Abstract: Objective To investigate the effect of Mammotome minimally invasive excision with drainage on postoperative pain,inflammatory stress indexes and complications in patients with benign breast tumors．Methods A total of 100 patients with benign breast tumors admitted to our hospital from January 2020 to January 2022 were selected and grouped by simple random method,each patient was assigned a random number．Patients No.1 to No.51 were included in the experimental group,treated with Mammotome minimally invasive excision with drainage．Patients No.52 to No.100 were included in the control group,treated with Mammotome minimally invasive excision．The treatment effect,perioperative indicators,pain level（NRS score）and inflammatory stress indexes before and 1st and 3rd days after operation and complications were compared between the two groups．Results There were no significant differences in the lesion clearance rate（100.00% vs 97.96%）and the complication rate（3.92% vs 16.32%）between the two groups（P>0.05）．Compared with the control group,the experimental group had longer operation time,less residual cavity liquid and shorter hospital stay（P<0.05）．The NRS score of the experimental group was lower than that of the control group at 1st and 3rd days after operation（P<0.05）．On the third day after operation,the levels of C-reactive protein,interleukin- 6,interleukin-1β and procalcitonin in the two groups were increased compared with those before operation,and the increase in the experimental group was smaller than that in the observation group（P<0.05）．Conclusions Mammotome minimally invasive excision with drainage in the treatment of benign breast tumors can reduce residual cavity fluid accumulation,reduce the degree of inflammatory response,help postoperative incision healing,relieve postoperative pain,and without increasing the risk of complications．
