Study on the Efficacy of U-shaped Multi-point Suture Fixing Skin Flap and Three-tube Negative Pressure Drainage Preventing Effusion After Modified Radical Mastectomy
Objective To investigate the efficacy of U-shaped multi-point suture fixing skin flap and three-tube neg-ative pressure drainage on preventing effusion after modified radical mastectomy type Ⅰ.Methods A total of 158 patients undergoing modified radical mastectomy type Ⅰ were selected as the study objects,and the patients were divided into ob-servation group(n=78)and control group(n=80)according to different types of skin flap suture,the observation group received U-shaped multi-point suture fixing skin flap and three-tube negative pressure drainage,while the control group received conventional suture and drainage method,the incidence of surgical complications,postoperative drainage volume,skin flap and axillary catheterization time and hospitalization time of patients between the two groups were compared.Results Postoperative subcutaneous effusion occurred in 8 cases(10.26％)in the observation group,which were 23 ca-ses(28.75％)lower than those in the control group,1 case(1.28％)of skin flap necrosis occurred in the observation group,which were 8 cases(10.00％)lower than those in the control group,and there was a statistically significant difference between the two groups(all P＜0.05).The drainage volume of the observation group was significantly lower than that of the control group 1-5 days after surgery(all P＜0.001).The time of skin flap catheterization,axillary cathe-terization and hospitalizationl time in the observation group were significantly shorter than those in the control group(all P＜0.001).Conclusion Compared with conventional suture and drainage method,U-shaped multi-point suture fixing skin flap and three-tube negative pressure drainage can effectively reduce the postoperative effusion drainage volume,low-er the incidence of subcutaneous effusion and skin flap necrosis,and shorten the duration of drainage tube placement and hospitalization time of the the patients.
