    Abstract:
    BACKGROUND/AIMS: Limited data exist regarding the natural history of duodenal carcinoid tumors and the efficacy of endoscopic treatment. METHODS: A total of 27 patients with duodenal carcinoid tumors were enrolled. All tumors were located outside the periampullary region and were ≤10 mm in size. 11 patients underwent endoscopic mucosal resection (EMR) and argon plasma coagulation (APC). 13 patients did not undergo any specific procedure for tumor removal and were followed clinically. RESULTS: Of 13 patients not undergoing treatment, tumors disappeared in 5 cases during follow-up with diagnostic forceps biopsy. Endoscopically visible lesions remained in the last follow-up endoscopy in 8 patients (61.5%). No lymph node or distant metastases or tumor-related deaths occurred during a median follow-up of 37 months. Of 11 cases treated with EMR, tumor-free resection margins were achieved in 10 cases and no local recurrence occurred after treatment. Two perforations occurred during EMR. Of the 3 cases treated with APC, local recurrence occurred in 1 case. CONCLUSIONS: Given the risks associated with EMR and the likely favorable natural history of small duodenal carcinoid tumors, conservative management with close follow-up may represent a viable alternative to endoscopic treatment, especially in patients with a high risk of perioperative complications.
