Preoperative differential diagnosis of gastric submucosal tumors has generally been difficult because they are covered with normal mucosa. However, recent advances in endoscopic ultrasound (EUS)-guided sampling of submucosal gastrointestinal lesions have made it possible to achieve preoperative differential diagnosis of gastric submucosal tumors. A 76-year-old woman was referred to our hospital with a gastric submucosal tumor. The tumor was observed in the antrum of the stomach. It was preoperatively diagnosed as a schwannoma after immunohistochemical evaluation of a biopsy specimen, obtained using endoscopic ultrasound-guided fine needle aspiration...

Actinomycosis is a slowly progressive, chronic infectious disease. It is caused by the genus Actinomyces, which are gram-positive anaerobic bacteria. It presents as a mass-like lesion, composed of bacterial nidus and characteristic granulomatous inflammatory fibrosis. As such, it has frequently been mistaken for a malignancy. Surgical resection is a common procedure in these patients prior to a definite diagnosis. Although actinomycosis can occur in a variety of regions, including oral-cervicofacial, thoracic, and abdominopelvic cavities, the involvement of the pancreas is very rare...

BACKGROUND: Endobronchial ultrasound (EBUS) elastography is a new imaging procedure for describing the elasticity of intrathoracic lesions and providing important additional diagnostic information. OBJECTIVES: The aim of this study was to utilize the feasibility of qualitative and quantitative methods to evaluate the ability of EBUS elastography to differentiate between benign and malignant mediastinal and hilar lymph nodes (LNs) during EBUS-guided transbronchial needle aspiration (EBUS-TBNA)...

The successful clinical application of high intensity focused ultrasound (HIFU) ablation depends on reliable monitoring of the lesion formation. Harmonic motion imaging guided focused ultrasound (HMIgFUS) is an ultrasound-based elasticity imaging technique, which monitors HIFU ablation based on the stiffness change of the tissue instead of the echo intensity change in conventional B-mode monitoring, rendering it potentially more sensitive to lesion development. Our group has shown that predicting the lesion location based on the radiation force-excited region is feasible during HMIgFUS...

OBJECTIVE: To determine the negative predictive value of multiparametric-MRI (mpMRI), we evaluated the frequency of prostate cancer detection by 12-core template mapping biopsy in men whose mpMRI showed no suspicious regions. METHODS: 670 patients underwent mpMRI followed by transrectal ultrasound-(TRUS) guided systematic prostate biopsy from December 2012 to June 2016. Of this cohort, 100 patients had a negative mpMRI. mpMRI imaging sequences included T2-weighted, diffusion-weighted imaging, and dynamic contrast enhancement sequences...

This study investigates the safety profile for use of histotripsy, a non-invasive ultrasonic ablation method currently being developed for the treatment of liver cancer, for liver ablation in an in vivo porcine model. Histotripsy treatments were applied to the liver and hepatic veins of 22 porcine subjects, with half of the subjects receiving systemic heparinization. Vital signs (heart rate, blood pressure, temperature, electrocardiogram and SpO2) were monitored throughout the procedure and for 1 h post-treatment...

PURPOSE: During magnetic resonance (MR)-guided thermal therapies, water proton resonance frequency shift (PRFS) based MR temperature imaging can quantitatively monitor tissue temperature changes. It is widely known that the PRFS technique is easily perturbed by tissue motion, tissue susceptibility changes, magnetic field drift, and modality-dependent applicator induced artifacts. Here a referenceless Gaussian process modeling (GPM) based estimation of the PRFS is investigated as a methodology to mitigate unwanted background field changes...

PURPOSE: High intensity focused ultrasound (HIFU) is a non-invasive therapeutic technique that can thermally ablate tumors. Boiling histotripsy (BH) is a HIFU approach that can emulsify tissue in a few milliseconds. Lesion volume and temperature effects for different BH sonication parameters are currently not well characterized. In this work, lesion volume, temperature distribution, and area of lethal thermal dose were characterized for varying BH sonication parameters in tissue-mimicking phantoms (TMP) and demonstrated in ex vivo tissues...

BACKGROUND: The quest for an ideal sedative during regional anesthesia is on. Although propofol has been accepted as a sedative intraoperatively, it can be associated with troublesome hemodynamic changes. Dexmedetomidine is a new alpha 2 agonist used widely for sedation. AIMS: In this study, we tried to compare equivalent doses of dexmedetomidine infusion with propofol with emphasis on their effect on the hemodynamics. SETTINGS AND DESIGN: Prospective, single-blinded randomized controlled trial...

Ultrasound-guided regional anesthesia (UGRA), like other basic skills, should be learnt in a simulation laboratory before performing on the patient. Cadavers provide an ideal tool for learning sonoanatomy and skills required for performing UGRA. On the basis of preservation technique used, the cadavers can be formalin embalmed cadavers, Thiel cadavers (soft cadavers), and fresh frozen cadavers. We compared three types of cadavers for performing ultrasound-guided upper and lower limb blocks. We observed that fresh frozen and Thiel cadavers were less smelling and had more realistic appearance as compared to formalin embalmed cadavers...

Abscesses in the head and neck are relatively common diseases with varied symptoms and severities. These abscesses are usually caused by upper respiratory infections, trauma, foreign bodies, postoperative infections, malignancies or dental infections.(1,2) The regions where abscesses can develop in the head and neck, include fascial planes and potential spaces such as submandibular, sublingual, submental, parapharyngeal, retropharyngeal, pretracheal, masticator or infratemporal areas.(3) This article is protected by copyright...

PURPOSE: Post-transrectal ultrasound-guided prostate biopsy sepsis is an increasing problem in this era of rising antibiotic resistance. Ertapenem prophylaxis has proven very effective at our institution for reducing this, however has raised local and regional antimicrobial stewardship concerns. This study investigated the possible selective effect of single dose ertapenem prophylaxis on fecal colonization with carbapenem-resistant Enterobacteriaceae. MATERIALS AND METHODS: Patients had a rectal swab taken prior to receiving pre-biopsy ertapenem prophylaxis...

OBJECTIVE: Our objective was to describe the first reported use of an axillary brachial plexus block to treat the entrapment of a transradial artery catheter due to vasospasm. CASE REPORT: A 42-year-old man undergoing transradial arterial cardiac catheterization suffered arterial vasospasm causing the catheter to become entrapped and refractory to conservative (warm compresses) and standard pharmacologic interventions (intracatheter verapamil, intravenous infusions of nitroglycerin and nicardipine, and subcutaneous lidocaine and topical nitroglycerin)...

Postoperative pain after bariatric surgery can be significant and yet difficult to manage. These patients frequently have associated obstructive sleep apnea and are at risk of respiratory depression with opioid analgesia. Abdominal wall blocks such as the subcostal transversus abdominis plane block are not of significant benefit, probably in part because they provide only somatic analgesia. The ultrasound-guided erector spinae plane (ESP) block is a recently described regional anesthetic technique for providing thoracic analgesia when performed at the level of the T5 transverse process...

A fully-automatic ultrasound image processing system that can determine the needle entry site for epidural anesthesia (EA) in real time is presented in this paper. Neither the knowledge of anesthetists nor additional hardware is required to operate the system, which firstly directs the anesthetists to reach the desired insertion region in the longitudinal view, i.e., lumbar level L3-L4, and then locates the ideal puncture site by instructing the anesthetists to rotate and slightly adjust the position of ultrasound probe...

Surgery of the wrist and hand commonly involves regional anesthesia of the median nerve and superficial radial nerve within the forearm. In this sonographic study, the contribution of the lateral cutaneous nerve of forearm (LCNF) to thumb cutaneous sensation was studied. Patients scheduled for thumb suspension arthroplasty (n = 35) were examined by ultrasound, with LCNF, median nerve, and superficial radial nerve identified. A single nerve was then injected with local anesthetic, and the area of cutaneous sensory loss mapped at 15 minutes...
