title: Endoscopic laser therapy for small villous adenomas of the duodenum.
abstract: Six patients with seven small, nonampullary duodenal villous or tubulovillous adenomas, two of which showed mild dysplasia, were treated by laser photocoagulation. The mean size of the tumors was 19 +/- 16 mm. Both argon and Nd-YAG lasers were used. All tumors were destroyed in one to five sessions. Recurrences of the lesion in two cases were successfully retreated, and both patients remained free of recurrence after 33 and 48 months, respectively. After a median follow-up of 59 months, all patients remained in remission, and five of them are still alive. One died after six months from a bronchogenic carcinoma. After a total of 18 laser sessions, no serious side-effects were observed, two patients exhibiting a transient melena possibly related to the procedure. We conclude that laser therapy is a good alternative to surgery for nonampullary duodenal villous tumors, especially in high-risk patients. Endoscopic follow-up is mandatory to detect and treat recurrence.
