Background
Endoscopic papillectomy is a viable therapy in ampullary lesions. Prior studies have reported on outcomes of sporadic ampullary lesions, and only small cohort studies have reported outcomes associated with familial adenomatous polyposis (FAP) syndrome.
Aims
We performed a systematic review with pooled analysis to assess the safety and efficacy of EP for treating ampullary adenomas in FAP.
Methods
We performed a comprehensive literature search of major databases from inception to May 2020. Studies that included patients with endoscopically resected ampullary lesions and FAP were eligible. The rate of technical success, en bloc resection, piecemeal resection, recurrence, and adverse events was pooled by means of a random-effects model to obtain a proportion with a 95% confidence interval (CI).
Results
Six studies, including a total of 99 patients, were included in our final analysis. Patient age ranged from 28 to 91 years. Pooled technical success was 90.3% (CI 76.9–96.3%, I2 = 31%). Rate of en bloc resection was 60.6% (CI 47.9–72.0%, I2 = 0%). Recurrence rate was 25.4% (5.7–65.9%, I2 = 82%). The post-procedural pancreatitis rate was 14.7% of which 68% (51 of 75) utilized prophylactic pancreatic stenting. Other adverse events included bleeding (9.2%) and perforation (4%).
Conclusion
Endoscopic papillectomy offers high technical success but remains challenging in patients with FAP, particularly due to high recurrence rates.
