Aim: To establish the clinical value of endoscopic papillectomy for duodenal papillary tumor based on endoscopic and clinical characteristics.

Patients and methods: This single-center, retrospective study included 110 patients with duodenal papillary tumor who underwent endoscopic papillectomy between January 2006 and April 2017 at the gastrointestinal endoscopic center of the Chinese PLA General Hospital. Clinical data, postoperative pathology, procedure-related complications, and therapeutic outcomes were analyzed.

Results: Endoscopic papillectomy was technically feasible in all patients, and was mainly performed by four experienced endoscopists. The primary success rate of endoscopic papillectomy for ampullary neoplasms was 78.2%. A total of 13 patients experienced recurrence during a mean follow-up period of 16.28 months (range 6-132 months), the predictive factors that were related to recurrence were complete resection (53.8% vs. 94.2%; P = 0.001), and final pathology findings (P = 0.001). Delayed hemorrhage, the most common procedure-related complication, occurred in 20% (22/110) of patients and was significantly related to intraoperative bleeding (P = 0.042). Pancreatitis was the second most common complication, which was closely related to intraoperative bleeding requiring intervention (P = 0.040) and larger tumor size (P = 0.044). Histology, type of resection, stent placement, sphincterotomy, and duration of procedure were not related to post-procedure hemorrhage or pancreatitis. Older age (63.7 ± 13.5 vs. 57.4 ± 12.2; P = 0.033), jaundice (47.8% vs. 13.8%; P = 0.001), endoscopic forceps biopsy diagnosis of high-grade intraepithelial neoplasia (82.6% vs. 14.9%; P = 0.001), tumor size ≥ 2 cm (60.9% vs. 34.5%; P = 0.022), and dilation of the bile duct (34.8% vs. 9.2%; P = 0.006) were clinical features for ampullary carcinoma. The rate of complete resection (52.2% vs. 92.0%; P = 0.001) and recurrence (34.8% vs. 6.8%; P = 0.001) were also related to the diagnosis of ampullary carcinoma at final pathology.

Conclusions: Endoscopic papillectomy is a feasible and reasonable option for both diagnosis and treatment of tumors of the duodenal papilla in properly selected patients.
