Within the last 10 years there have been significant advances in minimal-access surgery. Although no emerging technology has demonstrated improved outcomes or fewer complications than standard laparoscopy, the introduction of the robotic surgical platform has significantly lowered abdominal hysterectomy rates. While operative time and cost were higher in robotic-assisted procedures when the technology was first introduced, newer studies demonstrate equivalent or improved robotic surgical efficiency with increased experience...

PURPOSE: To quantify the deformations of the femoropopliteal (FP) segment in patients undergoing endovascular revascularization and to compare the posttreatment deformations caused by primary nitinol stent implantation to those produced by percutaneous transluminal angioplasty (PTA). METHODS: Thirty-five patients (mean age 69±10 years; 20 men) scheduled for endovascular therapy were recruited for the study. During endovascular interventions, angiographic images were acquired with the legs straight and with a hip/knee flexion of 20°/70°...

After stenosis of arteriovenous vascular access in hemodialysis patients, platelets play a crucial role in subsequent thrombus formation, leading to access failure. In a previous study, the mean platelet volume (MPV)/platelet count ratio, but not MPV alone, was shown to be an independent predictor of 4-year mortality after myocardial infarction. However, little is known about the potential influence of MPV/platelet count ratio on vascular access patency in hemodialysis patients. A total of 143 patients undergoing routine hemodialysis were recruited between January 2013 and February 2016...

BACKGROUND: The impact of endovascular revascularization of the lower extremity arteries with atherectomy (AT) compared with percutaneous transluminal angioplasty (PTA) is still unclear. Therefore, the aim of the study was to compare long-term outcomes after percutaneous PTA and AT in patients requiring endovascular revascularization.Methods and Results:This was a single-center, retrospective registry of obstructive and symptomatic PAD patients who underwent endovascular revascularization...

BACKGROUND: In natural orifice transluminal endoscopic surgery (NOTES) the peritoneal cavity is reached through natural orifices (mouth, rectus and transvaginal duct), by means of little cuttings in the walls of hollow organs. Due to narrow spaces, NOTES needs robotic systems to assure operation/movement precision and patient safety. Variable stiffness actuation (VSA) assures both requirements. METHODS: The authors developed a grasper for NOTES, provided with VSA, to use as an end-effector for snail robot devices...

Purpose Percutaneous remote access for endovascular aortic repair is an advantageous alternative to open access. Previous surgery in the femoral region and the presence of synthetic vascular grafts in the femoral/iliac arteries represent major limitations to percutaneous remote access. The aim of this study was to evaluate an original technique used for enabling percutaneous remote access for thoracic or abdominal endovascular aortic repair in patients with scar tissue and/or a vascular graft in the groin. Methods Twenty-five consecutive patients with a thoracic (11/25; 44%) or an aortic aneurysm (14/25; 66%) and with a synthetic vascular graft in the groin (16/25; 64%) or a redo groin access (9/25; 36%) were managed through the percutaneous remote access...

The development and popularization of minimally invasive treatment is gradually evolving in the course of human fighting against disease. Minimally invasive surgery has been widely accepted and carried out because of the advantages of smaller trauma, less pain, little impact on the body and physiological metabolism of the body. The evidence-based medicine makes it important to conduct clinical trials to confirm the technical and oncological safety. With the development of minimally invasive technologies, including three-dimensional laparoscopic, natural orifice transluminal endoscopic surgery, robotic surgery system, minimally invasive surgery are providing more opportunities and challenges for gastrointestinal diseases...

BACKGROUND: Natural orifice transluminal endoscopic surgery developed for neck surgery become increasing popular. Herein, an innovative transoral endoscopic parathyroidectomy vestibular approach (TOEPVA) was developed for primary hyperparathyroidism (PHPT) and renal hyperparathyroidism (rHPT). METHODS: Incisions were made at the oral vestibule under the inferior lip. A 10-mm trocar was inserted through the center of the oral vestibule with two 5-mm trocars laterally...

INTRODUCTION: Natural orifice transluminal endoscopic surgery (NOTES) is a challenging minimally invasive procedure. Although laparoscopic techniques for liver resection are gaining acceptance worldwide, few studies have investigated NOTES liver resection. We used a porcine model to assess the feasibility and safety of transvaginal NOTES liver resection (TV NOTES LR). MATERIALS AND METHODS: Nine female pigs underwent TV NOTES LR. A nonsurvival acute porcine model with general anesthesia was used in all cases...

BACKGROUND: The widespread use of central venous catheters, ports, pacemakers, and defibrillators has increased the incidence of benign superior vena cava syndrome (SVCS). This study aimed at reviewing the results of open and endovascular treatment of SVCS. METHOD: Medical literature databases were searched for relevant studies. Studies with more than five adult patients, reporting separate results for the SVC were included. Nine studies reported the results of endovascular treatment of SVCS including 136 patients followed up for a mean of 11-48 months...

There is no clinical report on the use of natural orifice transluminal endoscopic surgery (NOTES) for the management of patients with large liver cysts.This study aims to evaluate the feasibility and safety of NOTES for liver cyst fenestration in humans using a currently available technique.From February 2009 to June 2010, 4 cases of transgastric endoscopic liver cyst fenestration were performed; in which 3 cases received NOTES only, while 1 case received additional laparoscopic assistance.Mean time to endoscopically locate the liver cyst was 16 minutes (5-22 minutes)...

OBJECTIVE: Historically, edge stenosis and late thrombosis limited the effectiveness of adjunctive endovascular brachytherapy (EVBT) for in-stent restenosis (ISR) after percutaneous transluminal angioplasty (PTA) and stenting. We evaluated an updated protocol of PTA and EVBT for ISR among patients with lower extremity occlusive disease. METHODS: This is a retrospective, single-center review of patients treated with PTA and EVBT for ISR in the iliac and femoropopliteal segments between 2004 and 2012...

We report our activities training doctors on vascular access procedures at International University (IU) Hospital in Cambodia through a program facilitated by Ubiquitous Blood Purification International, a nonprofit organization that provides medical support to developing countries in the field of dialysis medicine. Six doctors from Japan have been involved in the education of medical personnel at IU, and we have collectively visited Cambodia about 15 times from 2010 to 2016. In these visits, we have performed many operations, including 42 for arteriovenous fistula, 1 arteriovenous graft, and 1 percutaneous transluminal angioplasty...

BACKGROUND: Endovascular therapy for long femoropopliteal lesions using percutaneous transluminal balloon angioplasty or first-generation of peripheral stents has been associated with unacceptable one-year restenosis rates. However, with recent advances in equipment and techniques, a better primary patency rate is expected. So, this study was conducted to detect the long-term primary patency rate of nitinol self-expandable stents implanted in long, totally occluded femoropopliteal lesions (TASC II type C & D), and determine the predictors of reocclusion or restenosis in the stented segments...
