Is salvage treatment necessary after incomplete resection of rectal neuroendocrine tumors: A systematic review and meta-analysis

Figure 2 Incomplete resection rate by initial resection method. The forest plot shows pooled incomplete resection rates across different primary endoscopic techniques based on 17 studies[19,20,24,27,28,30,33,34,37,40-42,46-50]. Cold snare polypectomy exhibited the highest rate (73.1%), whereas endoscopic submucosal dissection had the lowest rate (14.7%). Conventional endoscopic mucosal resection and modified endoscopic mucosal resection had intermediate incomplete resection rates. This figure emphasizes the impact of the resection technique on histological completeness. CSP: Cold snare polypectomy; cEMR: Conventional endoscopic mucosal resection; mEMR: Modified endoscopic mucosal resection; ESD: Endoscopic submucosal dissection.
