PURPOSE OF REVIEW: Current imaging techniques (X-ray, computed tomography scan, ultrasound) have limitations in the identification and quantification of pulmonary diseases, in particular, on highly detailed level. The purpose of this review is to provide an overview of the current knowledge of innovative light- and laser-based imaging techniques that might fill this gap. RECENT FINDINGS: Optical coherence tomography (OCT) and confocal laser endomicroscopy (CLE) are high-resolution imaging techniques, which, combined with bronchoscopy, provide 'near histology' detailed imaging of the airway wall, lung parenchyma, mediastinal lymph nodes, and pulmonary vasculature...

BACKGROUND: Pancreatic tumors often represent primary neoplasms, however organ involvement with metastatic disease can occur. The use of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) to determine the underlying pathology provides guidance of clinical management. METHODS: 25 cases were identified in a retrospective review of our institution's records from 2006 to 2016. Clinical parameters and prognosis are described. RESULTS: Metastatic lesions to the pancreas diagnosed by EUS-FNA accounted for 4...

BACKGROUND: Transversus abdominis plane (TAP) block provides effective postoperative analgesia after abdominal surgeries. It can be also a useful strategy to reduce perioperative opioid consumption, support intraoperative hemodynamic stability and promote early recovery from anesthesia. The aim of this prospective randomized double-blind study was to assess the effect of subcostal TAP blocks on perioperative opioid consumption, hemodynamic and recovery time in living liver donors. METODS: The prospective, double-blinded, randomized controlled study was conducted with 49 living liver donors, aged 18-65 years, who were scheduled to undergo right hepatectomy...

Inability to cross the lesion with a guidewire is the most common reason for failure in percutaneous revascularization (PCI) of chronic total occlusions (CTOs). An ostial or stumpless CTO is an acknowledged challenge for CTO recanalization due to difficulty in successful wiring. IVUS imaging provides the opportunity to visualize the occluded vessel and to aid guidewire advancement. We review the value of this technique in a single-centre experience of CTO PCI. This series involves 22 patients who underwent CTO-PCI using IVUS guidance for stumpless CTO wiring at our institution...

PURPOSE: The aim of this study was to evaluate the effects of a preoperative popliteal block on sevoflurane consumption, postoperative pain, and analgesic consumption in children with cerebral palsy (CP) following lower limb surgery. METHODS: Fifty-four patients undergoing lower limb surgery were randomized to receive either a popliteal block + general anaesthesia (group P, n = 27) or general anaesthesia without a popliteal block (group C, n = 27). After anesthesia induction with 50% N2O, O2, and 8% sevoflurane, a popliteal block was given to group P patients with ultrasound guidance as a single dose of 0...

BACKGROUND AND OBJECTIVES: Glossopharyngeal nerve (GPN) blocks are usually performed by topical, intraoral, or peristyloid approaches, which carry significant complication risks due to the proximity of important neurovascular structures. This study presents a proof of concept for a new ultrasound (US)-guided technique, which would block the GPN distally, in the parapharyngeal space, away from the immediate vicinity of high-risk collateral structures. METHODS: Five cadaver heads were dissected, and the location of the GPN was explored bilaterally...

OBJECTIVES: The management of incidentally detected gallbladder polyps on radiological examinations is contentious. The incidental radiological finding of a gallbladder polyp can therefore be problematic for the radiologist and the clinician who referred the patient for the radiological examination. To address this a joint guideline was created by the European Society of Gastrointestinal and Abdominal Radiology (ESGAR), European Association for Endoscopic Surgery and other Interventional Techniques (EAES), International Society of Digestive Surgery - European Federation (EFISDS) and European Society of Gastrointestinal Endoscopy (ESGE)...

We report the application of ultrasound prescans for spinal anesthesia to morbid obesity patient. A 38-year-old woman with a body mass index (BMI) of 50 (weight: 110 kg; height: 148 cm) was scheduled to undergo pilonidal cyst resection at the bottom of the tailbone. Spinal anesthesia was selected for the procedure, because the patient's position during the surgery was prone and the patient had morbid obesity. To determine the spinal needle insertion point and the distance between the skin and dura, we planned to use ultrasound...

The management of pain after burn injuries is a clinical challenge magnified in patients with significant comorbidities. Presently, burn pain is treated via a wide variety of modalities, including systemic pharmacotherapy and regional analgesia. Although the latter can provide effective pain control in patients with burn injuries, it is relatively underused. Furthermore, the development of ultrasound guidance has allowed for novel approaches and sparing of motor nerve blockade with preference toward sensory-specific analgesia that has not been possible previously...

Real-time guidance of needle advancement has transformed Endoscopic Ultrasound from a diagnostic to an interventional procedure. EUS guided fine needle puncture has application in various interventional procedures (drainage of pseudocyst, biliary intervention, and injection of drugs). Celiac plexus or ganglion neurolysis for pain control is the major current EUS-guided fine-needle injection procedure. Feasibility and safety to accurately position needle devices and/or inject under real time EUS imaging with precise delivery of interventional agent have expanded the use of EUS to ablate tumor...

PURPOSE: Bedside vascular ultrasound machines are increasingly available. They are used to facilitate safer vascular access across a number of different specialties. In the electrophysiology laboratory however, where patients are frequently anticoagulated and require the insertion of multiple venous sheaths, anatomical landmark techniques predominate. Despite the high number of vascular complications associated with electrophysiological procedures and the increasing evidence to support its use in electrophysiology, ultrasound remains underutilised...

Both theoretical and experimental studies were performed here to investigate the lesion formation induced by high-intensity focused ultrasound (HIFU) operating in continuous scanning mode along a spiral pathway. The Khokhlov-Zabolotskaya-Kuznetsov equation and bio-heat equation were combined in the current model to predict HIFU-induced temperature distribution and lesion formation. The shape of lesion and treatment efficiency were assessed for a given scanning speed at two different grid spacing (3mm and 4mm) in the gel phantom studies and further researched in ex vivo studies...
