Table 1 Previous characteristics of patients with recurrent laterally spreading duodenal papillary lesions

Case	Pathological characteristics of initial resected specimen	En bloc resection	Complete resection	The first recurrent time (mo)	Time of follow-up (mo)	Previous endoscopic managements
Case 1	Tubulovillous adenoma with local HIN	Yes	Yes	31	96	Endoscopic snare papillectomy, and multiple APC ablation for adenoma recurrence and three ERCP procedures for biliary stones and acute cholangitis
Case 2	Tubulovillous adenoma with local LIN	Yes	Yes	15	15	Endoscopic snare papillectomy
