Background and aims
Sporadic non-ampullary duodenal adenomas (SNDAs) are often referred to tertiary centers because of the challenges in endoscopic resection. There is a paucity of data on both technical and clinical outcomes. The aim of our study was to evaluate the efficacy and safety of endoscopic resection for the treatment of SNDA in two western centers.
Methods
This is a retrospective study reporting data of a cohort of patients referred for resection of SNDA between 2013 and 2017. Patients with familial adenomatous polyposis or ampullary lesions were excluded from present analysis. Outcomes considered for this study were technical success, adverse events, recurrence and need for surgery.
Results
120 patients (mean age 66 ± 11.9 years, 64male) were enrolled in the study. Mean size of the lesions was 23.3 mm (range 5–80). Fifty-six en-bloc endoscopic mucosal resection (EMR) (46.6%), 41 piecemeal EMR (pEMR) and 23 endoscopic submucosal dissection were performed. Intra-procedural perforation was observed in 4 patients (3.3%). Fourteen post-procedural (11.6%) adverse events were recorded. All post-procedural perforations occurred in lesions > 30 mm. Recurrence was observed in 11 patients (9.5%) during a mean follow-up of 29 months. All recurrences were successfully managed endoscopically. 119 patients were still alive at last follow-up.
Conclusion
Endoscopic resection can be successfully carried out in majority of patients. Size > 30 mm seems to be the predictor of high adverse events risk.
