Brief 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).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Endoscopic evaluation | 7 years | To validate the GITES grading system in intestinal graft recipients using high-definition white light endoscopy |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Correlations with histology and Clinical course | 1 year | 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. |
| Performance of the grading score | 1 year | 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; |
