title: Does endoscopic mucosal resection for large colorectal polyps allow ambulatory management?
abstract: BACKGROUND
  Endoscopic mucosal resection (EMR) is an efficacious endoscopic therapy for large adenoma or confined neoplasia. The most frequent complication is delayed hemorrhage, and hemoclips appear to be an effective therapeutic option. The aim of this study was to determine if large EMR could allow ambulatory management.
  
  
  METHODS
  Colorectal polyps ≥20 mm in size treated by EMR in one endoscopy unit were prospectively included. The period from September 2007 to September 2008 was considered as the reference period (period 1). From September 2008 on, patients were hospitalized in an ambulatory unit. Periods from September 2008 to September 2009 (period 2), from September 2009 to September 2010 (period 3), and from September 2010 to September 2011 (period 4) were compared to the reference period. Patients receiving anticoagulation drugs were excluded from the study.
  
  
  RESULTS
  A total of 138 patients were treated by 139 EMRs for large colorectal polyps. EMRs were completed by at least one clip per centimeter in 10.7 %, 30.2 % (p = NS), 50 % (p = 0.015), and 76 % (p = 0.001). Ambulatory EMRs were performed in 21 %, 52.4 % (p = 0.008), 67.6 % (p = 0.02), and 88.2 % (p = 0.004) of cases during periods 1, 2, 3, and 4. The complication rate was stable during the four periods. No patients with more than one hemoclip per EMR centimeter experienced delayed bleeding.
  
  
  CONCLUSIONS
  The low complication rate during the four periods allows us to consider ambulatory EMR for large colorectal lesions ≥20 mm in diameter as an option. One hemoclip per centimeter may help prevent delayed hemorrhage in patients without anticoagulation drugs.
