Treatment of duodenal adenomas with endoscopic argon plasma coagulation.

BACKGROUND

Surgical resection has been the standard treatment for duodenal adenomas. It has a high associated morbidity rate and a significant recurrence rate. The aim of this study was to evaluate endoscopic treatment of these lesions with argon plasma coagulation.

METHODS

We retrospectively identified patients with non-ampullary duodenal adenomas without a polyposis syndrome and who were treated endoscopically between 1st January 1999 and 31st December 2003. Their management, follow up and outcomes were reviewed.

RESULTS

Fifteen patients were included, with mean age 72 years (range 46-85 years). All were treated with at least one session of argon plasma coagulation. Initially, 13 adenomas were macroscopically cleared. Of these, eight (61%) had no recurrence during mean follow up of 40 months (26-68 months). The mean time to recurrence was 14 months (6-30 months). Eradication was possible a second time in four of five recurrent adenomas. There was one complication, of haemorrhage, from 37 sessions of argon plasma coagulation. No patient developed duodenal adenocarcinoma during the study period.

CONCLUSION

Argon plasma coagulation may be safe and effective for the treatment of duodenal adenomas, but further research is required. Progression of adenomas is slow and perhaps no treatment is required.
