Clinical Manifestations and Stool Load of Atypical Enteropathogenic Escherichia coli Infections in United States Children and Adults.

Background & Aims: There is debate whether atypical enteropathogenic Escherichia coli (aEPEC) causes disease in adults. aEPEC is commonly detected in symptomatic and asymptomatic individuals. aEPEC, in contrast to typical EPEC, lacks bundle-forming pili, altering its pathogenicity.

Increased Risk of Pancreatitis after Endoscopic Retrograde Cholangiopancreatography Following a Positive Intraoperative Cholangiogram: A Single-Center Experience.

Background/aims: To determine if patients with a positive intraoperative cholangiogram (IOC) who undergo a subsequent endoscopic retrograde cholangiopancreatography (ERCP) have an increased risk of post-ERCP pancreatitis (PEP) compared to those who undergo ERCP directly for suspected common bile duct stones.

Methods: A retrospective case-control study was performed from 2010 to 2016. Cases included inpatients with a positive IOC at cholecystectomy who underwent subsequent ERCP.

The Utility of Endoscopic Ultrasound in Patients with Isolated Elevations in Serum Amylase and/or Lipase.

Background/aims: The aim of this study was to describe the diagnostic yield of endoscopic ultrasound (EUS) in patients with isolated elevated levels of amylase and/or lipase.

Methods: A retrospective chart review was conducted at a large academic medical center from 2000 to 2016. Patients were selected based on having elevated amylase, lipase, or both, but without a diagnosis of pancreatitis or known pancreatobiliary disease.

Sclerosing angiomatoid nodular transformation of the spleen masquerading as a sarcoma metastasis.

We report a case of sclerosing angiomatoid nodular transformation (SANT) of the spleen presenting as an incidental splenic mass in a patient with a history of retroperitoneal spindle cell sarcoma. Imaging studies and preoperative fine needle biopsy failed to differentiate this lesion from other vascular splenic lesions or a metastatic focus of a prior sarcoma. The patient was treated with splenectomy, which has proved both diagnostic and therapeutic in this and other cases of SANT.
