Abstract

Abstract: Background and Aim: The effectiveness of cold snare polypectomy (CSP) for superficial non‐ampullary duodenal epithelial tumors (SNADETs) regarding long‐term outcomes is not fully clarified. This study aimed to investigate long‐term outcomes of CSP for SNADETs. Methods: Patients diagnosed with sporadic SNADETs and treated with CSP at Chiba University Hospital between March 2015 and May 2018 were retrospectively analyzed. Long‐term outcomes, short‐term outcomes, and adverse events were investigated. Results: In total, 35 patients with 46 lesions were included. The en‐bloc resection rate was 97.8%. Thirty‐seven lesions (80.4%) were diagnosed as adenomatous. The R0 resection rate for adenomatous lesions was 70.3%. Follow‐up investigations more than 12 months after CSP were completed for 35 adenomatous lesions (94.6%). The median observation period after CSP was 48 months. One patient whose observation period was only 3 months died from chronic heart failure with cardiac sarcoidosis 6 months after CSP. No patient died from SNADETs. The relapse‐free survival rate at 12 months after CSP was 97.1%. One recurrence (2.7%) was observed 12 months after CSP. We removed the recurrence lesion with CSP and cold forceps polypectomy. No new recurrence occurred within the observation period. No perforation or post‐operative bleeding occurred for CSP. Conclusions: Cold snare polypectomy for diminutive and small SNADETs is a safe and useful procedure with a high en‐bloc resection rate and long‐term local control capability.
