title: Endoscopic therapy of adenomas of the papilla of Vater. A retrospective analysis with long-term follow-up.
abstract: OBJECTIVE
  To compare the efficacy and the complication rate between endoscopic snare resection of adenomas of Vater's papilla and endoscopic palliation.
  
  
  METHODS
  In a retrospective, non randomized manner, we compared long-term results of our endoscopic strategies in 36 patients with histologically confirmed adenoma of Vater's papilla submitted either to local endoscopic snare resection (n=18) or to simple endoscopic palliation (n= 18), respectively.
  
  
  RESULTS
  Between 1985 and 1998 results were reviewed. Median age was 76.5 (range 42-89) years in the palliation, and 64.0 (23-89) years in the endoscopic snare resection group. Median duration of follow-up was 33 (6-135) and 75.0 (27-123) months, respectively. The incidence of adenocarcinoma of Vater's papilla was 1 per 52.8 patient-years after endoscopic snare resection and 1 per 15.5 patient-years in the group treated with endoscopic palliation. Compared to the results of endoscopic palliation (prosthesis, sphincterotomy), we found a significant reduction of carcinoma-related death (p=0.0045, McNemar) and adenoma carcinoma-sequence (p=0.007, McNemar) after snare resection.
  
  
  CONCLUSIONS
  This retrospective study suggests that complete endoscopic snare resection of adenomas of Vater's papilla will lead to a lower rate of adenoma-carcinoma sequence, to a lower carcinoma-related death rate and probably improves patient survival. These results should be proven prospectively.
