    Cathepsins regulate premature trypsinogen activation within acinar cells, a key initial step in pancreatitis. The identity, origin, and causative roles of activated cathepsins in pancreatic inflammation and pain are not defined. By using a near infrared-labeled activity-based probe (GB123) that covalently modifies active cathepsins, we localized and identified activated cathepsins in mice with cerulein-induced pancreatitis and in pancreatic juice from patients with chronic pancreatitis. ...

    BACKGROUND & AIMS: The prevalence and significance of digestive manifestations in coronavirus disease 2019 (COVID-19) remain uncertain. We aimed to assess the prevalence, spectrum, severity, and significance of digestive manifestations in patients hospitalized with COVID-19.

    METHODS: Consecutive patients hospitalized with COVID-19 were identified across a geographically diverse alliance of medical centers in North America. Data pertaining to baseline characteristics, symptomatology, ...

    Background and study aims The role of the digital single-operator pancreatoscopy (D-SOP) with electrohydraulic (EHL) or laser lithotripsy (LL) in treating pancreatic ductal stones is unclear. We investigated the safety and efficacy of D-SOP with EHL or LL in patients with obstructing pancreatic duct stones.

    Patients and methods Retrospective analysis of 109 patients who underwent D-SOP for pancreatic stones at 17 tertiary centers in the United ...

    BACKGROUND AND AIMS: EUS-guided FNA or biopsy sampling is widely practiced. Optimal sonographic visualization of the needle is critical for image-guided interventions. Of the several commercially available needles, bench-top testing and direct comparison of these needles have not been done to reveal their inherent echogenicity. The aims are to provide bench-top data that can be used to guide clinical applications and to promote future device research and development.

    METHODS: Descriptive ...

    BACKGROUND AND AIMS: Gastrointestinal manifestations in patients with COVID-19 are common but the role of endoscopy in this patient population remains unclear. We investigated the need for endoscopic procedures, their findings, and impact on patient care in a systematic and geographically diverse sample of patients hospitalized with COVID-19.

    METHODS: As part of the North American Alliance for the Study of Digestive Manifestations of COVID-19, we identified consecutive patients ...

    Percutaneous transhepatic biliary drainage (PTBD) and endoscopic retrograde cholangiopancreatography (ERCP) are widely accepted but competing approaches for the management of malignant obstruction at the hilum of the liver. ERCP is favored in the United States on the basis of high success rates for non-hilar indications, the perceived safety and superior tissue sampling capability of ERCP relative to PTBD, and the avoidance of external drains that are undesirable to patients. A recent ...

    BACKGROUND AND AIMS: The most common symptoms of Covid-19 are respiratory; however, gastrointestinal symptoms are present in up to 50% of patients. We aimed to determine characteristics associated with the development of gastrointestinal symptoms in patients with Covid-19.

    METHODS: A case-control study of adults hospitalized for Covid-19 was conducted across a geographically diverse alliance of 36 US and Canadian medical centers. Data were manually abstracted from electronic health ...
