Study summary

The study validates prospectively a new endoscopic scoring system (Gothenburg Intestinal Transplant Endoscopy Score, GITES) designed to summarize and stratify the abnormal ileal endoscopic findings after intestinal transplantation. GITES is a five-tier, four grade score which asseses mucosal friability, mucosal erythema and mucosal injury (ulcerations) as well as villous changes according to severity. These features (i.e., endoscopic descriptors) are also grouped from mild to very severe in the same sequence as observed during the progression of several pathologic conditions encountered after intestinal transplantation (acute rejection, infectious enteritis).

What researchers measure

Primary outcomes

  1. Endoscopic evaluation

    To validate the GITES grading system in intestinal graft recipients using high-definition white light endoscopy

    Time frame: 7 years

Secondary outcomes

  1. Correlations with histology and Clinical course

    Comparison and correlation of clinical and histopathological data with endoscopic findings to evaluate the conditions leading to the mucosal alterations defined by established endoscopic descriptors and GITES.

    Time frame: 1 year

  2. Performance of the grading score

    Endpoints include sensitivity, specificity, positive predictive value, negative predictive value as well as inter- and intraobserver variation in the evaluation of the mucosal alterations by means of GITES and using high-definition white light endoscopy;

    Time frame: 1 year
