and effectively alleviates early postoperative pain， thereby demonstrating strong potential for clinical promotion.
