Retrospective analysis of endoscopic resection of duodenal papilla adenoma
Objective To investigate the safety and efficacy of endoscopic resection of duodenal papilla adenoma.Methods Clinical data of 10 patients undergoing endoscopic duodenal papilloma resection from the Digestive Endosco-py Center in General Hospital of Xinjiang Military Region,Chinese PLA from Jun.2019 to Sep.2022 were retrospec-tively analyzed,and their endoscopic manifestations,complications,pathological characteristics and follow-up were sum-marized.Results A total of 10 patients were included in this study,including 2 females and 8 males.Patients ranged in age from 54 to 73 years old,with an average age of 63 years old.On admission,3 cases were complicated with dys-pepsia,4 cases were found by physical examination,asymptomatic biliary dilatation occurred in 2 cases.Intraductal ex-tension in 1 case,and lesions were confined to the ampulla in 9 patients.One case was intraductal extension adenoma.The average lesion size was 20.4 mm(8.0-33.0 mm).Eight lesions were resected en masse,and 2 lesions were resec-ted en masse.Biliary and pancreatic duct stents were implanted in 6 cases.Nine cases were completely resected,1 case had positive residual margin,and the success rate was 90%.Complication rate was 40%(4/10):3 cases bleeding;3 cases had mild acute pancreatitis,1 case perforated and 3 cases relapsed.There were 2 cases of tubular adenoma,3 ca-ses of high-grade intraepithelial neoplasia,3 cases of villous adenoma,1 case of low-grade intraepithelial neoplasia,and 1 case of adenocarcinoma,with positive incisal margin and a completely negative incisal margin rate of 90%.Conclusion Endoscopic resection of duodenal papilla adenorma is a high-risk and effective minimally invasive treat-ment.Pancreatic duct stent placement can reduce the incidence of pancreatitis.Close endoscopic follow-up should be conducted after surgery to timely deal with recurrence and residual.
