Tackling obesity as part of a lymphoedema management programme

Impact of body mass index on long-term surgical outcomes of vascularized lymph node transfer in lymphedema patients

Background

Vascularized lymph node transfer (VLNT) is a surgical procedure with high interest to treat lymphedema. Body mass index (BMI) is a well-described factor that increases the risk of lymphedema, but little is known about its influence on the surgical outcomes of lymphedema patients who undergo VLNT. The aim of this study was to analyze the impact of preoperative BMI on the long-term surgical outcomes after VLNT in lymphedema patients.

Methods

We retrospectively compiled data of patients with International Society of Lymphology (ISL) stage II or III lymphedema who were treated with VLNT from July 2010 to July 2016 at China Medical University Hospital. Preoperative and postoperative demographic and clinical data, such as limb circumference and number of infection episodes were reviewed. Statistical analyses compared circumference reduction rates and infection episode reduction between preoperative BMI categories was done. In addition, prediction of outcomes based on quantitative preoperative BMI was analyzed.

Results

A total of 83 patients met the inclusion criteria. Nine patients (10.8%) were normal weight, 43 (51.8%) were overweight, and 31 (37.3%) were obese. Compared with normal-weight patients, mean circumference reduction rates were significantly lower in overweight (P=0.005) and obese patients (P=0.02), but quantitative BMI was not correlated with circumference reduction rate (P=0.96). However, obese patients had a significantly greater reduction in infection episodes than normal-weight patients (P=0.03). In addition, greater BMI predicted greater reduction in infection episodes after VLNT (P=0.02).

Conclusions

VLNT is an effective surgical treatment, especially for lymphedema patients with higher preoperative BMIs. The results of our study suggest that this procedure considerably decreases the number of postoperative infection episodes per year in obese patients, even though preoperative BMI does not influence circumference reduction rate.

Treating patients with venous leg ulcers in the acute setting: part 1

Leg ulcers present with a variety of aetiologies, sometimes in combination. The most common aetiology is venous, with treament involving compression, elevation and exercise; the most common treatment setting is the community. However, people with leg ulcers do sometimes require admission to hospital for conditions and situations which may, or may not, be ulcer-related. There is a lack of contemporary evidence on the experience of inpatients and insufficient analysis of the impact on healing and complications to the lower limb when patients with leg ulcers and compression therapy are admitted to hospital. Admission to hospital presents an ideal opportunity for a focus on leg care and potentially enhancing healing rates of patients. The reality for patients with venous leg ulceration being treated with compression therapy is that this does not continue if they are admitted to hospital as inpatients-having been interrupted for MRSA screening and skin assessment, often no-one is available to reinstate the therapy. This article highlights key issues in the ongoing care of these patients and offers suggestions for basic management until a more acceptable and evidence-based solution can be found. Part 2 will deal with the preparation for discharge and options for the treatment of patients who are not already in the care of community services.

Lower-limb oedema: assessment, treatment and challenges

The incidence and prevalence of lymphoedema and chronic oedema is increasing as a result of the ageing population and increased obesity rates. It is becoming increasingly common for long-term conditions to be managed in the community, and community nurses are highly likely to be involved in identifying and providing care for patients affected by lower-limb oedema. Oedema is frequently recognised but often not treated, and practitioners must remember that oedema is a symptom and the underlying cause needs to be established to ensure that appropriate treatment can be initiated. Many community nurses regularly see the same patients with chronic oedema for months, and even years. This article is designed to promote reflection on whether current treatment regimes are proving effective.

The management of a patient with chronic oedema: a case study

Chronic oedema is a complex long-term condition that can have profound effects on the patient. Therefore, it is vital that the district nurse has the knowledge and skills to manage an individual to ensure a therapeutic concordant relationship. This feature seeks to consider best-practice management of a patient with chronic oedema.
