Patients and Methods: Between June 2002 and November 2014, a total of 64 patients with pathological T1 (pT1) ampullary carcinoma (25 patients) and pT1 duodenal carcinoma (39 patients) were treated. Of these, 33 patients underwent local resection (LR group), while the other 31 patients underwent pancreatoduodenectomy (PD group). Results: The LR group had 31 patients with pT1a and 2 patients with pT1b. PD group had 18 patients with pT1a and 13 patients with pT1b. One patient with pT1b duodenal carcinoma (20.0%) and one patient with pT1b ampullary carcinoma (10.0%) developed lymph node metastasis, while none of the patients with pT1a disease developed metastases. Conclusion: LR may be considered in the patients preoperatively diagnosed with T1a duodenal carcinoma and T1a ampullary carcinoma. ER -
