Effects of sentinel lymph node biopsy utilization on operative time, intraoperative blood loss and extubation time / 中国基层医药

ABSTRACT

Objective:To investigate the effects of sentinel lymph node biopsy utilization on operative time, intraoperative blood loss and extubation time.Methods:Sixty-two patients with breast cancer who received treatment in the First Hospital of China Medical University from January to December 2019 were included in this study. They were randomly assigned to receive either conventional breast cancer surgery (control group, n = 31) or sentinel lymph node biopsy combined with breast cancer surgery (study group, n = 31). Extubation time, operative time, intraoperative blood loss, drainage volume, breast cosmetic effect, upper limb function and complications were compared between the two groups. Results:Extubation time and operative time in the study group were (16.3 ± 1.1) hours and (61.6 ± 11.3) minutes, respectively, and they were (28.2 ± 6.4) hours and (124.2 ± 28.5) minutes, respectively in the control group. There were significant differences in extubation time and operative time between the two groups ( t = 14.922 and 16.479, both P < 0.05). Intraoperative blood loss and postoperative drainage volume in the study group were (68.7 ± 17.9) mL and (105.9 ± 19.5) mL respectively, and they were (122.4 ± 23.1) mL and (257.2 ± 36.4) mL respectively in the control group. There were significant different differences in intraoperative blood loss and postoperative drainage volume between the two groups ( t = 15.928 and 18.797, both P < 0.05). The excellent and good rate of breast cosmetic effect in the study group was significantly higher than that in the control group (93.6% vs. 83.8% , χ2 = 5.584, P < 0.05). After treatment, the difference in the upper arm circumference between the healthy and affected sides, and shoulder abduction and shoulder function score in the study group were (0.5 ± 0.1) cm, (123.7 ± 6.6) ° and (75.9 ± 4.9) points respectively, and they were (0.7 ± 0.1) cm, (120.1 ± 6.1) °, (73.5 ± 4.4) points, respectively in the control group. There were significant differences in these indices between the two groups ( t = 11.432, 12.450, 12.647, all P < 0.05). The incidence of complications in the study group was significantly lower than that in the control group (12.9% vs. 38.8%, χ2 = 6.309, P < 0.05). Conclusion:Sentinel lymph node biopsy can help improve therapeutic effects, shorten the operative time, reduce the amount of intraoperative bleeding, shorten the extubation time, and reduce the incidence of complications in breast cancer patients.
