title: Long-term follow-up of patients with endoscopic treatment of sporadic adenomas of the papilla of vater.
abstract: OBJECTIVE
  Knowledge about the long-term outcome of patients after endoscopic treatment of ampullary adenomas remains poor, although surgical series have suggested that the initial endoscopic evaluation of these diseases might overlook cancer foci developed in adenomas. The aim of this study was to evaluate retrospectively the long-term outcome in patients with ampullary adenomas treated endoscopically, with a focus on the possible development of cancer.
  
  
  METHODS
  The study included 24 patients (median age 59 years, range 34 - 84) with macroscopically benign adenomas of the papilla of Vater treated using mainly laser photodestruction between 1983 and 1996. Medical, endoscopic, surgical, and histological reports were reviewed. Patients and general practitioners were contacted to determine patient outcome when endoscopic follow-up had been discontinued.
  
  
  RESULTS
  Endoscopic remission (macroscopic and histological) was achieved in 16 patients (66.6 %) with one recurrence (6.2 %) during a mean endoscopic follow-up of 66 months (4-168 months). Endoscopic treatment was discontinued in five (20.8 %) patients (with minimal residual adenoma and advanced age and/or severe unrelated disease), and failed in three patients (12.5 %) (failure of Nd:YAG laser in one case, severe pancreatitis and pancreatic duct ingrowth in one case each). After a mean clinical follow-up of 81 months (8-172 months), two patients (8.3 %) had undergone pancreaticoduodenectomy; eight (33.3 %) had died from unrelated diseases; and 14 (58.3 %) were alive and asymptomatic without any evidence of ampullary cancer.
  
  
  CONCLUSIONS
  Long-term follow-up revealed no case of advanced ampullary cancer and suggested that endoscopic treatment was satisfactory for the large majority of patients with ampullary adenomas.
