title: Endoscopic resection for rectal carcinoid tumors: comparison of polypectomy and endoscopic submucosal resection with band ligation.
abstract: OBJECTIVE
  Rectal carcinoid tumors, at diagnosis, are as small as 10 mm or less in about 80% of patients. These tumors are generally removed by endoscopic resection. The aim of this study was to compare treatment efficacy and safety between endoscopic submucosal resection with band ligation (ESMR-L) and conventional polypectomy.
  
  
  METHODS
  Between January 2005 and September 2010, a total of 88 patients, who visited at Busan Paik Hospital and Kosin University Gospel Hospital for endoscopic resection of rectal carcinoid, were reviewed, retrospectively.
  
  
  RESULTS
  Thirty-three cases were treated by ESMR-L, and 55 cases by conventional polypectomy. There were no significant difference in the size of tumor between ESMR-L group and polypectomy group (6.02±2.36 vs. 6.49±3.24 mm, p=0.474). The rate of positive resection margin was significantly lower in ESMR-L group (2/33, 6.1%) than in polypectomy group (19/55, 34.5%; p=0.002). The rate of positive vertical resection margin, among others, was markedly lower in ESMR-L group (1/33, 3.0%) compared to polypectomy group (19/55, 34.5%; p<0.001).
  
  
  CONCLUSIONS
  ESMR-L, rather than conventional polypectomy, is a useful treatment option for removal of rectal carcinoid tumors less than 10 mm in diameter.
