This study aimed to investigate the long-term outcomes of cold snare polypectomy for superficial non-ampullary duodenal epithelial tumors (SNADETs). The results showed that CSP is a safe and effective procedure with a high en-bloc resection rate and long-term local control capability.
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.
