IntroductionLymphedema can be a debilitating condition, causing a great decrease in a person’s quality of life (QoL). Treatment with lymphaticovenular anastomosis (LVA), in which an anastomosis is created between the lymphatic and venous system, may attenuate lymphedema symptoms and reduce swelling. In this study, we share the results using LVA to treat breast cancer-related lymphedema (BCRL) at our institution.Materials and methodsPatients were eligible for inclusion if they suffered from unilateral BCRL, if functional lymphatics were available, if compression therapy was used for at least 6 months, and if the follow-up was 12 months at minimum. Lymph vessel functionality was assessed preoperatively using indocyanine green (ICG). During surgery, 1–3 anastomoses were created and shunt patency was confirmed using ICG. Arm volumes were measured before surgery and at 6- and 12-month follow-up. QoL was measured before surgery and at 6-month follow-up. Arm volume differences between the healthy arm and affected arm were compared between the time points.ResultsTwenty-nine consecutive female patients with unilateral BCRL were included. The preoperative mean difference in arm volumes was 701 ± 435 ml (36.9%). This was reduced to 496 ± 302 ml (24.7%) at 6-month follow-up (p = 0.00). At 12-month follow-up, the mean difference in arm volume was 467 ± 303 ml (23.5%) (p = 0.02). The overall perceived QoL was increased from 5.8 ± 1.1 to 7.4 ± 0.7 (p = 0.00). The functionality score decreased from 2.2 to 1.8 (p = 0.00), the appearance score decreased from 2.6 to 1.9 (p = 0.00), the symptoms score decreased from 2.8 to 1.8 (p = 0.00), and the mood score decreased from 2.7 to 1.5 (p = 0.00). Fifteen patients (53.6%) were able to discontinue the use of compression garment.ConclusionTreatment with LVAs is effective in reducing arm volume difference in patients suffering from BCRL. Although no complete reduction of the edema was achieved at 12-month follow-up, the procedure significantly increased the patients’ QoL.

Background The component separation technique (CST) is considered an excellent technique for complex ventral hernia repair. However, postoperative infectious complications and reherniation rates are significant. Risk factor analysis for postoperative complication and reherniation has focused mostly on patient history and co-morbidity and shows equivocal results. The use of abdominal morphometrics derived from CT scans to assist in risk assessment seems promising. The aim of this study is to determine the predictability of reherniation and surgical site infections (SSI) using pre-operative CT measurements. Methods Electronic patient records were searched for patients who underwent CST between 2000 and 2013 and had a pre-operative CT scan available. Visceral fat volume (VFV), subcutaneous fat volume (SFV), loss of domain (LOD), rectus thickness and width (RT, RW), abdominal volume, hernia sac volume, total fat volume (TFV), sagittal distance (SD) and waist circumference (WC) were measured or calculated. Relevant variables were entered in multivariate regression analysis to determine their effect on reherniation and SSI as separate outcomes. Results Sixty-five patients were included. VFV ( p = 0.025, OR = 1.65) was a significant predictor regarding reherniation. Hernia sac volume ( p = 0.020, OR = 2.10) and SFV per 1000 cm 3 ( p = 0.034, OR = 0.26) were significant predictors of SSI. Conclusion Visceral fat volume, subcutaneous fat volume and hernia sac volume derived from CT scan measurements may be used to predict reherniation and SSI in patients undergoing complex ventral hernia repair using CST. These findings may aid in optimizing patient-tailored preoperative risk assessment.

Background and Objectives Lymphedema is a condition that can greatly affect patient's quality of life. Promising results have been described with lymphaticovenular anastomosis (LVA) in the treatment of lymphedema. It is currently unknown at what rate anastomoses remain functional after a longer follow-up. The aim of this study was to determine LVA patency at 1-year follow-up. Methods Retrospective chart review was performed on patients who underwent LVA surgery. Patients who had indocyanine green lymphography performed at 12 months' follow-up after LVA were included in this study. Volume measurements were performed prior to surgery and at 6 and 12 months' follow-up. Patients quality of life was measured prior to surgery and at 6 months' follow-up. Results Twelve patients met inclusion criteria. In total, 15 (56.5%) of 23 LVAs were considered patent. In 8 patients (66.7%), at least 1 patent LVA was visible. The volume difference between the healthy and affected arms decreased 32.3% on average. Quality of life increased with 1.4 points on average. Conclusions This study is, to our knowledge, the first to evaluate long-term patency of LVA in upper limb lymphedema. Our study demonstrates that at least 56.5% of the anastomoses created are patent after 1-year follow-up.

BackgroundFor several purposes, skin parameters like thickness and elasticity can be measured. However, little is known about the accuracy of those measurements.AimThe aim of this study was to determine the intrarater and test‐retest reliability of skin thickness and elasticity measurements performed with the DermaLab Combo®.MethodsA total of 49 participants were included in this study. Skin thickness and elasticity were measured at six defined locations on the dominant arm. Measurements were repeated two times by the same observer to determine the test‐retest reliability. To determine the inter‐rater reliability, a second observer repeated the measurements once.ResultsInter‐rater and test‐retest reliability for elasticity measurements fluctuates per location and per parameter: Inter‐rater intraclass correlation coefficient (ICC) ranged from 0.23 to 0.80, and test‐retest ICC ranged from 0.25 to 0.84. Skin thickness was measured reliable by every observer on every location, with a test‐retest ICC ranging from 0.71 to 0.83 and an inter‐rater ICC ranging from 0.69 to 0.80.ConclusionThe DermaLab Combo® showed a good inter‐rater reliability when measuring skin thickness and elasticity. Not all locations are suitable for reliable inter‐rater or test‐retest measurements. The device is difficult to use by inexperienced users, as the echo probe is sensitive to small movements.
