A CASE OF EARLY DUODENAL CANCER ON THE ORAL PROTRUSION OF THE MAIN PAPILLARY TUMOR RESECTED BY ENDOSCOPIC SNARE EXCISION

Abstract

A 62-year-old female was diagnosed as having a well-differentiated adenocarcinoma of the main papilla. Endoscopic ultrasonography showed that the tumor was limited to the mucosa of the duodenum. Abdominal ultrasonography and CT findings showed no evidence of lymph node swelling or metastasis (clinical stage T1). The patient gave informed consent for endoscopic snare excision. On histological findings of the resected specimen, a well-differentiated adenocarcinoma limited to the oral protrusion of the main papilla, (size 5 mm, m, ly0, v0, cut end (-), final stage pT1) was diagnosed. One year and two months after the endoscopic snare excision, no evidence of recurrence has been noted.
