A CASE OF ENDOSCOPIC SNARE PAPILLECTOMY FOR A CARCINOID TUMOR OF THE MAJOR DUODENAL PAPILLA

Abstract

The patient was a 65 year-old female, who was admitted because of cholangitis. ERCP revealed an elevated lesion of the duodenal major papilla looking like a submucosal tumor and endoscopic biopsy specimens revealed a carcinoid tumor. EUS demonstrated that the tumor was 5mm in diameter and located at the submucosal layer. As we diagnosed that the tumor invasion was limited within the submucosal layer, without clinical evidence of regional lymphadenopathy, endoscopic snare papillectomy was performed. Histological examination of the resected specimen revealed a carcinoid tumor the surgical margin of being free neither horizontal nor vertical, and also showed that there was no vascular infiltration. Up to now, there has not been the evidence of tumor recurrence after one year and six months.
