RESUMO

BACKGROUND: Seroma is the most common complication following breast cancer surgery, with reported incidence up to 90%. Seroma causes patient discomfort, is associated with surgical site infections (SSI), often requires treatment and increases healthcare consumption. The quilting suture technique, in which the skin flaps are sutured to the pectoralis muscle, leads to a significant reduction of seroma with a decrease in the number of aspirations and surgical site infections. However, implementation is lagging due to unknown side effects, increase in operation time and cost effectiveness. Main objective of this study is to assess the impact of large scale implementation of the quilting suture technique in patients undergoing mastectomy and/or axillary lymph node dissection (ALND). METHODS: The QUILT study is a stepped wedge design study performed among nine teaching hospitals in the Netherlands. The study consists of nine steps, with each step one hospital will implement the quilting suture technique. Allocation of the order of implementation will be randomization-based. Primary outcome is 'textbook outcome', i.e.no wound complications, no re-admission, re-operation or unscheduled visit to the outpatient clinic and no increased use of postoperative analgesics. A total of 113 patients is required based on a sample size calculation. Secondary outcomes are shoulder function, cosmetic outcome, satisfaction with thoracic wall and health care consumption. Follow-up lasts for 6 months. DISCUSSION: This will be one of the first multicentre prospective studies in which quilting without postoperative wound drain is compared with conventional wound closure. We hypothesize that quilting is a simple technique to increase textbook outcome, enhance patient comfort and reduce health care consumption.

RESUMO

Objective: Radiofrequency ablation (RFA) is increasingly considered the prime option for treating symptomatic, benign, non-functioning thyroid nodules (NFTN). However, little is known about the degree of operator experience required to achieve optimal results. This study describes the RFA learning curve of a single-center team. Methods: A retrospective cohort study of the first 103 patients receiving RFA treatment for a single, symptomatic, and benign NFTN, with a follow-up of at least 1 year. The primary outcome measure was technique efficacy, defined as the percentage of patients with a 6-month nodal volume reduction ratio (VRR) >50% after single-session RFA. Optimal treatment efficacy was defined as a 6-month VRR >50% achieved in at least 75% of patients. Secondary outcomes were complications of RFA and indications of secondary interventions. Results: Median nodal volume at baseline was 12.0 mL (range 2.0-58.0 mL). A 6-month VRR >50% was achieved in 45% of the first 20 patients, 75% of the next 20, and 79% of the following 63 patients. Complications included minor bleeding (N = 4), transient hyperthyroidism (N = 4), and transient loss of voice (N = 1). Poor volume reduction or nodular regrowth led to diagnostic lobectomy in 11 patients and a second RFA in 5. Lobectomy revealed a follicular carcinoma (T2N0M0) in 2 patients. In 1 patient, nodule regrowth was caused by an intranodular solitary B-cell lymphoma. Conclusion: About 40 procedures are required to achieve a 6-month VRR >50% in the majority of patients. Appropriate follow-up with re-evaluation is recommended for all patients with a VRR <50% and in those with regrowth to exclude underlying malignancy.

RESUMO

BACKGROUND: Taking patient centeredness into account is important in healthcare. The European Cancer Consumer Quality Index (ECCQI) is a validated tool for international benchmarking of patient experiences and satisfaction. This study aimed to further validate the ECCQI in larger and more uniform groups of high volume tumours such as breast and prostate cancer. A second objective was the verification of the influence of cultural factors of the country to determine its possible use in international benchmarking. METHODS: Data from two survey studies in eight European countries were combined. Socio-demographic correlations were analysed with Kruskall-Wallis and Mann-Whitney tests. Cronbach's alpha was calculated to validate internal consistency. Influences of masculinity (MAS), power distance (PD) and uncertainty avoidance (UA) were determined by linear regression analysis in a general model and subgroup models. RESULTS: A total of 1322 surveys were included in the analysis (1093 breast- and 348 prostate cancer patients). Cronbach's alpha was good (α ≥ 0.7) or acceptable (0.5 ≤ α ≤ 0.7) in 8 out of 9 questionnaire categories, except in the category 'Safety' (α = 0.305). Overall ECCQI scores ranged from 22.1 to 25.1 between countries on a 1-35 scale (categories had a 1-4 scale). In certain subcategories such as 'Organisation' (range 2.2 vs 3.0) and 'Supervision & Support' (range 3.0 vs 3.8) a large difference was observed between countries. Differences in 'Overall opinion' were however small: mean scores of 3.7 vs 3.9, whereas median scores were all the maximum of 4.0. Power distance was positively associated with higher patient satisfaction scores whereas Uncertainty avoidance was negatively associated with these scores. Masculinity was only associated with patient satisfaction scores in lower educated patients. We found the highest impact of culture on overall scores in Hungary and Portugal and the lowest in Romania. CONCLUSIONS: The ECCQI shows high internal consistency in all categories except 'Safety'. Especially in separate categories and overall ECCQI scores the questionnaire showed discriminative value. This study showed a positive correlation of power distance and a negative correlation for uncertainty avoidance in some countries. When using the ECCQI for international benchmarking these two dimensions of culture should be taken into account.

RESUMO

OBJECTIVE/BACKGROUND: Mechanochemical endovenous ablation (MOCA) has been developed as a tumescentless technique to ablate saphenous veins and to avoid heat induced complications and post-procedural pain. The mechanism of action of MOCA is poorly understood. The present experiments were conducted to determine the effect of MOCA on vein wall injury and sclerosis in an animal model. METHODS: A total of 36 lateral saphenous veins (LSVs) were treated in 18 goats according to the human protocol. Veins from nine goats were evaluated 45 min after the procedure, while in the remaining nine, the treated veins were evaluated 6 weeks later. All treated veins were divided equally over three treatment groups: (i) MOCA, (ii) mechanical ablation without the sclerosant, and (iii) liquid sclerotherapy alone. The histological effects of treatment on the vein wall were systematically evaluated. RESULTS: The average diameter of the LSV was 4.0 ± 0.5 mm. Technical success was achieved in all but one LSV (35/36; 97%), with a median procedure time of 14 min (range 9-22 min). In the acute group, histological examination showed that mechanical ablation (alone or MOCA) induced severe injury to the endothelium in 82% but no damage to other layers of the vein wall. Mechanical ablation led to vasoconstriction. After 6 weeks follow-up, four of six MOCA treated veins were occluded. The occluded segments consisted mainly of fibrotic lesions probably evolved from organised thrombus. No occlusions were observed after sclerotherapy or mechanical treatment alone. No major complications occurred during procedures or follow-up. CONCLUSION: MOCA is associated with an increased occlusion rate compared with its separated components of mechanical ablation or sclerotherapy. The occlusion consists of cellular fibrotic material likely to be evolved from organised thrombus with fibrotic alterations to the surrounding media and adventitia. This study underlines the hypothesis that the additive use of MOCA increases the effectiveness of sclerosants alone by inducing endothelial damage and probably vasoconstriction.

RESUMO

OBJECTIVE: This study evaluated the feasibility, safety and 1-year results of mechanochemical endovenous ablation (MOCA™) of small saphenous vein (SSV) insufficiency. DESIGN: Prospective cohort study. MATERIALS AND METHODS: Fifty consecutive patients were treated for primary SSV insufficiency with MOCA™ using the ClariVein(®) device and polidocanol. Initial technical success, complications, patient satisfaction and visual analogue scale (VAS) pain score were assessed. Anatomic and clinical success was assessed at 6 weeks and at 1 year. RESULTS: Initial technical success of MOCA™ was 100%. At the 6-week assessment, all treated veins were occluded. The 1-year follow-up duplex showed anatomic success in 94% (95% confidence interval, 0.87-1). Venous clinical severity score (VCSS) decreased significantly from 3.0 (interquartile range (IQR) 2-5) before treatment to 1.0 (IQR 1-3, P < 0.001) at 6 weeks and to 1.0 (IQR 1-2, P < 0.001) at 1 year. Median procedural VAS score for pain was 2 (IQR 2-4). No major complications were observed, especially no nerve injury. CONCLUSIONS: MOCA™ is a safe, feasible and efficacious technique for treatment of SSV insufficiency. One-year follow-up shows a 94% anatomic success rate and no major complications.
