The treatment of patients with diabetic foot ulcers (DFUs) is extremely complex, requiring a comprehensive approach that involves a variety of different healthcare professionals. Several studies have shown that a multidisciplinary team (MDT) approach is useful to achieve good clinical outcomes, reducing major and minor amputation and increasing the chance of healing. Despite this, the multidisciplinary approach is not always a recognized treatment strategy. The aim of this meta-analysis was to assess the effects of an MDT approach on major adverse limb events, healing, time-to-heal, all-cause mortality, and other clinical outcomes in patients with active DFUs. The present meta-analysis was performed for the purpose of developing Italian guidelines for the treatment of diabetic foot with the support of the Italian Society of Diabetology (Società Italiana di Diabetologia, SID) and the Italian Association of Clinical Diabetologists (Associazione Medici Diabetologi, AMD). The study was performed using the Grading of Recommendations Assessment, Development, and Evaluation approach. All randomized clinical trials and observational studies, with a duration of at least 26 weeks, which compared the MDT approach with any other organizational strategy in the management of patients with DFUs were considered. Animal studies were excluded. A search of Medline and Embase databases was performed up until the May 1st, 2023. Patients managed by an MDT were reported to have better outcomes in terms of healing, minor and major amputation, and survival in comparison with those managed using other approaches. No data were found on quality of life, returning-to-walking, and emergency admission. Authors concluded that the MDT may be effective in improving outcomes in patients with DFUs.

The arterial lesions in the lower limbs of diabetic foot patients are very complex, and restoring arterial blood flow in the lower limbs is the key to improving the quality of life and limb preservation rate of diabetic foot patients. The current endovascular treatment technique is the main choice in China because of its minimally invasive nature and rapid postoperative recovery. In order to provide better and more standardized treatment for diabetic foot and benefit patients, the Diabetic Foot Sub-Committee of the China Association for the Promotion of International Exchange of Healthcare and the Diabetic Foot Committee of the Chinese Chapter Congress of the International Union of Angiology have developed this consensus based on the literature and the clinical experience of various experts, including the objectives and principles of diabetic foot treatment and the selection of endovascular treatment methods for vascular lesions.

Optimal management of sarcoma requires multidisciplinary team input throughout the process of diagnosis, treatment and follow up. This systematic review aimed to evaluate the impact of surgery performed at specialised sarcoma centres on outcomes.
A systematic review was conducted using the population, intervention, comparison and outcome (PICO) model. Medline, Embase, Cochrane Central databases were queried for publications that evaluated the local control, limb salvage rate, 30-day and 90-day surgical mortality, and overall survival in patients undergoing surgery in a specialist sarcoma centre compared with non-specialist centre. Each study was screened by two independent reviewers for suitability. A qualitative synthesis of the results was performed.
Sixty-six studies were identified. The majority of studies were Level III-3 as assessed by the NHMRC Evidence Hierarchy, whilst just over half of the studies were of good quality. Definitive surgery performed at specialised sarcoma centres was associated with improved local control as defined by lower rate of local relapse, higher rate of negative surgical margins, improved local recurrence free survival and higher limb conservation rate. Available evidences show a favourable pattern of lower 30-day and 90-day mortality rates, and greater overall survival when surgery was performed in specialist sarcoma centres compared with non-specialised centres.
Evidences support better oncological outcomes when surgery is performed at specialised sarcoma centre. Patients with suspected sarcoma should be referred early to a specialised sarcoma centre for multidisciplinary management, which includes planned biopsy and definitive surgery.

The aim of this study was to examine outcomes between bypass surgery and endovascular therapy (EVT) in patients with chronic limb-threatening ischemia (CLTI), classified as bypass-preferred according to the Global Vascular Guidelines (GVG).
We retrospectively analyzed the multi-center data of patients who underwent infrainguinal revascularization for CLTI with Wound, Ischemia, and foot Infection (WIfI) Stage 3 to 4 and Global Limb Anatomical Staging System (GLASS) Stage III, which is classified as bypass-preferred category by the GVG between 2015 and 2020. The endpoints were limb salvage and wound healing.
We analyzed 301 patients and 339 limbs following 156 bypass surgeries and 183 EVTs. The 2-year limb salvage rates were 92.2% in the bypass surgery group and 76.3% in the EVT group, respectively (P < .01). The 1-year wound healing rates were 86.7% in the bypass surgery group and 67.8% in the EVT group (P < .01). Multivariate analysis shows decreased serum albumin level (P < .01), increased wound grade (P = .04), and EVT (P < .01) were risk factors for major amputation. Decreased serum albumin level (P < .01), increased wound grade (P < .01), GLASS infrapopliteal grade (P = .02), inframalleolar (IM) P grade (P = .01), and EVT (P < .01) were risk factors for impaired wound healing. Subgroup analysis of limb salvage in patients after EVT, decreased serum albumin level (P < .01), increased wound grade (P = .03), increased IM P grade (P = .04), and congestive heart failure (P < .01) were risk factors for major amputation. According to scoring by existence of these risk factors, 2-year limb salvage rates following EVT were 83.0% and 42.8% for the total score of 0 to 2 and of 3 to 4, respectively (P < .01).
Bypass surgery provides better limb salvage and wound healing in patients with WIfI Stage 3 to 4 and GLASS Stage III, which is classified as bypass-preferred category by the GVG. In patients after EVT, serum albumin level, wound grade, IM P grade, and congestive heart failure were related to major amputation. Although bypass surgery may be considered as initial revascularization procedure in patients classified as bypass-preferred category, in case that EVT has to be selected, relatively acceptable outcomes can be expected in patients with less of these risk factors.

BACKGROUND: The Global Vascular Guidelines (GVG) recommend selecting an endovascular versus open-surgical approach to revascularization for chronic limb-threatening ischemia (CLTI), based on the Global Limb Anatomic Staging System (GLASS) and wound, ischemia, and foot infection (WIfI) classification systems. We assessed the utility of GVG-recommended strategies in predicting clinical outcomes.
METHODS: We conducted a single-center, retrospective review of first-time lower-extremity revascularizations within a comprehensive limb-preservation program from 2010 to 2018. Procedures were stratified by (1) treatment concordance with GVG-recommended strategy (concordant versus nonconcordant groups), (2) GLASS stages I-III, and (3) endovascular versus open strategies. The primary outcome was 5-year freedom from major adverse limb events (FF-MALE), defined as freedom from reintervention or major amputation, and secondary outcomes included 5-year overall survival, freedom from major amputation, freedom from reintervention, and immediate technical failure (ITF) during initial revascularization. Kaplan-Meier (KM) survival analysis and multivariate analysis with Cox proportional hazard models were performed on the primary and secondary outcomes.
RESULTS: Of 281 first-time revascularizations for CLTI, 251 (89.3%) were endovascular and 186 (66.2%) were in the concordant group, with a mean clinical follow-up of 3.02 ± 2.40 years. Within the concordant group alone, 167 (89.8%) of revascularizations were endovascular. The concordant group had a higher rate of chronic kidney disease (60.8% vs. 45.3%, P = 0.02), WIfI foot infection grade (0.81 ± 1.1 vs. 0.56 ± 0.80, P = 0.03), and WIfI stage (3.1 ± 0.79 vs. 2.8 ± 1.2, P < 0.01) compared to the non-concordant group. After both KM and multivariate analyses, there were no significant differences in 5-year FF-MALE or overall survival between concordant and non-concordant groups. There was higher freedom from major amputation in the non-concordant group on KM analysis (83.9% vs. 74.2%, P = 0.025), though this difference was non-significant on multivariate analysis (hazard ratio [HR]: 0.49, 95% confidence interval [CI]: 0.21-1.15, P = 0.10). The open group had lower MALE compared to the endovascular group (HR: 0.39, 95% CI: 0.17-0.91, P = 0.029) attributed to a lower reintervention rate in the open group (HR: 0.31, 95% CI: 0.11-0.87, P = 0.026). GLASS stage was not associated with significant differences in outcomes, but the severity of GLASS stage was associated with ITF (2.1% in stage 1, 6.4% in stage 2, and 11.7% in stage 3, P = 0.01).
CONCLUSIONS: In this study, CLTI treatment outcomes did not differ significantly based on whether treatment was received in concordance with GVG-recommended strategy. There was no difference in overall survival between the endovascular and open groups, though there was a higher reintervention rate in the endovascular group. The GVG guidelines are an important resource to help guide the management of CLTI patients. However, in this study, both concordance with GVG guidelines and GLASS staging were found to be indeterminate in differentiating outcomes between complex CLTI patients treated primarily with an endovascular-first approach. The revascularization approach for a CLTI patient is a nuanced decision that must take into account patient anatomy and clinical status, as well as physician skill and experience and institutional resources.

OBJECTIVE: This study aimed to investigate the long-term impact of guideline-directed medical therapy (GDMT) on 10-year mortality in patients with chronic limb-threatening ischaemia (CLTI) after revascularization.
METHODS: We performed a retrospective multicentre study enrolle 459 patients with CLTI who underwent revascularization (396 endovascular therapy [EVT] and 63 bypass surgery [BSX] cases) between January 2007 and December 2011. The primary outcome measure was all-cause mortality. We additionally explored the predictors for all-cause mortality using Cox regression hazard models; the influence of GDMT, defined as prescription of antiplatelet agents, statins, and angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) in aggregate, on all-cause mortality, and the association between baseline characteristics using interaction effects.
RESULTS: During the 10-year follow-up after revascularization, 234 patients died. In Kaplan-Meier analysis, 10-year mortality was significantly lower in patients who received statins (p＜.001) and ACE inhibitors or ARBs (p=.010) than those who did not. However, there were no differences in 10-year mortality between patients who received anti-platelet agents and those who did not (p=.62). Interaction analysis revealed that GDMT had a significantly different hazard ratio in patients who were and were not on hemodialysis and in those treated with EVT or BSX (p for interaction =.002 and .044, respectively). In the multivariate analysis, age ＞75 years, non-ambulatory status, hemodialysis, congestive heart failure, left ventricular ejection fraction ＜50%, and GDMT were significantly associated with all-cause mortality.
CONCLUSIONS: Appropriate GDMT use was independently associated with 10-year mortality in patients with CLTI after revascularization.

The Global Vascular Guidelines (GVGs) recommend initial revascularization (bypass or endovascular therapy) for chronic limb-threatening ischemia (CLTI) based on anatomical complexity and limb severity. This decision is made based on a prediction of the outcomes after endovascular intervention. This study was performed to evaluate outcomes after distal bypass in cases recommended for GVG bypass.
A total of 239 distal bypasses for CLTI were evaluated in 195 patients with a GVG bypass recommendation treated between 2009 and 2020 at a single center in Japan. Comparisons were made between crural and pedal bypass cases.
The 195 patients (median age, 77 years; 67% male) underwent 133 crural bypasses (106 patients; 54%) and 106 pedal bypasses (89 patients; 46%). Hemodialysis was more common in pedal cases than in crural cases (P = .03). Hospital deaths occurred in two cases (1%) within 30 days. The whole cohort has a follow-up rate of 96% over a mean of 28 ± 26 months, with 3-year limb salvage rates of 87% and 3-year primary, assisted primary, and secondary patency rates of 40%, 65%, and 67%, all without significant differences between crural and pedal cases. The 1-year wound healing rate was 88% and tended to be higher in crural cases than in pedal cases (P = .068). The 3-year survival rate was 52% in the cohort and did not differ significantly between crural and pedal cases.
Patients with CLTI with a GVG bypass recommendation had acceptable limb salvage, graft patency, wound healing, and survival after distal bypass, regardless of the bypass method. These findings indicate that a GVG bypass recommendation as an initial revascularization method is valid in the real world.

Clinical Practice Guideline for Limb Salvage or Early Amputation is based on a systematic review of current scientific and clinical research. The purpose of this clinical practice guideline is to address treatment for severe lower limb trauma below the distal femur by either amputation or limb salvage by providing evidence-based recommendations for key decisions that affect the management of patients with lower extremity trauma. This guideline contains 11 recommendations to evaluate the decision factors important for limb salvage versus early amputation. In addition, the work group highlighted the need for better research in the treatment and the shared decision making process of high-energy lower extremity trauma.

Marko Godina in his landmark paper in 1986 established the principle of early flap coverage for reconstruction of traumatic lower extremity injuries to minimize edema, fibrosis, and infection while optimizing outcomes. However, with the evolution of microsurgery and wound management, there is emerging evidence that timing of reconstruction is not as critical as once believed. Multidisciplinary care with a combined orthopedic and reconstructive approach is more critical for timely and appropriate definite treatment for severe lower extremity injuries.

BACKGROUND: The local treatment of Ewing sarcoma of bone involves surgery, radiotherapy or both. The selection of treatment depends on the anatomical extent of the tumour, the effectiveness of the proposed treatment, its morbidity, and the expectation of cure. However, not only are there variations in the approach to local treatment between individual patients, but also between treatment centres and countries. Our aim was to explore variation in practice and develop consensus statements about local treatment.
METHODS: A three stage modified Delphi technique was used with international collaborators. This involved an expert panel to identify areas of controversy, an online survey of international collaborators and a consensus meeting in London, UK in June 2017. In the consensus meeting, teams of clinicians discussed the local management of selected cases and their responses were collected with electronic voting.
RESULTS: Areas of greater or less consensus were identified. The lack of evidence underpinning different approaches was noted and areas for collaborative research became apparent.
CONCLUSIONS: This has demonstrated that there is an international consensus around many aspects of the local treatment of Ewing sarcoma of bone, including the use of specialist MultiDisciplinary Team (MDT) meetings with access to all appropriate treatments. However, considerable variation remains including the use of different staging investigations, decision making, definitions of response, and radiotherapy doses and timing. Further collaborative work should be undertaken to determine the impact of these variations in order to define best practice.
