Abstract
Background
Endoscopic removal of benign tumours of papilla is increasing. Our aim was to evaluate the outcome of endoscopic resection of papillary tumours.
Methods
In the years 2000–2012, 61 papillectomies were performed in Helsinki University Central Hospital. The cases were analysed retrospectively.
Results
There were 35 patients with benign tumour of papilla without familial adenomatous polyposis (FAP), 16 patients with FAP and 10 patients with ampullary cancer. Jaundice and bile duct dilation were risk factors for malignancy (p < 0.001). In benign tumours, the recurrence rate was 25.5 %. In 5/51 benign tumour cases (9.8 %), a pancreaticoduodenectomy was performed. The remaining cases were treated endoscopically. Neither tumour size, resection in one piece or piecemeal technique, nor coagulation of resection margins had an effect on the development of residual tumour. The total complication rate was 24.6 %. Pancreatitis developed in six patients (9.8 %, 3 mild and 3 moderate). In benign tumour cases, pancreatic stent decreased pancreatitis rate (p = 0.045). In cases where only a pancreatic sphincterotomy was performed, the risk of pancreatitis was high 4/7 (57 %). Bleeding was the most common complication (18 %). Only one patient was operated due to complication, a post-papillectomy bleeding. In six out of seven non-operated cancer patients, the disease progressed.
Conclusion
Endoscopic papillectomy is an effective procedure for treating benign papillary tumours. Jaundice and bile duct dilation are more common in malignant tumours. Pancreatic stent decreases the risk of post-papillectomy pancreatitis. Pancreatic sphincterotomy without stenting carries a high risk of pancreatitis. For papillary cancer, surgery is recommended.
