Core Tip

Core Tip: This is a multi-center study evaluating the clinical outcomes of 106 patients who underwent endoscopic papillectomy for ampullary adenoma. In our results, margin-positive/uncertain pathologic reports and piecemeal resection were significant factors for the curative resection and recurrences. Unexpectedly, many recurrences were observed in margin-negative resection, but in most cases, they were successfully managed with minimally invasive endoscopic therapies. Since there is no definite factor for predicting and preventing recurrence and re-recurrence, regular follow-up with endoscopy should be performed in every patient regardless of resection margin or resection type, especially in patients with margin-positive/uncertain and piecemeal resection.
