About the Journal

ACG Case Reports Journal is a peer-reviewed, open-access publication that provides GI and hepatology fellows, private practice clinicians, and other healthcare providers an opportunity to share interesting case reports with their peers and with leaders in the field. The Journal is edited by a team of GI and hepatology fellows led by Editor-in-Chief Samuel Han, MD. Issues are published online bi-weekly for free to all readers, including ACG non-members, and feature images and video clips in addition to case descriptions. ACG Case Reports Journal does not charge submission or publication fees for authors.

The ACG Case Reports Journal was created to help fulfill ACG’s commitment to providing growth and learning opportunities for GI and hepatology fellows, and helps fellows meet core curriculum requirements for non-patient care activities. All case submissions must have a GI and hepatology fellow in training or a resident interested in pursuing fellowship as the lead author. Cases authored by private practice clinicians and other healthcare providers who might traditionally face difficulty publishing with leading journals are also welcome.
