[Endoscopic treatment of duodenal Brunner adenoma].

OBJECTIVE: To evaluate the value of endoscopic treatment for duodenal Brunner adenoma.

METHODS: Twenty-nine cases of duodenal Brunner adenoma were diagnosed by pathology between November 2006 and May 2010 in the Endoscopy Center of Zhongshan Hospital. The clinical data were retrospectively analyzed.

RESULTS: In 29 cases, there were 13 males and 16 females. The median age was 55(29-72) years. The mean adenoma diameter was (1.7 ± 0.1) cm, among which 17 adenomas ranged from 0.5 to 1.0 cm, 6 ranged from 1.0 to 2.0 cm, and 6 greater than 2.0 cm. Nine cases were treated by polypectomy, 12 by endoscopic mucosal resection (EMR), and 8 by endoscopic submucosal dissection(ESD). En-bloc resection rate was 100%. Intraoperative bleeding was seen in one case (200 ml), managed by nonsurgical method, including electrocoagulation, metal clips and nylon rope. Perforation occurred in 1 case during the procedure and was managed by metal clips. Delayed bleeding occurred in 1 case in the second day and was managed endoscopically. During a median follow-up of 13 (range, 2-39) months, the quality of life was satisfactory in this cohort, and no patients developed long-term complications. There was one recurrence within 1 year after the procedure and a second ESD was performed.

CONCLUSION: Endoscopic treatment is technically feasible and may be considered as the procedure of choice for duodenal Brunner adenoma.
