AI Article Synopsis
- The study examines the impact of surgically addressing non-R0 resections of rectal neuroendocrine tumors (r-NETs) to prevent disease recurrence.
- It involved a retrospective analysis of 100 patients who underwent endoscopic procedures to remove tumor scars after initial unsuccessful resections.
- The findings indicate that using advanced endoscopic techniques achieved near 100% complete resection (R0) of scars, revealing that residual r-NET was present in 43% of cases.
Article Abstract
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 non-R0 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.
