Introduction Rectal neuroendocrine tumors (NETs) are often found incidentally during screening colonoscopy and can be resected using various endoscopic techniques. This study aimed to compare the safety and efficacy of endoscopic mucosal resection after precutting (EMR-P). Patients and Methods Between August 2002 and January 2013, 120 lesions (118 patients) underwent endoscopic submucosal dissection (ESD) (n=47), conventional EMR (n=38) or EMR-P (n=34) for rectal NETs. The rate of endoscopic complete resection, pathologic complete resection, complications, procedure time and recurrence were analyzed retrospectively. Results The endoscopic complete resection rate was significantly higher in the ESD (100%), EMR-P group (100%) compared with the EMR group (84%) (p=0.039). The pathological complete resection rate was lower in EMR group (62.3%), but not significantly higher in ESD group (89.7%) when compared with EMR-P group (82.6%). The procedure time was significantly shorter in EMR-P group (22.5 minutes) compared with ESD group (36.8 minutes) (p=0.042). Overall complication rate was not significantly different among the 3 groups. No recurrence has been detected in 3 groups. Conclusions EMR-P might be a feasible treatment technique for small rectal NETs. It showed more convenient than ESD, and more effective than EMR. |
