Abstract:
Objective To assess the feasibility,safety and efficacy of endoscopic papillectomy (EP) for tumors at the ampulla of Vater (AV).Methods A total of 15 patients with tumor at AV that were indicated for EP were included in this prospective study.Their clinical profiles,procedural parameters and outcome were evaluated.Results All patients underwent EP procedure successfully.Four patients who were diagnosed as having chronic inflammation in the reference endoscopy were confirmed as having adenoma after EP.Out of the 11 patients who were previously diagnosed as andenoma on biopsy,2 of low differentiated adenocarcinoma,1 of well differentiated adenocarcinoma and 1 malignant transformation were pathologically confirmed after EP.Stents were implanted in 8 patients with dilated pancreatic and/or common bile duct.Except for 2 cases of melena and 2 transient elevated level of blood amylase after EP,no other major complications occurred.Three patients,including 1 case of low-differentiated adenocarcinoma,1 case of malignant transformation and 1 case of lesion residual,were referred to surgery,another patient with low-differentiated adenocarcinoma declined any additional intervention because of old age.In the remaining 11 cases ( 11/15,73.3％ ) including one well differentiated adenocarcinoma,no recurrence was observed during a follow-up period of 23.4 (5 to 47) months.Conclusion EP is a minimal invasive,safe and effective treatment for tumors at AV,which also can provide an accurate staging of the lesion.
