Single pulmonary nodules are a difficult to diagnose imagining artifact. Currently novel diagnostic tools such as Radial-EBUS with or not C-ARM flouroscopy, electromagnetic navigation systems, robotic bronchoscopy and cone beam-compuer tomography (CBCT) can assist in the optimal guidance of biopsy equipment. After diagnosis of lung cancer or metastatic disease as pulmonary nodule, then surgery or ablation methods as local treatment can be applied. The percutaneous ablation systems under computed tomography guidance with radiofrequency, microwave, cryo and thermosphere have been used for several years...

The purpose of this study was to determine whether retention of a post-pyloric Dobhoff tube (DHT) in position to serve as a visual guide through the pylorus during gastrojejunostomy (GJ) tube placement results in a reduction in fluoroscopy time, procedure time, and estimated radiation dose. A retrospective study evaluated patients who underwent GJ tube placement or gastric to GJ conversion from January 1, 2017, to April 1, 2021. Demographic and procedural data were collected, and results were evaluated using descriptive statistics and hypothesis testing through an unpaired Student's t-test...

BACKGROUND: Self-expandable metallic (SEM) airway stents are an important approach to treating malignant central airway obstruction (CAO). Standard over-the-while (OTW) stent needs the guidance of a guide-wire. It should be implanted under flouroscopy or the guidance of bronchoscope visualization. In this study, we evaluated the operation time and safety between OTW stent and a novel through-the-scope (TTS) SEM airway stent. METHODS: In this multi-center, randomized, parallel-group superiority study, malignant CAO patients were enrolled randomly assigned (2:1) to the TTS stent implantation group (TTS group) or the standard OTW stent group (OTW group) in six sites across China...

BACKGROUND: Over the past decade, several minimally invasive mechanical support devices have been introduced into clinical practice to support the right ventricle (RV). Percutaneous cannulas are easy to insert, minimally invasive, and treat acute RV failure rapidly. In December 2021, the Food and Drug Administration approved a new 31 French dual lumen single cannula for use as a right ventricular assist device. AIMS: Descirbe the use of the new dual lumen percutaneous right ventricular assist device (RVAD) cannula...

BACKGROUND: The single procedure success rates of durable pulmonary vein isolation (PVI) for paroxysmal atrial fibrillation (AF) vary between 80% and 90%. This prospective, randomized study investigated the efficacy of cryoballoon PVI (CBA) versus PVI with radio-frequency (RF)-energy following the CLOSE protocol (ablation index [AI], interlesion distance ≤6 mm, surround flow catheter) in terms of single-procedure arrhythmia-free outcome and safety. METHODS AND RESULTS: A total number of 150 patients undergoing de novo catheter ablation for paroxysmal AF were randomized to two different treatment arms...

To evaluate the efficacy of a unique imaging software "OptiVision" on the confidence of stone identification using X-ray imaging during shockwave lithotripsy. A total of 57 patients with solitary radio-opaque kidney stones sized < 15 mm were included and evaluated with appropriate radiological imaging and laboratory studies before undergoing shockwave lithotripsy (SWL). The size of the stones was measured on KUB and CT images using maximal stone diameters. All patients were evaluated with radiography on the Dornier Delta III immediately before SWL and at the end of the SWL session with fluoroscopy, a snapshot image, and the OptiVision modality (applied over the acquired snapshot image without additional radiation exposure) for precise identification of the stone...

The direct anterior approach to the hip for total joint arthroplasty has been suggested to have several advantages compared to other popular approaches through its use of a natural intramuscular and intra-nervous interval. Recent emphasis on tissue sparing and minimally invasive outpatient joint replacements has given rise to a significant increase in the utilization of direct anterior total hip arthroplasty (DAA). Proponents of this approach cite improved recovery times, lower pain levels, improved patient satisfaction as well as improved accuracy on both implant placement/alignment and leg length restoration...

Pelvic instrumentation for neuromuscular scoliosis has been part of neuromuscular scoliosis surgery since the era of the Luque Galveston construct. Unit Rod (Medtronic Sofamor-Danek, Nashville, TN) instrumentation brought with it the concept of cantilever correction by placing the implants in the pelvis and then gradually bringing the rod to the spine by sequentially tightening the sublaminar wires, with the goal of creating a level pelvis over a straight spine. More recently surgeons have utilized pedicle screw constructs in which the corrective strategies have varied...

Catheter ablation via the femoral vein has been widely used in children. However, in certain conditions, an alternative vascular access is required for a successful ablation. Herein we reported that, accessory pathways (APs) and ectopic foci which reside right anterior and anterolateral to tricuspid valve orifice can be safely and effectively ablated with transjugular venous approach. Eleven procedures performed via the transjugular venous approach were reviewed retrospectively from the 355 electrophysiological procedures performed between March 2016 and November 2017...

OBJECTIVE: The aim of this study was to present outcomes of our patients who had undergone retrograde intrarenal surgery (RIRS) with fluoroscopy-free technique and evaluate the efficacy and safety of the technique. MATERIAL AND METHODS: Between January 2013 and June 2015 the outcomes of 93 patients who had undergone RIRS with fluoroscopy-free technique were retrospectively evaluated. Our RIRS technique involved preoperative assessment of ureter by semi-rigid ureteroscope, inserting guidewire through semi-rigid ureteroscope, inserting ureteral access sheath over the guidewire with the visiual guidance of semi-rigid ureteroscope, passing flexible ureteroscope through the sheath, dusting the stone with holmium laser, rechecking the ureter with semi-rigid ureteroscope and inserting double J stent through semi-rigid ureteroscope...

INTRODUCTION: Previous studies have suggested that there is a positive correlation between the extent of video gaming and efficiency of surgical skill acquisition on laparoscopic and endovascular surgical simulators amongst trainees. However, the link between video gaming and orthopaedic trauma simulation remains unexamined, in particular dynamic hip screw (DHS) stimulation.

PURPOSE: Exposure to ionizing radiation during electrophysiologic procedures in children is believed to increase the risk of future malignancy. Electroanatomical navigation can reduce exposure, but the cohort of children who derive the greatest benefit from this approach is incompletely defined. We sought to determine factors associated with fluoroscopy exposure with conventional catheter ablation versus electroanatomical navigation. METHODS: A retrospective review of all ablation procedures over a 5-year period during the transition to electroanatomical navigation performed by a single electrophysiologist was performed...
