BACKGROUND: Microsurgery is a new technique for lymphedema treatment. Its advantages and disadvantages remain controversial. This study is sought to collect clinical data from patients who underwent lymphovenous bypass and vascularized lymph node transplantation to explore whether surgical procedures can effectively treat lymphedema.
METHODS: We performed a meta-analysis of the effectiveness of lymphatic microsurgery. We searched the databases of literature for articles in Chinese and English. These articles were graded for quality. Report details and outcomes were recorded. Data extraction, systematic review, and meta-analysis were performed.
RESULTS: Thirty-seven studies were included. Patients who underwent microsurgery had a significantly better chance of achieving an excellent result than patients who received conservative treatment (odds ratio = 7.07). The affected limb circumference was reduced by approximately, 44.68% after the microsurgery. After the microsurgery, 63% of the patients did not need physiotherapy, and 96% were free from painful skin infections. Lymphography showed that lymphatic transport capacity was enhanced. Moreover, 12% of the patients reported that edema reappeared in the long-term, 26% required reoperation for unsatisfactory results, and 32% experienced lymphatic leakage.
CONCLUSIONS: A vast majority of patients derive more benefit from lymphatic microsurgery than from conventional treatment. The advantages of lymphatic microsurgery outweigh the disadvantages for patients in the early and middle stages of chronic secondary lymphedema and patients in whom conventional treatment failed.
