摘要

Abstract

Objective

Several options for the treatment of lower extremity lymphedema (LEL) can be broadly classified into conservative treatment, such as compression garments and decongestive lymphatic therapy, and surgical treatment, such as lymphaticovenular anastomosis (LVA). The purpose of our study was to clarify the superiority of these treatments by comparing the outcomes of LVA with those of conservative treatment for early-stage LEL.

Methods

We performed a single-center, retrospective cohort study. The patients with LEL who presented to our department between January 2015 and December 2022 were identified and classified into two groups: conservative treatment and surgical treatment. The LEL indexes, calculated from the four lower extremity circumferences and the body mass index, were compared at the 6-, 12-, and 24-month follow-up between the two groups.

Results

Of the 101 patients with LEL, 53 with 72 affected limbs (conservative treatment, 39 patients and 53 affected limbs; surgical treatment, 15 patients and 19 affected limbs) were included in the present analysis. The therapeutic effect for reducing edema, as determined by comparing the corrected LEL index at 12 months (103.7 ± 12.7 vs 91.9 ± 10.7; P = .005) and 24 months (103.1 ± 12.9 vs 83.8 ± 7.2; P < .001), was significantly higher in the surgical treatment group than that in the conservative treatment group. The conservative treatment group showed little change in the corrected LEL index at ≤24 months of follow-up (+3.1%; P = .299). In contrast, the surgical treatment group showed a significant reduction in edema at 24 months according to the corrected LEL index (−16.2%; P = .019).

Conclusions

In early-stage LEL, conservative treatment centered on compression therapy alone only maintained edema (ie, edema did not worsen or improve). In contrast, LVA with compression therapy reduced edema.
