We conducted a literature review of natural orifice transluminal endoscopic surgery (NOTES), focusing on urologic procedures with gastrointestinal tract access, to update on the development of this novel surgical approach. As part of the methods, a comprehensive electronic literature search for NOTES was conducted using PubMed and Cochrane Library from March 2002 to February 2016 for papers reporting urologic procedures performed utilizing gastrointestinal tract access. A total of 11 peer-reviewed studies examining utility of gastrointestinal access for NOTES urologic procedures were noted, with the first report in 2007...

BACKGROUND AND AIMS: EUS-guided transluminal drainage (EUS-TD) and sequential direct endoscopic necrosectomy (DEN) for pancreatic fluid collections (PFCs) using a dedicated biflanged metal stent (BFMS) has been reported as a useful alternative to using plastic stents or a conventional metal stent. However, current dedicated BFMSs have limitations. Recently, a new BFMS with solidly constructed biflanges and various stent lengths matched to the PFC condition has been developed. Herein, we prospectively evaluated this new BFMS for the treatment of PFCs...

Objective Percutaneous transluminal renal artery angioplasty (PTRA) has been recommended for the treatment of renovascular resistant hypertension. However, large randomized trials have reported that PTRA did not improve the outcomes compared with optimal medical therapy in patients with renal artery stenosis (RAS). It is important to identify patients with renovascular hypertension who are likely to respond to PTRA. We herein examined whether or not the plasma renin activity (PRA) could predict the improvement in resistant hypertension after PTRA for RAS...

Central Aortic Pressure (CAP) can be used to predict cardiovascular structural damage and cardiovascular events, and the development of simple, well-validated and non-invasive methods for CAP waveforms estimation is critical to facilitate the routine clinical applications of CAP. Existing widely applied methods, such as generalized transfer function (GTF-CAP) method and N-Point Moving Average (NPMA-CAP) method, are based on clinical practices, and lack a mathematical foundation. Those methods also have inherent drawback that there is no personalisation, and missing individual aortic characteristics...

Endovascular revascularization as treatment of atherosclerotic renal-artery stenosis (aRAS) is controversial since 3 large and multicentric randomised trials (CORAL, ASTRAL, STAR) failed to prove the superiority of percutaneous transluminal renal-artery stenting (PTRAS) over medical treatment only (MT). However, considering the multiple bias of these trials, among which questionable inclusion criterias, these results must be extrapolated in clinical practice with caution. New pathophysiological data have been helping to understand why restoring blood flow does not necessarily lead to kidney function improvement...

With advances in natural orifice transluminal endoscopic surgery, peroral endoscopic myotomy (POEM) has become a novel treatment for esophageal achalasia. In this study, we investigated the feasibility and safety of POEM in patients with achalasia after failed endoscopic interventions. Data on all patients undergoing POEM treatment of achalasia were collected prospectively. We enrolled 61 patients who underwent POEM for achalasia between July 2011 and January 2014. The preoperative intervention group included patients who had undergone botulinum toxin injection or pneumatic balloon dilation before POEM...

: Walled-off pancreatic necrosis is a late complication of severe acute pancreatitis that generally needs some interventions. The aim of this review is to analyse the indications, technical aspects and limits of these therapeutic options. The development of the walled-off pancreatic necrosis needs 4-6 weeks from the onset of the disease. The necrosectomy is recommended after this time. Endoscopic necrosectomy offers good results if the necrosis is in retrogastric or retroduodenal localisations...

BACKGROUND: Video-assisted mediastinoscopy (VAM) represents the standard procedure for mediastinal lymph node biopsies. This operation results in a scar at prominent position at the anterior neck. Since there is a trend to less invasive procedures, natural orifice transluminal endoscopic surgery (NOTES) was introduced to different fields of surgery. Based on NOTES we developed a new approach for mediastinoscopy: transoral endoscopic mediastinal surgery (TOEMS). In previous studies using human cadavers and living pigs the feasibility of TOEMS was shown...

Renal artery stenosis (RAS) is the most common vascular complication following renal transplantation. Percutaneous endovascular transluminal angioplasty with stenting is the treatment of choice for clinically significant RAS. We present a case describing a novel combined trans-renal parenchyma and trans-femoral approach to repairing a disrupted transplant renal artery stent. Our patient's allograft RAS was initially managed by standard percutaneous approach, but during follow-up the stent became disrupted and crushed causing partial occlusion of the renal artery...

Subintimal angioplasty of lower limb arterial occlusion carries a relatively higher risk of vessel perforation compared to transluminal angioplasty. Vessel perforation is a potentially life threatening complication which requires prompt recognition and management. They are usually managed by endovascular techniques such as low-pressure balloon tamponade, covered stents, and coil embolization of the ruptured artery. We describe a technique of treating vessel perforation following balloon angioplasty. Patient developed a large perforation of the proximal superficial femoral artery (SFA) after balloon inflation during subintimal angioplasty of complete SFA occlusion...
