Background

The reliability and reproducibility of scoring endoscopic recurrence is of utmost importance because it generally determines initiating postoperative medical therapy and it is used as outcome parameter in clinical trials. Variability in endoscopic scoring may result in inappropriate therapeutic decisions and study conclusions. It is hypothesised that different types of anastomoses have an influence on scoring endoscopic recurrence using the Rutgeerts’ score. The aim of this study is to analyse to what extent the ulcerations are determined by the type of anastomosis and how it interferes with the scoring of Crohn’s recurrence.

Methods

This is a retrospective review of endoscopy videos to re-assess endoscopic recurrence. All videotapes of the ileocolonoscopy were blinded and scored by a trained gastroenterologist (MD) and a surgeon (WB). Videos were excluded if the quality of the video was low or if the anastomosis was not visualised properly. The primary outcome is the presence of ulcerations six months after surgery, on individual parts of the anastomosis: inverting stapled anastomosis (side to side conjunction) and everting type of junction (transection ends). In the latter group, at least one site – colon, ileum or both – was scored.


Results

Of 99 available endoscopy videos, eighty-nine eligible patients were included in this retrospective study for analysis. The inverting and everting stapled anastomosis were scored individually using the SES-CD. A SES-CD of zero was found in 21/89 (23.6%) of the inverting anastomoses versus 74/75 (98.67%) in the everting anastomoses.

This study demonstrated a significant difference in wound healing of the inverting anastomosis versus the everting anastomosis. Inverting anastomoses show ulcerations and a circular scar long after surgery irrespective of the presence of ulcerations of terminal ileum. A normal wound healing phenomena might mistakenly be seen for recurrent Crohns’ disease. Everting anastomosis, on the contrary, heal without residue.
