The Munich Polypectomy Study (MUPS): prospective analysis of complications and risk factors in 4000 colonic snare polypectomies.

Background And Study Aims: Screening colonoscopy with polypectomy has been shown to reduce the morbidity and mortality associated with colorectal cancer. However, there is a lack of large and systematic prospective studies of the complications of polypectomy.

Patients And Methods: Data on all snare polypectomies performed in 13 institutions (six hospitals and seven gastroenterology offices) were recorded prospectively during a 20-month period, including data on a 30-day follow-up period.
