Abstract:

Objective To explore the effect of suction volume reduction surgery in the treatment of upper limb lymphedema

after breast cancer surgery with different severity. Methods The clinical data of 42 patients with upper limb lymphedema

after breast cancer surgery from January 2020 to December 2022 were retrospectively analyzed， including 42 women aged

（57.19±8.79） years. According to the severity， the patients were divided into non-severe group （n=25） and severe group （n=17）

.

The clinical characteristics of patients with upper limb lymphedema after breast cancer surgery of different severity were

analyzed， and the application effect of suction volume reduction surgery on upper limb lymphedema after breast cancer

surgery of different severity was analyzed. Results The average age of the non-severe group was （54.6±8.85） years old，

while the average age of the severe group was （61.0±7.39） years old， with a statistically significant difference （P=0.019）

.

The preoperative BMI of the non-severe group was （26.58±3.64） kg/m2 ， while the BMI of the severe group was （29.11±5.83）

kg/m2 ， with no statistically significant difference between the two groups （P=0.091）

. In terms of operation mode，

lymphedema aspiration was performed for patients with non-severe/severe upper limb lymphedema after operation of breast

cancer， while a few patients with extremely severe upper limb lymphedema were treated with lymphedema aspiration

combined with pathological tissue resection. Compared with the severe group， the surgery time， injection volume of swelling

fluid， suction volume of fat suspension， liposuction volume， and intraoperative bleeding volume in the non-severe group had

statistical differences （P<0.01）

. The swelling degree of the two groups was improved after operation and 3 months after

operation （P<0.01）， and the swelling improvement degree of the non-severe group was significantly better than that of the

severe group after operation and 3 months after operation， the difference was statistically significant （P<0.01）

. Conclusion 

Aspiration volume reduction surgery can significantly improve the degree of limb swelling of upper limb lymphedema after

breast cancer surgery of different severity.
