Outcomes and limitations of endoscopic ultrasound-guided hepaticogastrostomy in malignant biliary obstruction.

BMC Gastroenterol 2021 May 5;21(1):202. Epub 2021 May 5.

Department of General, Gastroenterological and Oncological Surgery, Collegium Medicum Nicolaus Copernicus University, 53-59 Św. Józefa St, 87-100, Toruń, Poland.

Background: Transpapillary biliary drainage in ERCP is an established method for symptomatic treatment of patients with unresectable malignant biliary obstruction. Percutaneous transhepatic biliary drainage frequently remains the treatment of choice when the transpapillary approach proves ineffective. Recently, EUS-guided extra-anatomical anastomoses of bile ducts to the gastrointestinal tract have been reported as an alternative to percutaneous biliary drainage. Read More

Is the Anterior Injection Approach Without Ultrasound Guidance Superior to the Posterior Approach for Adhesive Capsulitis of the Shoulder? A Sequential, Prospective Trial.

Clin Orthop Relat Res 2021 May 5. Epub 2021 May 5.

Z. Rijs, Department of Orthopedic Surgery, Leiden University Medical Center, Leiden, the Netherlands.

Background: Shoulder injections for conditions such as adhesive capsulitis are commonly performed and can be administered through image-based or landmark-based injection approaches. Ultrasound-guided injections are widely used and accurate because ultrasound allows real-time visualization of the needle and injected contrast. Landmark-based injections would be advantageous, if they were accurate, because they would save the time and expense associated with ultrasound. Read More
