Comparison the efficacy of minimally invasive surgery and traditional surgery in the treatment of multiple benign mammary lumps

Abstract

Objective To compare the clinical efficacy of minimally invasive surgery and traditional surgery in the treatment of multiple benign mammary lumps. Methods A retrospective study was conducted to select 158 patients with multiple benign breast masses admitted to Yijishan Hospital of Wannan Medical College from July 2016 to February 2018, all of them were female, average age was (28.3±6.6) years old, range from 19 to 51 years old. The patients were divided into minimally invasive group (n=122) and traditional group (n=36) according to different surgical methods. The minimally invasive group was treated by minimally invasive rotary excision, while the traditional group was treated by traditional surgery. The operation time, number of incisions, average length of incisions, cumulative length of incisions and healing time of incisions were compared between the two groups. The incidence of local hematoma, local infection, breast deformity and local residual were compared after operation, and the satisfaction of the two groups was aslo compared. Normal distribution measurements were expressed by mean±standard deviation (Mean±SD), independent sample t test was used for inter-group comparison; non-normal distribution measurements were expressed by median (quartile spacing) [M(P25, P75)], Mann-Whitney U test was used for inter-group comparison. Chi-square test or Fisher exact probability test was used to compare the count data between the two groups. Results As compared to the traditional group, the minimally invasive group had shorter operation time (20.0 min vs 40.0 min, Z=-8.590, P<0.001), less number of incisions (1.0 vs 2.0, Z=-4.423, P<0.001), smaller average surgical incision length (3.8 mm vs 35.5 mm, Z=-9.211, P<0.001), smaller cumulative surgical incision length (4.0 mm vs 67.2 mm, Z=-9.130, P<0.001), quicker postoperative recovery (4.0 d vs 7.0 d, Z=-9.334, P<0.001). There were no significant differences between the two groups in incidence of postoperative hematoma (4.1% vs 2.8%, χ2=0. 000, P=1.000), incidence of infection (0 vs 2.8%, P=0.228), incidence of postoperative breast shape change (1.6% vs 2.8%, χ2=0.000, P=1.000), and incidence of residual (0.8% vs 0, P=1.000). Psychological satisfaction of patients in minimally invasive group (95.1%) was significantly higher than that in traditional group (58.3%), the difference was statistically significant (P<0.001). Conclusions Compared with traditional surgery, the application of minimally invasive surgery in the treatment of multiple benign mammary lumps has many advantages, such as shorter operation time, less number of incisions, smaller surgical incision length, quicker postoperative recovery and higher satisfaction of patients after operation. It has not significantly increased postoperative complications. It is worthy of clinical application and promotion.
