GI & Hepatology Pathology Series: Part One


Access Part Two of this Activity

A free educational resource specifically for GI fellows, these presentation slides were developed by John T. Woosley, MD, PhD, professor and pathologist at the University of North Carolina at Chapel Hill, from cases encountered in his daily diagnostic practice.

The slides are instructional and interactive with embedded audio narrations, which can be used for self-assessment. Over time, the teaching set will gradually encompass all of the histological entities that a GI fellow should be familiar with.

Physicians preparing for GI board recertification can also use the slides for a more robust study regimen.

Reviewing the Slides

The slide sets have been organized into organ-based sections and have been labeled as single cases by diagnosis.

Internet Explorer Users

The slides are formated to automatically be viewed as a slide show upon download. If viewing the slides through Internet Explorer, this function is not readily applied. You will need to follow the steps below to view as a slide show:

  1. Click on the presentation you would like to view (i.e., stomach, small bowel, etc.)
  2. You will be prompted to “Open” or “Save” the file. Click “Open.”

    Note: All presentations are read only and have been protected from editing and/or modifying.

  3. Once the file has opened in PowerPoint, click “View” on the tool bar.
  4. Select “Slide Show.”

Other Web Browser Users

To hear the audio narrative embedded on the slides, follow these steps:

  1. Click on the title slide. Once the slide loads, move your cursor/arrow on any area of the slide.
    • The cursor/arrow will change into a hand on areas of the slide where there is embedded audio.
  2. To move to the next slide, right click your mouse and select “Next” on the menu or simply press “Enter” on your keyboard.
