Abstract: ［Abstract］ Objective To investigate the application of an incision along skin line and subcutaneoustissue traction to underbelly surgery. Methods 262 cases of lower abdomen surgery were assigned to observation group including inguinal hernia repair，appendectomy，and hydrocele of hydrocele. This surgical procedure was performed through an incision along skin line and subcutaneous tissue and retraction in our hospital from July 2010 to December 2017. Another 278 patients who underwent conventional surgical incision were used as controls. Incision healing and adverse reactions were recorded and compared between the two groups. Results In patients of observation group，wound infection，wound hematoma，and local edema were less than that in the conventional incision group，and the average suture removal time was shortened，and the scar width was also reduced，and all P value were less than 0.05. Conclusion The transverse incision has a small scar and cosmetic incision. The subcutaneous tissue retraction through transverse incision can avoid damage to the vessels，thus reducing subcutaneous hematoma，wound infection and complications.

摘要： ［摘要］ 目的 探讨皮纹横切口及皮下组织拉牵术在腹股沟区手术的临床应用疗效。方法 探讨 2010 年 7 月～2017 年 12 月期间我院通过皮纹横切口及皮下组织、牵开术来完成下腹部手术， 包括腹股沟疝修补术、阑尾切除术以及交通性鞘膜积液、精索静脉曲张的静脉结扎术等下腹部262 例。另收集278 例同期该类手术采用常规手术切口的患者作为对照，手术后切口愈合情况和不良反应被记录及两组间比较。结果 沿皮纹切口患者中，切口感染、创面血肿、局部水肿均少于常规切口组，同时平均拆线时间缩短，瘢痕宽度也减小（所有P 小于0.05）。结论 皮纹横切口是一种疤痕小且美容的切口；而皮下组织牵开术可以避免血管神经及淋巴管的损伤，故可以减少皮下血肿、切口感染及并发症。
