In diabetic retinopathy, the exact mechanisms leading to retinal capillary closure and to retinal barriers breakdown remain imperfectly understood. Rho-associated kinase (ROCK), an effector of the small GTPase Rho, involved in cytoskeleton dynamic regulation and cell polarity is activated by hyperglycemia. In one year-old Goto Kakizaki (GK) type 2 diabetic rats retina, ROCK-1 activation was assessed by its cellular distribution and by phosphorylation of its substrates, MYPT1 and MLC. In both GK rat and in human type 2 diabetic retinas, ROCK-1 is activated and associated with non-apoptotic membrane blebbing in retinal vessels and in retinal pigment epithelium (RPE) that respectively form the inner and the outer barriers...

INTRODUCTION AND AIM: Surgical vasectomy remains the gold standard for fertility control in men. Endoluminal occlusion of the seminal ducts, thus avoiding an external incision, may become an appealing alternative to this approach. As our group has shown, nontraumatic endoscopic inspection of the seminal ducts is feasible in the human cadaver. We investigated the feasibility and reliability of occlusion using several commercially available medical sealing agents in the porcine vas deferens (VD)...

BACKGROUND AND PURPOSE: Flow diverters are emerging as an endovascular treatment alternative for proximally located intracranial aneurysms. However, treatment of aneurysms at and beyond the circle of Willis is not well-established. We assessed the clinical safety and efficacy of the Flow Re-Direction Endoluminal Device Jr (FRED Jr) dedicated to small-vessel diameters between 2.0 and 3.0 mm. MATERIALS AND METHODS: This was a multicenter observational clinical study of 42 patients with 47 aneurysms treated by a flow-direction technique with the FRED Jr...

BACKGROUND AND STUDY AIMS : Endoscopic ultrasound-guided fine needle aspiration (FNA) for gastrointestinal subepithelial lesions (SELs) has limited diagnostic accuracy due to technical problems and small lesion size. We previously reported a novel submucosal tunneling biopsy (STB) technique for sampling SELs. This study aimed to evaluate the diagnostic ability and safety of STB compared to that of FNA for SELs. PATIENTS AND METHODS : The study was a non-randomized, prospective comparative study with crossover design in patients with endoluminal gastric SELs...

PURPOSE OF REVIEW: Gastric outlet obstruction (GOO) can result from benign and malignant causes. Until recently, surgical gastrojejunostomy was the treatment of choice for patient with benign and malignant GOO with a good functional status. Endoscopic placement of luminal self-expandable metal stents is currently widely accepted as the first line of treatment for malignant GOO because of its effectiveness and minimally invasive nature. The main shortcoming of luminal stents is the high incidence of recurrent GOO most commonly because of tumor ingrowth/overgrowth...

Many patients with massive lower gastrointestinal (GI) haemorrhage from diverticulosis are subjected to total colectomy when preoperative localisation is unavailable. We dissected colectomy specimens and noted that there was limited retrograde reflux in most of these cases. Therefore, we sought to assess the value of a positive endoluminal erythrocyte presence (PEEP) test (presence of fresh blood in the caecum) to direct segmental colectomies in 14 patients who required emergency operations for massive lower GI haemorrhage...

INTRODUCTION: Several surgical treatments exist for treatment of gastroparesis, including gastric electrical stimulation, pyloroplasty, and gastrectomy. Division of the pylorus by means of endoscopy, Per-Oral Pyloromyotomy (POP), is a newer, endoluminal therapy that may offer a less invasive, interventional treatment option. METHODS: We describe and present a video of our step by step technique for POP using a lesser curvature approach. The following are technical steps to complete the POP procedure from the lesser curve approach...

We designed a novel 6-point electrochemical impedance spectroscopy (EIS) sensor with 15 combinations of permutations for the 3-D mapping and detection of metabolically active atherosclerotic lesions. Two rows of 3 stretchable electrodes circumferentially separated by 120° were mounted on an inflatable balloon for intravascular deployment and endoluminal interrogation. The configuration and 15 permutations of 2-point EIS electrodes allowed for deep arterial penetration via alternating current (AC) to detect varying degrees of lipid burden with distinct impedance profiles (Ω)...

INTRODUCTION: Abdominal aortic aneurysms (AAA) account for approximately 400 deaths per year in New Zealand (NZ). Waikato Hospital caters to a diverse population comprising a high proportion of the indigenous Māori ethnic group considered to be at higher risk of mortality and morbidity. Despite these population factors, there is no screening program for AAA. The aim of this study was to further define the epidemiology and outcomes of AAA repairs in NZ to investigate the utility of implementing a population-specific screening program...

PURPOSE OF REVIEW: This review aims to discuss the putative relationship between hiatus hernia and dysphagia. RECENT FINDINGS: Proposed mechanisms of dysphagia in patients with hiatus hernia are usually difficult to identify, but recent advances in technology (high-resolution manometry with or without concomitant impedance, ambulatory pH with impedance, videofluoroscopy, and the endoluminal functional lumen imaging probe (EndoFLIP)) and methodology (inclusion of swallows of various consistencies and volumes or shifting position during the manometry protocol) can help induce symptoms and identify the underlying disorder...

INTRODUCTION: Anastomotic leaks are uncommon yet potentially devastating complications after bariatric surgery. While the initial management includes resuscitation and sepsis control, the definitive management often requires endoscopic or surgical interventions. Surgical revision of the initial surgery may be necessary for chronic non-healing fistula. PATIENTS AND METHODS: The patient is a 45-year-old female with history of laparoscopic adjustable gastric banding who underwent band removal and conversion to a sleeve gastrectomy (SG) due to her failed weight loss, which resulted in a leak at gastroesophageal junction...

Non-infectious aortitis is usually due to giant-cell arteritis, Takayasu disease or Behçet disease. The main aortic lesions are stenoses, occlusions and aneurysms in the Takayasu disease and aneurysms in the Behçet disease and giant-cell arteritis. Treatment is based on corticosteroid therapy and surgery. Endoluminal management is now the rule. We report a retrospective descriptive study of 10 patients who underwent surgical or endoluminal management of inflammatory lesions of the aorta between January 2000 and December 2015...

PURPOSE: Catheter-based ultrasound applicators can generate thermal ablation of tissues adjacent to body lumens, but have limited focusing and penetration capabilities due to the small profile of integrated transducers required for the applicator to traverse anatomical passages. This study investigates a design for an endoluminal or laparoscopic ultrasound applicator with deployable acoustic reflector and fluid lens components, which can be expanded after device delivery to increase the effective acoustic aperture and allow for deeper and dynamically adjustable target depths...

Adequate biliary drainage with endoscopic or percutaneous placement of self-expandable metal stents represents the goal of palliation in patients with inoperable malignant obstruction of the biliary tree. As an adjunct to stenting, various tissue ablation treatments have been proposed with conflicting results. The aim of this study was to test the effect on biliary tissue of a new ablation technique based on Nd:YAG laser light delivery. The study was conducted on ex vivo specimens of 18 healthy farm pigs, using cystic ducts that are the simplest biliary structures to isolate and cannulate ex vivo...

Continuous-flow left ventricular assist devices (CF-LVADs) have significantly improved outcomes for patients with end-stage heart failure when used as a bridge to cardiac transplantation or, more recently, as destination therapy. However, its implantations carries a risk of complications including infection, device malfunction, arrhythmias, right ventricular failure, thromboembolic disease, postoperative and nonsurgical bleeding. A significant number of left ventricular assist devices (LVAD) recipients may experience recurrent gastrointestinal hemorrhage, mainly due to combination of antiplatelet and vitamin K antagonist therapy, activation of fibrinolytic pathway, acquired von Willebrand factor deficiency, and tendency to develop small intestinal angiodysplasias due to increased rotary speed of the pump...
