切口脂肪层下放置负压引流管对结肠造瘘口回纳手术患者切口愈合的影响

Effect of vacuum sealing drainage tube placed under the fat layer of incision on incision healing in patients with return operation for colostomy

目的探讨切口脂肪层下放置负压引流管对结肠造瘘口回纳手术患者切口愈合的影响.方法选取49例结肠造瘘口回纳手术患者,对照组25例在用生理盐水冲洗切口后不放置引流管引流,观察组24例在用生理盐水冲洗切口后于脂肪层下方放置负压引流管引流.结果观察组愈合时间(7.2±1.2)d,显著短于对照组的(11.5±2.1)d(P<0.05).观察组愈合评级为甲级20例,乙级4例,丙级0例;对照组愈合评级为甲级14例,乙级7例,丙级4例.观察组愈合情况显著优于对照组(P<0.05).结论皮下脂肪层放置负压引流管能有效降低结肠造瘘口回纳手术后的切口感染率,提高切口愈合率,缩短住院时间.

Objective To investigate the effect of vacuum sealing drainage tube placed under the fat layer of the incision on the incision healing in patients with return operation for colostomy.Methods Totally 49 patients with return operation for colostomy were selected.Control group(n=25)was conducted with normal saline washing without placing of drainage tube,while observation group(n=24)was treated with vacuum sealing drainage tube placed under the fat layer of the incision after washing the incision with normal saline.Results The healing time of the observation group was(7.2±1.2)d,which was significantly shorter than(11.5±2.1)d of the control group(P<0.05).In the observation group,there were 20 cases of grade A of healing,4 cases of grade B and 0 case of grade C.In the control group,there were 14 cases of grade A,7 cases of grade B and 4 cases of grade C.The healing status of the observation group was significantly better than that of the control group(P<0.05).Conclusion Placing vacuum sealing drainage tube in subcutaneous fat layer can effectively reduce the infection rate of incision after return operation for colostomy,improve the healing rate of incision and shorten the hospital stay.
