Résumé :

INTRODUCTION: When initial resection of rectal neuroendocrine tumors (r-NETs) is not R0, persistence of local residue could lead to disease recurrence. This study aimed to evaluate the interest of systematic resection of non-R0 r-NET scars. METHODS: Retrospective analysis of all the consecutive endoscopic revisions and resections of the scar after nonR0 resections of r-NETs. RESULTS: A total of 100 patients were included. Salvage endoscopic procedure using endoscopic submucosal dissection or endoscopic full-thickness resection showed an R0 rate of near 100%. Residual r-NET was found in 43% of cases. DISCUSSION: In case of non-R0 resected r-NET, systematic scar resection by endoscopic full-thickness resection or endoscopic submucosal dissection seems necessary.
