Long term outcomes from lymphatic venous anastomosis after total hysterectomy to prevent postoperative lymphedema in lower limb

Primary Lymphovenous Anastomosis After Extended Soft Tissue Resection in the Medial Thigh for Reduction of Lymphocele and Lymphedema

INTRODUCTION

Postoperative chronic lymphocele and lymphedema represent severe burdens for soft tissue sarcoma patients who are already physically handicapped after an extensive surgery and a long recovery time. Incidences are high in the upper medial thigh. We have shifted our focus to lymphedema and lymphocele risk reduction with immediate lymphovenous anastomosis (LVA) after sarcoma resection.

METHODS

We performed immediate lymphatic reconstruction in 11 patients after soft tissue sarcoma resection in the upper medial thigh. The postoperative course was followed up closely, and postoperative occurrence of lymphocele and lymphedema was clinically assessed. A literature search outlining the latest clinical data, current treatment strategy landscape, and their application into clinical practice was added to the investigation.

RESULTS

A total of 19 LVA and 2 lympho-lymphatic anastomoses were performed in 11 patients immediately after tumor resection in an end-to-end manner. We found a postoperative lymphedema rate of 36% and a postoperative lymphocele rate of 27%. Mean follow-up time was 17 months. Average tumor volume was 749 cc. Our literature search yielded 27 articles reporting on immediate LVA in cancer patients. Incidences of secondary lymphedema after LVA for lymphedema prevention vary between 0% and 31.1%. Lymphocele prevention with LVA is poorly studied in sarcoma patients.

CONCLUSION

Immediate lymphatic reconstruction improved the overall postoperative course of our patients. The current literature does not serve with high-quality studies about primary LVA preventing lymphedema and lymphocele formation. We conclude that this technique should be seen as an additional concept to achieve overall better postoperative outcomes in these challenging surgical settings. We strongly recommend to either anastomose or ligate severed lymphatics under the microscope primarily after sarcoma resection in the upper medial thigh area.

Primary surgical prevention of lymphedema

Lymphedema in the upper and lower extremities can lead to significant morbidity in patients, resulting in restricted joint movements, pain, discomfort, and reduced quality of life. While physiological lymphatic reconstructions such as lymphovenous anastomosis (LVA), lymphovenous implantation (LVI), and vascularized lymph node transfer (VLNT) have shown promise in improving patients' conditions, they only provide limited disease progression control or modest reversal. As lymphedema remains an incurable condition, the focus has shifted toward preventive measures in developed countries where most cases are iatrogenic due to cancer treatments. Breast cancer-related lymphedema (BCRL) has been a particular concern, prompting the implementation of preventive measures like axillary reverse mapping. Similarly, techniques with lymph node-preserving concepts have been used to treat lower extremity lymphedema caused by gynecological cancers. Preventive lymphedema measures can be classified into primary, secondary, and tertiary prevention. In this comprehensive review, we will explore the principles and methodologies encompassing lymphatic microsurgical preventive healing approach (LYMPHA), LVA, lymphaticolymphatic anastomosis (LLA), VLNT, and lymph-interpositional-flap transfer (LIFT). By evaluating the advantages and limitations of these techniques, we aim to equip surgeons with the necessary knowledge to effectively address patients at high risk of developing lymphedema.

Immediate-delayed lymphatic reconstruction after axillary lymph nodes dissection for locally advanced breast cancer-related lymphedema prevention: Report of two cases

Approximately 60%-70% of breast cancer patients in Indonesia are diagnosed in the locally advanced stage. The stage carries a higher risk of lymph node metastasis which increases susceptibility to lymph obstruction. Hence, breast cancer-related lymphedema (BCRL) could present before axillary lymph node dissection (ALND). The purpose of this case report is to describe immediate-delayed lymphatic reconstructions with lymphaticovenous anastomosis in two subclinical lymphedema cases that present before ALND. There were 51 and 58 years old breast cancer patients with stage IIIC and IIIB, respectively. Both had no arm lymphedema symptoms, but arm lymphatic vessel abnormalities were found during preoperative indocyanine green (ICG) lymphography. Mastectomy and ALND were performed and proceeded with lymphaticovenous anastomoses (LVA) in both cases. One LVA at the axilla (isotopic) was done in the first patient. On the second patient, 3 LVAs at the affected arm (ectopic) and 3 isotopic LVAs were created. The patients were discharged on the second day without complications during the follow-up. The intensity of dermal backflow was reduced, and no subclinical lymphedema progression occurred during 11 and 9 months follow-up, respectively. Based on these cases, BCRL screening might be recommended for the locally advanced stage before cancer treatment. Once diagnosed, immediate lymphatic reconstruction after ALND should be recommended to cure or prevent BCRL progression.

Immediate inguinal lymphaticovenous anastomosis following lymphadenectomy in skin cancer of lower extremities

BACKGROUND

Secondary lymphedema following inguinal lymph node dissection in lower extremities skin cancer reduce the patients' quality of life. Immediate lymphaticovenous anastomosis (LVA) at groin is a procedure intended to prevent secondary lymphedema. The data regarding the long-term efficacy and safety of this procedure was limited. Therefore, we evaluated the long-term outcomes of immediate LVA in patients with melanoma and non-melanoma skin cancer of the lower extremities.

METHODS

The retrospective data review of patients with melanoma or squamous cell carcinoma of the lower extremities underwent oncologic tumor resection with groin node dissection between December 2013 and December 2016 was performed. Seven patients underwent immediate LVA (intervention) at groin after node dissection and 22 acted as controls. The occurrence of lymphedema and oncologic outcomes were followed up to 7 years.

RESULTS

Fifteen patients (51.7%) developed postoperative lymphedema, which were three patients in the intervention group and twelve patients in the control group (p = 0.68). The intervention group had significant lower 2-year (57.1% versus 77.3%) and 5-year overall survival (14.3% versus 54.5%) (p = 0.035). The intervention group had reduced 2-year (28.6% versus 86.4%) and 5-year (28.6% versus 68.2%) Recurrence Free Survival (RFS) (p = 0.013). The intervention group also had reduced 2-year (0% versus 90%) and 5-year (0% versus 70%) Metastasis Free Survival (MFS) (p = 0.003).

CONCLUSION

Immediate inguinal LVA following groin node dissection in lower extremity skin cancer patients did not reduce the incidence of lymphedema. Unfortunately, it was associated with lower overall survival and an increase in tumor recurrence and metastasis.

Primary Prevention of Cancer-Related Lymphedema Using Preventive Lymphatic Surgery: Systematic Review and Meta-analysis

Background  Several studies have proven prophylactic lymphovenous anastomosis (LVA) performed after lymphadenectomy can potentially reduce the risk of cancer-related lymphedema (CRL) without compromising the oncological treatment. We present a systematic review of the current evidence on the primary prevention of CRL using preventive lymphatic surgery (PLS). Patients and Methods  A comprehensive search across PubMed, Cochrane-EBMR, Web of Science, Ovid Medline (R) and in-process, SCOPUS, and ScienceDirect was performed through December 2020. A meta-analysis with a random-effect method was accomplished. Results  Twenty-four studies including 1547 patients fulfilled the inclusion criteria. Overall, 830 prophylactic LVA procedures were performed after oncological treatment, of which 61 developed lymphedema. The pooled cumulative rate of upper extremity lymphedema after axillary lymph node dissection (ALND) and PLS was 5.15% (95% CI, 2.9%-7.5%; p  < 0.01). The pooled cumulative rate of lower extremity lymphedema after oncological surgical treatment and PLS was 6.66% (95% CI < 1-13.4%, p-value = 0.5). Pooled analysis showed that PLS reduced the incidence of upper and lower limb lymphedema after lymph node dissection by 18.7 per 100 patients treated (risk difference [RD] - 18.7%, 95% CI - 29.5% to - 7.9%; p  < 0.001) and by 30.3 per 100 patients treated (RD - 30.3%, 95% CI - 46.5% to - 14%; p  < 0.001), respectively, versus no prophylactic lymphatic reconstruction. Conclusions  Low-quality studies and a high risk of bias halt the formulating of strong recommendations in favor of PLS, despite preliminary reports theoretically indicating that the inclusion of PLS may significantly decrease the incidence of CRL.

Risk factors of recurrent erysipelas in adult Chinese patients: a prospective cohort study

BACKGROUND

Erysipelas is a common skin infection that is prone to recur. Recurrent erysipelas has a severe effect on the quality of life of patients. The present study aimed to investigate the risk factors of recurrent erysipelas in adult Chinese patients.

METHODS

A total of 428 Chinese patients with erysipelas who met the inclusion criteria were studied. The patients were divided into the nonrecurrent erysipelas group and the recurrent erysipelas group. Clinical data were collected on the first episode and relapse of erysipelas. The patients were followed up every 3 months. Statistical analysis was performed to analyze and determine the risk factors of erysipelas relapse.

RESULTS

Univariate analysis was performed to analyze the data, including surgery, types of antibiotics administered in the first episode, obesity, diabetes mellitus, venous insufficiency, lymphedema, and malignancy. The differences between the groups were statistically significant (p < 0.05). The Cox proportional hazards regression model analysis showed that the final risk factors included surgery, obesity, diabetes mellitus, venous insufficiency, and lymphedema.

CONCLUSIONS

Surgery, obesity, diabetes mellitus, venous insufficiency, and lymphedema are considered as risk factors for recurrent erysipelas.

Treatment and Impact of Cervical-Cancer-Related Lymphatic Disorders on Quality of Life and Sexuality Compared with Controls

Background: Lymphatic disorders are frequent complications related to treatment for cervical cancer (CC). The aims of the study are to evaluate the impact of lymphatic disorders on quality of life (QOL) and sexuality in CC survivors after the completion of oncological treatment and to compare them with controls. Methods and Results: An ambispective cohort study was performed by using the Functional Assessment Cancer Therapy (FACT)-Cervix (Cx) fourth version, the World Health Organization Quality of Life-Brief Version (WHOQOL-BREF), and the Female Sexual Function Index (FSFI). Twelve patients affected by lymphatic disorders comprised the study group, 251 comprised the CC control group, and 185 comprised the non-CC control group. Regarding QOL, there were no statistically significant differences between the lymphatic disorder-unaffected and non-CC control groups, except in the WHOQOL-BREF environment domain. A weak positive correlation between lymphatic disorder and FACT-Cx additional concerns (σ = 0.135) was observed. Regarding sexuality, a weak negative correlation was detected between lymphatic disorders and FSFI sexual satisfaction (σ = -0.200) and a weak positive correlation was observed between lymphatic disorders and FSFI dyspareunia (σ = 0.148). We did not observe statistically significant differences in QOL satisfaction between the lymphatic disorder-affected and non-CC control groups. Symptomatic controls reported significantly higher physical health scores than the lymphatic disorder-affected group (p < 0.05). Regarding the psychological domain, the asymptomatic controls obtained significantly higher scores than the lymphatic disorder-affected group (p = 0.003). Conclusions: Lymphatic disorders notably influenced the QOL of CC survivors compared with the non-CC control groups. Lymphatic disorders had a significant negative impact on physical and psychological health. Sexuality was scarcely affected by lymphatic disorders.
