目的：探讨腹部脂肪层自然对合对肥胖患者妇科腹部手术术后切口脂肪液化的预防作用。方法选取肥胖的妇科手术患者357例为研究对象，分为研究组（185例）及对照组（172例），两组腹壁脂肪层分别采取自然对合处理及间断缝合处理。比较两组患者手术时间，术后切口脂肪液化发生率、切口愈合情况。结果研究组切口脂肪液化发生率明显小于对照组(P<0.05)。切口甲级愈合率明显高于对照组(P<0.05)，手术时间明显短于对照组。结论腹部切口脂肪层自然对合可有效预防肥胖患者妇科腹部切口脂肪液化的发生，促进切口愈合。“,”Objective To observe the efficacy of abdominal fat natural involution on incision of fat patients after obesity operation Methods 357 fat patients with gynecological operation was selected randomly and divided into the study group (185 cases) and control group (172 cases), The patients of two groups were respectively take the natural involution and interrupted suture treatment. Compared the operation time, occurrence rate of incision fat liquefaction, wound healing of two groups . Results The occurrence rate of incision fat liquefaction of study group was significantly less than that of the control group (P<0.05). The grade A healing rate was significantly higher than that of the control group (P<0.05), The mean operation time of study group was shorter than the control group (P<0.05), Conclusions Abdominal fat natural involution is one of the efficient methods of preventing incision fat liquefaction of fat patients with obesity operation .
