ABSTRACT
Objective To assess the influence of full-thickness continuous suture method and layer interrupted suture method in emergency abdominal operation closure.Methods Two hundred and thirtyseven patients of emergency abdominal operation were divided into full-thickness continuous suture method group (145 cases) and layer interrupted suture method group (92 cases) according to the suture method.The rate of incision liquefaction and infection,time of incision suture were compared between the 2 groups,the patients with incision liquefaction and infection were given bacterial culture.Results The time of incision suture in full-thickness continuous suture method group was significantly shorter than that in layer interrupted suture method group [(18.37 ± 7.42) min vs.(25.92 ± 5.79) min],there was statistical difference (P ＜0.01).There were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing between the 2 groups (P ＞ 0.05).In full-thickness continuous suture method group,the rate of incision liquefaction and infection in median incision was significantly lower than that in rectus abdominis incision [18.58％ (21/113) vs.31.25％ (10/32)],the rate of incision primary healing was significantly higher than that in rectus abdominis incision [81.42％ (92/113) vs.68.75％ (22/32)],there were statistical differences (P ＜ 0.05).In layer interrupted suture method group,there were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing between median incision and rectus abdominis incision [33.33％ (23/69) vs.26.09％(6/23),66.67％ (46/69) vs.73.91％ (17/23),P ＞ 0.05].The rate of incision liquefaction and infection in median incision of full-thickness continuous suture method group was significantly lower than that in median incision of layer interrupted suture method group,and the rate of incision primary healing was significantly higher than that in median incision of layer interrupted suture method group,there were statistical differences (P ＜ 0.05).There were no statistical differences in the rate of incision liquefaction and infection,the rate of incision primary healing in rectus abdominis incision between the 2 groups (P ＞ 0.05).The bacterial culture result in patients with incision liquefaction and infection showed positive was in 26 cases,in full-thickness continuous suture method group was in 10 cases (6.90％,10/145),in layer interrupted suture method group was in 16 cases (17.39％,16/92),there was statistical difference (P ＜0.05).The mostly bacterial of infection was Escherichia coli.Conclusions The full-thickness continuous suture in median incision can shorten operative time and reduce the rate of incision liquefaction and infection in emergency abdominal operation.Suture technique has important impact on incision healing.
