To compare the efficacy of endoscopic mucosal resection using band ligation(EMR-b) and endoscopic mucosal dissection(ESD) in the treatment of rectal neuroendocrine tumors(NENs).
The data of 56 rectal NENs patients with rectal NENs < 10 mm in diameters, without lymphatic metastasis treated by ESD or EMR-b were retrospectively analyzed. According to different treatments, the patients were divided into EMR-B group (26 cases) and ESD group (30 cases). The complete resection rate, incidence of complications, and length of procedures were compared between the two groups.
The mean age was (51.05±11.31) years old of 56 cases. The tumor size of EMR-B group was (7.12±2.76) mm, and was (7.47±2.32) mm in the ESD group, and the between-group difference in tumor size showed no significant difference (P=0.599). The resection time in EMR-B group was (9.08±3.45) min, which was shorter than (18.50±3.25) min in the ESD group, and the difference was statistically significant(P < 0.001). The complete resection rate of the EMR-B group was 92.31% (24/26), and was 93.33% (28/30) in the ESD group, and the difference was not statistically significant (P=1.000). In the cases of incomplete resection, there was neither local recurrence nor distant metastasis during the follow-up.
Compared with ESD, EMR-b has similar histological complete resection rate, but has shorter resection time and simpler operation. EMR-b may be a better choice for rectal NENs with diameter < 10 mm and without invasion of submucosa.
