title: Treatment patterns and costs associated with sessile colorectal polyps.
abstract: OBJECTIVE
  Because of the paucity of existing literature on treatment and costs associated with sessile lesions, the objectives of this study were to perform a retrospective analysis on patients with sessile polyps to identify patient and polyp characteristics, to determine treatment patterns, and to estimate the cost of treating these patients.
  
  
  METHODS
  We conducted a retrospective, observational cohort study of 280 patients who presented to a large teaching hospital between 1997 and 2000 with at least one sessile or broad-based pedunculated colorectal polyp of any size or histology, not including adenocarcinoma greater than stage T1.
  
  
  RESULTS
  Mean polyp size was 1.3 cm, and two thirds of polyps were removed in a single procedure. The number of repeat procedures increased with polyp size (Kendall T-b = 0.47; 95% CI = 0.39-0.55). Patients with polyps > or = 2 cm were 5.88 times more likely than patients with smaller polyps to undergo a surgical procedure. Surgical procedures required 88.01 min longer than nonsurgical procedures (95% CI = 74.43-102.42). Mean total cost of treatment was $2,038 (range $153 to $14,838). Open resection ($6,165) was the most costly surgical procedure, and piecemeal polypectomy ($892) was the most costly nonsurgical therapeutic procedure.
  
  
  CONCLUSIONS
  One third of polyps required more than one procedure. Surgical procedures accounted for the majority of resource use in this sample. Finally, patients with polyps > or = 2 cm incurred almost half the total costs while accounting for only 22% of the sample. The greatest economic gains could be made by improving efficiency of polyp removal for these patients.
