Low-dose pulsed vs standard pulsed fluoroscopy during ERCP to reduce radiation without change in image quality: Prospective randomized study.

Endoscopic retrograde cholangiopancreatography (ERCP) poses the risk of radiation exposure (RE) to patients and staff and increases the risk of adverse biological effects such as cataracts, sterility, and cancer. Newer fluoroscopy equipment (C-Arm) provides options to limit radiation in the form of lower radiation dose and frame rate or time-limited "pulsed" settings. However, the impact of lower settings on image quality has not been assessed, and no standard protocol exists for fluoroscopy settings used during ERCP.

Recognizing intrapancreatic accessory spleen via EUS: Interobserver variability.

Background And Objective: Accessory spleen (AS) may be encountered as an intrapancreatic lesion on EUS. This can look similar to other pancreatic pathologies and may lead to unnecessary interventions. The goal of this study was to evaluate the accuracy of EUS in distinguishing intrapancreatic AS (IPAS) from other pancreatic lesions.

Carcinoid tumor causing ileoceccal intussusception in an adult patient.

: Little is known about adult intussusception, but current evidence suggests that malignancy, polyps, and diverticula are usual etiologies. We present a case of adult ileoceccal intussusception secondary to carcinoid tumor. : A 53-year-old African American male presented with hematochezia and non-radiating constant left upper quadrant pain accompanied by nausea and vomiting.

Comparison of the Diagnostic Yield of EUS Needles for Liver Biopsy: Ex Vivo Study.

Background And Aims: EUS-guided liver biopsy is an emerging method of liver tissue acquisition which is safe and had been shown to produce excellent histological yield. There is limited data comparing the diagnostic yield of different FNA needles. We aimed to compare the diagnostic performance of four commercially available 19-gauge FNA needles.
