Endoscopic Internal Drainage with Enteral Nutrition (EDEN) for Treatment of Leaks Following Sleeve Gastrectomy

Background

Endoscopic treatment of gastric leaks (GL) following sleeve gastrectomy (SG) involves different techniques; however, standard management is not yet established. We report our experience about endoscopic internal drainage of leaks using pigtail stents coupled with enteral nutrition (EDEN) for 4 to 6 weeks until healing is achieved.

Methods

In 21 pts (18 F, 41 years), one or two plastic pigtail stents were delivered across the leak 25.6 days (4–98) post-surgery. In all patients, nasojejunal tube was inserted. Check endoscopy was done at 4 to 6 weeks with either restenting if persistent leak, or removal if no extravasation of contrast in peritoneal cavity, or closure with an Over-the-Scope Clip® (OTSC®) if contrast opacifying the crossing stent without concomitant peritoneal extravasation.

Results

Twenty-one out of 21 (100 %) patients underwent check endoscopy at average of 30.15 days (26–45) from stenting. In 7/21 (33.3 %) patients leak sealed, 2/7 needed OTSC®. Second check endoscopy, 26.7 days (25–42) later, showed sealed leak in 10 out 14; 6/10 had OTSC®. Four required restenting. One patient, 28 days later, needed OTSC®. One healed at 135 days and another 180 days after four and seven changes, respectively. One patient is currently under treatment. In 20/21 (95.2 %), GL have healed with EID treatment of 55.5 days (26–?180); all are asymptomatic on a normal diet at average follow-up of 150.3 days (20–276).

Conclusions

EDEN is a promising therapeutic approach for treating leaks following SG. Multiple endoscopic sessions may be required.     

Successful lifestyle modifications may underlie umbilical cord-mesenchymal stromal cell effects in type 2 diabetes mellitus

Type 2 diabetes mellitus(T2DM) is a lifelong condition and a grave threat to human health. Innovative efforts to relieve its detrimental effects are acutely needed. The sine qua non in T2DM management is consistent adherence to a prudent lifestyle and nutrition, combined with aerobic and resistance exercise regimens, together repeatedly shown to lead to complete reversal and even longterm remission. Non-adherence to the above lifestyle adjustments condemns any treatment effort and ultimately the...     

Evaluation of foot hypoperfusion and estimation of percutaneous transluminal angioplasty outcome in patients with critical limb ischemia using intravoxel incoherent motion microperfusion MRI

Objectives:To emerge hypoperfusion of lower limbs in patients with critical limb ischemia (CLI) using Intravoxel Incoherent Motion microperfusion magnetic resonance imaging (IVIM-MRI). Moreover to examine the ability of IVIM-MRI to differentiate patients with severe peripheral arterial disease (PAD) from normal subjects and evaluate the percutaneous transluminal angioplasty (PTA) results in patients with CLI.Methods:Eight patients who presented with CLI and six healthy volunteers were examined. The patients underwent IVIM-MRI of lower extremity before and following PTA. The imaging protocol included sagittal diffusion-weighted (DW) sequences. DW images were analyzed and color parametric maps of the micro-circulation of blood inside the capillary network (D*) were constructed. The studies were evaluated by two observers to define interobserver reproducibility.Results:Technical success was achieved in all patients (8/8). The mean ankle-brachial index increased from 0.35 ± 0.2 to 0.76 ± 0.25 (p < 0.05). Successful revascularization improved IVIM microperfusion. Mean D* increased from 279.88 ± 13.47 10⁻⁵ mm²/s to 331.51 ± 31 10⁻⁵ mm²/s, following PTA, p < 0.05. Moreover, PAD patients presented lower D* values as compared to healthy individuals (279.88 ± 13.47 10⁻⁵ mm²/s vs 332.47 ± 22.95 10⁻⁵ mm²/s, p < 0.05, respectively). Good interobserver agreement was obtained with an ICC = 0.84 (95% CI 0.64–0.93).Conclusions:IVIM-MRI can detect differences in microperfusion between patients with PAD and healthy individuals. Moreover, significant restitution of IVIM microperfusion is found following successful PTA.Advances in knowledge:IVIM-MRI is a safe, reproducible and effective modality for evaluation of lower limb hypoperfusion in patients with PAD. It seems also to be a helpful tool to detect changes of tissue perfusion in patients with CLI following revascularization.     

The current status of risk-stratified breast screening

Apart from high-risk scenarios such as the presence of highly penetrant genetic mutations, breast screening typically comprises mammography or tomosynthesis strategies defined by age. However, age-based screening ignores the range of breast cancer risks that individual women may possess and is antithetical to the ambitions of personalised early detection. Whilst screening mammography reduces breast cancer mortality, this is at the risk of potentially significant harms including overdiagnosis with overtreatment, and psychological morbidity associated with false positives. In risk-stratified screening, individualised risk assessment may inform screening intensity/interval, starting age, imaging modality used, or even decisions not to screen. However, clear evidence for its benefits and harms needs to be established. In this scoping review, the authors summarise the established and emerging evidence regarding several critical dependencies for successful risk-stratified breast screening: risk prediction model performance, epidemiological studies, retrospective clinical evaluations, health economic evaluations and qualitative research on feasibility and acceptability. Family history, breast density or reproductive factors are not on their own suitable for precisely estimating risk and risk prediction models increasingly incorporate combinations of demographic, clinical, genetic and imaging-related parameters. Clinical evaluations of risk-stratified screening are currently limited. Epidemiological evidence is sparse, and randomised trials only began in recent years.Subject terms: Breast cancer, Cancer epidemiology
